Abstract :
Deign and performance of an extremely wideband printed antenna with wireless local area network (WLAN) stop band are analyzed and presented in this paper. In the proposed antenna, an extremely wideband is achieved by modifying ground plane structure and stop band is achieved by inserting split ring resonator (SRR) in the radiating patch. Predicted impedance bandwidth of an antenna is 2.77-21.84 GHz, for VSWR <; 2. The stop band 5.20-6.04 GHz, for VSWR > 2 is achieved for rejecting WLAN (5.15-5.825 GHz) band signal. Significant gain reduction over the stop band is also observed. The antenna shows average omnidirectional radiation patterns in the passband with a compact size of 38 × 34 mm2.
