Abstract :
A wideband metamaterial antenna employing SRR loading is presented. Two designs were simulated, fabricated and measured. The bandwidth enhancement is achieved by loading SRR resonator onto a conventional monopole antenna. The SRR excited a lower resonance frequency mode which matches with the resonance frequency of the monopole antenna thereby extending the overall impedance bandwidth from 26% to 91%. The antenna has a compact size of 30 × 26 mm2. The peak realized gain and efficiency of 3.2 dB and 76% are obtained respectively. The antenna has potential applications for WLAN and WiMAX operations.
