Circularly Polarized Substrate Integrated Dielectric Resonator Antenna

Abstract

This paper proposes a novel circularly polarized (CP) substrate integrated dielectric resonator antenna (SIDRA). It is fed by a half-mode substrate integrated waveguide (HMSIW) through a pair of cross-slots. The feeding HMSIW and radiator of the proposed SIDRA can be fully integrated together based on the simple printed circuit board (PCB) technology. The proposed antenna has the merits of low profile, low cost, high efficiency, and easy integration.
