Efficient analysis of SIW-based antenna geometries through a rigorous MoM mode-matching approach
Résumé
An efficient full-wave code handling surface-integrated-waveguide based antennas is presented, implementing a hybrid method-of moments and mode-matching approach. Entire-domain basis functions are chosen to minimize the number of unknowns, and an efficient computation of Green functions for large radial distances is granted by means of a radial-transmission-line representation. The mode matching relies on an efficient cylindrical vector wave function expansion of the field. Both the accuracy and the efficiency are largely superior with respect to general-purpose commercial solvers.
