Design Analysis and Performance of Elevated Ground Based Patch Antenna for WLAN Applications

This paper presents elevated ground microstrip patch antenna's performance assessment in terms of bandwidth, directivity and gain compared to a normal microstrip patch antenna. By inserting elevated ground instead of normal ground the characteristics such as gain, directivity, operating bandwidth and efficiency are improved at the resonance. The antenna has been designed and characterized for the resonance frequency of 2.4 GHz suitable for WLAN applications.
