%T Innovative Synthesis of WAIM Layers for Waveguide‐Fed Planar Phased Arrays
%U http://www.eledia.org/students-reports/747/
%X This work deals with the design of wide-angle impedance matching (WAIM) layers aimed at mitigating reflection issues arising in waveguide-fed planar phased arrays. The synthesis problem is formulated within the System-by-Design (SbD) framework, by minimizing the antenna input reflections caused by impedance mismatching when the array is steered through the optimization of the geometrical descriptors of the WAIM unit cells. Some numerical results are shown in order to assess the effectiveness of the proposed synthesis strategy.
