  • High order vortex wave antenna and device and method for generating and receiving high order vortex wave
    Patent number: 10498045
    Abstract: A high order vortex wave antenna includes N uniform circle array antennas. The uniform circle array antenna includes M antenna array elements distributed uniformly in axial symmetry on a first circle with a radius of r1. Each antenna array element coincides with an adjacent element after rotating around a center of the first circle by an angle of 2?/M Centers of the first circles of all uniform circle array antennas are distributed uniformly in axial symmetry on a second circle with a radius of r2. Each uniform circle array antenna coincides with an adjacent uniform circle array antenna after rotating around a center of the second circle by an angle of 2?/N.
