Free registration required

Executive Summary

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 the authors' results better, they 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.
