In this way, while increasing the application scenarios of the film antenna, the through hole cooperates with the components on the product on which the film antenna is installed, and it can also meet the needs of high integration and multi-function. Example

[0031] The utility model provides a flexible film antenna. Figures 1 to 3 As shown, it includes: an antenna body 1, the antenna body 1 includes a first thin film base layer 11, a second thin film base layer 12 and an antenna element 13, the antenna element 13 is arranged between the first thin film base layer 11 and the second thin film base layer 12, one side of the antenna body 1 is provided with an end 2 protruding from the antenna body 1, and one end of the antenna element 13 is arranged at the end 2; a through hole 3, the through hole 3 is arranged on the antenna body 1, and the antenna element 13 is arranged around the through hole 3.

[0032] Thus, by providing a protruding end 2 on one side of the antenna body 1 and placing one end of the antenna element 13 thereon, and providing a through hole 3 on the antenna body 1 and arranging the antenna element 13 around the through hole 3, the requirements of lightness, thinness, high integration and multi-function are achieved. This flexible film antenna has a wide range of application prospects and will play an important role in future electronic products.

[0033] The antenna body 1 is composed of a first film base layer 11 and a second film base layer 12, between which an antenna element 13 is arranged. This structure makes the antenna have excellent flexibility and bendability, and can adapt to various complex installation environments and shape requirements.

[0034] The flexible film antenna is made of film material, which is light and thin, and is suitable for use in lightweight electronic products. By setting a through hole 3 on the antenna body 1 and cooperating with other components, a highly integrated structure is achieved, making the electronic product more compact and efficient.

[0035] On one side of the antenna body 1, an end portion 2 is provided which protrudes from the antenna body 1. One end of the antenna element 13 is provided on this end portion 2 to ensure that it can be stably positioned when connected or fixed. This makes it convenient to install and use the antenna even after being lightened, miniaturized and thinned. Figure 2 As shown, because the end portion 2 is protruding from the antenna body 1, when using the flexible film antenna provided by the embodiment of the utility model, the existence of the end portion 2 can be quickly discovered, and then it can be quickly installed, reducing the difficulty and time cost of installation.

[0036] One or more through holes 3 are provided on the antenna body 1. These through holes 3 are located around the antenna element 13, and the antenna element 13 is arranged around the through holes 3. This structure increases the application scenarios of the thin film antenna and allows interaction with components of other devices or other structures.

[0037] Through the through hole 3, other components on the product equipped with the film antenna can be matched with each other, such as connectors, fixings, etc. This not only improves the integration of the product, but also increases the diversity of functions. Figure 2As shown, because the through hole 3 is the hollowed-out part in the thin film antenna, after the thin film antenna is installed on the product, the through hole 3 can accommodate the components of the product, so that the product can be connected to the antenna element 13 in the thin film antenna through the through hole 3. The provision of the through hole 3 can increase the application scenarios of the thin film antenna, so that it can meet the requirements of more different functions and needs. The antenna element 13 is arranged around the through hole 3, which ensures good signal reception and transmission performance, ensures that the electronic product can work stably in various environments, and can also facilitate the connection between the device and the antenna element 13.

[0038] like Figure 2 As shown, more specifically, the antenna body 1 is provided with two through holes 3, and an antenna element 13 is provided between the two through holes 3. Such a thin film antenna can be better applied to a car dashboard or a head-mounted interactive display device. The antenna element 13 is disposed between the two through holes 3 and arranged around them. This structure can ensure that the effective working area of ​​the antenna element 13 is maximized while avoiding interference with other components. The material and shape of the antenna element 13 are optimized according to the specific application scenario to ensure that the wireless signal can be stably and efficiently received and transmitted on the car dashboard or head-mounted interactive display device.

[0039] Among them, the flexible film antenna provided by the embodiment of the utility model is installed on the car dashboard, which can conveniently receive and transmit the wireless signals required by the vehicle, such as GPS positioning, car phone, etc. The antenna element 13 is arranged around the through hole 3 to ensure that a good signal reception effect can be obtained at any position on the dashboard. At the same time, through the through hole 3, it can cooperate with other components on the dashboard to achieve higher integration and functional diversity.

[0040] Installing the flexible film antenna provided by the embodiment of the utility model on the head-mounted interactive display device can provide users with a stable wireless connection experience, such as virtual reality, augmented reality and other applications. The flexible design of the antenna element 13 can ensure that good signal reception can be obtained at any position on the head-mounted device. Through the through hole 3, it can cooperate with other components on the head-mounted device to achieve tighter integration and more functional expansion.

