Gain and Aperture Efficiency Improvement using Uniplanar EBG Superstrate

摘要

In this paper, frequency selective surface (FSS) properties of a uniplanar electromagnetic band-gap (EBG) unit cell are used to improve the gain and aperture efficiency of a probe feed microstrip patch antenna. The unit cell shows the pass band characteristics at 7 GHz. An array of 9 × 9 unit cell is used of dimension 38.88 × 38.88 mm² to achieve gain improvement of 2.57 dB and aperture efficiency of 77.79%-86%.
