Analysis of monopole-antenna 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 integro-differential equation thus obtained is solved using the point-matching method. The surface-current density on the reflector plate is approximated by two-variable 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.
