The Death of Ivan Ilych Free Essays

The short story, â€Å"The Death of Ivan Ilych†, written by Leo Tolstoy, is about the reactions of a man and his friends to his suffering and death. Everyone who knows Ivan including Ivan himself has led a life of total disconcern for the feelings and sufferings of others. They all lead shallow lives not daring to probe into the feelings deep down inside for fear of stepping outside the lines of propriety. We will write a custom essay sample on The Death of Ivan Ilych or any similar topic only for you Order Now That is the biggest rule that people of that society follow. Do not say or show what you are thinking. Ivan Ilych’s attitude toward life is the same all the way up to his death. He was as the author put it, â€Å"†¦a capable, good-natured, and social man, though strict in the fulfillment of what he considered his duty: and he considered his duty to be what was so considered by those in authority. † (p. 1088) That quote states that Ivan was solely concerned with his duties and his advancement in position by following the orders of his authorities. Ivan was son of a successful man who held many positions in many departments. That man, Ilya Epimovich Golovin, had three sons. The oldest followed his father’s example and was a success. The youngest son was a total failure. He had blown many opportunities and was the shame of the family. Ivan the middle son was the better of the two. Ivan was a mix of his two brothers. He had the hard-working spirit of the older brother but also appreciates the value of a good time like the younger brother. Ivan’s career grew steadily. In a short time, he eventually obtained the position of examining magistrate. Ivan did very well in this position. He excelled in the separation of the personal duties in his life and the official duties to which he was totally dedicated. This taste of power which came with his new position was very appealing to Ivan. The idea that writing a few words or giving a simple command sent people into motion made Ivan very happy. Upon moving to a new town to take up the position of examining magistrate, Ivan met his future wife, Praskovya Fedorovna Mikhel. Ivan saw her as a â€Å"†¦well connected, and was a sweet, pretty, and thoroughly correct young woman. † The view that she was so within the lines of propriety was the most attractive feature which this young woman possessed in Ivan’s view. At first the marriage which Ivan thought couldn’t hurt his pleasure-seeking life didn’t, then according to Ivan she began to disturb the pleasure and propriety of his life. This ordeal only worsened when his wife became pregnant. She became unbearable to him, overly jealous and coarse, becoming an obstacle to his pursuit of happiness and properness. When the child was born, Ivan realized that a life totally separate his family life would be necessary to fulfill the goals he set for himself. He also came to the realization that to keep his marriage in order that he was going to have to adopt the same attitude to his family that he has to his official duties. Ivan developed an attitude towards his family of complete indifference as stated in the story, â€Å"He only required of it those conveniences—dinner at home, housewife, and bed—which it could give him. † (p. 1092) More children arrived and his wife’s attitude only worsened. After three years and becoming a highly looked upon official he received a promotion to the position of Assistant Public Prosecutor. This new promotion made Ivan like his job even more. Meanwhile, more children were born which made Ivan’s life even more difficult. After getting another promotion and moving to another province, the marriage was getting increasingly difficult. To try and overcome this Ivan decided to spend some time in the country with his wife. This move turns out to be a very bad one. Ivan falls into deep depression and decides that some drastic measures are needed. He returns from the country heading towards St. Petersburg with the objective of obtaining a salary of 5,000 rubles a year. Things worked out very much in his favor. He got a promotion two steps above his former position. After obtaining this position, he returned to the country and his marriage life improved immensely. Ivan then proceeded to the province to which they were moving to attempt to locate a house. He found one which suited his tastes perfectly. Ivan turned his attention towards furnishing his house. He searched for all the things which give his house an air of aristocracy and yet not too snobbish. While showing an upholsterer how he wanted the drapes hung, Ivan fell and nearly caught himself but unfortunately managed to hit himself in the side and give himself a large bruise. This is when the health problems begin. The illness began slowly but the pain steadily increased. Ivan visited many doctors, but none of them could give him a solid diagnosis. The pain caused many problems in his life, most of all it interfered with how he did his job. People began to look down upon him. No one really felt sympathy for Ivan. The people whom he called his friends treated him the same as he treated them in his life, with total indifference. Even Ivan’s own wife treated his illness as a burden and a trouble. He begins to realize how everyone is treating him. All that he wants is pity and there is no one there to give him it besides his servant Gerasim. Ivan shows spots of beginning to realize how he treated life. He treated life with the utmost propriety and tried his very best not to let his emotions get in the way of how he acted and performed his duty. This shows when Ivan says, â€Å"What if my whole life has really been wrong? †(p. 1117) Ivan says this while looking at Gerasim peacefully sleeping at his side, the only one who shows the slightest bit of pity and sorrow for him. Ivan’s wife is falsely concerned in his condition merely because that is the thing for her to be in this situation. She does not really care if he makes it; she is only worried about the inconvenience his suffering is putting her through and the financial bind his death puts her in. Ivan realizes all these things and cannot even bear to speak with her. He thinks to himself, â€Å"Yes, I am making them wretched†¦They are sorry, but it will be better for them when I die. † (p. 1119) All of these things lead up to the conclusion in Ivan’s mind that he is sorry for them. He is trying to act so as not to hurt them. In the final scene someone besides his servant, Gerasim, begins to show pity for him, it is his son. Ivan sees the sorrow and pity in his eyes and apologizes to him for causing this grief. With this story, Leo Tolstoy shows that a man can change. That even if it must be through pain and suffering that everyone is capable of redemption. If a man such as Ivan Ilych who never cared for anyone more than necessary can be redeemed and see the fault in his ways then anyone can. The most selfish man can be changed if people show him pity and feel for him, as he should feel for others. It stirred something inside Ivan when people went out of their way to attempt to comfort him. It made him realize his faults and want to change. How to cite The Death of Ivan Ilych, Essay examples

