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.
