Planarized Flag-Type directive UWB antenna

Abstract

In this paper, a planarized directive UWB antenna is designed based on a revolution-surface body. The antenna performs from 5.2 GHz to 10.8 GHz with a highly stable directive radiation pattern, an average front to back lobe ratio of 20 dB and an absolute gain of 9.5 dB, all over the bandwidth.
