Performance Analysis of Dual Band G-Shaped Microstrip Patch Antenna with Coaxial Feed Line for WLAN
Microstrip patch antenna is radio antenna with low profile. It consists of active patch of metal with ground plane (patch of metal).The following paper describes the dual band G shape microstrip patch antenna for WLAN application. The authors simulated this antenna by using Ansoft HFSS. The proposed antenna is G shape microstrip patch antenna with non-conductor back. This antenna is fed by coaxial cable feed. Measured value of bandwidth at -10 db is 50 MHz for lower band i.e. 2.42 GHz and 72 MHz for upper band i.e. 5.2 GHz.
