Plane wave excitation of the parallel plate-loaded slot antenna

Two numerical solutions are given for an integrodifferential equation governing the electric field in the aperture of a parallel-plate, waveguide-loaded, slot antenna excited by an obliquely incident plane wave. Resultant aperture field distributions obtained via Galerkin's method with a basis of edge-condition weighted Chebyshev polynomials are compared with the results from pulse expansion with point matching. Efficient algorithms are obtained for the elements of the reduced matrix equations for both moment methods.<
