A novel crescent shaped slot UWB antenna with band notch characteristics

A novel compact ultra-wideband (UWB) antenna with wideband and band notch characteristics is presented. Simulation of the designs is done using HFSS 12.1 and the return loss parameters of the two designs along with radiation patterns are presented. The wideband design is an omega type structure which gives a wide band width of approximately 8.3 GHz from 2.6Ghz to 10Ghz. Notched band characteristics in second design of 5.15-5.5GHz is achieved by cutting a crescent shaped slot in the radiating patch operating for the centre frequency bands of 3.6 GHz and 5.8 GHz. Simulated results show that the designs are good candidates for the UWB applications.
