Effect of Photonic Band Gap structure on Planar Antenna configuration

This paper describes the effect of Photonic Band Gap (PBG) structure as ground plane coupled with defected ground plane on Planar Antenna using coplanar waveguide with improvement of bandwidth and return loss value of 50% (in case of array of 3 × 5 UC-PBG) and 6.45 dB at resonant frequency of 3.6 GHz and is used for WIMax band (3.3 GHz to 3.8GHz) for Wireless Local Area Network (WLAN) applications.
