Abstract

This paper presents a flat and low-profile perforated dielectric phase correcting structure (P-PCS) design for conventional electromagnetic bandgap resonator antennas (ERAs). The P-PCS makes use of effective permittivity variation of dielectric material in distinct phase correction regions created on the surface of ERAs. The permittivity variation is realized by drilling holes of appropriate sizes in a planar slab of same dielectric material. The peak directivity of the ERA with P-PCS increases by 9 dB, which is similar to that achieved by height varying dielectric PCS. The P-PCS is an attractive alternative because of its planar geometry and 73% smaller thickness as compared with height-varying dielectric PCS.
