On the use of beam-forming matrices for building overlapped subarrays with flat-topped radiation patterns

Comparative analysis of the subarray factor shape and subarray architecture complexity is carried out for an approach proposed recently to building linear arrays of overlapped subarrays for limited field of view based on using beam-forming matrices. The comparisons are performed with other array architectures including arrays with the known chess board network. The issue of application of the approach to building planar arrays of overlapped subarrays is also briefly addressed.
