Abstract :
The magnetic-wall cavity modes are used as basis functions for the full-wave analysis of an annular patch, proximity coupled to a feeding microstrip line, carried out with the spectral-domain version of the method of moments. Particular emphasis is given to the effect of the commonly adopted exclusion of TE modes. An efficient, time saving technique for the evaluation of the reaction integrals is also presented.
