Abstract
We demonstrate the gain of a standard rectangular dielectric resonator antenna (DRA) enhanced by integrating it with a surface mounted short horn (SMSH). An enhancement of gain by 3.8 dB to 8,3 dBi at 5.95 GHz, and a 10 dB return bandwidth of 3.2% has been achieved from this configuration. Total height of the fabricated structure is only 0.172 λ0, or 8.61 mm at 6.0 GHz, and the aperture size is 0.96 λ0 × 0.86 λ0, or 48.1 mm × 43.1 mm. The cross-polarization level of the antenna is <33 dB in both E- and H-planes.
