Abstract

A simple electromagnetic band gap (EBG) structure is used as a superstrate to enhance the directivity of circularly-polarized (CP) corner-truncated microstrip patch antennas in two frequency bands. The EBG structure is composed of two simple unprinted identical dielectric slabs and its symmetry is exploited to transform the less directive CP beam of the patch to a highly directive CP beam. Computed results confirm the concept of this simple and novel dual-band circularly polarized EBG resonator antenna and its ability to generate CP with good axial ratio in two discrete frequency bands.
