A multiple antenna system is described herein that mitigates the negative effects of mutually coupled antennas on the connected transmitters and/or receivers. The antenna system comprises a directional coupler and two or more antennas. The directional coupler comprises multiple communication ports that each connect to corresponding antenna ports. The connection ports each connect to a different transmitter, receiver, or transceiver. A transmission line connects each antenna port to an antenna. The lengths of the transmission lines and the coupling factor of the directional coupler are selected to decouple the communication ports of the directional coupler. More particularly, the coupling factor and the transmission line lengths are selected so that antenna crosstalk signals caused by mutual coupling between the antennas and the coupled signals produced by the directional coupler have the same magnitude but opposite phase at the communication ports of the directional coupler.
