A compact Planar Inverted F Antenna (PIFA) as the element for dual band operation in 1.48 GHz GPS and 3.2 GHz WiMAX band is proposed. PIFAs are quarter wavelength elements. Among various possible antennas, PIFAs have the advantages of low profile, compact size and are very suitable for present-day wireless communication application. A folded slit in the top plate is used to get the dual band operation. Comparison between two different orientations for folded slit is performed. A 50% miniaturization and gain improvement is achieved when the folded slit is near to the feed with an open end. The radiation pattern and current distribution on the PIFA are also plotted.
