The method of combining wedge diffraction solutions for the analysis of an axial TEM-mode slot is extended here for an arbitrary aperture antenna in a finite size ground plane. The new approach, however, considers superposition of boundary-value and wedge-diffraction solutions on the same antenna. The boundary-value solution (primary pattern) considers the pattern component when the aperture is in an infinite ground plane, and the diffraction solution (secondary pattern) considers the contribution to the pattern from the edges of the finite ground plane.
