However, in traditional antenna design, the antenna vibrator and other components are assembled separately on the antenna substrate, and then the antenna vibrator and other components are connected to form an antenna through wiring, which can easily lead to unstable consistency of antenna products. Summary of the invention

[0005] The feed metal line, feed floor, feed network unit and radiation layer unit are designed as metal plating, which are integrated on the antenna mainboard. The antenna mainboard is formed by integral injection molding of the antenna substrate, radiation substrate and feed substrate. In short, the antenna vibrator structure first forms an integral injection-molded body, and then copper or other metals are plated at the corresponding positions of the injection-molded body to form a metal circuit part. In this way, such an antenna vibrator structure not only reduces the number of components that need to be manufactured and assembled separately, but also reduces the assembly complexity of the overall structure of the antenna, making the consistency of the antenna product more stable, and also making broadband antenna vibrators.
[0006] In an optional embodiment, the radiation layer unit includes a plurality of radiators formed by laser engraving, and the plurality of radiators form a preset radiation pattern on the surface of the radiation substrate.

[0009] There is a feed connection hole on the radiation substrate. When copper or other metals are plated at the corresponding position of the antenna mainboard to form a metal circuit part, liquid metal flows into the feed connection hole to form a feed connection column.

DETAILED DESCRIPTION
[0023] The present invention is described in detail below in conjunction with specific embodiments.
[0024] like Figure 1-Figure 5 As shown, the embodiment of the present application provides an antenna vibrator, including an antenna mainboard 100, a feed line unit 200, a feed network unit 300 and a radiation layer unit 400, the antenna mainboard 100 includes an antenna substrate 101, a feed substrate 102 and a radiation substrate 105, as shown in FIG. Figure 4As shown, the feed line unit 200 is provided with a feed metal line 201 and a feed floor 204, the feed metal line 201 and the feed floor 204 are respectively plated on the feed substrate 102, the feed metal line 201 is connected to the feed network unit 300, the feed floor 204 is connected to the radiation layer unit 400, the feed network unit 300 is plated on the antenna substrate 101, the radiation layer unit 400 is plated on the radiation substrate 105, and the antenna substrate 101, the radiation substrate 105 and the feed substrate 102 are integrally injection molded to form the antenna mainboard 100.
[0025] It should be noted that the feed metal line 201, feed floor 204, feed network unit 300 and radiation layer unit 400 are designed as metal plating layers, which are integrated on the antenna mainboard 100. The antenna mainboard 100 is formed by integral injection molding of the antenna substrate 101, the radiation substrate 105 and the feed substrate 102. In short, the antenna vibrator structure of the embodiment of the present application first forms an integral injection molded body, such as can be made into a desired shape by various molding processes such as injection molding and extrusion, and then copper or other metals are plated at the corresponding positions of the injection molded body to form a metal circuit part, such as using a highly conductive metal material (such as copper, silver or aluminum) through evaporation deposition, sputtering or electroplating to form a metal conductive layer on the injection molded body. Such an antenna vibrator structure not only reduces the number of components that need to be manufactured and assembled separately, but also reduces the assembly complexity of the overall structure of the antenna, making the consistency of the antenna product more stable.
[0026] like Figure 1 and Figure 2 As shown, the radiation layer unit 400 includes a plurality of radiators 401 formed by laser engraving, and the plurality of radiators 401 form a preset radiation pattern on the surface of the radiation substrate 105. The radiator 401 is a metal radiation layer of the antenna vibrator structure that transmits or receives electromagnetic waves. The radiation pattern is a graphic used to describe the ability of the antenna to radiate or receive electromagnetic waves in different directions. The designed radiation pattern can work in multiple frequency bands. By optimizing the design of the antenna and the selection of materials, the bandwidth of the antenna can be improved so that it can maintain good radiation characteristics in a wider frequency range to meet different communication needs. In the embodiment of the present application, copper or other metal is plated on the surface of the radiation substrate 105 to form a coating, and then a radiation pattern is engraved by laser engraving. The radiation pattern includes a plurality of radiators 401, or it can be said that the radiation pattern is formed by a combination of a plurality of radiators 401. The use of laser engraving to make the radiation layer can perform very fine processing on the surface of the radiation substrate 105, thereby improving the product consistency of the antenna.
[0027] like Figure 1 , 2As shown in Figures 3 and 4, the feed line unit 200 includes a feed connection layer 207 connected to the feed floor 204 and a feed connection column (not shown) connected to the feed connection layer 207.

