Microwave Ring Circuits and Related Structures

This edition of Microwave Ring and Related Structures, Circuits, and Antennas incorporates the latest material on ring circuits and applications. This edition covers the following new topics: the parallel plate waveguide model, using both rectangular and circular ring configurations, and disk geometris and sprial inductors, which have wide usage in RF and microwave circuits.

Informationen zum Autor KAI CHANG, PhD, is the Raytheon E-Systems Endowed Professor in the Department of Electrical Engineering at Texas A&M University where he teaches and performs research in microwave devices, circuits, and antennas. In addition to publishing more than 400 technical papers and twelve books on microwave circuits, components, antennas and subsystems, Dr. Chang is an award-winning author, editor, and Fellow of the IEEE. His awards include a Special Achievement Award from TRW, the Halliburton Research Excellence Award, the Distinguished Teaching Award, and the Distinguished Research Award from Texas A&M.LUNG-HWA HSIEH is a doctoral student at Texas A&M University. He has authored more than fifteen papers on microwave ring circuits. He was previously a senior design engineer at General Instruments involved in RF design. Klappentext The definitive text on microwave ring circuits-now better than everFor the past three decades, the ring resonator has been widely used in such applications as measurements, filters, oscillators, mixers, couplers, power dividers/combiners, antennas, and frequency-selective surfaces, to name just a few. The field has continued to expand, with many new analyses, models, and applications recently reported.Microwave Ring Circuits and Related Structures has long been the only text fully dedicated to the treatment of ring resonators. The second edition has been thoroughly revised to reflect the most current developments in the field. In addition to updating all the original material, the authors have added extensive new coverage on:* A universal model for both rectangular and circular ring configurations* Applications of ring structures for all types of planar circuits* A new transmission line analysis* An abundance of new applications in bandpass and bandstop filters, couplers, oscillators, and antennasWhile retaining all the features that made the original text so useful to both students and teachers in the field, the second edition seeks to introduce the analysis and models of ring resonators and to apply them to both the old and the new applications, including microstrip, slotline, coplanar waveguide, and waveguide transmission lines. Based on dissertations and papers published by graduate students, scholars, and research associates at A&M University, Microwave Ring Circuits and Related Structures, Second Edition is sure to be a valuable addition to both engineering classrooms and research libraries in the field.
