Abstract :
In this paper, a simple, low-profile, and wideband planar antenna with a pure rectangular radiator fed by a simple 50Ω microstrip line for multiple applications is designed. By investigating the feeding position and ground plane size, the antenna is properly designed to have a very wide bandwidth covering the whole FCC allocated ultra-wideband. Due to the additional patch underneath the radiator at a proper position, the bandwidth can be further increased towards the lower side of the frequency spectrum. This antenna is finally modified to have a bandwidth ranging from 2GHz-11.3GHz, which satisfies the system requirements for SDMB, WiBro, WLAN, CMMB and the entire UWB with S1,1 <; -10dB.
