A Metamaterial Inspired Compact Open Split Ring Resonator Antenna for Multiband Operation

In this work, a metamaterial inspired compact open split ring resonator (OSRR) antenna is investigated for multiband operation. The proposed antenna uses closely employed open split rings as a radiating element which provides efficient size reduction and broader bandwidth performance. The proposed antenna with the overall size of 27.5 × 16.08 × 1.6 mm3 is fabricated and tested. The measured results indicate that it covers 2.4/5.2/5.8 GHz (Wireless LAN), 5.5 GHz (WiMAX) and 7.4 GHz (X-band downlink) applications. The OSRR antenna has achieved size reduction of 38.83% and 52.83% compared to the split ring resonator and ring antennas respectively. It is observed that the proposed antenna produces better performance than the existing antennas in the literature.
