Abstract :
In this paper, we present our design on a simple, low-profile wideband planar antenna with a pure circular radiator fed by a 50Ω microstrip line. By investigating the feeding position and ground plane dimensions, the antenna is optimized to have a very wide bandwidth that covers the whole FCC-allocated ultra-wideband (UWB) spectrum. Because of the additional patch beneath the radiator, the bandwidth can be further extended towards the lower side of the frequency spectrum. This antenna is finally modified to have a bandwidth from 2 to 12 GHz, which satisfies system requirements for S-DMB, WiBro, WLAN, CMMB and the entire UWB with S11 <; -10dB.
