Abstract

The Dual band notched antenna with compact dimensions which is suitable for UWB applications is proposed in this paper. The proposed antenna is able to notch band (5.1-5.8GHz) for WLAN application and (7.2-8.3GHz) of downlink X band satellite applications and International Tele communication Union (ITU) band applications.  The required band notching is achieved by cutting U slot in the feed line and H slot on the patch. The simulation of the proposed antennas has been performed using ANSYS HFSS 15.0 software. The dual band notched antenna is fabricated using FR4 substrate material having thickness 1.6mm having dielectric constant of 4.4. Important antenna performance parameters like radiation pattern, Return losses (S11) ,  VSWR and gain are measured  by simulation. The antenna is fabricated for the fabricated antenna VSWR, Return losses, Radiation pattern and gain are measured. The simulated and measured results are compared and reported.
