Abstract

A compact Ultra Wideband (UWB) microstrip antenna consists of a circular patch added with a three different length of open-end stub loaded Wing and partial ground plane with dumbbell shape defected ground structure (DGS) is proposed in this paper. This antenna was an improvement from the previous research, marked size reduction of 25% of the antenna size with comparable performance. The introduction of the DGS technique enables improvements in terms of bandwidth, gain and return loss characteristics. Using the model of transmission line based on 50Ω characteristic impedance, this antenna obtained a 10 dB return loss bandwidth from 3.21 GHz to 11.92 GHz.
