“…For axially corrugated horns with wider flare angles and larger apertures, different full‐wave numerical simulation methods were used for performance prediction, which are generally time consuming [ Kim et al ., ; Chang and Hanlin , ]. As introduced in Dubrovka and Stepanenko [] and James and Thomas [], horns with axial slots are represented as a number of separate modules. Each module consists of a junction between a composite waveguide, which comprises a circular waveguide and a short‐circuited coaxial waveguide, and a circular waveguide with a larger radius.…”

“…Hence, an efficient numerical algorithm is needed to facilitate the design and optimization procedures. Calculation based on modal‐matching method similar to Dubrovka and Stepanenko [] is carried out here to theoretically investigate the axially corrugated dielectric‐rod‐loaded horn. Analytic expressions of power‐coupling integrals between dielectric‐rod‐loaded circular waveguides, hollow circular waveguides, or coaxial waveguides are also presented in order to accelerate the calculation.…”

An efficient design procedure based on modal‐matching method for axially corrugated dielectric‐rod‐loaded horns of complicated geometries is proposed in this paper. Calculation of the generalized scattering matrix of individual module, which is obtained by dividing the complex horn into simple sections, is carried out. Analytic expressions of power‐coupling integrals between different kinds of waveguides are presented, including those derived initially, which greatly shorten the calculation time. Techniques including the field equivalence principle and the spherical mode expansion are further implemented for radiation pattern prediction. A rexolite‐loaded axially corrugated horn antenna is finally investigated as a numerical experiment, with the frequency range of 17–33 GHz. The results obtained by our method and by commercial full‐wave simulation software are in excellent agreement, but our method is more efficient.
