Gain Enhancement of Microstrip Patch Antenna using Array Configuration – A survey

Abstract: Minimizing return losses and maximizing gain are important issues in the design of microstrip patch antenna. High gain microstrip patches antenna find an optimal arrangement of patches in order to improve antenna performance. For example, in long distance applications, only an optimal microstrip patch antenna that fully covers the monitored area can be applied. In this paper, we address the optimal planning of patch arrangement on dielectric substrate. We seek an technology that maximizes radiations from patch while ensuring simultaneously full power transmission. First, we design a microstrip patch antenna using HFSS (high frequency structure simulator). Then, we implement a array structure, increasing the size of antenna .Experimental results show that the proposed antenna provides low return losses and VSWR.
