Abstract

Three-dimensional Electromagnetic Band-Gap (EBG) materials have been designed, by using an in-house Fourier Modal Method (FMM) code, to be employed as directivity-enhancing superstrates for planar antennas. Alumina-woodpile samples have been fabricated. Experimental results have been collected, for the transmission properties of EBG cavities, and comparisons have been performed with FMM, with good agreement. The performances of a woodpile-covered patch antenna have been measured; the superstrate has been positioned at different distances from the antenna and its orientation has been varied; comparisons with the commercial software HFSS show a good agreement. The main effect of the EBG on the antenna performances is an enhancement of about 10 dB in maximum gain.
