The paper presents a microstrip patch antenna with dual band-notched characteristics. The proposed antenna is fed by a thin microstrip patch and provides band-notched characteristics by etching 2 symmetric C-shaped notches and one hollow cylindrical arc-shaped notch and notched partial ground. The antenna size was 30×19 mm2, covering a range from 2.8-12.3 GHz. The UWB covers a large band of frequencies including WLAN band (4.75-5 GHz) and the X-Band (7.75-8.35 GHz). To prevent interference with the operation of our antenna and devices operating in these bands, the frequencies are rejected through notches in the antenna. The simulated results show that the VSWR of the antenna is <-10 in the radiating bandwidth. This can be used in wireless applications.
