It is designed for ultra-wideband （UWB） wireless communications and applications over the band 3.1-10.6 GHz. This antenna consists of a circular patch with notch-cut fed by a microstrip line, one transition step, and a partial ground plane. The 2： l voltage standing wave ratio （VSWR） bandwidth （Sll 〈-10dB） of the proposed antenna covers the entire UWB application range specified by Federal Communications Commission （FCC） that is from 3.1 to 10.6GHz. The proposed antenna is able to achieve an impedance bandwidth about 8.6 GHz （2.4-11 GHz）. The return loss, VSWR, radiation pattern, radiation efficiency, gain, distribution of the proposed group delay, and current antenna are included in this paper. The simulation results and proposed antenna design details are presented by CST Microwave Studio.展开更多
