In this paper we use a novel model of quasi yagi microstrip antenna with high gain and directivity. Slot is placed within the patch which helps to increase the front to back ratio and increase the gain of the antenna. Surface currents are more in the slot area that we have designed. The prototype of the antenna covers frequency range of 2-6 GHz with VSWR less than 1.2. The antenna has high gain between 5-7dBi and has high directional pattern. It is useful for Wi-MAX and other WLAN applications.fatcat:fiadudlbdzfthfetyewlirhrxy
