Many monopole UWB antennas have been developed over the years. One common problem is that their performance is heavily affected by the ground plane. In this paper, a new approach on how to reduce the ground plane effects on such antennas is proposed: L-shape cuts on the edge of the ground plane are introduced and it is shown that this method changes the current distribution on the ground plane without sacrificing the frequency and time domain performance, which makes such antennas more suitable for real applications with different sizes of the ground plane.
