A detailed and timely overview of recent developments in active quasi-optical arrays In recent years, active quasi-optics has emerged as one of the most dynamic fields of contemporary research—a highly unconventional approach to microwave and millimeter-wave power generation that integrates solid-state devices into a single quasi-optical component in which all devices operate in unison. This book defines and describes active quasi-optical arrays, reviews the current state of the art, and answers numerous basic and technical questions on the design, analysis, and application of these devices. The contributors to this volume are leading researchers in the field who present results and views from government, industrial, and university laboratories and offer a balanced discussion on a high technical level. They also offer insight into the applicability and commercial value of this technology for military systems, manufacturing processes, communications, and consumer products. Topics presented include: Analysis and design methodologies for quasi-optical active arrays Power-added and power-combining efficiencies of quasi-optical amplifier arrays Phase-shifterless beam steering in oscillator and amplifier arrays Integrating quasi-optical active components into a compact subsystem Design and fabrication of quasi-optical oscillators, amplifiers, multipliers, and tuners Characterization and measurement of quasi-optical components

This is the only book currently available that covers this subject. The authors piece together information from diverse areas which is essential to understand integrated and integrated active antennas. Emphasis is placed on active antennas and power combining applications, consolidating the work from numerous researchers. Early chapters lay the foundation for oscillator, antenna, array and power combining theory. Chapter five discusses important testing parameters and techniques for active antenna measurements and includes definitions for equivalent isotropic radiated power, locking gain and locking bandwidth. The last chapter sheds light on beam steering, a more recent development in active antenna arrays. Contains over 200 illustrations.

Describing an innovative approach to phased-array control in antenna design This book explores in detail phased-array antennas that use coupled-oscillator arrays, an arrangement featuring a remarkably simple beam steering control system and a major reduction in complexity compared with traditional methods of phased-array control. It brings together in one convenient, self-contained volume the many salient research results obtained over the past ten to fifteen years in laboratories around the world, including the California Institute of Technology's Jet Propulsion Laboratory. The authors examine the underlying theoretical framework of coupled-oscillator systems, clearly explaining the linear and nonlinear formalisms used in the development of coupled-oscillator arrays, while introducing a variety of state-of-the-art methodologies, design solutions, and tools for applying this control scheme. Readers will find: Numerous implementation examples of coupled-oscillator array prototypes A continuum model that permits application of diffusion theory to the analysis of phase dynamics A demonstration of the array behavior through experimental results that validate the linearized theory Examples of how incorporating coupling delay restores causality, including the latest published results Guidance on how to accurately analyze and optimize coupled-oscillator arrays using modern simulation tools A review of current developments, including the design of compact couple-oscillator array antennas Complete with 150 diagrams and photographs, Coupled-Oscillator Based Active-Array Antennas is a highly useful tutorial for antenna designers and a valuable reference for researchers and engineers wishing to learn about this cutting-edge technology.

This comprehensive new resource guides professionals in the latest methods used when designing active integrated antennas (AIA) for wireless communication devices for various standards. This book provides complete design procedures for the various elements of such active integrated antennas such as the matching network, the amplifier/active element as well as the antenna. This book offers insight into how active integration and co-design between the active components (amplifier, oscillator, mixer, diodes) and the antenna can provide better power transfer, higher gains, increased efficiencies, switched beam patterns and smaller design footprints. It introduces the co-design approach of active integrated antennas and its superior performance over conventional methods. Complete design examples are given of active integrated antenna systems for narrow and wideband applications as well as for multiple-input-multiple-output (MIMO) systems. Readers find the latest design methods for narrow and broadband RF matching networks. This book provides a complete listing of performance metrics for active integrated antennas. The book serves as a complete reference and design guide in the area of AIA.