The feed connection column penetrates the radiation substrate 105 to respectively connect the feed connection layer 207 and the radiation layer unit 400. The radiation substrate 105 is provided with a feed connection hole at a corresponding position. When the antenna main board 100 is plated with copper or other metal, liquid metal flows into the feed connection hole to form a feed connection column, that is, the feed connection column can penetrate both sides of the radiation substrate 105, so that the feed connection layer 207 and the radiation layer unit 400 are connected and conducted through the feed connection column, which reduces wiring and manual assembly steps and helps to improve product consistency.
[0028] like Figure 4 and Figure 5 The feed substrate 102 includes a first support substrate 103 and a second support substrate 104 which are integrally injection molded. The first support substrate 103 and the second support substrate 104 are arranged in a cross shape. The feed substrate 102 is arranged in a cross shape. The feed line unit 200 is designed with polarity symmetry on the feed substrate 102 to ensure that the electrical characteristics (such as impedance, radiation mode, etc.) in all directions are the same or similar, which is conducive to improving product consistency. Specifically, the feed metal line 201 includes a first metal line 202, and the feed floor 204 includes a first metal sheet 205. The first metal line 202 is located on one side of the first support substrate 103, such as Figure 4 As shown, the first metal sheet 205 is designed with two pieces, and the first metal sheet 205 is located on the other side of the first supporting substrate 103. The feeding metal line 201 includes a second metal line 203, and the feeding substrate 204 includes a second metal sheet 206. The second metal line 203 is located on one side of the second supporting substrate 104. Figure 4 As shown, the second metal sheet 206 is designed with two pieces, and the second metal sheet 206 is located on the other side of the second supporting substrate 104. The feeding metal line 201 and the feeding floor 204 are orthogonally polarized on the cross-shaped feeding substrate 102, which is conducive to improving product consistency.
[0029] like Figure 6 As shown, the present application also provides an antenna, including a plurality of antenna elements, each antenna element includes an antenna mainboard 100, a feed line unit 200, a feed network unit 300 and a radiation layer unit 400, the antenna mainboard 100 includes an antenna substrate 101, a feed substrate 102 and a radiation substrate 105, combined with the above Figure 1-Figure 5The feed line unit 200 is provided with a feed metal line 201 and a feed floor 204, the feed metal line 201 and the feed floor 204 are respectively plated on the feed substrate 102, the feed metal line 201 is connected to the feed network unit 300, the feed floor 204 is connected to the radiation layer unit 400, the feed network unit 300 is plated on the antenna substrate 101, the radiation layer unit 400 is plated on the radiation substrate 105, the antenna substrate 101, the radiation substrate 105 and the feed substrate 102 are integrally injection molded to form the antenna main board 100. Figure 6 As shown, the antenna mainboard 100 of multiple antenna elements can be integrally injection molded, the feed network units 300 of the multiple antenna elements are connected, the feed metal line 201, the feed floor 204, the feed network unit 300 and the radiation layer unit 400 are designed as metal plating layers, which are all integrated on the antenna mainboard 100, and the antenna mainboard 100 is integrally injection molded by the antenna substrate 101, the radiation substrate 105 and the feed substrate 102. In short, the antenna element structure first forms an integral injection molded body, and then copper or other metals are plated at the corresponding positions of the injection molded body to form a metal circuit part. In this way, such an antenna element structure not only reduces the number of components that need to be manufactured and assembled separately, but also reduces the assembly complexity of the overall structure of the antenna, making the consistency of the antenna product more stable.
