Multiple-antenna-port and multiple-user-port antenna tuners

     We have investigated new multiple-antenna-port and multiple-user-port (MAPMUP) antenna tuners, which are intended to be inserted between several antennas and a radio device using the antennas simultaneously in the same frequency band. The radio device is typically a receiver, a transmitter, or a transceiver for MIMO radio communication. Some of our results are presented in the following articles.
