Abstract
An innovative approach is proposed for the synthesis of WAIM structures able to compensate the inter‐element coupling effects limiting the maximum scanning angles of active electronically‐scanned arrays (AESAs). The WAIM is composed by a metasurface represented by a regular grid of microstrip printed unit cells organized according to an hexagonal lattice. Accordingly, the geometrical descriptors of the unit cells are synthesized through a System‐by‐Design (SbD) approach aimed at minimizing the antenna input reflections caused by impedance mismatching when the array is steered. Some numerical results are shown in order to assess the effectiveness of the proposed design methodology.
