[0002] With the rapid development of augmented reality glasses, virtual reality glasses, vision correction glasses, and protective glasses, intelligence and lightweighting have become major trends in eyewear, gradually penetrating into various fields. Antennas, as important components for wireless signal reception and transmission, play a key role in meeting these intelligent and lightweight design requirements.

[0003] However, traditional antennas are located on the temples of glasses, which are close to the human head and have limited design space, resulting in reduced electromagnetic performance of the antenna. Summary of the Invention

[0004] The purpose of this application is to provide a transparent antenna lens and smart glasses, aiming to solve the problem of low electromagnetic performance of traditional antennas.

[0005] The present application provides a transparent antenna lens, comprising: Lens body; A transparent antenna, comprising an antenna transparent substrate and a plurality of first metal structures; The antenna transparent substrate is arranged on the lens body; A plurality of the first metal structures are disposed on the surface of the antenna transparent substrate, and the plurality of the first metal structures are disposed away from the lens body; A plurality of the first metal structures are connected to surround and form an irregularly arranged polygonal metal grid for transmitting and receiving wireless signals.

[0006] In some embodiments, the transparent antenna further comprises: a plurality of second metal structures, disposed on the same surface of the antenna transparent substrate as the plurality of first metal structures; At least some of the second metal structures among the plurality of second metal structures are connected to surround and form an irregularly arranged broken metal grid, and the polygonal metal grid is disposed in an area surrounded by the broken metal grid.

[0007] In some embodiments, the density of the broken metal grid decreases along the extension direction of the polygonal metal grid toward the edge of the lens.

[0008] In some embodiments, an isolation region is provided between the fractured metal grid and the polygonal metal grid.

[0009] In some embodiments, the transparent antenna further comprises: a transparent covering layer, disposed on a surface of the antenna transparent substrate, and the transparent covering layer covers the first metal structures and the second metal structures; The transparent connecting layer is disposed on the surface of the transparent covering layer, and the transparent connecting layer is disposed away from the lens body.

[0010] In some embodiments, the transparent antenna further comprises: The first antireflection film layer is arranged on both sides of the antenna transparent substrate opposite to the transparent cover layer.

[0011] In some embodiments, the transparent antenna lens further comprises: The first transparent protection component is arranged on the surface of the transparent connection layer, and the first transparent protection component is arranged away from the lens body.

[0012] In some embodiments, the transparent antenna lens further comprises: a second transparent protective component, disposed on both sides of the lens body opposite to the transparent antenna; The second transparent protection component is connected to the lens body via a first annular connection structure, and the second transparent protection component, the lens body and the first annular connection structure surround and form a first air layer.

[0013] In some embodiments, the transparent antenna is connected to the lens body via a second annular connection structure, and the transparent antenna, the lens body, and the second annular connection structure surround and form a second air layer.

[0014] The present application provides a pair of smart glasses comprising the transparent antenna lenses described in any one of the above embodiments.

[0015] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: Multiple first metal structures are disposed on the surface of the antenna transparent substrate, and these structures are positioned away from the lens body. This can be understood as the multiple first metal structures being disposed on opposite sides of the antenna transparent substrate relative to the lens body. The antenna transparent substrate, serving as a base for attaching the multiple first metal structures, provides support for the multiple first metal structures, making the transparent antenna more stable and reliable. Furthermore, the antenna transparent substrate is disposed on the lens body, integrating the transparent antenna with the lens body. The antenna transparent substrate and the lens body provide mutual support, ensuring the structural stability of the transparent antenna lens.

[0016] Multiple first metal structures are connected to each other, and the irregularly arranged polygonal metal grid formed by surrounding them forms the core structure of the transparent antenna. The irregularly arranged polygonal metal grid formed by the multiple first metal structures can be understood as a mesh structure formed by the irregular arrangement of multiple polygonal metal lattices. The irregularly arranged polygonal metal grid can efficiently conduct and radiate electromagnetic waves, thereby realizing the transmission of wireless signals and converting electrical signals into electromagnetic waves for transmission. At the same time, the irregularly arranged polygonal metal grid formed by the multiple first metal structures can realize the reception of wireless signals and convert electromagnetic waves into electrical signals. Furthermore, the irregularly arranged polygonal metal grid formed by the multiple first metal structures can transmit and receive wireless signals and realize the function of a transparent antenna.

