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. date: 2017 publisher: ELEDIA Research Center - University of Trento referencetext: G.
