In this paper, the effect of 1x1 and 3x3 square and circular parasitic patches are placed on the FR4 layer and there effect on the various parameters of the antenna are compared. A microstrip antenna fed high gain antenna using array of parasitic patches on a FR4 superstrate layer is proposed. The suspended microstrip antenna is fabricated on FR4 substrate and placed at 1mm from ground. This suspended MSA feeds array of square as well as circular parasitic patches which are fabricated on a 1.59mm thick FR4 layer.
