Design optimization of PBG based PIFA system using soft computing techniques

Planar inverted F antennas have wide range of applications in wireless industry those includes mobile handset antennas, wireless sensors in aircraft fuel tanks to check the fuel availability status etc. One of the game changing technologies of wireless industry is design and development of compact, light weight antenna with low specific absorption rate. The antenna size can significantly be reduced by introducing metamaterial structures. In this paper, design optimization of a photonic band gap structure based compact, high impedance bandwidth planar inverted F antenna has been reported. The optimized antenna shows an impedance bandwidth of 39.9% and a gain of 6.03 dB whereas the conventional PIFA is of 25.4% only.
