Antenna pattern in a multipath environment emulated in a reverberating chamber

This paper presents a first approach to obtain the radiation pattern of an antenna in a multipath chaotic environment where both scattered and direct component were considered. Measurements accomplished in a reverberating chamber (RC), with the two antennas faced each other, exploit the rice factor, K, to trace the pattern of a receiving antenna in very hard electromagnetic conditions. However, given the reciprocity of an RC, we indifferently talk of radiation and reception pattern. Experiments undertaken over a large set of measurements accomplished at the RC of the Università di Napoli Parthenope, formerly Istituto Universitario Navale (IUN), confirm the effectiveness of the proposed method from an operational point of view.
