A compact Ultra WideBand (UWB) monopole antenna with dual band-notched characteristics is presented. The antenna consists a square radiating patch with L shaped slots on the radiation patch and a U shaped slot as the feedline. By cutting two c-shaped slots in the ground plane, additional resonance is excited and hence much wider impedance bandwidth can produced, especially at the higher band, which results in a wide usable fractional bandwidth of more than 127% (3.1-13.2 GHz). With a pair of L-shaped structure and U slot in microstrip feedline frequency band stop performance is generated.
