Luneburg lens and manufacturing method therefor, and luneburg lens antenna

Abstract

This application provides a Luneburg lens, a Luneburg lens manufacturing method, and a Luneburg lens antenna. The method includes: preparing a core; covering a surface of the core with a first material and a second material by mixing the first material and the second material in a first ratio to form a first dielectric layer, and processing the first dielectric layer to form a first lens layer; and covering a surface of an (i-1)th lens layer with the first material and the second material by mixing the first material and the second material in an ith ratio to form an ith dielectric layer, and processing the ith dielectric layer to form an ith lens layer, to obtain a Luneburg lens that includes the core and N lens layers covered on the core, where i is any integer ranging from 2 to N in sequence, N is an integer, and N is greater than or equal to 2. According to the method, the first material and the second material may be mixed based on a parameter of each lens layer, to manufacture lens layers layer by layer, thereby simplifying manufacturing steps of the Luneburg lens, and reducing manufacturing process difficulty and manufacturing costs of the Luneburg lens.
