Description

Technical Field

[0001] This application relates to the field of communication equipment technology, and more specifically to a transparent ultra-wideband omnidirectional antenna. Background Technology

[0002] With the development of the communications industry and the improvement of people's living standards, as well as the increasing awareness of green environmental protection, the demand for aesthetically pleasing and concealed antennas is gradually increasing. Aesthetically pleasing and concealed antenna technologies can reduce people's fear of electromagnetic radiation and blend harmoniously with the surrounding environment. Existing ordinary indoor antennas are usually made of metal or PCB materials with an outer cover, resulting in considerable thickness, making concealed installation difficult and affecting aesthetics, especially in high-end venues and hotels. Existing ultra-thin antennas (such as patch antennas) reduce thickness but sacrifice performance (lower gain, narrower bandwidth). Existing traditional antennas require multiple independent antennas to cover 2G / 3G / 4G / 5G frequency bands (such as 700MHz~3.5GHz), leading to complex structures and increased size. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this application is to provide a transparent ultra-wideband omnidirectional antenna, thereby effectively solving the above-mentioned technical problems.

[0004] To achieve the above objectives, this application adopts the following technical solution: This application provides a transparent ultra-wideband omnidirectional antenna, including a support plate, an antenna film disposed on the surface of the support plate, a radiator disposed on the surface of the antenna film, the radiator being connected to the connector assembly, the radiator including a radiating sheet, the radiating sheet being a metal mesh structure, the metal mesh structure having a linewidth of 1µm to 100µm, a line spacing of 50µm to 3000µm, and a line thickness of 1µm to 20µm.

[0005] Furthermore, the radiating sheet includes a first radiating sheet and a second radiating sheet, and the first radiating sheet and the second radiating sheet are respectively provided with pads. The inner core of the power supply cable is welded to the pads of the first radiating sheet, and the outer conductor is welded to the pads of the second radiating sheet.

[0006] Furthermore, the feed branch extending from the first radiating plate is embedded inside the second radiating plate to form a coupling.

[0007] Furthermore, the first radiating sheet is provided with matching branches, and the second radiating sheet is provided with a hollowed-out portion.

[0008] Furthermore, the surface of the pad is provided with a matte inert metal plating.

[0009] Furthermore, an optical adhesive layer is provided between the antenna film and the support plate, and the antenna film and the support plate are bonded and fixed by the optical adhesive layer.

[0012] Furthermore, the antenna film comprises a low sheet resistance film.

[0013] Beneficial effects This design presents a transparent ultra-wideband omnidirectional antenna that utilizes a metal mesh radiating sheet. The dimensions of the mesh structure, including line width, spacing, and thickness, are precisely designed to maximize light transmittance. This ensures both antenna performance (300MHz-7200MHz) and improved transparency. The transparent antenna is a thin sheet with a small size and excellent light transmittance, allowing it to be placed inside buildings without compromising aesthetics while providing wireless communication functionality.

[0021] Example This application provides a transparent ultra-wideband omnidirectional antenna, such as Figure 1-3 As shown, the antenna includes a support plate 1, an antenna diaphragm 2 is disposed on the surface of the support plate 1, a radiator 3 is disposed on the surface of the antenna diaphragm 2, and the radiator 3 is connected to a connector 4 assembly, wherein: like Figure 2 As shown, the radiator 3 includes radiating plates, which include a first radiating plate 31 and a second radiating plate 32. The first radiating plate 31 and the second radiating plate 32 are respectively provided with pads 33. The surface of the pads 33 is provided with a matte inert metal plating layer, which is easy to solder and ensures the low intermodulation characteristics of the product. The inner core of the feed cable is soldered to the pads 33 of the first radiating plate 31, and the outer conductor is soldered to the pads 33 of the second radiating plate 32. The feed branch 34 extending from the first radiating plate 31 is embedded into the interior of the second radiating plate 32 to form coupling, which is beneficial for impedance matching in a wide frequency band. The first radiating plate 31 is provided with matching branches 35, and the second radiating plate 32 is provided with hollow parts 36, which can improve the current distribution between radiating units, thereby achieving miniaturization and broadband.

[0022] like Figure 1 As shown, an optical adhesive layer 5 is provided between the antenna film 2 and the support plate 1, and the antenna film 2 and the support plate 1 are bonded and fixed by the optical adhesive layer 5.

[0023] like Figure 1 As shown, the connector 4 assembly includes a connecting part 41, a plastic screw 42, and a plastic nut 43. The connecting part 41 is fixedly mounted on the plastic screw 42, and the plastic screw 42 and the plastic nut 43 are fixedly connected. The plastic parts protect the solder pads 33, fix the cable, and are used for antenna installation.

[0024] The support plate 1 includes a transparent support plate 1. The support plate 1 is made of materials such as polycarbonate, polymethyl methacrylate, transparent nylon, glass, graphene, polyethylene terephthalate, polyvinyl chloride, polystyrene, polypropylene, polyethylene, acrylonitrile-styrene copolymer, K resin, thermoplastic polyurethane, etc., and has a light transmittance of nearly 90%.

[0025] Antenna film 2 includes a low sheet resistance film, made of PET or ITO film material. Low sheet resistance can effectively reduce transmission loss and help improve antenna gain.

[0026] like Figure 3 As shown, the radiating sheet has a metal mesh structure with a line width of 1µm to 100µm, a line spacing of 50µm to 3000µm, and a line thickness of 1µm to 20µm.

[0027] In some embodiments, a metal mesh structure with a line width of 1µm, a line spacing of 50µm, and a line thickness of 1µm is used. The transmittance of the metal mesh structure radiating sheet of this size reaches 87.27%, and the power tolerance is 5W.

[0028] In some embodiments, a metal mesh structure with a line width of 5µm, a line spacing of 100µm, and a line thickness of 1µm is used. The transmittance of the metal mesh structure radiating sheet of this size reaches 88.23%, and the power tolerance is 20W.

[0029] In some embodiments, a metal mesh structure with a line width of 40µm, a line spacing of 500µm, and a line thickness of 4µm is used. The transmittance of the metal mesh structure radiating sheet of this size reaches 88.89%, and the power tolerance is 45W.

[0030] In some embodiments, a metal mesh structure with a line width of 60µm, a line spacing of 1000µm, and a line thickness of 10µm is used. The transmittance of the metal mesh structure radiating sheet of this size reaches 89.34%, and the power tolerance is 38W.

[0031] In some embodiments, a metal mesh structure with a line width of 100µm, a line spacing of 3000µm, and a line thickness of 20µm is used. The transmittance of the metal mesh structure radiating sheet of this size reaches 91.2%, and the power tolerance is 10W.

[0032] Based on the test results from the above embodiments, it can be seen that when the metal mesh linewidth is 5um to 60um, the line spacing is 100um to 1000um, and the line thickness is 1um to 10um, the transmittance and power tolerance are better. If the line spacing is too large, the transmittance will increase and the power tolerance will decrease.

[0033] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be used to limit the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit and essence of this application should be included within the scope of protection of this application.
