We demonstrate a novel, low-profile, compact antenna consisting of a rectangular dielectric resonator and a quasi-planar surface mounted horn. The proposed structure shows a gain of 8.5 dBi at 6.0 GHz, giving a 4.9 dB increase compared to the standard dielectric-resonator antenna (DRA) without a surface mounted horn. Total height of the fabricated structure is only 0.172 ? 0, or 8.61 mm at 6.0 GHz, and the aperture size is 0.96 ? 0 × 0.86 ?0, or 48.1 mm × 43.1 mm. The cross-polarization level of the antenna is less than 33 dB in both E-and H-planes.
