The mode‐matching method (MMM) is applied to analyze the propagation characteristics of quadruple‐ridged square waveguides. Numerical results for the eigenvalues and characteristic impedance are presented and compared with available data in the literature. Good agreement is observed. Design examples are presented for the quadruple‐ridged square waveguides operating at 2–18 GHz and 18–40 GHz, respectively. These two examples will be used in the design of dual‐polarized broad‐band horn antennas. © 2005 Wiley Periodicals, Inc.
