摘要

A compact coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with a band-notched performance is presented in this paper. The band-notched UWB antenna is designed on a 26X 34X 1.6 mm(3) substrate. It consists of a circle ring with a T-shape construct, three rectangular matching branches, a rectangular transition branch, and a CPW feed line. The antenna is simulated and the geometrical parameters of the antenna selected with Ansoft HFSS. The simulated results show the impedance bandwidth covers from 3.0 GHz to 11.0 GHz with the notched rejection band of 5.1 GHz - 5.8 GHz. A prototype was fabricated and tested. The measured and simulated results show that the proposed antenna gives bidirectional radiation pattern in the E-plane and omnidirectional radiation pattern in the H-plane with relatively flat gains in the pass-band. Due to its compact configuration, the antenna can find good UWB applications.
