A novel frequency reconfigurable antenna with switchable frequency bands for WiMAX and UWB performances is designed in this letter. To generate a wide usable fractional bandwidth of 2.8–12.13 GHz, the slot on the ground plane is a rectangular slot with step at above sections. In the proposed structure a rectangular strip that act as a parasitic stub, placed on the ground plane. To achieve a reconfigurable function, a PIN diode is utilized across the rectangular strip and ground plane. When this PIN diode is biased forwardly, the parasitic stub transforms to a T–shaped strip, and by changing to this new structure, WiMAX frequency (2.85–3.75) GHz is excited. The designed antenna has a small size of 20×20 mm2 that printed on a FR4 substrate.<\div>
