An electronically scanned antenna may include a plurality of space-fed, contiguous subarrays arranged in an annular region, each subarray including an inner set of radiating elements facing inwardly, an outer-facing set of radiating elements, and a feed system for illuminating the inner set of radiating elements. A plurality of RF amplifiers are coupled through a commutation switch matrix to selected ones of the subarray feed horn systems to illuminate a desired sector with RF energy.
