Radiation and scattering by wire antenna structures near a rectangular plate reflector

A theoretical-numerical technique is developed to solve for the current distributions and, hence, for the field patterns of perfectly conducting antenna structures composed of a rectangular plate and straight wires arranged in any fashion. Scattering by thin plates can also be solved. Electrical field integral equations of the Pocklington´s type are formulated. These equations are solved by the Bubnov-Galerkin projective method with Lagrangian interpolation polynomials as basis functions. Numerical results are shown to give good agreement with those obtained by other methods.
