In order to make the appearance of electronic products with antennas more aesthetically pleasing, curved antennas that fit into the antenna part of electronic products have been rapidly developed. The conventional method of manufacturing curved antennas is to manufacture individual planar antenna plates and then install them onto the curved antenna part of the product by splicing them together. Curved antennas manufactured in this way will have gaps at the junctions of the individual planar antenna plates on the surface of the curved antenna of the electronic product, resulting in lower stability and safety issues during the use of the curved antenna. Summary of the Invention

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0043] In one embodiment, a method such as Figure 1 The method for fabricating the curved antenna shown includes the following steps:

[0044] Step S100: Fabricate at least one structural tooling for pressing together each planar antenna plate.

[0045] In this embodiment, the curved antenna is installed at the curved antenna mounting position of the relevant electronic product. There are two cases for the curvature of the surface at the mounting position: the first is that the curvature of the surface is the same at all points of the mounting position, and the second is that there are multiple curvatures of the surface at all points of the mounting position.

[0046] For the first scenario, a three-dimensional model of the curved antenna at the installation location of the electronic product can be created using laser scanning, and the curvature of the curved antenna at the installation location of the electronic product can be calculated based on the three-dimensional model.

[0047] Based on the surface curvature obtained above, construct as follows: Figure 2-1 The lower structural component 1 of the structural component tooling shown has an upper surface that is a convex structure 11. The curvature of the convex structure 11 is determined based on the curvature of the curved antenna at the installation position of the electronic product obtained above.

[0048] After fabricating the lower structural component 1 of the structural component fixture, fabricate as follows: Figure 2-2 The upper structural component 2 shown has a concave structure 21 on its lower surface. The curvature of the concave structure 21 is determined based on the curvature of the curved antenna at the installation position of the electronic product obtained above. Since there is only one type of curvature in this case, only one set of structural component tooling needs to be made.

[0049] For the second scenario, a three-dimensional model of the curved antenna at the installation location of the electronic product can be established using laser scanning. Based on the three-dimensional model, the curvature of each segment of the curved antenna at the installation location of the electronic product can be calculated. Based on the number of segments, N surface curvatures can be obtained, where N is an integer greater than 1.

[0050] For each surface curvature, corresponding structural fixtures can be made according to the method in the first case, resulting in N structural fixtures.

[0051] Step S200: Press each planar antenna plate together using structural tooling to form a curved antenna plate with a set curvature.

[0052] In this embodiment, after the structural component tooling is fabricated, it is necessary to fabricate the following: Figure 2-3 The planar antenna board 3 shown includes a first dielectric layer 31, a first circuit layer 32, and a second circuit layer 33. The first circuit layer 32 is located on the first dielectric layer 31, and the second circuit layer 33 is located on the other side of the first dielectric layer 31. The first dielectric layer 31 is made of insulating material, and circuits are provided in both the first circuit layer 32 and the second circuit layer 33.

[0053] See Figure 2-4 After all the planar antenna plates 3 are fabricated, the planar antenna plates 3 are placed on the convex structure 11 of the lower structural member 1, and the concave structure 21 of the upper structural member 2 is placed on the convex structure 11. A preset pressure is applied above the upper structural member 2 or below the lower structural member 1, or a preset pressure is applied simultaneously above the upper structural member 2 and below the lower structural member 1, to form a curved antenna plate 4 with the same curvature as the convex structure 11 of the lower structural member 1. If it is the first case in step S100, the curved antenna plates 4 obtained by pressing have the same curvature, that is, there is only one type of curved antenna plate. If it is the second case in step S100, N types of curved antenna plates are obtained by pressing, and the curvature of each curved antenna plate is different.

[0054] In other embodiments, the upper structural member 2 can be placed in the lower part, the planar antenna plate 3 can be placed in the concave structure 21 of the upper structural member 2, the convex structure 11 of the lower structural member 1 can be placed on the concave structure 21, and a preset pressure can be applied below the upper structural member 2 or above the lower structural member 1, or a preset pressure can be applied simultaneously below the upper structural member 2 and above the lower structural member 1, thus forming a curved antenna plate 4.

