Abstract

A novel technique for the performance enhancement of Fabry-Perot resonator antennas (FPRAs) is investigated in this paper. It has been observed, in close proximity of FPRAs, that the near field has strong non-uniform phase distribution, which compromise their characteristic of directive electromagnetic energy transmission. An all-dielectric structure referred to as phase correcting structure (PCS) is proposed to rectify and improve the phase distribution along the H-plane, by varying the thickness of a dielectric material. Significant improvement in the phase distribution of the FPRA is achieved along with more than 3dB increase in peak directivity.
