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 recog. 590 O'Reilly|bO'Reilly Online Learning: Academic/Public Library Edition 650 0 Ultra-wideband antennas|vCongresses. 650 6 Antennes à ultralarge bande|vCongrès. 650 7 Ultra-wideband antennas|2fast 655 7 Conference papers and proceedings|2fast 700 1 Begaud, Xavier. 776 08 |iPrint version:|aAntennes ultra large bande.
