Abstract: This paper offerings a reconfigurable elliptical UWB antenna with dual band rejection characteristics. This antenna is modelled on 38 X 40 mm2 FR4 substrate. It has ability in wisely handle the issue of interferences comes from the Wi-MAX 3.3GHz-3.7GHz, X-Band satellite communication uplink frequency 7.9GHz-8.4GHz. Two U-Shaped slots one is 28mm created on the patch and another 11.1mm placed on the feed line to achieve band rejection at Wi MAX and X-Band satellite uplink band. Two PIN Diodes are placed on the slots to get on demand band rejection. The antenna is constructed and simulated using HFSS. The planned antenna has VSWR< 2 from 3-11 GHz.
