The analysis of radiation and scattering from a multiregion quasiplanar structure using the conventional method of moments (MoM) is computationally expensive. To circumvent this difficulty, a computational scheme that supplements the classical MoM with the steepest descent fast‐multipole algorithm is presented in this paper. This proposed methodology is particularly well suited to the analysis of finite microstrip antenna arrays. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 23: 306–310, 1999.
