Abstract
In this work, the design of wideband wide-angle impedance matching (WAIM) structures is proposed for waveguide-fed planar phased arrays. An innovative System-by-Design (SbD) approach is exploited to determine the geometrical descriptors of the WAIM, which is composed by a metasurface of regularly-arranged microstrip printed unit cells. The proposed solution technique is based on the combination of elementary functional blocks aimed at (i) exploring the search space, (ii) analyzing the resulting metasurface structure to deduce the equivalent permittivity/permeability tensors, (iii) computing the phased array response, and (iv) linking the obtained result with the problem constraints and objectives to determine the associated cost function. Some numerical results are shown in order to assess the effectiveness of the SbD-based design strategy.
