Abstract

We demonstrate a low-profile, compact antenna consisting of a cross dielectric resonator on a microstrip patch and a quasi-planar surface mounted short horn (SMSH). The measurements show a 10 dB return loss bandwidth from 6.07 GHz to 7.52 GHz (21.3%) and a gain better than 9.0 dBi over this bandwidth. The total height of the antenna is only 8.61 mm and the aperture size is 48.1 mm X 43.1 mm. The cross-polarization level of the antenna at boresight is better than 28 dB in both E-and H-planes over the impedance bandwidth.
