Analysis of monopoleantenna with rectangular reflector
Abstract
A simple method for analyzing a monopole antenna with a rectangular reflector, both of which are made of a perfect conductor, is presented. The antenna and the reflector are placed above a perfectly conducting ground plane, and the monopole is fed in the plane by a coaxial line. The method derives from the boundary condition for the tangential component of the electric field vector at the surface of a perfect conductor and on an expression for the electric field vector in terms of the electric and magnetic potentials. The integrodifferential equation thus obtained is solved using the pointmatching method. The surfacecurrent density on the reflector plate is approximated by twovariable polynomials, and simple polynomials are used to approximate the current intensity along the monopole. Special algorithms are developed for computing the integrals involved in the solution.
