Abstract

This paper presents the enhancement of microstrip antenna gain with the square aperture superstrate, placed above the microstrip antenna. The antenna is performed as the Fabry-Perot resonator with abundantly attracted properties, with high directivity and less complexity with single feed. The antenna is designed at 12.2 GHz. With the square aperture superstrate, the gain measurement result was increased to 11.95 dBi or 5.25 dB improved from microstrip antenna without superstrate. Also, the proposed antenna has a good cross-polarization discrimination over 30 dB in main lobe, both E and H planes. The square aperture superstrate designed with low complicate structure and could be created on a low cost printed broad. The prototype antenna characteristics from measurement and simulation results were presented.
