Abstract

A method of analysis of linear antenna systems for finding the current distributions subjected to a known incident electrical field is proposed. This method is an application of a proposed general procedure for the solution of antenna and scattering problems. The practice of solving an integral equation directly for the unknown current distribution is replaced by that of solving an integral equation for an unknown intermediate function. This intermediate function is shown to be the forcing function of a differential equation whose closed form solution yields the unknown current distribution. This method eliminates the need of applying boundary conditions to the integral operator and these conditions become a property of the differential equation. Numerical results based on the proposed method show a rate of convergence much faster than that of the classical Pocklington’s formulation when simple point matching technique in conjunction with pulse functions is used as a method of solution for the integral equations. The flexibility of the Pocklington’s integral equation is still retained. The method is therefore efficient for computation, yielding small matrix to invert, and providing simple expressions for the radiated fields.
