Abstract

We are interested in deducing the coupling between an antenna and some surrounding structures via the only knowledge of the antenna far-field measured in an anechoic room. A new approach based on a multipole expansion of the Green´s kernel is considered to evaluate the field in the vicinity of the antenna. Some numerical experiments illustrate the efficiency of the multipole techniques compared to the physical optic approach.
