Abstract :
A slot-array-fed 1D EBG resonator antenna, presented previously, demonstrated high gain and large bandwidth. In this paper, we propose a method to reduce the overall height of this antenna, by replacing the three-layer 1D EBG superstrate with a single-layer of highly reflective frequency selective surface (FSS). A significant reduction of the antenna height from 30 mm to 12.4 mm is predicted with a 8% gain bandwidth and 24 dB gain. A 32-slot array is perforated on the metallic ground plane and is fed by a 50 Omega stripline power divider network. Theoretical results are obtained using HFSS.
