Abstract :
In this paper, a millimeter-wave aperture-coupled dielectric resonator antenna (ACDRA) with low back radiation is presented. Back radiation reduction was achieved through a circular patches-mushroom like EBG structure placed underneath the antenna. Simulated results show 18 dB improvements in the backward radiation compared to the case where no EBG is used.
