Abstract
A modularly expandable, phased array antenna having a rhomboidal shaped antenna aperture formed by a plurality of rhomboidal shaped subarrays. Each subarray has a rhomboidal shaped printed wiring board on which is formed a plurality of antenna elements, where the elements collectively form a rhomboidal shape in accordance with the printed wiring board. The rhomboidal shaped subarrays enable a modular aperture to be formed without producing any gaps between columns or rows of adjacently positioned subarrays. Thus, a uniform, consistent spacing is maintained between all the antenna elements on the subarrays. This improves antenna radiation and low observability performance for the antenna system, as well as reducing the overall size of the antenna aperture and its cost of construction.
