Abstract
Description
Technical Field
[0001] The utility model relates to the field of antenna structure design, in particular to an antenna. Background Art
[0002] With the rapid development of wireless communication technology, as one of the key components in the communication system, higher requirements are imposed on the performance and appearance of antennas. Although traditional antennas have good conductivity and radiation performance, they have great limitations in the wireless deployment requirements of explosion-proof products (fully metal body). To overcome this limitation, window transparent antennas have emerged.
[0003] Transparent antennas are usually made of transparent conductive materials such as indium tin oxide (ITO), zinc oxide (ZnO), etc. These materials have certain conductivity and can have high transparency while realizing the radiation function of the antenna. Transparent antennas generally have a conductive area and a filling area. Since the conductive area and the filling area are usually made of different materials, a difference in transparency is generated between the conductive area and the filling area, resulting in a large difference in the visual effects of the two. Summary of the Utility Model
[0004] Based on this, in view of the problem of poor visual effect of transparent antennas, it is necessary to provide an antenna.
[0005] An antenna includes a substrate, and a first isolation ring is etched on the upper surface of the substrate to form an antenna area and a filling area on the substrate. The antenna area is located within the first isolation ring, and the filling area is located outside the first isolation ring.
[0006] The first isolation ring of the utility model includes at least one straight etching section.
[0007] A second isolation ring is further etched on the upper surface of the substrate of the utility model to form a ground wire area on the substrate. The ground wire area is located within the second isolation ring. The first isolation ring and the second isolation ring are arranged at intervals, and the filling area is located outside the second isolation ring.
[0008] The distance between the ground wire area and the antenna area of the utility model is not less than 2 mm.
[0009] Conductive meshes are attached to the antenna area, the ground wire area and the filling area of the utility model, and the conductive meshes avoid the first isolation ring and the second isolation ring.
[0010] The material of the conductive mesh of the utility model is indium tin oxide, fluorine-doped tin oxide or silver-plated polymer.
[0011] The second isolation ring of the utility model includes at least one straight etching section.
[0012] The area of the antenna region described in this utility model is larger than the area of the ground wire region.
[0013] The antenna described in this utility model further includes a first antireflection insulating coating, and the first antireflection insulating coating covers the upper surface of the substrate.
[0014] The antenna described in this utility model further includes a second antireflection insulating coating, and the second antireflection insulating coating is disposed on the lower surface of the substrate.
[0015] The beneficial effects of this utility model are as follows:
[0016] A first isolation ring is formed on the upper surface of the substrate by etching, and thus the antenna region and the filling region are formed. On the one hand, it ensures that the antenna region and the filling region have the same material, and their transmittance rates are similar, ensuring the overall visual effect of the antenna. On the other hand, the antenna region and the filling region obtain an insulating effect through the first isolation ring, ensuring that the antenna can work normally. Description of the Drawings

[0029] Embodiment 1:
[0030] Refer to Figure 1 , this embodiment provides an antenna, including a substrate 1. A first isolation ring 11 and a second isolation ring 14 are etched on the upper surface of the substrate 1. Both the first isolation ring 11 and the second isolation ring 14 can play a role in insulation and disconnecting electrical connections.
[0031] Both the first isolation ring 11 and the second isolation ring 14 are closed figures, and the first isolation ring 11 and the second isolation ring 14 are arranged at intervals, that is, the first isolation ring 11 and the second isolation ring 14 are not in contact. Thus, an antenna area 12, a ground line area 15 and a filling area 13 are formed on the upper surface of the substrate 1. Among them, the antenna area 12 is located within the first isolation ring 11, and the antenna area 12 is formed by enclosing the first isolation ring 11. The ground line area 15 is located within the second isolation ring 14, and the ground line area 15 is formed by enclosing the second isolation ring 14. Therefore, the antenna area 12 and the ground line area 15 are also arranged at intervals. The filling area 13 is simultaneously located outside both the first isolation ring 11 and the second isolation ring 14. That is, in this embodiment, the filling area 13 is the part of the upper surface of the substrate 1 except the first isolation ring 11, the second isolation ring 14, the antenna area 12 and the ground line area 15.
