Abstract

In this article, recent patents on UWB antennas are reviewed; different geometries, design parameters and their experimental results are discussed. Several types of UWB antennas including special horn, patch and array antennas in recent patents are explained together while comparing their measured return loss, gain and radiation patterns. Projections to the future developments of UWB antenna technology are also given.

Keywords: Ultra wide band (UWB) antenna, patch antenna, horn antenna, Vivaldi antenna