Question: Discuss about the Primary Health Care. Answer: Primary health care (PHC) is the first point of contact of patients and their family members with the health care system. PHC is based on sound scientific knowledge and application of technology to make health services affordable to all sections of the community. It plays a role in healthy equity by incorporating personal care with health promotion to prevent diseases and facilitate development of the community. Hence, PHC is a universally accessible first level of health care provided by a multi-disciplinary health care team and they interconnect principles of equity, access and empowerment to provide care to sick person (Primary health care, 2017). Government is highly focusing on PHC as a new health care delivery model to improve access to service delivery for people living in rural and remote areas. Enhancing service access through innovative models of PHC helps to achieve the goal of health equity and affordable health care for all (Wakerman et al., 2008). Nurses play a critical role in dealing with the accessibility problem within the primary health care system. Their role has evolved due to changes in the health needs of the Australian communities due to ageing population. This caused additional pressure and demand on health care resource with problem in shortage of PHC workforce too. Nurses engage in integrated practice to reform the PHC health system (Nursing in primary health care, 2017).The main purpose of the essay is to comprehensively analyze the key principle of PHC and identify its relation with the role of geriatric nurse in these settings. Professional role of geriatric nurse Due to better standards of living and accessibility to high quality health care, life expectancy of people is increasing. The number of people above 65 years is increasing in Australia and it increased to 3.4 million in the year 2014 (AIHW, 2017). With the rise in ageing population, it will be a challenge for the health care system to respond to the health needs of older people. The geriatric care nurse in PHC setting plays a role in specially focusing on the health needs of older adults. They have the nursing skills and knowledge to understand the complex physical and mental health needs of older people in the community. Nurses involved in geriatric care works to promote independence of older people by caring for them and teaching them coping skills to manage mental and physical disabilities. Geriatric nurses in PHC receives the core competency training for older adult care and by their professional responsibility, they work to fulfill the core principles of PHC (Wold, 2013). As age ing population is a burden for the health care system and the community, the geriatric nurse establishes health equity by resolving the community problem related to ageing population. Principle of PHC The main principle of PHC is accessible health care, appropriate technology, health promotion, cultural sensitivity, intersectoral collaboration and community participation (Macdonald, 2013). This reflects that PHC provides a new approach to conceptualizing and planning health care. The role of each principle in relation to its positive health outcome and the contribution of the geriatric nurse in fulfilling it is explained in detail below: Accessible health care The first principle of PHC is to facilitate and implement strategy of equitable distribution of health services. This is achieved by providing equal access to health service to all people in the community. The four important components of accessible health care is appropriate coverage, services, timeliness and workforce. Improvement in all this area will facilitate timely use of health service. It will lead to increase in the quality of care and achievement of the best possible health outcome. The overall impact of access to health care is improvement in quality of life, life expectancy and physical, social and mental health status of people. This step has helped PHC to prevent disease by means of early diagnosis and treatment for health condition (Access to Health Services | Healthy People 2020, 2017). According to the principle of primary health care, gerontology nurse specialists have a role in care coordination and service-integration for at-risk older people. Therefore, the geriatric nurse works to specially provide adequate care to older people. A geriatric nurse working with older patients has the responsibility to assess mental and cognitive skills, identify chronic health issues, discuss risk to health such as incontinence or fall risk, manage their medications, educate them about personal safety and ensure adherence to treatment (Pierre Conley, 2017). In accordance with the PHCs principle of coordination, they also establishes link of patients with local resources to effectively manage their health care regimen and need of special equipment during care. Appropriate technology The second principle is related to the provisions of appropriate technology where PHC uses scientifically sound technologies to adapt to local needs. PHC achieves this by means of applying and using appropriate technology to respond to local needs of the community and extend the provision of essential technologies for health (Valentijn et al., 2013). Similar tools and technology is also available to geriatric nurses to conduct comprehensive health assessment of older people. In some case, ambulatory assessment is done to gain idea about quality of life activities and risk of fall in older patients. As fall is the leading cause of disability, multi-factorial interventions such as medication management, physical training, removal of fall risk factors around the environment of patients is necessary. Van Schooten et al., (2015) showed that fall-risk assessment done by means of Timed-Up and Go test or the Berg Balance Scale to evaluate gait dynamics of patients. By the use of these tools, nurses gathers information about gait characteristics of patients and eliminate fall-risk factor by modifying the environment and providing adequate support to patients at risk of fall. In many fall prevention interventions, physical activity is also encourages to maximize the capacity of geriatric client. Health promotion PHC is increasingly involved in decreasing the burden of chronic disease by means of health promotion and management strategies within health care system. WHO also recognizes the critical role of PHC centre in maintaining health of older people and increasing accessibility of health care to older