As shown in fig. 1 and 2, a horn array antenna includes a horn unit 1 and an antenna base 2, wherein a small opening end of the horn unit 1 is provided with a connecting base 3, the horn unit 1 is vertically arranged on the connecting base 3, the connecting base 3 is provided with a connecting screw hole and is fixed on the antenna base 2 through a connecting screw, and the antenna base 2 is provided with a plurality of horn units 1 to form a horn array antenna; the loudspeaker single body 1 and the connecting base 3 are made of plastic materials, and the surfaces of the loudspeaker single body 1 and the connecting base 3 are provided with electroplated metal layers; the antenna base 2 is made of plastic, an electroplating metal layer is arranged on the surface of the antenna base 2, and an electroplating metal layer is arranged on the surface of the connecting screw.
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.
