In this paper, a planar dielectric phase correcting structure (PCS) along with partially reflecting surface (PRS) is used to enhance the gain of cylindrical dielectric resonator antenna (CDRA) up to 14.5 dBi at the design frequency of 10 GHz. PRS loaded CDRA forms electromagnetic bandgap resonator antenna (ERA). ERA gives high gain due to presence of multiple reflections between completely reflecting ground plane surface and partially reflecting dielectric surface. Non-uniform phase distribution of electric field over the ERA aperture generally degrades the radiation characteristics of antenna. In order to achieve further gain improvement, planar multi-dielectric PCS is used to transform non-uniform phase distribution to relatively uniform phase distribution over the ERA aperture.
