Provided in the present disclosure are a grating structure, a preparation method thereof and a display device. The preparation method of the grating structure includes: forming a plurality of first convex structures arranged in a first direction; and forming a first rubber material at least covering the plurality of first convex structures, and forming the grating structure including a plurality of second convex structures by using convex structures including the first convex structures and the first rubber material, wherein a surface of the first rubber material facing away from the first convex structures is a flat surface, and the convex structures including the first convex structures and the first rubber material are in one-to-one correspondence with the second convex structures, shapes of cross sections of the second convex structures in the first direction are triangles, and the second convex structures have at least one inclined flat surface.

Grating structure, preparation method thereof and display device

An antenna includes a substrate and a radiator fixed to the substrate. A thermal protection system for the antenna includes a thermal protection sheet body opposite to and spaced from the antenna, where the thermal protection sheet body separates the antenna from an external heat source; and a groove body formed in the thermal protection sheet body, where the radiator generates an antenna near field toward the outside, and an inner wall of the groove body is adapted to an edge of the antenna near field to reduce the deterioration of antenna performance caused by the thermal protection sheet body. The overall electrical performance and the thermal protection performance of the thermal protection system can be well balanced by decreasing the thickness of a middle area of the thermal protection system or by etching a groove in a certain shape in the thermal protection system.
