The Art and Science of Ultrawideband Antennas


Hans Schantz

Artech House

340 pages



Ultra-wideband (UWB) technology is on the cutting edge of contemporary wireless development and this comprehensive treatment of UWB antennas serves as an invaluable practical reference for your antenna and RF design work. Generously supported with over 200 equations and more than 200 illustrations, this authoritative volume enables you to select the proper UWB antennas for your applications, design and analyze UWB antennas, and integrate these antennas in an RF system. You get a concise discussion on UWB antenna characteristics that allows you to quickly and correctly apply them to your projects without being bogged down by unnecessary theory. From impedance matching and a survey of time domain electromagnetics, to a taxonomy of UWB antennas and coverage of a novel approach to antenna physics involving electromagnetic energy flow, this all-encompassing book provides the hands-on, system-level knowledge you need to realize the performance benefits of ultra-wideband technology. What’s more, the book includes a complete overview of the history and development of UWB antennas, helping you to build and improve existing designs rather than reinventing them.
