Compact metamaterial-inspired frequency switchable antenna for WiMAX/WLAN application

Frequency selective metamaterial-inspired antenna for dual-frequency operation incorporating two switches (SWs) has been proposed. Length of radiating element is varied which provides easy frequency re-configurability at WiMAX (3.5-3.57 GHz) and WLAN (5-5.5 GHz). The proposed antenna offers impedance bandwidths of 13.6% (at 3.39 GHz) and 17.2% (at 5.05 GHz) with average peak gains of 1.49 dB and 1.77 dB in the working band respectively.