population (Older people and Primary Health Care (PHC), 2017). Hence, in accordance with the goal of community health and development, geriatric nurses manage and negotiate within the health care delivery system to take care of geriatric clients. The solution to challenges in this area is proposed by means of collaborative teamwork approach. Kneafsey, Clifford and Greenfield, (2013) shows the nursing team involvement in promoting mobility of hospitalized older adults. As the ability to mobilize is an important determinant of the quality of life, targeting in-patient intervention to maintain mobility is important. In such condition, nursing team carry their responsibility in collaboration wit h physiotherapist and hospitals policy on safety of patients. This showed that rehabilitation goal of nurse mainly focus on preventing patient health problems and evaluating the effectiveness of the intervention. This is true to the PHCs requirement of health promotion within the community. Primary health care is increasingly advocating for older people. Their focus on this group of the community is seen because majority of older adults reside in countries that are not prepared to confront the challenges of ageing population. Although longevity reflects success of public health, however large proportion of older adults also increases the risk of more than one chronic disease in an individual (Older people and Primary Health Care (PHC), 2017). Hence, PHC tries to reduce this public health burden by recruitment of competent geriatric nurses in clinical setting. Cultural sensitivity According to the principle of cultural sensitivity, workforce of PHC is encouraged to bridge the gap in cultural barrier to health service. This is achieved by means of education on cultural beliefs and practices of culturally diverse people. The health care staffs attitude regarding respecting the cultural beliefs of patients in the delivery of care has a positive impact on patient health. PHC has worked to examine and address language and cultural barriers in care. Several cultural awareness program and language accessing services has been provided to encourage staff to deliver culturally appropriate care (Betancourt et al., 2016). Nurses provide culturally appropriate geriatric care by means of respecting patients cultural values and integrating nursing intervention with individual values and beliefs. Commitment to ongoing education regarding cultural values is essential to communicate with patients and peers. Secondly, intense introspection and reflection regarding cultural consideration is done by geriatric nurse to engage in transparent communication with patient. Cultural competence is also given special attention in health care policies. Hence, health care organization has made it necessary for gerentological nurse to understand and elicit the beliefs, attitudes and goals of older adults to provide culturally appropriate care (Role- Gerontological Rehab Nurse | role, 2017). Intersectoral collaboration The fifth principle according to the Alma-Ata declaration is that PHC is involved in coordination and cooperation with other sectors of community development such as agriculture, food, education and housing. Geriatric nurses integrate the knowledge and experience in gerontology to deliver safe and effective quality care to patients in PHC setting. It is the professional responsibility of geriatric nurses to conduct assessment to examine the health status of geriatric clients. Common form of assessment includes physical assessment of head, neck, face, integumentary system and musco-skeletal system. Secondly, fall risk assessment is an important part of assessment to assess risk of fall and level of independence in ADLs (activities of daily living). This form of comprehensive geriatric assessment also helps to identify frailty index in people to estimate risk of death and need for support during mobility and ADLs (Partridge et al., 2014). Based on this assessment, nurses develop an effective care plan for older adults and direct them to different support services. This professional action of geriatric nurses reflects their role in inter-sectoral coordination to promote community health and development. Community participation Finally, community participation is essential as overall PHC coverage will not be achieved unless the community is involved in planning and maintenance of health care. While working in primary care setting, geriatric nurse demonstrate competence in their role by means of reflecting on the care process and understanding the recent trends in ageing. This promotes advocacy in care by following professional standards in care and delivering ethically safe care (Naylor Kurtzman, 2010). Hence, as disability is a major problem in older adults, geriatric nurse works to promote mobility in older people to address the challenges of the ageing population. As part of universal health coverage, intervention promotes mobility in community dwelling older adults and improve their quality of living. 60% of hospital admission is for adults above 65 years of age. Hospitalized patients are mostly have negative outcome such as falls, delirium, mobility dependence and loss in ADLs. Nurses play a vital role in promoting their ability to walk by incorporating ambulation as a priority in the standards of care. They consider various factors while planning ambulation for older patients. Some of the factors influencing their decision-making on level of mobilization for individual patients includes purpose of mobilization, risk/ opportunity assessment and hospital trajectory (Doherty-King Bowers, 2011). Hence, their main intention is to promote complications in older adults at all time and through their professional responsibility, they contribute to fulfilling the objectives of PHC. From the analysis of the professional role of geriatric nurse, it is understood that they also play a critical role in promoting health equity and positive health of the community. Their professional responsibility in accordance with the principle of PHC helps to promote health and well-being of the older population. They contribute to reducing the burden of health care by identifying and treating chronic diseases in older patients and providing multi-factorial intervention to promote health and well-being of the ageing population.

Lord Capulet free essay sample

