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.
