On Some Investigations on Ultra Wide Band Antenna using HFSS

This article deals with the Ultra-Wide Band (UWB) [1-2]antennas that are appraised in respect of various geometries, antenna design parameters and their experimental results. Several types of UWB antennas including special horn, micro-strip patch and array antennas in recent works are elucidated, while comparing their measured return loss, gain and radiation patterns. Projections to the long run developments of UWB antenna technology also are discussed here.