Romeo and Juliet, a play about two love birds from disputing families. Lord Capulet wants to give the impression of a man with much honor and peace; however when away from the public, Capulet is a fairly complicated individual. At the start, he gives the impression of a caring, considerate and loving father while discussing marriage with Paris; as well as a man of peace excusing the uninvited guest, Romeo. Though in Act III scene V, the audience witnesses the ugly side of Lord Capulet. When Juliet interfered with the â€Å"plans† of her father by disobeying his wishes, he became enraged. It wasn’t until Act IV, that Lord Capulet somewhat went back to his caring personality due to the â€Å"death† of his daughter. Confronted by the true death of Juliet, he let go of his foul ways and ended their family rivalry. The situations that occurred sprouted from the actions of characters trying to fulfill their wishes and others trying to fulfill theirs as well. We will write a custom essay sample on Lord Capulet or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Lord Capulet’s personality got in the way of numerous attempts, which created tension that would come back to haunt him. Lord Capulet, the head of the Capulet family whose intention throughout the play was to make both his family and himself look good in the eyes of others. He wanted to seem like a peaceful and loving man for the sake of his name. When we first see Lord Capulet, Act I scene I, he is calling to his wife to give him his sword. â€Å"Give me my long sword, ho! † (1. 1. 65) This can be seen as a very immature response to a situation as that for such an old man. Yet, when Capulet was discussing marriage with Paris, he seemed rational and mature. Juliet drifted from obeying traditional morals that other people of her time followed. That’s why Juliet, knowing the obsession her father had with image and that she was disobeying, hid her relations with Romeo. Lord Capulet saw Juliet as a pawn in his game for their success, however when she didn’t play accordingly to his rules, he lost it. After Juliet declined the offer of marriage with Paris, Capulet went in rage. â€Å"Unworthy as she is, that we have wrought so worthy, a gentleman to be her bride? † (3. 5. 144-145) â€Å"Out, you green sickness, carrion! Our, you baggage! You tallow face! † (3. 5. 56-158) Note, earlier in the play, when Juliet was an obedient daughter and followed traditions, he showed consideration of her thoughts and cared about her future. He said, â€Å"My child is yet a stranger in the world. † (1. 2. 8) â€Å"And too soon marred are those so early made†¦ An she agreed within her scope of choice, lies my consent and fair according voice. † (1. 2. 13,18-19) After her apology, Lord Capulet was pleased and changed the wedding date once again. For that, Juliet was forced to drink the elixir early, creating a scene. After Juliets â€Å"death†, sorrow is Capulets dominant reaction. Yet his sadness seemed to be stained with the thought that he will die without heirs and that the wedding is spoiled. It’s only when he sees Juliet in the tomb bleeding and dead does his sorrow over her loss and over his role in the feud seem complete. â€Å"O brother Montague, give me thy hand. † (5. 3. 13) â€Å"As rich shall Romeo’s by his lady’s lie, poor sacrifices of our enmity. † (5. 3. 19-20) Juliet’s doings tainted old Capulet’s temper, but so did the death of Tybalt. Tybalt Capulet, the nephew of the famed Lord Capulet who acted as the protector of the Capulet’s good name. Every scene incorporating Tybalt, included dueling and tension. He was always looking for a duel. When Tybalt and Mercutio fought and Mercutio was killed, it created a domino. Romeo killed Tybalt after the fact, Romeo was banished which made Juliet sad, and Lord Capulet felt as if he was under pressure because of the incident. He appears to be more concerned about how the marriage may affect the townspeople’s views on the seriousness or relaxed of his grieving for Tybalt. â€Å"For, hark you, Tybalt being slain so late, it may be thought we held him carelessly, being our kinsman, if we revel much. Therefore we’ll have some half a dozen friends, and there an end. † (3. 4. 25-29) That’s why he assumed that he was doing Juliet a favor and that she would go along with it. â€Å"Sir Paris, I will make a desperate tender of my child’s love. I think she will be ruled in all respects by me. † (3. 4. 12-14) In real, Juliet didn’t want to, and voiced her opinions to her father, which showed an obvious change from Lord Capulet. Juliet was forced to speed up her plan, creating a catastrophe, all due to the foolish actions of Tybalt and the inaccurate assumptions of Lord Capulet. Although, Capulet didn’t intentionally mean to push her daughter to death, he only wanted the best for her. There were many reasons why Lord Capulet changed. Marriage, death, defiance, and drama; yet the primary reason for his behavior was his daughter. He didn’t want to rush Juliet into marriage because he honestly cared for her. â€Å"Let two more summers wither in their pride ere we may think her ripe to be a bride. † (1. 2. 9-11) After Tybalt’s death, Capulet wanted to move the date of the wedding because he thought it would cheer up Juliet. That’s why he jumped to tell Paris, â€Å"Sir Paris, I will make a desperate tender of my child’s love. † (3. 4. 12-13) Later when Juliet rejected the marriage, Lord Capulet became angry because he wanted to leave a good legacy for his daughter, improving the family name, but she was ruining his plan. With Paris’s family, the Capulet would become richer and more popular. He only wanted his daughter to be secure and happy, but when she died nothing mattered anymore. â€Å"Alack, my child is dead, and with my child my joys are buried. †(4. 5. 4-65) Lord Capulet then made peace with his rivals for his Juliet. A leader wanting to be seen as a man of peace and honor, Lord Capulet had an image of just that, in the beginning. It wasn’t long until Capulet’s real appearance showed in his attempt to improve the family name. In the process, he showed bits of violent and rude traits, and lashed out on family. Between the marriage and Tybalt’s death, old Capulet was stressing both himself and his daughter out. Juliet was set as the family’s pawn in his plans. She was to be an obedient girl, follow with the morals of the time and marry Paris. Yet after Juliet found Romeo, she didn’t want to obey anymore, which set Capulet in rage. He only wanted what he thought was right for her, but she didn’t agree. Once Juliet died, we began to see that. Lord Capulet was working, throughout the play, on a foundation for Juliet to grow upon when he’s gone. He went through a ride of emotions in the development, from love and respect to anger and disrespect ending in sadness and shame. Although Capulet went through a range of changes, he ultimately did end the feud with his rivals, and that was a major change for old Lord Capulet.

Fed Corner Truncated Microstrip Patch Antenna

