PIFA with improved characteristic for wireless communication

In this paper, a Planar Inverter F antenna with improved characteristics has been presented. Planar Inverted F Antenna (PIFA) is used for wireless communication mainly in mobile communication. The PIFA generally have low efficiency, gain and bandwidth when mounted on normal conductive ground plane but when it is placed on defective ground structure (periodically spaced holes on ground plane), it mitigates its defect by reducing the spurious radiation. The EBG substrate enhances the characteristics of PIFA in terms of gain and efficiency due to suppression of surface waves that are being generated in case of normal conductive ground plane.
