▎ 摘　　要

NOVELTY - 5G antenna cover comprises modified polycarbonate (PC) resin, modified acrylonitrile styrene acrylate (ASA) resin, basalt fiber, low-dielectric glass fiber, filler with hollow structure, toughening modifier, halogen-free flame retardant, weather resistance agent, anti-aging stabilizer, UV absorber and antibacterial agent, where the low-dielectric glass fiber is flexible low-dielectric glass fiber. USE - The 5G antenna cover is used in a mobile communication system. ADVANTAGE - The 5G antenna cover achieves the technical effect of improving dielectric properties, mechanical strength and weather resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the 5G antenna cover comprising (a) using basalt fiber and low-dielectric glass fiber as raw materials, and weaving into a three-dimensional hollow composite fabric structure through a three-dimensional multi-beam rapier loom, (b) mixing the modified PC resin and the modified ASA resin, and adding additives during the mixing process to form a resin for impregnation, (c) placing the three-dimensional hollow composite fabric structure into an impregnation tank, leaving the resin to fully impregnate the three-dimensional hollow composite fabric structure, and solidifying and forming the antenna cover.