Fed Corner Truncated Microstrip Patch Antenna Ultra-Wide band communications attracted great interest of researchers as it has become one of the most promising technologies for short range mobile systems, Personal Area Networks (PAN) and high speed indoor data communication applications. FCC mentioned parameters for the complete functioning of UWB antennas and they have to cover the bandwidth specified by FCC to attain adequate performance. UWB has the advantage of high data rates with extremely low interference to other narrow band systems. The ultra short pulses provide extremely good spatial resolution, as the range provided by UWB is enough to seize down the major applications of daily life like in ground penetrating radars, parking radars, biomedical imaging, precision tracking and location finding. Various types of UWB antennas have been proposed and implemented with different feeding techniques, such as transmission line, probe feed, dual feed and coplanar waveguides (CPW). A compact antenna design fed by coplanar waveguide (CPW) is proposed. Overall dimensions of antenna are 28ÃÆ'-24 mm2. The design is fabricated and further analyzed to confirm its proper working in UWB range. The design of antenna is quite flexible as fiddling with the patch of microstrip antenna has been done in order to enhance the bandwidth which is the most valued obsession in the current environment. On the other hand, CPW has many advantages such as low radiation leakage, less dispersion at higher frequency, small mutual coupling between two adjacent lines which is helpful to place circuit elements close together without adding an additional layer of substrate and coplanar capability. Using CPW as feeding structure to excite a patch antenna has become very popular recently. The proposed antenna offers an excellent performance for UWB systems by providing bandwidth ranging up to 15.65GHz. Critical design parameters return loss and radiation patterns are investigated in detail. Proposed antenna provides good impedance matching, stable gain characteristics and consistent radiation patterns over its almost whole frequency band of interest. Chapter 1 Introduction Project Overview IEEE defines antenna as a device for radiating and receiving electromagnetic waves. They are used both as transmitter and receiver. This is era of wireless communication. Antennas are an important means of wireless communications now days. The need of time is compact small size antennas with enhanced bandwidth and gain. Amongst all antenna types microstrip patch antennas are most common. They are light in weight and consume low power. But patch antennas have disadvantage that they have narrow bandwidth. Many techniques are used to enhance bandwidth. Ultrawide band antennas have many applications and for many years they have been used for broadband and spread spectrum features in radar systems. The UWB performances of antennas result from excitation by non-sinusoidal signals with quickly time-varying performances [1]. UWB are low power consumption antennas and are for unlicensed applications. As name suggests, they have broad spectrum. Problem Statement Ultra wideband technology is used in low power, short range and high bandwidth communication. In UWB; through spreading information can be transmitted over a larger bandwidth and spectrum is also shared with the other users at the same time. Federal Communication Commission (FCC) allocated the license free band of 3.1GHz-10.6GHz for use in UWB applications. Since then there is a growing demand of UWB antennas for high data rate applications i.e. wireless personal area network (WPAN). UWB has had a important effect on antenna design. The major challenge in UWB antenna design is to achieve wide impedance bandwidth and stable gain while maintaining high radiation efficiency. Project Objective The purpose of this project is to design, stimulate, analyze and fabricate ultra wide band antenna using co-planer waveguide. Design and analysis of a compact antenna fed by CPW for UWB Applications is proposed Bandwidth of the proposed antenna is 15.65 GHz. Antenna offers an excellent performance for ultra-wide band systems by providing an ultra-wide bandwidth ranging from 3.1 18.75 GHz. Gain of the proposed antenna is 4.91dBi over its almost whole frequency band of interest Small size of antenna makes it suitable for applications which demand miniaturization of antenna structure and input impedance of 50 à ¢Ã¢â‚¬Å¾Ã‚ ¦. Methodology We have simulated the designed antenna using Ansoft HFSS. Then the simulated antenna is fabricated and tested on the network analyzer. The simulated and measured results are also explained. Organization of the thesis This report is divided into 6 chapters. Chapter 2 presents the fundamental parameters of antenna. This includes an explanation of various parameters related to antenna performance including radiation intensity ,radiation pattern, power density , gain, directivity and polarization etc. Chapter 3 discusses the Microstrip Patch Antenna and Feeding techniques. Chapter 4 includes Ultra wide band microstrip patch antenna, history of UWB antennas, their features and advantages. Chapter 5 describes antenna design, simulated results, 2D and 3D radiation patterns for different frequencies and fabricated results. Chapter 6 concludes the entire work done throughout the designing of proposed antenna. Conclusion and future work helps to explore enormity of the subject. Chapter 2 Fundamental Parameters of Antenna 2.1 Radiation Pattern The radiation pattern describes the strength of the radiated field in different directions from the antenna, at a constant distance. The radiation pattern is also reception pattern, as it describes the receiving properties of the antenna. It is defined as a mathematical function or a graphical representation of the radiation properties of antenna as a function of space coordinates. In most cases the radiation pattern is determined in far field regions and is defined as a function of the directional coordinates. Radiation properties include power flux density, radiation intensity, field strength, directivity phase or polarization [2]. The radiation pattern is three-dimensional, but measured patterns are usually two dimensional in vertical or horizontal plane view. These measured patterns are presented in either rectangular or polar format. Following figure shows radiation pattern of an antenna in polar plane and Cartesian coordinate systems. http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/images/0900aecd806a1a3e_null_null_null_08_07_07-03.jpg Figure-2.1: Radiation Pattern of an antenna in Cartesian and polar coordinates Radiation patterns are further categorized as relative and absolute radiation patterns. Absolute radiation patterns have absolute units of power or field strength. Relative radiation patterns are presented in relative units of power or field strength. The radiation measurement patterns are mostly relative to isotropic antennas, absolute gain of the antenna is established by antenna gain transfer method. The radiation pattern varies with the distance i.e. the patterns in near filed and far filed are different. The field pattern that exists close to the antenna is known as near filed, and far-field refers to the field pattern that exists at large distances. The far-field is called radiation field. Radiation field and power are what is commonly of interest, so antenna patterns are generally measured in the far-field region. For antenna pattern measurement the distance should be chose large enough not to be in near-field or in far field. The minimum allowed distance depends on the dimensions of the antenna relative to the wavelength. The formula for this distance is: rmin = 2d2/ÃŽÂ » (2.1) Where, rmin is the minimum distance from the antenna d is the largest dimension of the antenna ÃŽÂ » is the wavelength. 