Abstract

The invention discloses a 5G radome composite material and a manufacturing method thereof, which relate to the technical field of radomes. The composite material comprises the following raw materials by weight: 60-70 parts of polypropylene, 15-20 parts of glass fiber, 15-20 parts of flash-burnt kaolin and 0.1-3 parts of an auxiliary agent. According to the radome composite material disclosed by the invention, the polypropylene (PP) is used as a base material, the glass fiber is filled to enhance the mechanical property, and on the basis, the flash-burnt kaolin is supplemented to reduce the density and dielectric constant of the material, so that the radome composite material has the advantages of light weight and low dielectric; the problem that in the prior art, radome composite materials are high in weight and dielectric constant is solved. The manufacturing method is simple and low in cost, the density and dielectric constant of the 5G antenna housing material are further reduced on the basis that the mechanical property of the radome composite material manufactured through the manufacturing method is not affected, the purposes of light weight and low dielectric are achieved, and the radome composite material is suitable for being widely popularized.

Description

Technical field [0001] The present invention relates to the field of the antenna cover, in particular a 5G antenna composite material and a method of fabricating it. Background technique [0002] The role of the antenna cover is to protect the antenna system from an external environment (such as wind and snow, sunshine, biology, etc.), extend antenna life, while ensuring transmission of electromagnetic waves, the antenna cover material should meet dielectric properties, mechanical properties , Weather resistance, process, and weight. The most commonly used materials in the 5G antenna cover in the market are mainly glass steel materials. There are three types of glass steel pipe production process: reciprocating fiber winding process, continuous fiber winding process, and centrifugal casting process. [0003] Since the communication base station antennas are basically in the high altitude of the top of the communication base station, in order to facilitate the installation, the co...
