Description

Technical Field

[0001] The present invention relates to the field of thin film technology, in particular to a millimeter wave antenna film. Background Art

[0002] The millimeter wave band used by 5G is easily affected by various building structures, resulting in communication barriers. Therefore, expanding the 5G communication range requires the support of infrastructure, and transparent antenna films can be flexibly installed on glass windows, car body glass, etc., to quickly expand the communication network. Traditional antenna films form copper wiring in a grid shape on the surface of the film for signal relay. Since the film itself has a certain toughness, it will deform to a certain extent when subjected to tensile force. The deformation degree of the copper wiring is smaller than the deformation degree of the film, so the copper wiring is often stretched and broken. Summary of the Invention

[0003] The object of the present invention is to provide a millimeter wave antenna film to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a millimeter wave antenna film, comprising a base film, a cover film, an antenna embedded groove, a contact embedded groove, a tile antenna portion and a docking rib, the surfaces of the base film and the cover film are respectively provided with an antenna embedded groove, and both sides of the antenna embedded groove are respectively provided with a contact embedded groove, the tile antenna portion is attached and fixed inside the antenna embedded groove, and both sides of the tile antenna portion are respectively fixed with docking ribs, the docking ribs are embedded and fixed inside the contact embedded groove, and a positioning structure is provided between the docking ribs of the base film and the docking ribs of the cover film.

[0005] The antenna embedded grooves are arranged in a grid shape, and the bottom cross section thereof is arc-shaped.

[0006] The tile antenna portion is in the shape of a rectangular thin sheet and is bent into an arc shape according to the arc-shaped bottom of the antenna embedded groove.

[0007] The positioning structure includes a positioning base groove and a positioning insertion block.

[0008] The positioning base groove is provided on the surface of the butt joint rib corresponding to the base film, and the positioning insert block is fixedly arranged on the surface of the butt joint rib corresponding to the cover film.

[0009] The cross section of the positioning base groove is rectangular, and the positioning insertion block is in the shape of a rectangular strip. When the base film and the covering film are docked and matched, the positioning insertion block is inserted into the interior of the positioning base groove.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The millimeter-wave antenna film of the present invention has an arc-shaped curved tile antenna portion, so that when the film is subjected to tensile deformation, the arc diameter of the tile antenna portion increases and extends to both sides, thereby reducing the possibility of the tile antenna portion breaking when the film is deformed, making the manufactured millimeter-wave antenna film more stable and able to be stretched to a certain extent without causing damage to the internal antenna band.

[0012] When the base film and the cover film are butted and pasted together, the tile antenna parts can be butted together to form a flat tubular structure, thereby increasing the projection area of ​​the antenna at various angles and making the antenna signal more stable.

[0013] The positioning structure provided can increase the stability of the butt joint ribs during contact, avoid butt displacement when the tile antenna portion is stretched, and at the same time increase the conduction effect between the two butt joint ribs, making the conduction between the two butt joint ribs more stable.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5The present invention provides a technical solution: a millimeter wave antenna film, comprising a base film 1, a cover film 2, an antenna embedded groove 3, a contact embedded groove 4, a tile antenna portion 5 and a docking rib 6. The surfaces of the base film 1 and the cover film 2 are respectively provided with an antenna embedded groove 3, and contact embedded grooves 4 are respectively provided on both sides of the antenna embedded groove 3. The tile antenna portion 5 is attached and fixed inside the antenna embedded groove 3, and docking ribs 6 are fixed on both sides of the tile antenna portion 5. The docking ribs 6 are embedded and fixed inside the contact embedded groove 4. A positioning structure is provided between the docking ribs 6 of the base film 1 and the docking ribs 6 of the cover film 2. The base film 1 and the cover film 2 are made of the same material and can both be made of cycloolefin polymer, which has high transparency and excellent dielectric properties.

[0022] The antenna embedded slots 3 are arranged in a grid shape, and the cross section of the bottom thereof is arc-shaped.

[0023] The tile antenna part 5 is in the shape of a rectangular thin sheet. The tile antenna part 5 is bent into an arc shape according to the arc-shaped bottom of the antenna embedded groove 3. The tile antenna part 5 and the connecting rib 6 are both made of copper.

[0024] The positioning structure includes a positioning base groove 601 and a positioning insert block 602 . The positioning base groove 601 is opened on the surface of the docking rib 6 corresponding to the base film 1 , and the positioning insert block 602 is fixedly set on the surface of the docking rib 6 corresponding to the covering film 2 .

[0025] The cross section of the positioning base groove 601 is rectangular, and the positioning insert block 602 is rectangular and strip-shaped. When the base film 1 and the cover film 2 are docked, the positioning insert block 602 is inserted into the positioning base groove 601 .

[0026] When the present invention is used, Figure 1 As shown in FIG, the base film 1 and the cover film 2 are in a pasted and fixed state, and the positioning insert block 602 is inserted into the interior of the positioning base groove 601 .

[0027] When the film is stretched and deformed by tensile force during installation or transportation, the curvature of the tile antenna portion 5 is reduced due to the tensile force, so that the tile antenna portion 5 extends to both sides and deforms along with the stretching of the film, thereby preventing the copper wiring inside the film from breaking.

[0028] Since the positioning insertion block 602 is inserted into the positioning base groove 601, the docking ribs 6 corresponding to the base film 1 and the docking ribs 6 corresponding to the covering film 2 can maintain relative positions, avoiding misalignment between the docking ribs 6 when the film is stretched and deformed, and at the same time increasing the signal conduction stability between the docking ribs 6.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
