The plating metal of the horn unit 1, the antenna base 2, the connection base 3 and the connection screw metal plating layer is the same or the potential difference of the two metals is close, so that electrochemical corrosion is prevented, and the connection mode of the antenna base 2 and the connection base 3 can also be welding.
Preferably, the thickness of the metal coating is 2-35 um, so that stable welding connection is convenient to realize.
The scheme aims at preparing the injection mold by a precision machining technology; manufacturing an antenna plastic monomer of the horn monomer 1 by injection molding; and then, electroplating a metal layer on the surface of the horn monomer 1 by an electroplating process. PPS, LCP, PEI, PC + ABS etc. can be selected for use to the array antenna plastic body substrate, and these materials all can be applicable to different environment, can be high temperature resistant again can be anticorrosive. The horn array antenna product manufactured by the scheme has the advantages of good performance consistency, capability of realizing local conduction of the product, light weight, simple process, short processing period and the like. And then, the antenna base 2 is manufactured in a mechanical processing mode. The loudspeaker single body 1 manufactured by injection molding and electroplating is assembled on an antenna base 2 in a welding or screw connection mode to form a large antenna matrix, and then the antenna matrix is connected with a radar or a satellite through an electronic control system to form an air system.
