Abstract: A transmission device includes: a modulator that selects an Orbital Angular Momentum (OAM) propagation mode among N (N is an integer equal to or greater than 2) OAM propagation modes in accordance with a value of bit data to be transmitted; and a transmitter that transmits a signal of the OAM propagation mode selected by the modulator.

Abstract: A transmission device transmits multiplexed signals obtained by multiplexing signals of N systems corresponding to N Orbital Angular Momentum (OAM) propagation modes. The transmission device includes: an array antenna that includes M antenna elements disposed in a lattice on a plane when viewed from the plane; and a transmitter that multiplies signals obtained by branching each of the signals of N systems into M signals by weighting coefficients of phase shift angles based on angles of the respective M antenna elements with respect to a reference axis passing through a reference point viewed from the reference point on the plane according to the OAM propagation modes, multiplexes the signals of N systems multiplied by the weighting coefficients of the phase shift angles, and transmits signals obtained by the multiplexing from the M antenna elements. M and N are integers equal to or larger than 2.

Abstract: A communication apparatus includes: an antenna including a base having a dome shape, a first antenna element disposed in a first region including a zenith of the base, and one or more second antenna elements disposed in a second region surrounding the first region; and beam forming circuitry that controls, based on position information of a target satellite to communicate with, a beam formation of the first antenna element and the one or more second antenna elements.
