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 ...
