Abstract
In this article, a compact dielectric resonator antenna array was proposed for microwave imaging systems. Four resonator elements of Roger RT/Duroid 6010 were used over the FR4 substrate for an array configuration with a total size of 35 × 50 × 7 mm. The proposed antenna array attained wide operational bandwidth of 6 GHz ranging from 12 to 18 GHz making antenna effectively operational for whole Ku-band. The demonstrated antenna along with being wide-band and small size, possessed essential performance characteristics like appropriate gain, stable radiation patterns, and high radiation efficiency over the entire band, therefore, making proposed antenna a prospective candidate for microwave imaging.