2.1.1 Radiation Pattern Lobes Radiation lobes are defines as portion of radiation pattern bounded by regions of relatively weak radiation intensity [3]. These lobes are categorized as follow Major Lobes Minor Lobes Side Lobes Back Lobes 2.1.2 Major Lobe A major lobe is defined as the radiation lobe containing the direction of maximum radiation [2]. Normally an antenna has one major lobe. 2.1.3 Minor Lobe Any lobe except major lobe is called minor lobe. It usually represents the radiation pattern which is not desirable. 2.1.4 Side Lobe A side lobe is a radiation lobe in any direction other than the main lobe [2]. Usually a side lobe is next to the main lobe and is in direction to the main lobe. 2.1.5 Back Lobe A back lobe is a radiation lobe whose axis makes an angle of approximately 180 ° with respect to the beam of an antenna or that is directed away from the main lobe [2]. File:Typical Antenna Pattern.jpg Figure 2.2: An illustration of major and minor lobes of radiation pattern 2.2 Field Regions The antenna fields are divided into three regions Reactive near field Radiating near field (Fresnel) Far field (Fraunhofer) http://www.nearfield.com/images/theory-ffdist.jpg Figure 2.3: Figure of Near Field and Far Field Regions 2.2.1 Reactive Near Filed It is the region immediately around the antenna. In this region the reactive filed predominates. The distance of this filed with antenna is usually R 2.2.2 Radiating Near Field (Fresnel) Radiating near filed is defines as that region of the field of an antenna between the reactive near-filed and the far-filed region wherein radiation fields predominate and wherein the angular field distribution is dependent upon the distance from the antenna [2]. The distance of inner boundary is R 2.2.3 Far Field Region (Fraunhofer) Far Field region is defined as that region of the field of an antenna where the angular filed distribution is essentially independent of the distance from the antenna [2]. 2.3 Radiation Intensity Radiation Intensity is the power radiated from an antenna per unit solid angle. It is the parameter of far field radiation. 2.4 Directivity Directivity is figure of merit for antennas. It is the power density an antenna radiates in direction of maximum radiation to the average power density radiated by an isotropic antenna. Directivity for an isotropic antenna is always unity. It is expressed as D= (2.2a) (2.2b) Where, D is directivity and U is radiation intensity, Uo is Intensity if an isotropic source and Prad is total radiation power. 2.5 Gain The gain and directivity of an antenna are closely related to each other. However for gain in denominator it is total power accepted by an antenna rather than total power radiated by an antenna. G= (2.3) Gain is dimensionless. According to IEEE standards, gain doesnt include losses arising from impedance mismatching or polarization mismatches. 2.6 Bandwidth The bandwidth is basically the difference or range between highest and lowest frequencies on which an antenna is operated. It is advantageous to have an antenna with high bandwidth. The bandwidth is expressed in term of ratio of upper cut off to the lower cutoff for broadband antennas. 2.7 Beamwidth Beamwidth is the angle usually measured in degrees; between the -3dB power radiated in the main lobe of radiation pattern. img383 Figure 2.4: Illustration of Beamwidth 2.8 Return Loss It is the amount of power that is reflected back in to the transmission line due to mismatching or any other error. It is the efficiency of power delivered to the load from the transmission line. Mathematical representation of Return loss is RL = 10log (2.4) Return loss is measured in dB. http://www.mwrf.com/Files/30/11240/Figure_05.gif Figure 2.5: Return Loss 2.9 Polarization Polarization is defined as point of reference of the electric field of the wave radiated by the antenna. It is categorized in three types: Linear Circular Elliptical 2.9.1 Linear Polarization When there is zero phase difference between x and y component of a wave then polarization is called linear polarization. Linear polarization is further divided into Horizontal polarization Vertical polarization http://www.ccrs.nrcan.gc.ca/glossary/images/3104.gif Figure 2.6: Linear Polarization 2.9.1.1 Horizontal Polarization Horizontal polarization is the one in which wave propagates in x-direction and there is no propagation along y direction. A horizontally polarized wave is explained as a function of time T and E-field position Ex = E1 sin ( É ·t à ¡Ã‚ µÃ‚ z) (2.5) http://www.cfht.hawaii.edu/~manset/PolHoriz.gif Figure 2.7: Horizontal Polarization 2.9.1.2 Vertical Polarization Vertical polarization is the one in which wave propagates in y-direction and there is no propagation along x direction. It can be written in mathematical form as Ey = E2 sin ( É ·t à ¡Ã‚ µÃ‚ z) (2.6) http://www.cfht.hawaii.edu/~manset/PolVert.gif Figure 2.8: Vertical Polarization 2.9.2 Circular Polarization If there is equal phase difference between two waves then there is circular polarization, either clockwise or anticlockwise. Wave moving in clockwise rotation is said to be left circularly polarized and the one propagating in counterclockwise rotation is right circularly polarized. Mathematically it is defined as Ex = E1 sin (É ·t à ¡Ã‚ µÃ‚ z) (2.7) Ey = E2 sin (É ·t à ¡Ã‚ µÃ‚ z + ÃŽÂ ´) (2.8) E1 is the amplitude of wave linearly polarized in x direction. E2 is the amplitude of wave linearly polarized in y direction. ÃŽÂ ´ is the phase difference. http://www.cfht.hawaii.edu/~manset/PolCirc.gif Figure 2.9: Circular Polarization 2.9.3 Elliptical Polarization If two waves have unequal amplitude or phase then there is elliptical polarization. graphic 1 Figure 2.10 (a): Graphical Representation of Elliptical Polarization http://www.nsm.buffalo.edu/~jochena/images/elliptic2.gif Figure 2.10 (b): 3-D view of Elliptical Polarization 2.10 Voltage Standing Ratio VSWR is the ratio between maximum voltage and the minimum voltage. If there is a difference between load impedance and input impedance then there occurs reflection which causes instructive interference and destructive interference. Instructive and destructive interference produces maximum and minimum amplitudes respectively. Mathematical Expression for VSWR is