发明名称 SPACE DIVISION MULTIPLEXER, AND SPACE DIVISION MULTIPLE CONNECTION DEVICE
摘要 PROBLEM TO BE SOLVED: To increase transmission capacity by space division multiplexing even for an antenna arrangement small in variation of a transmission environment and reduced in transmission capacity and a transmission parameter corresponding to it. SOLUTION: This space division multiplexer includes: a transmitter for transmitting different signals of a plurality of systems from a plurality of transmission antennas to the same space at the same time and with the same frequency; and a receiver for restoring the signals of the plurality of systems from signals received by a plurality of reception antennas. The space division multiplexer is configured such that a substance having specific permittivity different from that of air is arranged, as a phase shifter, in at least one visible transmission route between the plurality of transmission antennas and the plurality of reception antennas.
