HIGH ORDER VORTEX ELECTROMAGNETIC WAVE ANTENNA, AND HIGH ORDER VORTEX ELECTROMAGNETIC WAVE GENERATING AND RECEIVING DEVICES AND METHODS

摘要

The present invention relates to the technical field of wireless communication signal processing, and relates in particular to a high order vortex electromagnetic wave antenna, and high order vortex electromagnetic wave generating and receiving devices and methods. The high order vortex electromagnetic wave antenna comprises N uniform circular array antennae, a uniform circular array antenna comprising M antenna array elements axisymmetrically and uniformly distributed on a first circumference having a radius r₁, each antenna array element coinciding with an adjacent antenna array element after rotating around the centre of the first circumference by an angle of 2π/M, the centres of the first circumferences of all the uniform circular array antennae being axisymmetrically and uniformly distributed on a second circumference having a radius r₂, each uniform circular array antenna coinciding with an adjacent uniform circular array antenna after rotating around the centre of the second circumference by an angle of 2π/N. The present invention combines a uniform circular array arrangement structure with a fractal nesting theory, thereby providing a high order vortex electromagnetic wave antenna array element arrangement structure having uniform circular array rotation fractal nesting, and solving the technical problem in the prior art of difficulties with high order vortex electromagnetic wave generating and receiving.
