• An accurate full‐wave simulation of the resonant behavior of microstrip antennas is very important, but too time consuming. This paper presents an efficient method to characterize the resonant behavior of microstrip antennas in multilayered media using the method of moments (MoM) combined with interpolation/extrapolation techniques. Polynomial and rational interpolations are implemented and compared to each other. Also, the present method uses the adaptive sampling algorithm to maximize the information provided by each new sample in a 1‐D or 2‐D interpolation/extrapolation. By this approach, the resonant frequencies with respect to both physical dimensions and dielectric constants can be extracted, with minimum sampling points needed. The numerical experiments for several microstrip antennas show the efficiency and accuracy of the present method. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 342–346, 2001.