VSWR= (2.9) http://www.microwaves101.com/encyclopedia/images/VSWR/waves5.jpg Figure 2.11: Different Voltage amplitudes at different distances 2.11 Types of antennas There are six different types of antennas [2]. Microstrip Patch Antenna Lens Antenna Wire Antenna Array Antenna Reflector Antenna Aperture Antenna 2.11.1 Microstrip Patch Antenna Microstrip patch antennas fall into the category of printed antennas [4]. A radiating patch is printed on a grounded substrate which is usually feed via a transmission line or coaxial cable. Patch can be of any shape and size i.e. circular, square, triangular or rectangular. Amongst all printed antennas i.e. Dipole, Slots, Tapered Slots antennas; Microstrip Patch Antennas are most famous. They are small in size, light in weight and low power consuming. But their bandwidths are smaller and have low gain. They are easy to integrate, good radiation control and cost of production is low. To increase bandwidth many techniques are used that is introducing slots and slits etc. They are used commercially in radars, wireless communications, satellites and mobiles etc. Figure 2.12: Microstrip patch Antenna http://images.books24x7.com/bookimages/id_22121/fig188_01.jpg Figure 2.13 (a): Rectangular Patch Antenna (b): Circular Patch Antenna Microstrip Patch antennas are used in Microwave frequency range. They are used in arrays to increase the bandwidth and gain and for other purposes. http://www.antennamagus.com/database/antennas/99/Stacked_microstrip_patch_array-antenna_design.png Figure 2.14: Array of rectangular patch antennas 2.11.2 Lens Antenna Lens antennas are used to convert spherical radiated waves into plane waves in specific direction by using a source with microwave lens. It actually stops the divergent radiated energy to spread in undesired directions. These are mostly used for the high frequencies. A lens antenna may be of concave or convex shape. They are directional antennas and can scan wider angles. In comparison to reflectors; their gain is 1 or 2 dB less. Lens antennas may be constructed of non-metallic dielectrics or of metallic (artificial) dielectrics [5]. http://www.xibao-electronictech.com/images/product/2/210Lens-Antenna.gifhttp://telecom.esa.int/telecom/media/img/largeimage/WaveguideLensAntennaPrjObj_404.jpg Figure 2.15 (a): Lens Antenna Figure 2.15 (b): Wave guide Lens Antenna 2.11.3 Wire Antenna Wire antennas consist of a simple wire that is used to radiate electromagnetic energy. These wire antennas can be of different shapes. Most commonly used are straight wire antennas i.e. dipoles, loops and helix. Beside half-wave dipoles and quarter wave monopoles, wires of arbitrary lengths are often used to form antennas. Wire antennas can be vertical, horizontal or sloppy with respect to the ground. They may be fed from centre, at end or anywhere in between. The wires can be thick or thin, the radiation of antenna depends upon the thickness of the wire. Antennas with length larger than ÃŽÂ »/2 are called Long-wire antennas. Figure 2.16 (a): Wire Antennas (a) Figure 2.16 (b): Dipole Circular loop 2.11.4 Array Antenna Array antennas are made up of more than one element basic of which is a dipole. Array antennas are the combination of radiating elements in such way that the radiation from these add up giving maximum or minimum radiation in a specific direction. They are used for higher directivity. They are made up of helices, dishes and other antennas. These elements are arranged to form broadside, end fire, collinear, driven and patristic arrays [5]. They are used in applications in which radiation cannot be achieved from single radiating element. They are low weight and low cost antennas. Examples of array antennas are Yagi-Uda, http://www.tennadyne.com/images/tennlpdanavy.JPG Figure 2.17: Log Periodic Dipole Array Antenna 2.11.5 Reflector Antenna They are widely used to modify the radiation pattern of radiating elements. They are classified as active and passive reflectors. The active reflectors have corners made up of plane surfaces and they include periscopic antennas, flat-sheet reflectors and corner-reflector antennas. An active reflector may have corner elliptical, parabolic or spherical shape. Active reflectors include parabolic dish, truncated parabola, pill box etc. Reflectors are simple in design, involve only one surface and obey simple laws of optics. The applications of reflector antennas are radars and other point to point communication systems [5]. http://www.sameercal.org/images/reflector_antenna.jpg Figure 2.18: A co-secant Reflector Antenna 2.11.6 Aperture Antenna Aperture antenna is an important antenna for space communication. As the name suggests they consist of some cavity through which electromagnetic waves are transmitted or received. Apertures may be of any shape i.e. rectangular, circular or spherical. Larger the size of antenna larger will be the gain. Aperture antennas have to be placed carefully because they have narrow beam widths. Examples of aperture antennas include waveguides, reflectors horns, slots and lenses. Aperture antennas are commonly used in aircraft and spacecraft applications. http://www.analyzemath.com/antenna_tutorials/introduction_3.gif Figure 2.18: Horn Aperture Antenna Chapter 3 Microstrip Patch Antenna and Feeding techniques 3.1 Introduction Spaceships, aircrafts and other military applications such as missiles where important constraints to consider are performance, manufacturing expenditures, smooth profile and ease of installation and now a days other systems such as wireless communication requires similar type of specifications to consider . And the basic component which is required by these listed applications for transmission of instructions or data and to receive these instructions on the receiver end is antenna. Hence to meet the requirements listed above e.g. smooth profile, cost and performance etc Microstrip antennas are used. Microstrip antennas are diminutive profile, conformable to planar and non-planar surfaces, easy and cheap to construct using the up to date printed circuit technology. Microstrip antennas have very flexible behavior to polarization, resonant-frequency, and impedance and radiation pattern. They are also used to increase the bandwidth. They consist of a ground plane over which a substrate is mounted and the radiating patch is mounted on the substrate. Generally the ground plane and the dielectric substrate have equal length and width. The Microstrip antennas are illustrated by the width, length and the height of the dielectric substrate which is sandwiched in between the ground plane and the radiating patch 3.2 Structural Configuration The structural configuration of micro strip patch antenna is shown in figure Figure 3.1: Structural Configuration of Patch Antenna It consist of a thin (t Figure 3.2: Side View of Patch Antenna The length of the patch is usually ÃŽÂ »/3 3.3 Formula for Rectangular Patch Antenna To draw the width of the patch we use the formula (3.1) And the length of the patch can be drawn as: (3.2) To reduce the fringing effects we use the following formula à ¢Ã‹â€ Ã¢â‚¬  L= 0.412h (3.3) Here à ¢Ã‹â€ Ã¢â‚¬  L is the trimmed length from antenna. (3.4) 3.4 Feeding Methods Following feeding methods are most popular and are used with microstrip antennas 1. Microstrip line feed 2. Coaxial probe feed 3. Aperture coupled feed 4. Proximity coupled feed 5. Coplanar waveguide feed These methods are either contacting or non-contacting. Contacting methods are those in which there is a direct contact between the transmission line and the radiating surface whereas in non-contacting methods, electromagnetic field coupling method is used to transfer the power. 