Problems solved by technology

[0004] However, since the feed antenna is located directly in front of the array, the feed will block the reflected vortex waves, resulting in a decrease in the purity of the generated vortex waves
And the generated vortex field has no converging function, and the field strength is weak

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0028] like figure 1 Shown, a kind of biased vortex wave generator with converging function, it comprises reflect array and the antenna feed source that is positioned at the non-facing area in front of the reflect array; The position radiates spherical electromagnetic waves, and the reflection array is used to convert the spherical waves incident on the antenna feed into converging vortex waves by means of phase compensation, and emit and propagate along the direction perpendicular to the reflection array.

[0029] The conversion of the incident spherical wave from the antenna feed into a converging vortex wave by means of phase compensation includes performing vortex wave phase compensation on the incident spherical electromagnetic wave by the reflective array to realize the...

Abstract

The invention relates to an offset vortex wave generator with a converging function. The offset vortex wave generator comprises a reflective array and an antenna feed source located in a non-oppositearea in front of the reflection array, wherein the antenna feed source is used for radiating spherical electromagnetic waves to the geometric center of the reflective array, and the reflective array is used for converting the spherical waves incident from the antenna feed source into converged vortex waves in a phase compensation mode and transmitting and propagating the converged vortex waves inthe direction perpendicular to the reflective array. The offset vortex wave generator has the advantages that incident spherical electromagnetic waves are subjected to phase compensation through the reflective array, so that the emission of the converged vortex waves with a converging function is realized; the antenna feed source is arranged on the side of the reflective array, so that the shielding of the antenna feed source on the radiating electromagnetic waves is avoided, and meanwhile, the influence of the radiating electromagnetic waves on the antenna feed source is also avoided; and thefocus F formed in front of the reflective array can achieve the effects of converging the generated vortex waves and enhancing the electric field, and the overall planar array structure is simple.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a bias-feed vortex wave generator with a converging function. Background technique [0002] In the field of communication, there are four basic ways of multiplexing: frequency division multiplexing, time division multiplexing, code division multiplexing and space division multiplexing. Improve rapidly. But even so, with the gradual increase in the number of mobile terminals, information is showing an explosive development trend. In order to meet the ever-increasing mobile data service needs of users, the research on a new generation of wireless mobile communication technology with higher speed, high efficiency and intelligence is imminent. , is a brand-new physical mechanism that may further increase system capacity and spectrum utilization from a new dimension. Electromagnetic waves carrying orbital angular momentum are called vortex waves. The corresponding v...
