Method for manufacturing an antenna and antenna

Abstract

The embodiment of the present application relates to the technical field of antenna, and discloses a preparation method of an antenna and the antenna, which comprises the following steps: providing a substrate; providing a copper target material, and forming an initial copper layer on the surface of the substrate by physical vapor deposition; providing a chemical immersion plating solution, and immersing the substrate with the initial copper layer in the chemical immersion plating solution to thicken the initial copper layer into a functional copper layer, thereby forming an antenna substrate; providing a first copper protective agent, and immersing the antenna substrate in the first copper protective agent, so that the functional copper layer forms a mechanically wear-resistant layer on the surface; providing a second copper protective agent, and immersing the antenna substrate in the second copper protective agent, so that the functional copper layer forms a chemically passivated layer on the outside of the mechanically wear-resistant layer, thereby forming an antenna. In the above manner, the embodiment of the present application can meet the protection requirements of the antenna copper layer in various different test environments, and improve the long-term weather resistance of the antenna copper layer.