[0017] Furthermore, the irregularly arranged polygonal metal grid formed by the interconnected and enclosing multiple first metal structures is disordered and irregular in position. Consequently, when light waves pass through the irregularly arranged polygonal metal grid, the phase differences of the secondary wave sources generated at each polygonal metal grid are random, with no consistent superposition direction. When light waves pass through the irregularly arranged polygonal metal grid, interference in all directions cancels each other out, averaging the interference effect and destroying the coherent interference generated by the periodic metal grid being equivalent to a grating. Since interference is often accompanied by diffraction, the two together constitute the core phenomena of wave optics. Therefore, the irregularly arranged polygonal metal grid formed by the interconnected and enclosing multiple first metal structures can achieve a more uniform light intensity distribution through the transparent antenna lens, reducing diffraction fringes and presenting a diffuse (also understood as scattering) effect. This solves the problem of bright diffraction fringes and dark areas caused by the superposition of wave peaks caused by the periodic metal grid.

[0018] Therefore, the transparent antenna lens provided by this application combines the lens body and the transparent antenna, which can support each other, allowing the transparent antenna to be set on the lens of the glasses. As a result, the design space of the transparent antenna is no longer limited by the size of the temples and is far away from the human head. This solves the problems of low electromagnetic performance caused by the human body's absorption and scattering of electromagnetic waves and size limitations, and greatly improves the electromagnetic performance of the transparent antenna to achieve better signal coverage and transmission. In addition, the transparent antenna lens provided by this application can solve the problem of bright diffraction stripes and dark areas caused by coherent interference generated by periodic metal grids, allowing users to see clearer and more accurate images.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In addition, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit differences.

[0025] In this application, unless otherwise specified, " / " indicates an "or" relationship between the associated objects. For example, A / B can mean either A or B. "And / or" in this application simply describes an association between associated objects, indicating that three relationships can exist.

[0026] See Figure 1The present application provides smart glasses 300. Smart glasses 300 may be AR glasses or VR glasses. Smart glasses 300 include a transparent antenna lens 100 and a frame 200. The transparent antenna lens 100 is disposed on the frame 200. The frame 200 supports the transparent antenna lens 100, allowing the smart glasses 300 to fit the user's face and ensure wearing comfort.

[0027] See Figure 2 and Figure 3 The present application provides a transparent antenna lens 100. The transparent antenna lens 100 includes a lens body 10 and a transparent antenna 20. The transparent antenna 20 includes an antenna transparent substrate 210 and a plurality of first metal structures 220. The antenna transparent substrate 210 is disposed on the lens body 10. The plurality of first metal structures 220 are disposed on the surface of the antenna transparent substrate 210, and the plurality of first metal structures 220 are disposed away from the lens body 10. The plurality of first metal structures 220 are connected and surround to form an irregularly arranged polygonal metal grid for transmitting and receiving wireless signals.

[0028] In this embodiment, the lens body 10 is the core optical structure of the transparent antenna lens 100, which can realize the core functions of the glasses through optical design and physical properties, such as augmented reality, virtual reality, vision correction or protection.

[0029] Multiple first metal structures 220 are disposed on the surface of the antenna transparent substrate 210, and are positioned away from the lens body 10. This means that the multiple first metal structures 220 are disposed on opposite sides of the antenna transparent substrate 210 relative to the lens body 10. The antenna transparent substrate 210 serves as an attachment base for the multiple first metal structures 220, providing support for the multiple first metal structures 220 and making the transparent antenna 20 more stable and reliable. Furthermore, the antenna transparent substrate 210 is disposed on the lens body 10, effectively integrating the transparent antenna 20 with the lens body 10. The antenna transparent substrate 210 and the lens body 10 provide mutual support, ensuring the structural stability of the transparent antenna lens 100.

