A 20 GHz 2 × 2 subarray radiator of microstrip‐fed cavity‐backed circularly polarized horn is presented. Since horn antennas incorporating waveguide types of circular polarizers have big size of radiator height, microstrip feeding and polarization is proposed and cavity‐backed introduced to improve radiation performance. Two approaches of single and 2 × 2 subarray of horn are compared to be a basic radiation element of an array antenna. © 2006 Wiley Periodicals, Inc.
