This exciting new book focuses on the analysis and design of reconfigurable antennas for modern wireless communications, sensing, and radar. It presents the definitions of basic antenna parameters, an overview of RF switches and explains how to characterize their insertion loss, isolation, and power handling issues. Basic reconfigurable antenna building blocks, such as dipoles, monopoles, patches and slots are described, followed by presentations on frequency reconfigurable antennas, pattern reconfigurable antennas, and basic scanning antenna arrays. Switch biasing in an electromagnetic environment is discussed, as well as simulation strategies of reconfigurable antennas, and MIMO (Multiple Input Multiple Output) reconfigurable antennas. Performance characterization of reconfigurable antennas is also presented. The book provides information for the technical professional to design frequency reconfigurable, pattern reconfigurable, and MIMO antennas all relevant for modern wireless communication systems. Readers learn how to select switching devices, bias them properly, and understand their role in the overall reconfigurable antenna design. The book presents practical experimental implementation issues, including losses due to switches, materials, and EMI (Electromagnetic Interference) and shows how to address those.

This new authoritative resource presents the basics of network analyzer measurement equipment and troubleshooting errors involved in the on-wafer microwave measurement process. This book bridges the gap between theoretical and practical information using real-world practices that address all aspects of on-wafer passive device characterization in the microwave frequency range up to 60GHz. Readers find data and measurements from silicon integrated passive devices fabricated and tested in advance CMOS technologies. Basic circuit equations, terms and fundamentals of time and frequency domain analysis are covered. This book also explores the basics of vector network analyzers (VNA), two port S-parameter measurement routines, signal flow graphs, network theory, error models and VNA calibrations with the use of calibration standards.

Antennas, power lines, microwave ovens, color TVs, VDTs, radar, and the RF sealers used in many industries may or may not cause harmful physical effects. In this book, Nicholas Steneck takes an objective look at the multifaceted and still unresolved debate involving government, the public, and industry over the safety and use of microwaves and radio-frequency radiation. In the process he raises important issues of conflicting values, vested interests, and scientific uncertainty. Steneck traces the origins of the debate to the 1930s, when scientific research concentrated on the therapeutic, thermal aspects of radio-frequency radiation, and he also covers such recent aspects of the story as the irradiation of the U.S. Embassy in Moscow and the continuing controversies over the siting of satellite communication antennas. Nicholas H. Steneck is Professor of History and Director of the Collegiate Institute for Values and Science at the University of Michigan.
