Problems solved by technology

However, since most of the existing metamaterials are prepared using the PCB process, they are only suitable for processing flat metamaterials, and because the radome needs to be made into various shapes for various purposes, it cannot be realized with the existing process

Abstract

The invention relates to a manufacturing method for a metamaterial antenna housing. The manufacturing method for the metamaterial antenna housing comprises the following of steps a, manufacturing a flexible thin metamaterial membrane provided with a plurality of artificial microstructures, b, manufacturing a die, wherein the die comprises a female die and a male die, the female die and the male die are mutually separated and can carry out relative movement to be combined in a closed mode, a concave cavity is formed by the female die, and a mold core which can be placed into the concave cavity is arranged on the male die in a protruding mode, c, placing the flexible thin metamaterial membrane in the concave cavity, attaching the flexible thin metamaterial membrane to the cavity wall, d, carrying out die assembly, placing the mold core of the male die into the concave cavity of the female die to form a die cavity, injecting a molten resin solution into the die cavity, and e, carrying out die disassembly after the resin solution is cooled and solidifies, and obtaining the metamaterial antenna housing which is provided with the artificial microstructures and is identical with the die cavity in shape. According to the manufacturing method for the metamaterial antenna housing, die cavities with different shapes can be manufactured to obtain various needed metamaterial antenna housings, and the artificial microstructures can be well arranged on the metamaterial antenna housing in a conformal mode.

Description

technical field [0001] The present invention relates to a radome, and more particularly, to a method of manufacturing a radome. Background technique [0002] Now the radome is widely used as a protective part of the antenna, and with the development of various aspects of application, higher requirements are put forward for the electrical and mechanical properties of the radome. In terms of electrical performance, at present, people often use materials such as glass fiber reinforced plastics with low dielectric constant and loss and high mechanical strength to make radome, but the electrical performance of radome made of these materials is poor. As a new type of wave-transparent material, metamaterials are gradually being paid attention to by researchers and used to make radomes. [0003] Metamaterials are artificial composite structural materials with extraordinary physical properties that natural materials do not have. At present, people periodically arrange artificial mi...
