Problems solved by technology

[0005] The production of wrapped structures usually requires the use of molds. If there are too many layers, the process is too complicated and the cost is high, and the performance consistency of different individuals is usually poor
[0006] Although the number of layered layers of the rolling structure is easy to make more layers, the existing technology can only make it into a cylinder or an ellipse cylinder instead of a sphere in the classical model, and in the middle of the cylinder and the ellipse cylinder The axial direction does not conform to the theory of the classical model, which greatly reduces its performance effect, so that it cannot meet the performance requirements in many scenarios
[0007] Holes are usually made by 3D printing, and the 3D printed structures are usually a single hot-melt material. The hot-melt materials suitable for 3D printing are either inappropriate in dielectric constant or low in density. , when faced with the production of large-scale lenses, its weight is considerable so that it causes various difficulties in installation and use

Abstract

The invention provides a better electromagnetic wave lens, a production method and a lens antenna. The electromagnetic wave lens is a rolled body formed by rolling a strip-shaped material; dielectric constants of a dielectric materials are gradually changed in the transverse direction and the longitudinal direction of the strip-shaped material; after the strip-shaped material is rolled into the rolled body, the dielectric material is distributed in at least one predetermined three-dimensional space range in the rolled body, and the rolled body is called a lens body; the part, except the lens body, of the rolled body is called as a non-lens part; the dielectric constant in the lens body is not lower than that of the non-lens part; in the lens body, dielectric constants in all directions from inside to outside are lower and lower, and the directions from inside to outside refer to the direction from the central area of the lens body to the boundary of the lens body. The invention has the advantages of good electromagnetic property, high product consistency, high production efficiency, suitability for wide target sizes, compact and stable structure, and realization of single entity and multiple lenses.

Description

technical field [0001] The invention relates to the field of communication equipment production, more specifically, to an electromagnetic wave lens, a production method of the electromagnetic wave lens and an electromagnetic wave lens antenna. Background technique [0002] The Luneberg lens was proposed by RK Luneberg in 1944 based on the geometrical optics method. It is used as an antenna and scatterer, mainly used in fast scanning systems, satellite communication systems, automotive anti-collision radars, radar reflectors and other fields. [0003] The classic model of Lunberg lens is: from the center of the sphere to the outer diameter of the Lunberg lens, the dielectric constant should change continuously from 2 to 1 in accordance with certain mathematical laws. However, such an ideal structure does not exist in nature, so in practical design, a layered structure with step-change dielectric constant is often used to approximate the theoretical structure. [0004] In the...
