A wideband antenna with fan-shaped and trapezoidal elements for Ultra Wideband radio

摘要

In recent years, wireless communications using Ultra Wideband (UWB) technology are promising in order to materialize the ubiquitous world what is called [1]. Antennas for UWB communications, using a frequency range of 3.1 GHz to 10.6 GHz, require suitable broadband characteristics as compared with antennas for conventional wireless communications.