[0030] The multiple first metal structures 220 are connected to each other, and the irregularly arranged polygonal metal grid formed by the surrounding elements forms the core structure of the transparent antenna 20. The irregularly arranged polygonal metal grid formed by the multiple first metal structures 220 can be understood as a mesh structure formed by irregularly arranging multiple polygonal metal grids. The irregularly arranged polygonal metal grid can efficiently conduct and radiate electromagnetic waves, thereby realizing the transmission of wireless signals and converting electrical signals into electromagnetic waves for transmission. At the same time, the irregularly arranged polygonal metal grid formed by the multiple first metal structures 220 can realize the reception of wireless signals and convert electromagnetic waves into electrical signals. Furthermore, the irregularly arranged polygonal metal grid formed by the multiple first metal structures 220 can transmit and receive wireless signals, thereby realizing the function of the transparent antenna 20.

[0031] Furthermore, the irregularly arranged polygonal metal grid formed by the interconnected and enclosing multiple first metal structures 220 is disordered and irregular in position. Consequently, when light waves pass through the irregularly arranged polygonal metal grid, the phase differences of the secondary wave sources generated at each polygonal metal grid are random, with no consistent superposition direction. When light waves pass through the irregularly arranged polygonal metal grid, interference in all directions cancels each other out, averaging the interference effect and destroying the coherent interference generated by the periodic metal grid being equivalent to a grating. Since interference is often accompanied by diffraction, the two together constitute the core phenomena of wave optics. Therefore, the irregularly arranged polygonal metal grid formed by the interconnected and enclosing multiple first metal structures 220 can achieve a more uniform light intensity distribution through the transparent antenna lens 100, reducing diffraction fringes and presenting a diffuse (also understood as scattering) effect. This solves the problem of bright diffraction fringes and dark areas caused by the superposition of wave peaks caused by the periodic metal grid.

[0032] Therefore, through the transparent antenna lens 100 provided in this application, the lens body 10 and the transparent antenna 20 are combined, and they can support each other, so that the transparent antenna 20 is set on the lens of the glasses. As a result, the design space of the transparent antenna 20 is no longer limited by the size of the temples, and it is far away from the human head, solving the problems of low electromagnetic performance caused by the human body's absorption and scattering of electromagnetic waves and size limitations, so that the electromagnetic performance of the transparent antenna 20 is greatly improved to achieve better signal coverage and transmission. In addition, the transparent antenna lens 100 provided in this application can solve the problems of bright diffraction stripes and dark areas caused by coherent interference generated by the periodic metal grid, allowing users to see clearer and more accurate images.

[0033] In some embodiments, the lens body 10 can be an optical waveguide structure, and the transparent antenna lens 100 is a waveguide lens, which can efficiently and clearly transmit virtual images (such as text, three-dimensional models, navigation information, etc.) to the user's eyes without blocking the user's field of view, while allowing real ambient light to pass through, thereby achieving a natural fusion of virtual information and real scenes, and can be applied to augmented reality glasses and virtual reality glasses.

[0034] In some embodiments, the lens body 10 can also be a base material structure of a corrective lens or a protective lens, and the transparent antenna lens 100 is a corrective lens or a protective lens. It can adjust the focusing position of light in the eyeball through optical principles to solve the problem of blurred vision, or isolate risks through physical, chemical or optical means to ensure eye safety, and can be used in corrective glasses or protective glasses.

[0035] See Figure 4 In some embodiments, the transparent antenna 20 further includes a plurality of second metal structures 230. The plurality of second metal structures 230 and the plurality of first metal structures 220 are disposed on the same surface of the antenna transparent substrate 210. At least some of the plurality of second metal structures 230 are connected to form an irregularly arranged fractured metal grid. The polygonal metal grid is disposed within the region surrounded by the fractured metal grid.

[0036] In this embodiment, multiple second metal structures 230 and multiple first metal structures 220 are arranged on the same surface of the antenna transparent substrate 210, so that the irregularly arranged polygonal metal grid formed by the multiple first metal structures 220 and the irregularly arranged broken metal grid formed by the multiple second metal structures 230 are arranged on the same surface.

[0037] The partial connection of the plurality of second metal structures 230 can cause the irregularly arranged metal grid to be broken, forming an irregularly arranged broken metal grid. The irregularly arranged broken metal grid can be understood as a irregularly arranged broken mesh structure formed by discontinuous breaks between the plurality of polygonal metal grids.

