Enhancement of Efficiency of Integral Equation Solutions of Antennas by Incorporation of Network Principles—Part I

A method is presented for enhancing the efficiency of integral equation solutions for antennas by reducing the number of coupled integral equations to be solved in a method of moments analysis. This method is applied to the accurate modeling of the feed of a simple cylindrical monopole antenna. A microwave network is developed to replace the effects of coupled fields due to one of the unknowns. Computed reflection coefficient values are shown to agree well with values measured on laboratory models and a method of moments solution not incorporating network principles.
