A generalized network formulation using a spherical wave expansion is applied to the analysis of the perturbation induced at the input port of an antenna by nearby scatterers. The antenna is characterized by using the total scattering matrix; the scattering from the obstacles is studied through a physical optics approach, and the interactions are described in terms of radiated spherical waves. The resulting procedure is simple, has a moderate computational cost and can be directly interfaced with measurements. Results show a very good agreement with full-wave simulations.

Abstract

A generalized network formulation using a spherical wave expansion is applied to the analysis of the perturbation induced at the input port of an antenna by nearby scatterers. The antenna is characterized by using the total scattering matrix; the scattering from the obstacles is studied through a physical optics approach, and the interactions are described in terms of radiated spherical waves. The resulting procedure is simple, has a moderate computational cost and can be directly interfaced with measurements. Results show a very good agreement with full-wave simulations.
