Method of moments analysis of arrays of cylindrical microstrip antennas with superstrate

This study presents a full-wave solution for arrays of cylindrical-rectangular microstrip antennas, with superstrate. It uses the method of moments (MoM), with full-domain basis functions. The same set of functions is used as testing-functions resulting in a Galerkin procedure. A numerical procedure is presented allowing an efficient and numerically stable evaluation of the elements of the MoM linear system. Results for input impedance are compared to those using HFSS for a flush-mounted geometry. Results for radiation pattern, mutual impedance, and coupling coefficient $S_{12}$S12 are also presented. And the effects of the superstrate on those parameters are evaluated.
