A novel design of dual-band reconfigurable Planar Inverted F Antenna (PIFA) is proposed in the paper. Primary radiator of the antenna consists of concentric split-ring (SR)resonators and metallic loadings appropriately placed between the rings. The compact design fed by vertical probe provides two independent dual-band operations by means of an integrated switch inserted between the rings. Dual-band reconfigurable operation of antenna is studied and demonstrated for GPS at 1.575 GHz, DCS at 1.8 GHz, WiMAX at 3.5 GHz and WLAN at 5.2 GHz applications. Also, the proposed design exhibits uniform radiation patterns at the frequency band of interests. Analysis and design of the antenna is carried out Ansoft HFSS v.13.
