In this letter, a simple method for reducing the size of a dual‐band planar inverted‐F antenna (PIFA) is described. This method is based on a coupling capacitor connected in parallel to the PIFA feed conductor. The proposed antenna occupies a small ground clearance of 10 mm×5 mm and is able to provide −10‐dB impedance bandwidths of 120 MHz and 760 MHz for 2.45‐GHz and 5.5‐GHz wireless local area network applications, respectively. The measured antenna efficiencies are 71.8% and 73.6%, averaged over the 2.45‐GHz and 5.5‐GHz frequency bands, respectively.