[0038] The polygonal metal grid is set within the area surrounded by the fractured metal grid, which can be understood as the fractured metal grid being set at the edge of the polygonal metal grid. The irregularly arranged fractured metal grid can disrupt the continuity of the irregularly arranged polygonal metal grid, distracting the user's attention, thereby destroying the user's eye's sensitivity to regularity and high-contrast patterns, and preventing the brain from tracking the complete outline. Therefore, by setting the polygonal metal grid within the area surrounded by the fractured metal grid, the outline of the irregularly arranged polygonal metal grid can be made less visually obvious, and the overall shape is more like a natural texture rather than a geometric shape, weakening the visibility of the irregularly arranged polygonal metal grid's outline, allowing the transparent antenna 20 to be better hidden in the transparent antenna lens 100.

[0039] See Figure 5 In some embodiments, along the extension direction of the polygonal metal grid toward the edge of the lens, as shown in FIG. Figure 6 The A-A' direction shown is the same as Figure 7 In the BB' direction shown, the density of the fractured metal grid shows a decreasing trend.

[0040] In this embodiment, multiple first metal structures 220 surround an irregularly arranged polygonal metal mesh. Multiple second metal structures 230 surround an irregularly arranged fractured metal mesh. As the polygonal metal mesh extends toward the edge of the lens, the density of the fractured metal mesh decreases, causing the individual metal cells within the fractured metal mesh to become increasingly sparse, forming a gradually changing and fractured metal mesh. The multiple second metal structures 230 surround the irregularly arranged fractured metal mesh, creating a gradual, fractured pattern that weakens the outline of the irregularly arranged polygonal metal mesh, reduces local contrast and edge sharpness, and blurs the boundaries. Furthermore, the fractured and gradually sparse mesh structure of the fractured metal mesh reduces the spatial frequency of the mesh, allowing it to blend more seamlessly with the irregularly arranged polygonal metal mesh, creating an overall appearance more like a natural texture than a geometric pattern. This reduces the visibility of the polygonal metal mesh's outline, improves visual comfort, and allows the transparent antenna 20 to be better concealed within the transparent antenna lens 100.

[0041] Figure 6 The transparent antenna lens 100 shown is Figure 7 The transparent antenna lens 100 shown can be applied to smart glasses 300, making the antenna outline of the transparent antenna 20 in the smart glasses 300 invisible and reducing diffraction stripes, thereby counteracting the diffraction of light, reducing the impact of the transparent antenna 20 on the optical performance of the smart glasses 300, and improving the user experience.

[0042] See Figure 8In some embodiments, an isolation region 211 is provided between the fractured metal grid and the polygonal metal grid.

[0043] In this embodiment, the area where the polygonal metal mesh is located is the area where the transparent antenna 20 transmits and receives wireless signals. The polygonal metal mesh is set within the area surrounded by the fractured metal mesh, and can be better hidden in the transparent antenna lens 100 due to the structural characteristics of the fractured metal mesh. The fractured metal mesh does not play a role in transmitting and receiving wireless signals. Furthermore, the fractured metal mesh is isolated from the polygonal metal mesh by the isolation area 211, which can prevent the fractured metal mesh from affecting the performance of the polygonal metal mesh in transmitting and receiving wireless signals. Therefore, by providing the isolation area 211 between the fractured metal mesh and the polygonal metal mesh, the electromagnetic performance of the transparent antenna 20 can be further improved, thereby achieving better signal coverage and transmission.

[0044] In some embodiments, the isolation region 211 can be understood as the area surrounded by the surface of the antenna transparent substrate 210, the fractured metal grid, and the polygonal metal grid. The isolation region 211 can expose the surface of the antenna transparent substrate 210. Alternatively, the fractured metal grid and the polygonal metal grid can be separated and separated from each other on the surface of the antenna transparent substrate 210, without being connected.

[0045] In some embodiments, the isolation width of the isolation region 211 is between 8 microns and 70 microns, which can be set according to the actual application scenario. The isolation width of the isolation region 211 is not limited in this application, and the isolation width of the isolation region 211 can be adaptively adjusted.

[0046] In some embodiments, the size of the irregularly arranged polygonal metal mesh can be set based on the antenna size. Antenna size can be determined based on the operating frequency band, lens size, and performance indicators (such as gain, bandwidth, stability, etc.), and can be set based on the actual application scenario.

