A substrate-integrated dielectric resonator, which includes a first substrate layer having a first dielectric constant, and a plurality of metallic patches on a first side of the first substrate layer. The plurality of metallic patches is separated from each other, and is shorted to ground. A dielectric resonator antenna incorporating such a resonator is also described. The DRA has a low profile with an enhanced gain. The DRA can be easily fabricated using low-cost PCB technology. By adding shorted metallic patches to the DR without increasing the antenna size, the gain of DRA is obviously increased.
