IEEE Microwave Magazine, 2006 The development of the broadband antenna for ultrawideband (UWB) applications such as communications, imaging, radar, and localization is discussed. UWB systems are based on transmitting and receiving impulses with extremely wide spectra. As the antennas for UWB should have broad operating bandwidths for impedance matching and high-gain radiation in ...

Directive Ultra-Wideband Planar Antennas
, 2010 Since the acceptance of unlicensed use of the Ultra-Wideband (UWB) technology in the range between 3.1 and 10.6 GHz in the USA (FCC, 2002) and more recently between 3.4 and 8.5 GHz in Europe (ETSI, 2008), the realization of low-cost UWB wireless systems is considered a fundamental research goal both for military and commercial applications.
