Abstract

EBG antennas are used for directive, omnidirectional, and sectoral applications. Nevertheless, the domain of use of these antennas can be extended to other applications where we can take advantage of their interesting performances notably in terms of directivity and compactness. One of these applications can be the broadband application where the needed bandwidths are much larger than the bandwidths offered by actual EBG antenna designs. Many solutions have been proposed in the literature to widen this bandwidth. This paper deals with the EBG band-widening method based on the use of FSS and focuses on the ability of the EBG resonator to have a broadband behavior if its upper interface is built of FSS chosen and arranged adequately. First, the behavior of the new EBG material formed by combining different FSSs, and the one of the new EBG resonator is briefly described. Then, a prototype operating in the Ku-band is proposed to validate the theoretical concept. Finally, an experimental validation is realized.
