A theoretical analysis of a ridged-circular patch microstrip antenna element excited by a rectangular slot using the cavity model together with an eigenvector expansion, is presented. The approach is based on conserving the reaction at the coupling slot and the ridged positions. The theoretical results are compared with the available experimental results.
