1. A reflective antenna apparatus, comprising:

  • a feeder which receives an electromagnetic wave from a transmitter and distributes the electromagnetic wave to the antenna apparatus;

    a sub reflector which has a step formed to generate an orbital angular momentum (OAM) mode electromagnetic wave; and

    a main reflector which has a step formed to generate the same electromagnetic wave as the OAM mode generated by the sub reflector and cancels the OAM mode electromagnetic wave generated by the sub reflector and an OAM mode electromagnetic wave generated by the main reflector to radiate the electromagnetic waves to a far field.
