Abstract
An OAM mode-multiplexing transmitting apparatus includes an OAM transmitting processing unit, a phase adjustment unit, a transmitting radio unit, a UCA (Uniform Circular Array) antenna, and a control unit (control apparatus). The UCA antenna includes a plurality of transmitting antenna elements. In the control apparatus, an acquisition unit acquires 'information corresponding to a transmitting-side axis misalignment'. A beam control unit controls a beam of the UCA antenna by controlling phases of N OAM mode-multiplexing signals based on the acquired “information corresponding to the transmitting-side axis misalignment”.