[0047] The number of metal grids in the irregularly arranged polygonal metal grid can be set according to the requirements of transmittance and square resistance, and can be adjusted according to the actual application scenario.

[0048] The number of sides of each metal grid in the irregularly arranged polygonal metal grid can be three or more, and can be adjusted according to actual application scenarios.

[0049] In some embodiments, the density of the irregularly arranged fractured metal meshes exhibits a decreasing trend, the degree of which can be determined by a gradient strength coefficient, which can be adjusted based on the actual application scenario. The fracture condition of the irregularly arranged fractured metal meshes can be determined by the fracture radius, fracture distribution ratio, and fracture length, which can be adjusted based on the actual application scenario.

[0050] See Figure 9 In some embodiments, the transparent antenna 20 further includes a transparent cover layer 240 and a transparent connection layer 250. The transparent cover layer 240 is disposed on a surface of the antenna transparent substrate 210 and covers the plurality of first metal structures 220 and the plurality of second metal structures 230. The transparent connection layer 250 is disposed on a surface of the transparent cover layer 240 and is disposed away from the lens body 10.

[0051] In this embodiment, a transparent cover layer 240 is disposed between the antenna transparent substrate 210 and the transparent connecting layer 250. The transparent cover layer 240 covers the plurality of first metal structures 220 and the plurality of second metal structures 230, thereby covering the irregularly arranged polygonal metal grids and the fractured metal grids. This provides protection, preventing the polygonal metal grids and the fractured metal grids from physical damage, oxidation, or other external factors, thereby protecting the polygonal metal grids and the fractured metal grids from damage. Furthermore, the transparent cover layer 240 is transparent and electrically insulating, preventing short circuits and other conditions, ensuring the electromagnetic performance of the transparent antenna 20 and achieving better signal coverage and transmission.

[0052] The transparent connecting layer 250 is disposed between the transparent cover layer 240 and the first transparent protective component 30, connecting the transparent cover layer 240 and the first transparent protective component 30, thereby further strengthening the connection between the transparent cover layer 240 and the first transparent protective component 30. Thus, the transparent antenna 20 is adhered to the surface of the first transparent protective component 30 through the transparent connecting layer 250, further strengthening the connection between the transparent antenna 20 and the first transparent protective component 30.

[0053] In some embodiments, the antenna transparent substrate 210 can be made of any transparent and flexible material, such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyimide (PI), cycloolefin copolymer (COP), and polymethyl methacrylate (PMMA). Various methods, such as etching, electroplating, and nanoimprinting, can be used on the antenna transparent substrate 210 to form irregularly arranged polygonal metal grids and irregularly arranged fractured metal grids.

[0054] The transparent cover layer 240 may be made of any transparent and flexible material such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polyimide (PI).

[0055] The material of the transparent connection layer 250 may be optically clear adhesive (OCA) or optically clear resin (OCR).

[0056] See Figure 10 In some embodiments, the transparent antenna 20 further includes a first anti-reflection film layer 260 . The first anti-reflection film layer 260 and the transparent cover layer 240 are disposed on opposite sides of the antenna transparent substrate 210 .

[0057] In this embodiment, the first anti-reflection film layer 260 and the transparent cover layer 240 are disposed on opposite sides of the antenna transparent substrate 210, thereby improving the light transmittance of the transparent antenna 20 and reducing haze. Furthermore, the first anti-reflection film layer 260 improves the light transmittance of the transparent antenna 20, enhancing visual clarity. The first anti-reflection film layer 260 also reduces reflective interference from the transparent antenna 20, improving visual comfort and optimizing the viewing experience.

[0058] In some embodiments, the material of the first anti-reflection film layer 260 can be any one of an inorganic material, an organic polymer material, or a composite nanomaterial.

[0059] In some embodiments, the transparent antenna lens 100 further includes a first transparent protective component 30 . The first transparent protective component 30 is disposed on a surface of the transparent connecting layer 250 and is away from the lens body 10 .

