2‐D field behavior within a metal strip is used to correct the dyadic Green's function for a microstrip structure containing complex‐layered media so that the attenuation constant can be determined. In the x ‐direction, the field is built to display exponential dependence. The strip width is explicitly taken into account, along with the metal thickness and conductivity. New Green's function expressions of the structure are found consistent with a full‐wave electromagnetic code employing zero thickness extent conductors for the guiding metal. Implications for numerical implementation are covered. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 54–60, 2001.
