In this paper, a printed, compact & ultrawideband (UWB) antenna used for three band notch characteristics are reported. Ultra-wideband (UWB) is one of the recent topics that received a great concern from academic and industry. However, UWB found many difficulties to be standardized due to the overlay working that made UWB an important potential interference source to many licensed and unlicensed spectrum throughout the band 3.1-to-10.6 GHz. In this paper we propose a compact ultra-wideband microstrip antenna with triple band notched 3.5 GHz, 4.9 GHz and 9.3 GHz. The proposed antenna consists of a curved patch with a partial ground plane that is fed by 50 Ω microstrip line. In this antenna notch filter achieved using small rectangular metallic strip with different size and positions. The notch frequency can be obtained by varying the length of rectangular metallic strip. Moreover, the proposed antenna provides good radiation patterns across the working bands and a relatively flat gain over the entire frequency band excluding the rejected bands.
