Описание:
An authoritative guide to the latest developments for the design of low-cost smart antennas
Traditional smart antenna systems are costly, consume great amounts of power and are bulky size. Low-cost Smart Antennas offers a guide to designing smart antenna systems that are low cost, low power, and compact in size and can be applied to satellite communications, radar and mobile communications. The authors -- noted experts on the topic -- provide introductions to the fundamental concepts of antennas, array antennas and smart antennas. The book fills a gap in the literature by presenting the design techniques of low-cost radio frequency (RF) smart antennas as well as approaches for implementing the hardware of the antenna and the beamforming network (BFN).
A comprehensive and accessible book, Low-cost Smart Antennas not only presents an up-to-date review of the topic but includes illustrative case studies that contain in-depth explorations of the theory and technology of smart antennas. While other resources highlight the software (signal processing algorithms), this book is unique by focusing on the antenna hardware. This important book:
Offers an introduction to the most recent developments of the design of low-cost smart antennas and their applications
Presents a unique book that puts the focus on antenna hardware
Includes a variety of case studies that clearly demonstrate the implementation of current design techniques
Introduces both fundamental theories as well as more advanced topics
Written for students and researchers and antenna engineers, Low-cost Smart Antennas explores the most recent advances in the field with an emphasis on antenna hardware.
Описание: This book presents the technology of millimetre waves and Terahertz (THz) antennas. It highlights the importance of moderate and high-gain aperture antennas as key devices for establishing point-to-point and point-to-multipoint radio links for far-field and near-field applications, such as high data-rate communications, intelligent transport, security imaging, exploration and surveillance systems. The book provides a comprehensive overview of the key antenna technologies developed for the mm wave and THz domains, including established ones – such as integrated lens antennas, advanced 2D and 3D horn antennas, transmit and reflect arrays, and Fabry-Perot antennas – as well as emerging metasurface antennas for near-field and far-field applications. It describes the pros and cons of each antenna technology in comparison with other available solutions, a discussion supplemented by practical examples illustrating the step-by-step implementation procedures for each antenna type. The measurement techniques available at these frequency ranges are also presented to close the loop of the antenna development cycle. In closing, the book outlines future trends in various antenna technologies, paving the way for further developments. Presenting content originating from the five-year ESF research networking program ‘Newfocus’ and co-authored by the most active and highly cited research groups in the domain of mm- and sub-mm-wave antenna technologies, the book offers a valuable guide for researchers and engineers in both industry and academia.
Описание: The book is a comprehensive treatment of the field, covering fundamental theoretical principles and new technological advancements, state-of-the-art device design, and reviewing examples encompassing a wide range of related sub-areas.

Описание: Assembled in textbook form are the important contributions to traveling wave antenna analysis, synthesis, design, wave excitation, and applications. Many of the references are not readily accessible to the English-speaking reader and it would be difficult to find this material as completely and carefully formulated elsewhere. Little more than differential and integral calculus, complex variables, and vector analysis are needed as background for this work. Copiously illustrated with graphs and diagrammatic material. The author, Dr. Carlton H. Walter, Professor Emeritus of Electrical Engineering at The Ohio State University, after reviewing antenna fundamentals and defining terms, presents analytical methods for determining the field of an antenna when the source distribution is known; the inverse problem of determining a source distribution to produce a specified field; design of a physical structure to produce a specified source distribution; traveling wave excitation; and design data for traveling wave antennas, surface wave lenses, spiral antennas, and backward wave antennas, including log-periodic antennas. Clearly written and organized, the text provides ample references and useful engineering problems at the end of each chapter. Traveling Wave Antennas is highly suitable for instruction, either as a reference in courses on antennas or as a first text on antennas at the advanced undergraduate or first-year graduate level. At the same time, the theoretician, researcher, and electrical engineer concerned with antenna design or development will find the book's design data uniquely valuable. The practical designer, too, will gain insight from it.
