Abstract

The purpose of this letter is to demonstrate monolithic fabrication of an array of dielectric resonator antennas (DRAs) using ceramic stereolithography. Design and measurements of a eight-by-eight array of rectangular DRAs composed of four monolithic four-by-four array blocks are presented. The array elements are designed over a ground plane and fed by a standard aperture-coupled microstrip corporate feed network. It is shown that the corporate feed, and not the DRAs, is mainly responsible for losses in the radiating structure
