摘要

A new multilevel Green's function interpolation method (MLGFIM) used for the analysis of microstrip antenna arrays is presented. Dyadic Green's function for a layered medium is used in this method as the kernel to efficiently reduce the number of unknowns. Interpolation of this type of Green's function is then implemented by radial basis functions (RBFs). The interpolation accuracies using Lagrange and RBF interpolations are compared. A numerical example of a 30 by 30 microstrip patch array is given to validate the accuracy and efficiency of the proposed method.
