Gain Enhancement of Circular Microstrip Patch Antenna Using Dual-FSS Superstrate Layer for ISM Band

Abstract

In this paper, an effort is made to optimize the gain to show better performance analysis on the basis of design and simulation results by implementing FSS structured superstrate layer with circular microstrip patch antenna at operating frequency of 5.8 GHz for ISM Band applications. In this proposed antenna, co-axial feeding technique is utilized in order to have better impedance matching effects. In order to show our results better, we have made a comparative analysis with conventional microstrip patch antenna at the same frequency band to increase the gain, directivity and minimize the return loss of the desired antenna. In addition to this, it shows the advantages of utilizing the ism band and fss superstrate layers compared to other frequency bands. Full wave 3-D simulation results is carried out by using Ansoft based HFSS software, that is, based on Finite Element Method (FEM) modeling technique.
