Description

Technical Field

[0001] This invention relates to the field of transparent antenna technology, specifically to a transparent antenna fabricated using COP copper film. Background Technology

[0002] 5G / 6G communication uses high-frequency bands, making it highly susceptible to interference from nearby materials and equipment. Therefore, a large number of transparent 5G / 6G antennas are needed, ideally placed on various transparent glass surfaces. Transparent antennas using transparent conductive film technology do not obstruct the functionality and design of displays, windows, etc., and can be deployed in any location.

[0003] Existing transparent antennas fabricated using COP copper films involve forming copper wirings, a few micrometers wide, in a mesh shape almost invisible to the naked eye on a thin film with good transparency and dielectric properties. However, the copper wirings themselves lack stretchability, and their small diameter makes it easy for the internal copper wirings to break when the thin-film antenna is subjected to slight deformation, thus affecting the overall signal transmission and reception quality of the antenna. Summary of the Invention

[0004] The purpose of this invention is to provide a transparent antenna fabricated using COP copper film to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transparent antenna made using COP copper film, comprising a carrier film, a radiating film, and a conductive film. The conductive film is attached to the surface of the carrier film, and a positioning frame is provided on the outer periphery of the conductive film. The carrier film is fixedly connected to one side of the positioning frame, and the radiating film is fixedly connected to the other end of the positioning frame. The radiating film is attached to the surface of the conductive film. The conductive film is a grid structure composed of multiple No. 1 copper wires and multiple No. 2 copper wires. A copper wire positioning unit is provided at the intersection point of two adjacent No. 1 copper wires and No. 2 copper wires.

[0006] Preferably, the copper wire positioning unit includes a base plate, a middle support plate, and a shielding plate. The base plate is fixedly connected to the middle support plate by a vertical block, and the middle support plate is fixedly connected to the shielding plate by a horizontal block.

[0007] Preferably, a set of spring pieces is fixedly provided on both the vertical block and the horizontal block, and a copper wire support is fixedly connected to the end of the spring piece away from the block, with the copper wire wound on the copper wire support.

[0008] Preferably, the spring is an S-shaped spring, and the copper wire support has an arc-shaped structure.

[0009] Preferably, the end of the copper wire support away from the shielding disc is fixedly connected to two sets of guide blocks, and the bottom support disc and the middle support disc are each provided with two grooves to accommodate the guide blocks.

[0010] Preferably, the base disc is fixedly connected to the side wall of the carrier film, and the shielding disc is fixedly connected to the radiation film.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. This invention sets up multiple copper wire positioning units to form a stable grid shape with multiple No. 1 copper wires and multiple No. 2 copper wires. Furthermore, each copper wire is bent into an arc shape at the contact point with each copper wire positioning unit, which makes the copper wires deformable, reduces the probability of breakage, and ensures the overall performance quality of the transparent antenna.

[0013] 2. This invention, by using a base support disc, a middle support disc, and a shielding disc in combination, can simultaneously snap together copper wire No. 1 and copper wire No. 2, and the installation positions of adjacent copper wires are independent and do not interfere with each other, which is beneficial to the assembly and organization of copper wires; and by using a spring clip in conjunction with the copper wire holder, each copper wire forms an arc-shaped structure at the contact point with each copper wire positioning unit, thereby allowing for the stretching length of the copper wire to deform.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 5 This invention provides a technical solution: a transparent antenna fabricated using COP copper film, comprising a carrier film 1, a radiating film 2, and a conductive film 4. The conductive film 4 is attached to the surface of the carrier film 1. The carrier film 1 uses COP as a transparent substrate. COP is colorless and transparent, used in optical devices such as lenses and liquid crystal phasor films, and has high transparency. Furthermore, COP, as a transparent solid, possesses superior dielectric properties, making it suitable for high-frequency products. A positioning frame 3 is provided on the outer periphery of the conductive film 4. Thermoplastic resin is adhered to both the front and back sides of the positioning frame 3, and is thermally welded to the carrier film 1 and the radiating film 2 by auxiliary heating. The carrier film 1 is fixedly connected to one side of the positioning frame 3, and the radiating film 2 is fixedly connected to the other end of the positioning frame 3. The radiating film 2 is attached to the surface of the conductive film 4. The conductive film 4 is a mesh structure composed of multiple No. 1 copper wires 5 and multiple No. 2 copper wires 6. A copper wire positioning unit is provided at the intersection point of two adjacent No. 1 copper wires 5 and No. 2 copper wires 6.

[0022] This invention sets up multiple copper wire positioning units to form a stable grid shape with multiple No. 1 copper wires 5 and multiple No. 2 copper wires 6. Furthermore, each copper wire is bent into an arc shape at the contact point with each copper wire positioning unit, which makes the copper wires deformable, reduces the probability of breakage, and ensures the overall performance quality of the transparent antenna.

[0023] The copper wire positioning unit includes a base disc 7, a middle support disc 9, and a shielding disc 7. The base disc 7 is fixedly connected to the middle support disc 9 via a vertical block 8, and the middle support disc 9 is fixedly connected to the shielding disc 11 via a horizontal block 10. The base disc 7 is fixedly connected to the side wall of the carrier film 1, and the shielding disc 11 is fixedly connected to the radiation film 2. A set of spring tabs 14 are fixedly installed on both the vertical block 8 and the horizontal block 10. A copper wire support 12 is fixedly connected to the end of the spring tab 14 away from the block, and the copper wire is wound around the copper wire support 12. The spring tab 14 is an S-shaped spring tab, and the copper wire support 12 has an arc-shaped structure.

[0024] This invention, through the coordinated use of a base support disc 7, a middle support disc 9, and a shielding disc 7, can simultaneously engage copper wire 5 and copper wire 6 of the first type. Furthermore, the installation positions of adjacent copper wires are independent and do not interfere with each other, which is beneficial for the assembly and organization of copper wires. By using a spring disc 14 in conjunction with a copper wire support 12, an arc-shaped structure is formed at the contact point between each copper wire and each copper wire positioning unit, thereby allowing for the stretching length of the copper wire to deform.

[0025] Two sets of guide blocks 13 are fixedly connected to the end of the copper wire support 12 away from the shielding disc 11. Two grooves 15 for accommodating the guide blocks 13 are provided on both the bottom support disc 7 and the middle support disc 9. Both the guide blocks 13 and the grooves 15 are trapezoidal structures. By setting the guide blocks 13 and the grooves 15 to work together, they can guide and limit the movement of the copper wire support 12.

[0026] In use, multiple No. 1 copper wires 5 are first wound sequentially between the bottom support disc 7 and the middle support disc 9, and then multiple No. 1 copper wires 5 are wound sequentially between the middle support disc 9 and the shielding disc 11, thereby forming a grid-like thin film structure. The installation positions of adjacent groups of copper wires are independent and do not interfere with each other, which is beneficial to the assembly and sorting of copper wires.

[0027] When the thin-film antenna undergoes overall deformation, both copper wire 5 and copper wire 6 are subjected to force on the copper wire support 12, causing the copper wire support 12 to compress the spring piece 14. This allows copper wire 5 and copper wire 6 to perform corresponding stretching actions according to the degree of deformation, preventing breakage and ensuring the overall performance quality of the transparent antenna.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
