A compact ultra-wideband (UWB) dual notch band antenna is presented. The proposed antenna possesses staircase typed radiating patch with half a ground, rectangular- and square-shaped complementary split ring resonators (CSRR) which are used for realizing ultra-wideband performance and filtering effects in the antenna structure, respectively. Filtering structure has a small size of 32 × 20 × 1.6 mm3, and notching frequencies are obtained at 5.8/5.9 GHz and 8.3 GHz in the ultra-wideband region. Antenna has better reflection coefficient performance from 3.1 to 14 GHz and with filtering effect. Further, it has better radiation characteristics in the desired frequency bands.
