A novel compact Dual Band UWB antenna

Compact ultra-wideband (UWB) antenna with dual band characteristics is presented. Simulation of the design is done using HFSS 12.1 and the return loss parameters of the design are presented. The design is an omega type in which by reducing the size and varying the centre position of the circle the dual band characteristics for the frequency of 3-3-5.1 GHz and 7.9-9.9 GHz with the bandwidth of 1.89 GHz and 2GHz with - 22dB and -32 dB return loss respectively. Simulated Results show that the design is a good candidate for the UWB Antennas.