[0060] In this embodiment, the transparent antenna 20 is adhered to the surface of the first transparent protective component 30 via the transparent connecting layer 250, thereby ensuring a more stable connection between the transparent antenna 20 and the first transparent protective component 30. The first transparent protective component 30 protects the transparent antenna 20, thereby preventing the transparent antenna lens 100 from wear and scratches, and resisting stains, corrosion, and aging, thereby extending the service life of the transparent antenna lens 100.

[0061] In some embodiments, the transparent antenna lens 100 further includes a second transparent protective component 40. The second transparent protective component 40 and the transparent antenna 20 are disposed on opposite sides of the lens body 10.

[0062] The second transparent protection component 40 is connected to the lens body 10 via a first annular connection structure 510 . The second transparent protection component 40 , the lens body 10 and the first annular connection structure 510 surround and form a first air layer 610 .

[0063] In this embodiment, the second transparent protective component 40 and the transparent antenna 20 are disposed opposite each other on opposite sides of the lens body 10, and the first transparent protective component 30 is disposed on the surface of the transparent connecting layer 250. This allows the lens body 10 and the transparent antenna 20 to be disposed between the second transparent protective component 40 and the first transparent protective component 30, thereby protecting the transparent antenna 20 and the lens body 10 from different angles. Furthermore, the second transparent protective component 40 and the first transparent protective component 30 protect the transparent antenna lens 100 from wear and scratches, and resist stains, corrosion, and aging, thereby extending the service life of the transparent antenna lens 100.

[0064] The second transparent protective assembly 40 is connected to the lens body 10 via a first annular connecting structure 510. This can be understood as a ring-shaped connecting structure disposed at the edge of the second transparent protective assembly 40, thereby connecting the second transparent protective assembly 40 to the lens body 10. The second transparent protective assembly 40, the lens body 10, and the first annular connecting structure 510 surround a first air layer 610, which satisfies the requirement for total internal reflection of light as it propagates through the lens body 10.

[0065] In one embodiment, the first annular connecting structure 510 can be a pressure-sensitive adhesive (PSA), a hot-melt pressure-sensitive adhesive (HMPSA), or a water-based pressure-sensitive adhesive. The first annular connecting structure 510 can be used to adhere the lens body 10 and the second transparent protective assembly 40 together, making the connection between the lens body 10 and the second transparent protective assembly 40 more secure.

[0066] In some embodiments, the transparent antenna 20 is connected to the lens body 10 via a second annular connection structure 520 , and the transparent antenna 20 , the lens body 10 , and the second annular connection structure 520 surround and form a second air layer 620 .

[0067] In this embodiment, the second annular connection structure 520 is identical to the first annular connection structure 510. The transparent antenna 20 is connected to the lens body 10 via the second annular connection structure 520, which can be understood as a ring-shaped connection structure provided at the edge of the lens body 10 to connect the transparent antenna 20 to the lens body 10. The transparent antenna 20, the lens body 10, and the second annular connection structure 520 surround a second air layer 620, which satisfies the requirement for total internal reflection of light traveling through the lens body 10. Furthermore, by forming the first air layer 610 and the second air layer 620 on opposite sides of the lens body 10, the requirement for total internal reflection of light traveling through the lens body 10 is met, enabling efficient and clear transmission of virtual images (e.g., text, 3D models, navigation information, etc.) to the user's eyes while allowing real ambient light to pass through, achieving a natural fusion of virtual information and real-world scenes.

[0068] See Figure 9 In some embodiments, the first transparent protection component 30 includes a first transparent protection layer 310 . The first transparent protection layer 310 is disposed on a surface of the transparent connection layer 250 , and the first transparent protection layer 310 is disposed away from the lens body 10 .

[0069] In this embodiment, the transparent antenna 20 is adhered to the surface of the first transparent protective layer 310 via the transparent connecting layer 250, thereby providing a more stable connection between the transparent antenna 20 and the first transparent protective layer 310. The first transparent protective layer 310 protects the transparent antenna 20 and the lens body 10, thereby preventing the transparent antenna lens 100 from wear and scratches, and resisting stains, corrosion, and aging, thereby extending the service life of the transparent antenna lens 100.

[0070] In some embodiments, the material of the first transparent protective layer 310 can be any material such as an organic polymer material such as polycarbonate (PC), an inorganic material such as glass, or a composite material.