[0055] In other embodiments, the upper structural member 2 and the lower structural member 1 can be placed in any way, and the planar antenna plate 4 can be placed between the concave structure 21 of the upper structural member 2 and the convex structure 11 of the lower structural member 1. Applying pressure on either side or applying pressure on both sides at the same time can form a curved antenna plate 4.

[0056] Step S300: According to the set sorting, the pressed curved antenna plates are spliced ​​together to obtain a curved antenna.

[0057] For the second scenario in step S100, the curved antennas obtained by pressing are sorted according to the curvature of the segmented surfaces to obtain the installation order of each curved antenna plate. Then, according to the installation order, the curved antenna plates are sequentially spliced ​​together using adhesive to obtain the following... Figure 3 The curved antenna S shown is shown.

[0058] For the first case in step S100, it is not necessary to sort the curved antenna plates. The curved antenna plates can be spliced ​​together in sequence using adhesive.

[0059] The method for manufacturing a curved antenna in this embodiment involves creating an upper and lower structural component of a structural fixture based on the curvature of the surface at the installation location of the curved antenna. The upper and lower structural components of the fixture are used to press together the planar antenna plates of the curved antenna into curved antenna plates with the same curvature as the surface at the installation location. Then, the curved antenna plates are assembled into a curved antenna by splicing them together according to the installation sequence. Curved antennas manufactured using this method can achieve seamless splicing between antenna plates and a tight fit with the curved surface at the installation location, improving the stability and safety of the curved antenna during use in electronic products.

[0060] In one embodiment, a method such as Figure 3 The curved antenna shown is mounted on the mounting surface 5 of the electronic product. The curved antenna includes a preset number of curved antenna plates 4, each of which has a preset curvature. The curved antenna plates 4 are sequentially spliced ​​together according to a set order.

[0061] In this embodiment, the curvature of the curved antenna plate 4 can be the same or different, depending on the curvature of the mounting surface 5 of the electronic product to be mounted on the curved antenna S.

[0062] like Figure 4 As shown, the curved antenna board 4 includes a second dielectric layer 41, a third circuit layer 42 and a fourth circuit layer 43. The third circuit layer 42 is located on one side of the second dielectric layer 41, and the fourth circuit layer 43 is located on the other side of the second dielectric layer 41. The circuits of the curved antenna are provided in both the third circuit layer 42 and the fourth circuit layer 43.

[0063] In this embodiment, a curved antenna is provided with a curved antenna plate having the same curvature as the surface at the installation location. The curved antenna plates are then assembled into a curved antenna by splicing. The curved antenna plates can form a seamless splice and fit tightly against the surface at the installation location, which improves the stability and safety of the curved antenna during the use of electronic products.

[0064] In one embodiment, a method such as Figure 5 The structural fixture shown includes an upper structural component 2 and a lower structural component 1. The upper structural component 2 has a concave structure 21 on one side and a planar structure on the other side. The lower structural component 1 has a convex structure 11 on one side and a planar structure on the other side. The curvature of the concave structure 21 and the convex structure 11 is the same as the curvature of each segment of the curved surface of the curved antenna at the installation position of the electronic product.

[0065] In one example, one side of the upper structural member 2 is a concave structure 21 and the other side is a non-planar structure, and one side of the lower structural member 1 is a convex structure 11 and the other side is a planar structure; or one side of the upper structural member 2 is a concave structure 21 and the other side is a planar structure, and one side of the lower structural member 1 is a convex structure 11 and the other side is a non-planar structure, both of which can achieve the function of the above-mentioned structural member tooling.

[0066] The structural fixture for pressing curved antennas in this embodiment can press each planar antenna plate into a curved antenna plate with the same curvature as each segment of the curved antenna at the installation position of the electronic product, so that the curved antenna plate fits tightly with the curved surface at the installation position, improving the stability and safety of the spliced ​​curved antenna during the use of the electronic product.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
