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

Embodiment Construction

[0031] Such as Figure 1 to Figure 3 Shown is a preferred embodiment of the manufacturing method of the metamaterial radome of the present invention. The preferred embodiment includes the following steps:

[0032] a. Make a first mold 30 , the first mold 30 has a cavity 33 and a core 37 placed in the cavity 33 , thereby forming a cavity 39 .

[0033] b. Injecting molten first plastic 40 into the mold cavity 39 .

[0034] c. After the first plastic 40 is cooled and solidified, the mold is opened to produce a cover 42 .

[0035] d, make a second mold 50, the second mold 50 has the same cavity 53 as the cavity 33 of the first mold 30 and a core 57 that can be placed in the cavity 53, the mold The core 57 is smaller than the core 37 of said first mold 30 .

[0036] e. Put the cover body 42 into the concave cavity 53 of the second mold 50 , and paste a metamaterial thin film 60 with a metamaterial artificial microstructure on the inner surface of the cover body 42 .

[0037] f...

Abstract

The invention relates to a manufacturing method of a metamaterial antenna housing. The method comprises the following steps of: manufacturing a first mold, wherein the first mold comprises a concave cavity and a mold core arranged in the concave cavity, which form a mold cavity; injecting molten first plastics in the mold cavity, cooling and solidifying to obtain a housing body; manufacturing a second mold, wherein the second mold comprises a concave cavity and a mold core, the concave cavity is same as that of the first mold, and the mold core can be arranged in the concave cavity, and the mold core of the second mold is smaller than that of the first mold; placing the housing body in the concave cavity of the second mold, and pasting a metamaterial film with a artificial metamaterial microstructures on the inner surface of the housing body; closing the second mold, placing the mold core in the concave cavity to form a mold cavity; and injecting the molten second plastics in the mold cavity of the second mold, cooling and solidifying, then opening the mold, thus, obtaining the metamaterial antenna housing with the artificial metamaterial microstructures, wherein the surface shape of the metamaterial antenna housing is same as the shape of the mold cavity of the first mold.

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 metamaterial ...
