In this paper a compact planar Ultra Wide Band (UWB) antenna with dual band-notched behavior is proposed. Two U shaped slots are etched in it for getting the dual notch behavior. The presented antenna is successfully designed, simulated and measured. The designed antenna is showing band notch property at 5.7GHz and 7.9GHz as both these bands interfere with the UWB frequency band. This antenna is designed on Fr-4 substrate with dielectric constant 4.3 and thickness of 1.6mm. The size of antenna is compact, patch dimension 34 X 27mm2.
