Abstract
An antenna array system can including a plurality of antenna subarray panels assembled together to form a single wavelength scaled aperture (WSA) antenna array. Each antenna subarray panel can include a corresponding plurality of antenna elements such that at least two antenna elements of the plurality of antenna subarray panels have different antenna element sizes. The antenna array system can include one or more beamformer circuits. Each of the one or more beam former circuits can be communicatively coupled to at least one of the plurality of antenna subarray panels. For each adjacent pair of the plurality of antenna subarray panels, each antenna element adjacent to a gap separating the adjacent pair of antenna subarray panels along an elongated boundary of the gap is greater than a predetermined value. The predetermined value can be determined based on a predefined width of the gap separating the pair of adjacent antenna subarray panels.