[0032] Before the first isolation ring 11 and the second isolation ring 14 are etched on the substrate 1 in this embodiment, the upper surface thereof is a conductive thin film. Therefore, the etching process is essentially a destruction of the conductive thin film. The first isolation ring 11 and the second isolation ring 14 are structures generated after the conductive thin film is etched and damaged. Therefore, the first isolation ring 11 and the second isolation ring 14 can play an insulating effect. On the contrary, the antenna area 12, the ground line area 15 and the filling area 13 are parts of the conductive thin film that have not been etched and damaged. Therefore, the antenna area 12, the ground line area 15 and the filling area 13 can still play a conductive role. At the same time, for the antenna in this embodiment, the electrical connections between the antenna area 12, the ground line area 15 and the filling area 13 are in a disconnected state. This ensures the normal operation of the antenna in this embodiment.
[0033] Specifically, the electrical connection between the antenna region 12 and the filling region 13 is disconnected by the insulating effect of the first isolation ring 11. The electrical connection between the ground line region 15 and the filling region 13 is disconnected by the insulating effect of the second isolation ring 14. The electrical connection between the antenna region 12 and the ground line region 15 is disconnected by the insulating effects of the first isolation ring 11 and the second isolation ring 14.
[0034] It is easy to understand that the antenna region 12, the ground line region 15, and the filling region 13 are from the same conductive thin film. Therefore, the antenna region 12, the ground line region 15, and the filling region 13 have the same material and similar thicknesses, and thus have similar transmittance. This ensures that the visual differences between different positions of the final antenna are small.
[0035] In this embodiment, the conductive thin film is in a grid shape. Therefore, after etching is completed, conductive grids are attached to the antenna region 12, the ground line region 15, and the filling region 13. The conductive grids can improve the light transmittance at the antenna region 12, the ground line region 15, and the filling region 13.
[0036] Generally speaking, the material of the conductive grids is indium tin oxide, fluorine-doped tin oxide, or silver-plated polymer.
[0037] To meet the requirements of the design specifications, the distance between the ground line region 15 and the antenna region 12 is not less than 2 mm. Here, the distance between the ground line region 15 and the antenna region 12 specifically refers to the minimum distance between the boundary of the ground line region 15 and the boundary of the antenna region 12.
[0038] It is easy to understand that the specific shapes of the antenna region 12 and the ground line region 15 in this embodiment are respectively determined by the shapes of the first isolation ring 11 and the second isolation ring 14. There are no specific design requirements for the shapes of the antenna region 12 and the ground line region 15, as long as they can meet the normal working requirements of the antenna. Therefore, the shapes of the first isolation ring 11 and the second isolation ring 14 are not limited to circles. For example, in this embodiment, the first isolation ring 11 is formed by enclosing a plurality of straight etching segments connected end to end in sequence, and the second isolation ring 14 is also formed by enclosing a plurality of straight etching segments connected end to end in sequence. In some other embodiments, the shape of the first isolation ring 11 can be a closed curve, or can be formed by enclosing a plurality of straight etching segments and a plurality of curved etching segments connected end to end in sequence. The shape of the second isolation ring 14 can also be a closed curve, and can also be formed by enclosing a plurality of straight etching segments and a plurality of curved etching segments connected end to end in sequence. That is, there is no obvious direct mutual restriction relationship between the shape of the first isolation ring 11 and the shape of the second isolation ring 14. However, in most cases, the area of the antenna region 12 is larger than the area of the ground line region 15.
[0039] See Figure 2 , in some other embodiments, by changing the shapes of the first isolation ring 11 and the second isolation ring 14, the antenna can be applied to the 5G field. At this time, both the first isolation ring 11 and the second isolation ring 14 are formed by enclosing a plurality of straight etching segments and a plurality of curved etching segments in sequence end to end.
[0040] It is easy to understand that the first isolation ring 11 includes a plurality of straight etching segments, which can appropriately reduce the preparation difficulty of the first isolation ring 11 and improve the preparation accuracy of the first isolation ring 11. The second isolation ring 14 includes a plurality of straight etching segments, which can also appropriately reduce the preparation difficulty of the second isolation ring 14 and improve the preparation accuracy of the second isolation ring 14.
[0041] Preferably, see Figure 3 , the antenna in this embodiment further includes a first antireflection insulating coating 2 and a second antireflection insulating coating 3. The first antireflection insulating coating 2 can cover the upper surface of the substrate 1 to protect the antenna area 12, the ground wire area 15, and the filling area 13. The second antireflection insulating coating 3 is disposed on the lower surface of the substrate 1. Both the first antireflection insulating coating 2 and the second antireflection insulating coating 3 can play a role in improving the transmittance of the antenna.
[0042] See Figure 4 , the light transmittance of the antenna in this embodiment is on average above 90%.
[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0044] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
