A compact size (15 × 40 mm 2 ) microstrip‐fed printed planar inverted‐F antenna (PIFA) for mobile applications operating in the GSM/DCS/PCS/UMTS/WLAN and WiMAX bands is proposed. The main structure of this antenna is simply a double‐folded PIFA with two wide open‐ended radiating sections. By tuning the dimensions of the shorter open‐ended section, optimum impedance matching can be achieved, while additional slits loaded to the longer open‐end section are for the inclusion of universal mobile telecommunications system band. To allow shifting of the higher frequencies modes so that a wide impedance bandwidth from 5 to 6 GHz can be achieved, the technique of adjusting the position of the shorting post horizontally along the ground plane is also introduced. © 2011 Wiley Periodicals, Inc.
