Abstract

The invention discloses a three-dimensional OAM antenna architecture implementation method for enhancing indoor signal coverage. The method comprises the following steps of: arranging antenna array elements on a vertex of a three-dimensional graph according to a preset arrangement rule to form a geometrical relationship between the antenna array elements; dividing the antenna array elements into a plurality of sub-arrays according to the geometrical relationship between the antenna array elements; and uniformly performing phase excitation on the antenna array elements, so as to make the plurality of sub-arrays respectively generate vortex electromagnetic waves in different modes, and make each sub-array radiate in one direction. According to the method and the system disclosed by the invention, signal coverage in multiple directions can be realized, and the OAM signal coverage range in an indoor scene is effectively expanded.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a method and system for implementing a three-dimensional OAM antenna architecture for enhancing indoor signal coverage. Background technique [0002] Orbital Angular Momentum (OAM) is a new communication multiplexing dimension independent of traditional modulation degrees of freedom such as time and frequency. In theory, it has an infinite-dimensional Hilbert space and has the potential to improve system capacity and spectrum utilization. Electromagnetic waves carrying orbital angular momentum are called vortex electromagnetic waves. The vortex electromagnetic wave has the characteristics of unique helical phase and hollow strength structure. The generation of vortex electromagnetic waves is the basis of building an OAM system, and the efficient and flexible generation of multiple modal vortex electromagnetic waves is the key to the practical application of orbital angu...
