This paper presents an effective design of an array of coupling slots with reflection-canceling walls for uniform excitation of a parallel-plate slot array antenna panel. The coupling slot array is analyzed by Galerkin’s method of moments (MoM) for the fast design by simplifying to use only uniform current on the reflection-canceling walls. It takes only 20 seconds to analyze an array of 14 coupling slots by MoM by a laptop PC having a 16-core Intel Core i7 CPU with 2.60GHz base frequency and 16 GB RAM while it takes 4 hours by HFSS. The values of parameters of each coupling slot by MoM are replaced with those by HFSS having the equal scattering matrix components.
