Dual Band Defected Ground Microstrip Patch Antenna for WLAN/WiMax and Satellite Application
A microstrip patch antenna for Wi-Max and GSM application is proposed. The antenna has a frequency bandwidth of 1.24 GHz (4.6053 GHz - 5.8481 GHz) for WLAN and Wi-Max and 1.04 GHz (6.124 GHz - 7.16 GHz) for Satellite application. The microstrip antenna has a planar geometry and consists of a defected ground, a substrate, a patch, a feed, one slot in patch and a defected ground which consists of a pie slot and reduced area from all three sides except the feed side. The basic theory and design are analyzed, and simulation using CST Microwave Studio commercial software is employed to optimize the antenna's properties.
