A microstrip fed ultra-wideband (UWB) antenna with different band rejection techniques is presented. The designed antennas consist of a defected ground plane with an elliptical slot and elliptical shaped radiating element. The measured and calculated impedance bandwidth of the proposed antenna ranges from 2 to 5 GHz for a return loss (S11) less than 10 dB. Also, it has a relatively stable radiation patterns over its whole frequency band of interest
