This contribution shows that the FDTD technique is an effective design tool for producing dual‐polarized circular stacked patch antennas. Computational requirements may be minimized by careful modeling of the coaxial feedline, including the use of mode filtering at the aperture plane of the antenna. The design process for an antenna at a frequency of 4.7 GHz is described, and results obtained for return loss and coupling between the two ports of the antenna and radiation patterns are presented. These are in very good agreement with experimental data. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 223–226, 2001.
