Dual Band Planar Inverted F Antenna with Bandwidth Enhancement for WiMAX Band
A compact dual-band Planar Inverted-F Antenna (PIFA) with parasitic element for bandwidth enhancement and reduced size working in Global Positioning System (GPS), GLONASS (GLObal NAvigation Satellite System) and WiMAX (Worldwide interoperability for Microwave Access) bands is presented. An "L" shaped slot in radiating plate is used to generate second resonating frequency. The parasitic element and slot are properly dimensioned and separated to generate the resonance at the designed frequencies. The antenna is simulated using finite element method based simulator and fabricated using 0.1mm thin copper foil. The designed PIFA exhibits good radiation characteristics and moderate gain with compact size.
