The proper design of commercial ultra-wideband (UWB) devices of civil areas of data communication, imaging, and radar requires an in-depth understanding of the both the UWB communication channel and t...e antenna elements. Combining theoretical treatment with practical examples, the editors (affiliated with France Telecom R&D and the UK's U. of Oxford, U. of Manchester, and BAE Systems Advanced Technology Centre) present 21 chapters, beginning with discussions of fundamental electromagnetic theory, basic antenna elements, antenna arrays, beamforming, and antenna diversity techniques. They then present a section on antennas for UWB communications covering the theory of UWB antenna elements, antennal elements for impulse radio, planar dipole- like antennas for consumer products, UWB antenna elements for consumer electronic applications, UWB arrays, and UWB beamforming. Propagation measurements and modeling is discussed in chapters on analysis of UWB signal attenuation through typical building materials, large- and medium-scale propagation modeling, small-scale UWB propagation modeling, antenna design and propagation measurements and modeling for UWB wireless body area networks, and UWB spatial channel characteristics. The remaining contributions introduce localization in non-line of sight scenarios with UWB antenna arrays, antennas for ground-penetrating radar, wideband antennas for biomedical imaging, and UWB antennas for radar and related applications.
