دانلود کتاب Ultra Wide Band Antennas

Ultra Wide Band Technology (UWB) has reached a level of maturity that allows us to offer wireless links with either high or low data rates. These wireless links are frequently associated with a location capability for which ultimate accuracy varies with the inverse of the frequency bandwidth. Using time or frequency domain waveforms, they are currently the subject of international standards facilitating their commercial implementation. Drawing up a complete state of the art, Ultra Wide Band Antennas is aimed at students, engineers and researchers and presents a summary of internationally recognized studies.Content: Chapter 1 Applications of Ultra Wide Band Systems (pages 1–32): Serge Hethuin and Isabelle BucailleChapter 2 Radiation Characteristics of Antennas (pages 33–59): Xavier BegaudChapter 3 Representation, Characterization and Modeling of Ultra Wide Band Antennas (pages 61–112): Christophe RoblinChapter 4 Experimental Characterization of UWB Antennas (pages 113–161): Christophe DelaveaudChapter 5 Overview of UWB Antennas (pages 163–212): Nicolas Fortino, Jean?Yves Dauvignac, Georges Kossiavas and Xavier BegaudChapter 6 Antenna?Channel Joint Effects in UWB (pages 213–238): Alain Sibille