[0071] In some embodiments, the second transparent protection component 40 includes a second transparent protection layer 410 . The second transparent protection layer 410 is disposed on a surface of the first annular connection structure 510 , and the second transparent protection layer 410 is disposed away from the lens body 10 .

[0072] In this embodiment, the second transparent protective layer 410 can be connected to the lens body 10 via the first annular connecting structure 510, making the connection between the second transparent protective layer 410 and the lens body 10 more stable. The second transparent protective layer 410 protects the lens body 10 and the transparent antenna 20, thereby preventing the transparent antenna lens 100 from wear and scratches, and resisting stains, corrosion, and aging, thereby extending the service life of the transparent antenna lens 100.

The third anti-reflection film layer 420 is disposed on a surface of the second transparent protective layer 410 and is away from the first annular connection structure 510 .

[0074] In this embodiment, the third anti-reflection film layer 420 and the first annular connecting structure 510 are disposed on opposite sides of the second transparent protective layer 410. The third anti-reflection film layer 420 improves the light transmittance of the second transparent protective layer 410 and reduces haze. Furthermore, the third anti-reflection film layer 420 increases the light transmittance of the second transparent protective layer 410, enhancing visual clarity. The third anti-reflection film layer 420 reduces reflective interference from the second transparent protective layer 410, improving visual comfort and optimizing the viewing experience.

[0075] In some embodiments, the material of the third anti-reflection film layer 420 can be any one of an inorganic material, an organic polymer material, or a composite nanomaterial.

[0076] In some embodiments, a third antireflection film layer 420 is formed on the surface of the second transparent protective layer 410 by magnetron sputtering, vacuum plating, coating or grinding, which can improve the transmittance and reduce the haze.

[0077] See Figure 10 In some embodiments, the first transparent protective component 30 further includes a second anti-reflection film layer 320 . The second anti-reflection film layer 320 is disposed on the surface of the first transparent protective layer 310 , and the second anti-reflection film layer 320 is disposed away from the lens body 10 .

[0078] In this embodiment, the second anti-reflection film layer 320 and the transparent connecting layer 250 are disposed on opposite sides of the first transparent protective layer 310. The second anti-reflection film layer 320 can improve the light transmittance of the first transparent protective layer 310 and reduce haze. Furthermore, the second anti-reflection film layer 320 can increase the light transmittance of the first transparent protective layer 310, thereby enhancing visual clarity. The second anti-reflection film layer 320 can also reduce light reflections from the first transparent protective layer 310, thereby improving visual comfort and enhancing the viewing experience.

[0079] In some embodiments, the material of the second anti-reflection film layer 320 can be any one of an inorganic material, an organic polymer material, or a composite nanomaterial.

[0080] In some embodiments, the second transparent protective component 40 further includes a fourth anti-reflection film layer 430 . The fourth anti-reflection film layer 430 is disposed on a surface of the second transparent protective layer 410 and is disposed close to the first annular connection structure 510 .

[0081] In this embodiment, the fourth anti-reflection film layer 430 and the third anti-reflection film layer 420 are disposed on opposite sides of the second transparent protective layer 410. The fourth anti-reflection film layer 430 is disposed between the second transparent protective layer 410 and the first annular connecting structure 510. The fourth anti-reflection film layer 430, the first annular connecting structure 510, and the lens body 10 surround a first air layer 610.

[0082] The fourth anti-reflection film layer 430 can increase the light transmittance of the second transparent protective layer 410 and reduce haze. Furthermore, the fourth anti-reflection film layer 430 can increase the light transmittance of the second transparent protective layer 410, thereby enhancing visual clarity. The fourth anti-reflection film layer 430 can reduce reflective interference from the second transparent protective layer 410, thereby improving visual comfort and optimizing the visual experience. Thus, by providing the third anti-reflection film layer 420 and the fourth anti-reflection film layer 430 on opposite sides of the second transparent protective layer 410, a double anti-reflection film layer is provided on opposite sides of the second transparent protective layer 410, further improving light transmittance and reducing reflective interference.

[0083] In some embodiments, the material of the fourth anti-reflection film layer 430 can be any one of an inorganic material, an organic polymer material, or a composite nanomaterial.
