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.

Editorial Reviews

An introduction to the theory and practice of active antenna design and power combining, integrating areas of solid-state devices, antennas, and microwave circuits. The volume provides background theories, and reviews the methods and concepts behind power combining and synchronization, all active integrated devices on microstrip patches, grids, notches, and other antennas. These devices are applied to transmitters and power combining arrays, concluding with beam steering. The discussions feature 250 illustrations, and offers application examples. Annotation c.

Meet the Author

JULIO A. NAVARRO, PhD, is an engineer at Epsilon Lambda Electronics Corporation, where he designs and develops microstrip and waveguide antenna arrays from X- to W-band; specifically, microstrip patch antenna arrays that operate at 24, 35, 60, 77, and 94 GHz. He is currently working on efficient feeding methods for large phased arrays and collision warning systems for the automotive market. Dr. Navarro received his degree from Texas A&M along with a Graduate Engineering Fellowship in 1989, a National Science Foundation Fellowship in 1991, the Edensbarger Electrical Engineering Award in 1992, and a NASA-Lewis Training Grant in 1993. He has published over 20 technical papers and holds two patents in the microwave field.

KAI CHANG, PhD, is the E-Systems Endowed Professor in the Department of Electrical Engineering at Texas A&M University, where he teaches and performs research in microwave devices and circuits. Dr. Chang received his degree from the University of Michigan and has received several awards, including the Special Achievement Award from TRW, the Halliburton Research Excellence Award, Distinguished Teaching Award, and Distinguished Research Award from Texas A&M University. He has authored the book Microwave Solid-State Circuits and Applications (published by Wiley in 1994), edited the four-volume Handbook of Microwave and Optical Components, contributed chapters to a number of books, and has published over 250 technical papers on microwave circuits, components, antennas, and subsystems.
