This book was released on 2004-04-07 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-stop reference to the design and analysis of nonplanar microstrip structures. Owing to their conformal capability, nonplanar microstrip antennas and transmission lines have been intensely investigated over the past decade. Yet most of the accumulated research has been too scattered across the literature to be useful to scientists and engineers working on these curved structures. Now, antenna expert Kin-Lu Wong compiles and organizes the latest research results and other cutting-edge developments into an extensive survey of the characteristics of microstrip antennas mounted on canonical nonplanar surfaces. Demonstrating a variety of theoretical techniques and deducing the general characteristics of nonplanar microstrip antennas from calculated results, Wong thoroughly addresses the problems of cylindrical, spherical, and conical structures and gives readers powerful design and optimization tools. Up-to-date topics range from specific applications of spherical and conical microstrip arrays to the curvature effects on the analysis of cylindrical microstrip lines and coplanar waveguides. With 256 illustrations and an exhaustive list of references, Design of Nonplanar Microstrip Antennas and Transmission Lines is an indispensable guide for antenna designers in wireless and personal communications and in radar systems, and an invaluable reference for researchers and students interested in this important technology.

Available in PDF, EPUB and Kindle. Book excerpt: Arrays of cylindrical dipoles and monopoles are usually driven by means of interconnecting transmission lines, whereas analyses of such arrays are generally made in terms of currents or voltages with assigned relative amplitudes and phases at the individual input terminals. Moreover, it is commonly assumed that the distributions of current along all elements are the same and without phase variation. In this report the properties of broadside and endfire arrays are treated with full consideration of interconnecting transmission lines and the effect of mutual coupling on the distributions of current. Driving-point admittances and field patterns of arrays of half-wave and full-wave elements are given. A novel broadside-endfire array is described. (Author).

Download or read book Generalized Transmission Line Method to Study the Far zone Radiation of Antennas Under a Multilayer Structure written by Zuan Hui Wu and published by Springer Nature. This book was released on 2022-06-01 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a step-by-step presentation of a generalized transmission line method to study the far-zone radiation of antennas under a multilayer structure. Normally, a radiation problem requires a full wave analysis which may be time consuming. The beauty of the generalized transmission line method is that it transforms the radiation problem for a specific type of structure, say the multilayer structure excited by an antenna, into a circuit problem that can be efficiently analyzed. Using the Reciprocity Theorem and far-field approximation, the method computes the far-zone radiation due to a Hertzian dipole within a multilayer structure by solving an equivalent transmission line circuit. Since an antenna can be modeled as a set of Hertzian dipoles, the method could be used to predict the far-zone radiation of an antenna under a multilayer structure. The analytical expression for the far-zone field is derived for a structure with or without a polarizer. The procedure of obtaining the Hertzian dipole model that is required by the generalized transmission line method is also described. Several examples are given to demonstrate the capabilities, accuracy, and efficiency of this method.

Download or read book Radiating Nonuniform Transmission Line Systems and the Partial Element Equivalent Circuit Method written by Prof. Dr. Juergen Nitsch and published by John Wiley & Sons. This book was released on 2009-10-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: High frequencies of densely packed modern electronic equipment turn even the smallest piece of wire into a transmission line with signal retardation, dispersion, attenuation, and distortion. In electromagnetic environments with high-power microwave or ultra-wideband sources, transmission lines pick up noise currents generated by external electromagnetic fields. These are superimposed on essential signals, the lines acting not only as receiving antennas but radiating parts of the signal energy into the environment. This book is outstanding in its originality. While many textbooks rephrase that which has been written before, this book features: an accessible introduction to the fundamentals of electromagnetics; an explanation of the newest developments in transmission line theory, featuring the transmission line super theory developed by the authors; a unique exposition of the increasingly popular PEEC (partial element equivalent circuit) method, including recent research results. Both the Transmission Line Theory and the PEEC method are well suited to combine linear structures with circuit networks. For engineers, researchers, and graduate students, this text broadens insight into the basics of electrical engineering. It provides a deeper understanding of Maxwellian-circuit-like representations of multi-conductor transmission lines, justifies future research in this field.

