First Claim
1. A communication system that comprises a transmit antenna, a radio frequency (RF) phase shifting module, an RF combiner, a first receive antenna and a second receive antenna;
- wherein the first and second receive antennas are located at a same distance from the transmit antenna;
wherein the first and second receive antennas are arranged to receive first and second leakage signals resulting from a transmission of RF radiation by the transmit antenna;
wherein the RF phase shifting module is configured to receive signals from the first and second receive antennas, to phase shift signals from at least one of first and second receive antennas to provide intermediate RF signals;
wherein the phase shift caused by the RF phase shifting module introduces a destructive phase shift between the first and second leakage signals;
wherein the RF combiner is configured to add the intermediate RF signals to provide combined RF signals.
