A 1.9-13.5 GHz Low-Cost Microstrip Antenna

In this paper, a low-cost ultra-wideband microstrip antenna is presented. The antenna is based on a 1.6-mm-thick FR4 substrate, is microstrip-line fed and has a partial ground plane. The return loss is more than 10 dB in the 1.9-13.5 GHz frequency range. Possible applications include 3G, Wi-Fi, WiMAX, and UWB applications. The gain results and pattern plots of the antenna are included in the paper.
