Mask-Constrained Synthesis of Domino-Like Tiled Phased Arrays

—In this work, the mask-constrained synthesis of domino-tiled phased arrays is addressed. By exploiting tiling theorems and theory, optimal and sub-optimal methods for the synthesis of domino arrangements and the corresponding excitations that minimize the deviation of the radiation pattern from a user-defined power mask are presented. A set of numerical examples, carried out with full-wave simulators and concerned with different aperture sizes and various mask shapes, is reported to assess the effectiveness, limitations, and ranges of computationally-admissible applicability of the proposed methods.
