Design of a Compact PIFA for WLAN Wi-Fiwireless Applications

With recent advancements in electronics communication technologies more and more compact and powerful electronics devices are coming up with wireless communication capabilities, Not only computers or mobile now even vehicles are equipped with wireless communication capabilities, this advancement create need for new antennas to be developed to fit the new device and service requirements. In this paper a study of Planar Inverted F Antenna is presented. PIFA is most commonly used antenna especially in mobile communication because of its simplicity and low cost, though it suffers bandwidth limitations, some methods used for improvement in bandwidth and reduction in antenna volume are also discussed here. A compact PIFA is also proposed for WLAN Wi-Fi applications. The simulation results for RL is shown and effect of antenna dimension on simulation results has also been discussed.
