That is, the aluminum foil 101 is attached to the second surface 103a of the carbon fiber plate. The way that the carbon fiber plate and the aluminum honeycomb plate form the interlayer panel 103 can effectively utilize the advantages of light specific gravity, high strength, high specific rigidity and small thermal deformation of the carbon fiber plate and the aluminum honeycomb plate, so that the formed antenna reflecting plate 100 also has the advantages of light weight and small thermal deformation, can be suitable for different application occasions, and effectively improves the application range of the antenna reflecting plate 100.
In the first embodiment of the present invention, the hot-pressed adhesive 102 is used to adhere between the aluminum foil 101 and the interlayer panel 103, so that the connection tightness and the waterproof effect between the aluminum foil 101 and the interlayer panel 103 can be effectively ensured, the waterproof performance of the antenna reflection plate 100 can be improved, and the application range of the antenna reflection plate 100 can be greatly improved.