3.4.1 Microstrip Line Feed In this feeding method, the line feed is conducting strip of small width as compared to the patch. It is the easiest feeding method; easy to fabricate and simple to model. The radiating strip is placed at radiating patchs edge and it is of the same material that is used for patch. If length of the strip is greater than the wavelength, losses will be generated. It can be reduced if the strip line has a substrate with high dielectric constant and low weight, so that the fields are confined to the strip line. A line feed of dimensions 17x3mm is used to obtain 50ÃŽÂ © input resistance. Figure 3.1: Patch with Microstrip Line Feed 3.4.2 Coaxial probe feed In coaxial probe feeds, coax inner conductor is attached to the radiating patch while the other conductor is connected to the ground plane. It is used widely. Its fabrication is easy and has low spurious radiation that is radiation outside the band frequency. It is has narrow bandwidth and it is hard to model for thick substrate. Matching also becomes difficult for thicker substrate because of increase length of probe make it more inductive, its inductance effect can be reduced by using a series of capacitors. Figure 3.2: Patch with coaxial probe feed 3.4.3 Aperture coupling feed It is the non-contacting feed. The two substrates are separated by ground plane in it. The microstrip feed line is on the bottom side of the lower substrate there is a; whose energy is coupled to the patch through a slot on the ground plane which separates the two substrates. A material with higher dielectricity is used for bottom substrate therefore, by this arrangement independent optimization of the feed mechanism and the radiating element can be carried out. For top substrate a thick, low dielectric constant material is used. The ground plane between the two substrates isolates the feed from the radiating element and minimizes the interference. The configuration is shown in the figure Figure 3.3: Patch with aperture coupling feed Matching is performed by controlling the width of the feed line and the length of the slot. Amongst all four techniques this is the hardest to fabricate and has narrow bandwidth. It is somehow easy to model and has moderate spurious radiation. 3.4.4 Proximity coupling feed In this feeding method, microstrip line is placed between two substrates and the radiating patch is placed on the upper substrate. This coupling is capacitive in nature. This coupling has the largest bandwidth as high as 13%. It is easy to model and has low spurious radiation. Its fabrication is somehow difficult. However, length of the stub help in improving the bandwidth, and width-to-line ratio of the patch can be used to control the match. The coupling feed is shown Figure 3.4: Patch with Proximity Coupling Feed 3.4.5 Coplanar Waveguide Feed This feeding technique is used when patch antenna is used in microwave monolithic integrated circuits (MMIC). The coplanar feed is fabricated on a ground plane and coupling is achieved through a slot. This feeding method reduces the radiation from feed structure because of its unusual method of coupled slot. Since CPW (coplanar waveguide) has many advantages such as low radiation leakage, less dispersion and small mutual coupling between two adjacent lines, which is helpful to place circuit elements close together without adding an additional layer of substrate, using CPW as the feeding structure to excite the patch antenna through a slot has become very popular recently. In addition, CPW structure can maintain constant characteristic impedance while varying its geometry, which provides a better impedance matching possibility Figure 3.5: Patch with Coplanar Waveguide Feed 3.3 Categorization on the basis of bandwidth:- On the basis of range of frequency bands, microstrip patch antennas can be categorized into three main classes which are: antenna for narrow band applications antenna for wide band applications antenna for ultra wideband applications Chapter 4 ULTRA WIDEBAND 4.1 Introduction A series of very short baseband pulses with time duration in nano-seconds that exist on ALL frequencies simultaneously. Pulse repetition frequency (PRF) can range from hundreds of thousands to billions of pulses/second. Very low power: 41dbm/MHz (FCC) and wide bandwidth: 3.110.6 GHz Modulation techniques include pulse-position modulation binary phase-shift keying And others Radio technology that modulates impulse based waveforms instead of continuous carrier waves 4.1.1 Narrow band vs. Wide band signals UWB could be used to Indoor, short-range communications for high data rates, OR Outdoor, long-range, but for very low data rates 4.1.2 Large Relative Bandwidth UWB is a form of extremely wide spread spectrum where RF energy is spread over gigahertz of spectrum. Wider than any narrowband system by orders of magnitude. Power seen by a narrowband system is a fraction of the total.UWB signals can be designed to look like imperceptible random noise to conventional radios 4.1.3 Large Fractional Bandwidth Large fractional bandwidth leads to High processing gain and Multipath resolution and low signal fading. Fractional Bandwidth is the ratio of signal bandwidth (10 dB) to center frequency: Bf = B / FC = 2(Fh-Fl) / (Fh+Fl) 4.1.4 Scalable Technology with Low Power UWB benefits from basic information theory results when: Signal Bandwidth >> Data Rate .Power efficient low-order modulation can be used even for relatively high data rates.Data rates can scale independent of PRF by integrating bit intervals over multiple pulse intervals 4.1.5 Multipath Performance Ultra-wide bandwidth provides robust performance in multipath environments . 4.1.6 UWB Data Rates 4.2 UWB channels Indoor Within a room (LOS NLOS) Investigates the impact of Distance Rx/Tx antenna heights Antenna polarization C:mat_dirsuwblimitsindoor5.tif UWB Emission Limit for Indoor Systems Outdoor Campus environment Low altitude Mobility C:mat_dirsuwblimitsoutdoor5.tif UWB Emission Limit for Outdoor Hand-held Systems 4.3 Emission limits for UWB UWB Emission Limits for GPRs, Wall Imaging, Medical Imaging Systems.
