Abstract:
1. A method of forming overlapping antenna subarrays, comprising: forming one or more first-level subarrays by combing a plurality of elements, each first-level subarray having a phase center; and forming one or more second-level subarrays by arranging a plurality of the first-level subarrays to form each second-level subarray, wherein: a) the first-level and second-level subarrays comprise overlapping antenna subarrays, b) each of the plurality of elements comprises an antenna element, c) at least some of the first level or second-level subarrays include an interlocking feature that allows interlocking of each subarray with another one of the same subarray, d) arranging comprises interlocking, and e) the phase center of the first-level subarray comprises an electrical center, and is controlled to be positioned near a center of the first-level subarray.
