AI Technical Summary

Technical Problem

Existing Luneberg lenses face challenges in achieving high production efficiency, cost-effectiveness, consistent performance, and lightweight design due to limitations in manufacturing techniques, particularly with 3D printed structures and layered dielectric materials.

Method used

A rolled electromagnetic lens structure using a strip material with a gradually changing dielectric constant in both transverse and longitudinal directions, allowing for multiple lens bodies with varying dielectric constants distributed within a coiled body, and incorporating dielectric materials in predetermined three-dimensional spaces to achieve a more uniform and efficient dielectric distribution.

Benefits of technology

The solution results in improved electromagnetic performance, consistent product quality, higher production efficiency, and the ability to create compact, stable structures that conform to the classical Luneberg lens model, enabling applications in various scenarios.

Abstract

The present invention provides an improved electromagnetic lens, a method for producing it, and a lens antenna. The electromagnetic lens is a rolled body made of a strip material. The dielectric constant of the strip material changes gradually in both the transverse and longitudinal directions of the strip material. Once the strip material is rolled into a coiled body, the dielectric material is distributed over at least a predetermined, artificially defined three-dimensional space called the lens body within the coiled body. A portion of the coiled body other than the lens body is called the non-lens portion. The dielectric constant of the lens body is not less than the dielectric constant of the non-lens portion.The dielectric constant of the lens body decreases progressively in all directions from the inside to the outside of the lens body, and each direction from the inside to the outside of the lens body indicates a direction from a central area of ​​the lens body to a boundary of the lens body. The present invention has the following advantages: 1) good electromagnetic properties; 2) high product consistency; 3) high production efficiency; 4) applicable to a wide range of target sizes; 5) ability to achieve a compact and stable structure; and 6) ability to achieve a single entity with multiple lenses.
