Most antennas are assembled from conducting surfaces and wires. The usual approach to numerical analysis of such structures is to approximate them by small surface or wire elements, with simple current approximation over the elements (the socalled subdomain approach), which requires a large amount of computer storage. This book describes a novel general entiredomain method for the analysis of metallic antennas and scatterers which enables the solution of a very wide class of problems to be obtained using computers of relatively modest capability.
Antennadesign engineers, scientists and graduate students interested in the analysis and design of electrically small and mediumsized metallic antennas and scatterers will find in this book a selfcontained and extremely powerful tool that circumvents most difficulties encountered in other available methods.
The objective of this book is to introduce students and interested researchers to antenna design and analysis using the popular commercial electromagnetic software FEKO. This book, being tutorial in nature, is primarily intended for students working in the field of antenna analysis and design; however the wealth of handson design examples presented in this book along with simulation details, makes it a valuable reference for practicing engineers. The requirement for the readers of this book is to be familiar with the basics of antenna theory; however electrical engineering students taking an introductory course in antenna engineering can also benefit from this book as a supplementary text.
The key strengths of this book are as follows: First, the basics of antenna simulation will be presented in a detailed, understandable, and easy to follow procedure through study of the simplest types of radiators, i.e. dipole and loop antennas, in chapters 2 and 3. This will build the fundamental knowledge a student would need in order to utilize antenna simulation software in general. Second, comparison between theoretical analysis and fullwave simulation results of FEKO are given for a variety of antenna types, which will aid the readers with a better understanding of the theory, approximations and limitations in the theoretical analysis, and solution accuracy. Third, and of paramount importance, is the visualization of the antenna current distribution, radiation patterns, and other radiation characteristics that are made available through fullwave simulations using FEKO. A proper analysis of the radiation characteristics through these visualizations serves as a powerful educational tool to fully understand the radiation behaviour of antennas
This is a professional level, introductory text on antenna principles, design, analysis, and measurements. It is especially suitable for persons who wish to improve their knowledge of antenna principles, concept design, performance analyses, and measurements. It is not a cookbooklike catalog for antenna design, nor does its understanding require a familiarity with electromagnetic theory, sophisticated mathematics, or complex computer techniques. The 3rd Edition updates and expands the original text by Lamont Blake, which was prepared at the undergraduate engineering, science, or technology level. For providing technical depth at the senior and graduate university levels, additions to the original book include a greatly expanded Chapter 7 on Antennas with Special Properties, a brand new Chapter 8 on Electronically Steered Arrays, and a revised Chapter 9 on Measurements. Also new to this edition are numerous appendices to the updated text.
Written by two leading experts in the field, this exceptional book introduces the reader to the principles, theory and applications of physical layer wireless/mobile communications. In the area of wireless, the antennas, propagation and the radio channel used are interrelated; this book offers an explanation of that relationship, which is fundamental to the development of systems with high spectral efficiency.
Channels, Propagation and Antennas for Mobile Communications emphasises the basic principles needed to establish an understanding of this technology. However, the tools required  such as the mathematics and statistics  are treated in the manner of a practical handbook, avoiding detailed derivations. The reader will develop a clear insight into the physics and effects of multipath and the use of multipath channels for communications. Propagation modelling, simulation and measurement, scattering, antenna principles, array antennas, adaptive antennas and smart antennas are also covered.
This book will be a valuable reference for senior undergraduates and postgraduates in electrical engineering and communications. Practising design engineers, systems designers and engineering managers will also gain a sound understanding of the field.
This book introduces the powerful FiniteDifference TimeDomain method to students and interested researchers and readers. An effective introduction is accomplished using a stepbystep process that builds competence and confidence in developing complete working codes for the design and analysis of various antennas and microwave devices. This book will serve graduate students, researchers, and those in industry and government who are using other electromagnetics tools and methods for the sake of performing independent numerical confirmation. No previous experience with finitedifference methods is assumed of readers.
Key features
This single volume provides a comprehensive introduction and explanation of both the theory and practice of 'Planar NearField Antenna Measurement' from its basic postulates and assumptions, to the intricacies of its deployment in complex and demanding measurement scenarios. To do this the book initially examines the properties of antennas that allow them to enhance the free space interaction of electronic systems and this leads into a full description of the theory of 'Planar NearField Scanning'.
The utility of the planar methodology is illustrated with example measurement campaigns that include discussion of the characterisation of a wide range of antennas. Advanced techniques including back transforms and polyplanar scan techniques, plus error assessment and correction, are examined and explained along with an extensive review of data assessment methodologies.
A large number of nearfield facilities exist worldwide but to the authors' knowledge no single text provides a clear stepbystep description of all the details of the 'Planar NearField Measurement Technique'. All three authors have spent a significant proportion of their professional careers involved with antenna measurements and the aim of this text is to provide the reader with a complete, comprehensive and practical text that will act as a single reference for all aspects of the measurement technique.
