Passive characterization of the couplings within a multi-antenna system through noise correlation
Résumé
This communication deals with a technique to passively retrieve the couplings between several antennas. The mutual-impedance of coupled antennas are deduced from field correlations in a reverberation chamber (RC). It is experimentally shown that the impedance matrix between 2 slot antennas or 3
horn antennas are reconstructed with good accuracy whatever the antenna properties. The accuracy is quantified with respect to the distance between the antennas
