In this paper, a novel double notched UWB antenna is introduced. The proposed antenna is Quasi Self-Complementary (QSC) with wide impedance bandwidth from 2.2 GHz to more than 12 GHz. The antenna consists of semi-ring with rectangular tapered section for more matching and it is designed on FR-4 substrate with thickness 1.5 mm and has compact size of 11.5 × 14.5 × 1.5 mm3. The dual notched bands are achieved by using a T-shaped slit etched in the radiating patch to reject interference with WIMAX band and two C-shaped are placed close to the microstrip feed line to reject the interference with the WLAN band. The proposed antenna is designed, simulated and measured. All simulation results are performed using the CST software. Good agreement is presented between the experimental and the simulated results.