Download or read book Antennas as Transmission Lines written by John Lenahan and published by . This book was released on 2022-06-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antennas as Transmission Lines: Linear Antenna Analysis and Design Requiring Only Algebra and Trigonometry The models presented in this book treat antennas as transmission lines. The antenna as transmission line models in this book will help you learn about antennas in a way that does not require advanced mathematics. The chapters are arranged in sections to apply transmission line models to examples of real life antennas, which are then compared to computer software models. Some examples in this book are validated by measurement of full size physical models. Treating linear antennas as transmission lines, using trig and log functions, with some Algebra, makes it possible to calculate circuit models of feed point impedance as would be measured with an antenna analyzer or VNA (vector network analyzer). Through the use of the transmission line model, linear antennas in this book are reduced to basic AC circuit components - resistors, inductors and capacitors. The insight into antennas from using transmission line models can transform your ability to visualize, analyze and synthesize antennas to your benefit. Over the years of using and teaching this method my understanding of antennas has been improved and expanded. Yours can too using examples within the pages of this book.

Download or read book Foundations of Electromagnetic Compatibility written by Bogdan Adamczyk and published by John Wiley & Sons. This book was released on 2017-05-01 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is currently no single book that covers the mathematics, circuits, and electromagnetics backgrounds needed for the study of electromagnetic compatibility (EMC). This book aims to redress the balance by focusing on EMC and providing the background in all three disciplines. This background is necessary for many EMC practitioners who have been out of study for some time and who are attempting to follow and confidently utilize more advanced EMC texts. The book is split into three parts: Part 1 is the refresher course in the underlying mathematics; Part 2 is the foundational chapters in electrical circuit theory; Part 3 is the heart of the book: electric and magnetic fields, waves, transmission lines and antennas. Each part of the book provides an independent area of study, yet each is the logical step to the next area, providing a comprehensive course through each topic. Practical EMC applications at the end of each chapter illustrate the applicability of the chapter topics. The Appendix reviews the fundamentals of EMC testing and measurements.

This book was released on 2018-03-30 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis proposes a reliable and repeatable method for implementing Spoof Surface Plasmon (SSP) modes in the design of various circuit components. It also presents the first equivalent circuit model for plasmonic structures, which serves as an insightful guide to designing SSP-based circuits. Today, electronic circuits and systems are developing rapidly and becoming an indispensable part of our daily life; however the issue of compactness in integrated circuits remains a formidable challenge. Recently, the Spoof Surface Plasmon (SSP) modes have been proposed as a novel platform for highly compact electronic circuits. Despite extensive research efforts in this area, there is still an urgent need for a systematic design method for plasmonic circuits. In this thesis, different SSP-based transmission lines, antenna feeding networks and antennas are designed and experimentally evaluated. With their high field confinement, the SSPs do not suffer from the compactness limitations of traditional circuits and are capable of providing an alternative platform for the future generation of electronic circuits and electromagnetic systems.

Download or read book Wavelength of Oscillations Along Transmission Lines and Antennas written by Ernst M. Siegel and published by . This book was released on 1940 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a well-known experimental fact that the wavelength of an oscillation along an antenna or an open-ended transmission line differs from the wavelength of the same oscillation in free space, but there did not exist a basic scientific explanation of this phenomena until now. The following paper deals with the above problem from a theoretical point of view and demonstrates that the shortening of the wavelength is caused by a terminal effect, due to the change of inductance and capacitance near the end of a transmission line or the top of an antenna. The general differential equations for a transmission line of variable characteristic impedance are derived and solved for the first time for the particular case of the antenna and of the terminal zone of a transmission line. By means of the results obtained, numerical values for the shortening of the first halfwave are computed which are in good agreement with the values known from experience. The above derivations are of particular practical and theoretical importance for transmitting antenna design.