[0041] More specifically, the distance between the two through holes 3 is greater than or equal to 8 mm. In this way, more antenna elements 13 can be arranged between the through holes 3, such as various wiring schemes such as double-line and multi-line, which can not only enhance signal transmission and increase operability, but also increase the strength of the film antenna itself, and reduce the damage or even breakage caused by the small distance between the through holes 3 during use.

[0042] like Figure 2 and Figure 3As shown, more specifically, one end of the antenna element 13 enters the antenna body 1 from the end 2, surrounds the through hole 3, and then returns to the end 2. One end of the antenna element 13 enters from the protruding end 2 on one side of the antenna body 1, and then surrounds the two through holes 3 between the two thin film base layers for wiring. After the wiring is completed, the other end of the antenna element 13 returns to the starting protruding end 2 again to form a closed wiring loop. This wiring method surrounding the through hole 3 not only optimizes the signal transmission path, but also enhances the strength and stability of the antenna element 13.

[0043] like Figure 3 As shown, the end portion 2 may be provided with a test area 21. More specifically, the test area 21 may include a first resistance test point 211 and a second resistance test point 212. By providing resistance test points on the antenna body 1, the resistance of the antenna element 13 may be accurately measured and compared, thereby evaluating its performance and quality.

[0044] like Figure 3 As shown, more specifically, the first resistance test point 211 is disposed at one end of the antenna body 1 , and the second resistance test point 212 is disposed at the other end of the antenna body 1 .

[0045] In this way, the two resistance test points are located at both ends of the antenna body 1, which is convenient for contact testing using a resistance test instrument, so as to accurately evaluate the resistance performance and overall quality of the antenna. The resistance test points are located at both ends of the antenna body 1, which is convenient for contact testing using a resistance test instrument, without disassembling or moving the antenna body 1. Through accurate resistance testing, possible quality problems or performance degradation of the antenna can be discovered in time, thereby ensuring the reliability and stability of the antenna, and also providing strong support for its wide application in various application scenarios.

[0046] More specifically, the aperture of the through hole 3 is greater than or equal to 100 mm. A through hole 3 with a larger aperture can be adapted to a wider variety of products, thereby improving the applicable scenarios of a flexible film antenna provided by an embodiment of the utility model. A through hole 3 with a larger aperture can be adapted to a wider variety of products, such as larger connectors, cables, etc., thereby improving the versatility and flexibility of the antenna. At the same time, a large-aperture through hole 3 also provides a larger space for the wiring of the antenna element 13, thereby helping to implement a more complex wiring scheme.

[0047] The first film base layer 11 and the second film base layer 12 are both made of PET material, and the antenna element 13 is made of silver paste. More specifically, the thickness of the first film base layer 11 and the second film base layer 12 can be less than or equal to 0.2 mm, so that the first film base layer 11 and the second film base layer 12 can be made of PET (polyethylene terephthalate). PET is a plastic material with excellent physical properties, chemical stability and electrical properties, and is suitable for making film antennas. The antenna element 13 is made of silver paste. Silver paste has the advantages of good conductivity, good flexibility, stable performance, and not easy to oxidize, and is suitable for making printed antennas. The thickness of the first film base layer 11 and the second film base layer 12 is less than or equal to 0.2 mm. This lightweight structure makes the antenna lighter, easy to integrate in various devices, and helps to achieve the overall lightweight of the device.

[0048] like Figure 1 As shown, more specifically, a mounting portion 4 is further provided on the surface of the antenna body 1. The mounting portion 4 may be provided on one side of the antenna body 1, and various mounting methods such as welding and pasting may be used. When the pasting method is selected, a flexible film antenna provided by an embodiment of the utility model may be pasted to the product by materials such as double-sided tape and glue. In this way, the mounting portion 4 is provided on one side of the antenna body 1, which is convenient for users or manufacturers to install and fix the antenna. The mounting portion 4 supports a variety of installation methods, including but not limited to welding and pasting. When the welding method is selected, the antenna can be welded to the product according to the product design and production requirements to ensure the stability and reliability of the connection. When the pasting method is selected, the antenna can be pasted to the product using materials such as double-sided tape and glue. This installation structure is simple and quick, and is suitable for various smooth surfaces. Compared with the prior art, the flexible film antenna provided in the embodiment of the utility model has an end portion protruding from the antenna body on one side of the antenna body, and one end of the antenna element is arranged on the end portion, so that it can be convenient for installation and use after being lightweight and thin; a through hole is arranged on the antenna body, and the antenna element is arranged around the through hole.
