We are interested in evaluating the coupling between an antenna and a satellite via the only knowledge of the antenna far field pattern. Two approaches, based respectively on a far field approximation or on a multipole expansion of the Green’s kernel, are considered in order to reconstruct the field in the vicinity of the antenna. Some numerical experiments show the improvement of the reconstruction with the multipole techniques.
