Abstract

A method is presented that solves the antenna analysis problem with consideration of the interaction between the feed signals and the currents on the antenna surfaces. The method solves the problem exactly by obtaining an antenna impedance matrix that describes the electrical characteristics of the antenna surfaces and feed network. This matrix consists of the standard method of moments (MM) impedance matrix along with the feed scattering matrix and continuity (joining) equations that relate the MM expansion coefficients to the feed signals. Thus, a solution of this matrix equation provides a complete description of the antenna for a specified excitation. This complete matrix solution of antenna analysis includes all the interactions between feed and aperture, as well as the finite array and ground plane edge effects.<>
