Compact Dual Band PIFA for GPS and WiMAX
A compact Planar Inverted F Antenna (PIFA) as the element for dual band operation in 1.48GHz Global Positioning System (GPS) and 3.2GHz Worldwide interoperability for Microwave Access (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.
