The paper proffers the procedure to model a PIN diode RF switch using full-wave EM solver, HFSS and utilizes the switch to built a simple partial ground plane antenna with omnidirectional radiation pattern. The proposed antenna has ability to tune it from ultra-wideband to narrowband mode. The frequency reconfigurability is accomplished by incorporating a rectangular slot resonator and a PIN diode RF switch embedded in the partial ground plane. The antenna demonstrates -10 dB impedance bandwidth from 500 MHz to 6 GHz in the ultra-wideband mode and 1.125 GHz to 2 GHz in the narrowband mode. A parasitic is stacked in the ground plane to improve the impedance matching and a rectangular slot is fused to explore the bandwidth-limiting possibility of the antenna. The optimization of the antenna is done by full-wave EM solver, HFSS and Specific Absorption Rate (SAR) of the antenna is examined using the equivalent flat tissue phantom. A prototype of the proposed antenna is fabricated and execution is accepted by measured results. The proposed antenna has simple and miniature structure, low SAR (0.41 W/Kg), omnidirectional pattern and low cross-polarization (
