## Antenna Theory: Analysis and Design

The fourth edition of Antenna Theory is designed to meet the needs of electrical engineering and physics students at the senior undergraduate and beginning graduate levels, and those of practicing engineers. Mathematical techniques required for understanding some advanced topics in the later chapters are incorporated in the individual chapters or are included as appendices.

The book, since its first edition in and subsequent two editions in and , has been a pacesetter and trail blazer in updating the contents to keep abreast with advancements in antenna technology. This has been accomplished by:. While incorporating the above new topics and features in the current edition, the book maintained all of the attractive features of the first three additions, especially the:.

Three-dimensional graphs to display the radiation characteristics of antennas. This feature was hailed, at the time of its introduction, as innovative and first of its kind addition in a textbook on antennas.

Because there are so many methods of analysis and design and a plethora of antenna structures, applications are made to some of the most basic and practical configurations, such as linear dipoles; loops; arrays; broadband, and frequency-independent antennas; aperture antennas; horn antennas; microstrip antennas; and reflector antennas.

A tutorial chapter on Smart Antennas is included to introduce the student to a technology that will advance antenna theory and design, and revolutionize wireless communications. It is based on antenna theory, digital signal processing, networks, and communications. MATLAB simulation software has also been included, as well as a plethora of references for additional reading. Introductory material on analytical methods, such as the Moment Method and Fourier transform spectral technique, is also included.

These techniques, together with the fundamental principles of antenna theory, can be used to analyze and design almost any antenna configuration. A chapter on antenna measurements introduces state-of-the-art methods used in the measurements of the most basic antenna characteristics pattern, gain, directivity, radiation efficiency, impedance, current, and polarization and updates progress made in antenna instrumentation, antenna range design, and scale modeling.

Techniques and systems used in near- to far-field measurements and transformations are also discussed. A sufficient number of topics have been covered, some for the first time in an undergraduate text, so that the book will serve not only as a text but also as a reference for the practicing and design engineer and even the amateur radio buff.

These include design procedures, and associated computer programs, for Yagi—Uda and log-periodic arrays, horns, and microstrip patches; synthesis techniques using the Schelkunoff, Fourier transform, Woodward—Lawson,.

Tschebyscheff, and Taylor methods; radiation characteristics of corrugated, aperture-matched, and multimode horns; analysis and design of rectangular and circular microstrip patches; and matching techniques such as the binomial and Tschebyscheff.

Chapter 14 has been expanded to include antennas for Mobile Communications. These are popular internal antennas for mobile devices smartphones, laptops, pads, tablets, etc. Hybrid modes are used to analyze and determine the resonant frequencies and quality factor Q of the Cylindrical DRA.

A detailed procedure to follow the design is outlined in Section A certain amount of analytical detail, rigor, and thoroughness allows many of the topics to be traced to their origin. Each chapter is subdivided into sections or subsections whose individual headings clearly identify the antenna characteristic s discussed, examined, or illustrated.

A distinguished feature of this book is its three-dimensional graphical illustrations from the first edition, which have been expanded and supplemented in the second, third and fourth editions. In the past, antenna texts have displayed the three-dimensional energy radiated by an antenna by a number of separate two-dimensional patterns.

With the advent and revolutionary advances in digital computations and graphical displays, an additional dimension has been introduced for the first time in an undergraduate antenna text by displaying the radiated energy of a given radiator by a single three-dimensional graphical illustration.

Such an image, formed by the graphical capabilities of the computer and available at most computational facilities, gives a clear view of the energy radiated in all space surrounding the antenna. In this fourth edition, almost all of the three-dimensional amplitude radiation patterns, along with many two-dimensional graphs, are depicted in color and gray-scale. This is a new and pacesetting feature adopted, on a large scale, in this edition.

It is hoped that this will lead to a better understanding of the underlying principles of radiation and provide a clearer visualization of the pattern formation in all space. In addition, there is an abundance of general graphical illustrations, design data, references, and an expanded list of end-of-the chapter problems. Many of the principles are illustrated with examples, graphical illustrations, and physical arguments. Although students are often convinced that they understand the principles, difficulties arise when they attempt to use them.

An example, especially a graphical illustration, can often better illuminate those principles. Each program is interactive and prompts the user to enter the data in a sequential manner. However, many new ones have been developed. The computer programs can be used for analysis and design.

Some of them are more of the design type while some of the others are of the analysis type. The purpose of the Power Point Lecture Notes is to provide the instructors a copy of the text figures and some of the most important equations of each chapter.

They can be used by the instructors in their lectures but may be supplemented with additional narratives. Each instructor will use the notes in a different way. The Interactive Questionnaires are intended as reviews of the material in each chapter.

The student can use them to review for tests, exams, and so on. For each question, there are three possible answers, but only one is correct. If the reader chooses one of them and it the correct answer, it will so indicate.

However, if the chosen answer is the wrong one, the program will automatically indicate the correct answer. An explanation button is provided, which gives a short narrative on the correct answer or indicates where in the book the correct answer can be found. The Animations can be used to illustrate some of the radiation characteristics, such as amplitude patterns, of some antenna types, like line sources, dipoles, loops, arrays, and horns.

The Applets cover more chapters and can be used to examine some of the radiation characteristics such as amplitude patterns, impedance, bandwidth, etc. For course use, the text is intended primarily for a two-semester or two- or three-quarter sequence in antenna theory. The first course should be given at the senior undergraduate level, and should cover most of the material in Chapters 1 through 7, and some sections of Chapters 14, 16 and The material in Chapters 8 through 16 should be covered in detail in a beginning graduate-level course.

Selected chapters and sections from the book can be covered in a single semester, without loss of continuity. However, it is essential that most of the material in Chapters 2 through 6 be covered in the first course and before proceeding to any more advanced topics. To cover all the material of the text in the proposed time frame would be, in some cases, an ambitious and challenging task.

Sufficient topics have been included, however, to make the text complete and to give the teacher the flexibility to emphasize, deemphasize, or omit sections or chapters.

Some of the chapters and sections can be omitted without loss of continuity. In some cases, the units of length are in meters or centimeters and in feet or inches. Numbers in parentheses refer to equations, whereas those in brackets [] refer to references. For emphasis, the most important equations, once they are derived, are boxed. In some of the basic chapters, the most important equations are summarized in tables. I will like to acknowledge the invaluable suggestions from all those that contributed to the first three additions of the book, too numerous to mention here.

Their names and contributions are stated in the respective editions. It is my pleasure to acknowledge the suggestions of the reviewers for the fourth edition: Dr.

Stuart A. Long of the University of Houston, Dr. Cynthia M. Furse of the University of Utah. There have been other contributors to this edition, and their contributions are valued and acknowledged. I am indebted to Dr. Alix Rivera-Albino who developed with special care all of the color and gray scale figures and illustrations for the fourth edition and contributed to the manuscript and figures for the Vivaldi and mobile antennas.

Это была шутка, Мидж.

Тихо, - потребовал Фонтейн и повернулся к Сьюзан.  - Мисс Флетчер, вы проделали уже немалую часть пути. Постарайтесь пройти по нему до конца. Сьюзан вздохнула: - Программа принимает ключ только в цифровой форме. Мне кажется, что тут содержится некий намек на то, что это за цифра.

- Что говорится в его посланиях на имя Танкадо. - Понятия не имею. КОМИНТ засек лишь исходящую почту. В данный момент мы ничего не знаем про Северную Дакоту, кроме анонимного адреса.
