Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0036] Refer to Figures 1 to 3 and Figure 12 , Figure 1 shows a structural diagram of the surface wave suppressor 30 and the radiation oscillator 20 of the antenna device according to an embodiment of the present application being on the same layer. Figure 2 shows a structural diagram of the feeding part 40 and the first grounding part 50 of the antenna device according to an embodiment of the present application. Figure 3 Shows Figure 1 the structure shown and Figure 2 the structure shown being superposed on each other. Figure 12 Schematically shows a cross-sectional structural view of the antenna device according to an embodiment of the present application. Among them, Figure 1 the structure shown is specifically located, for example, on the second surface 112 in Figure 12 , Figure 2 the structure shown is located, for example, in Figure 2The fourth side 132 in. An antenna device provided by an embodiment of the present application, the antenna device includes: a dielectric body 10, a radiation oscillator 20, and a surface wave suppressor 30. The radiation oscillator 20 is arranged on the dielectric body 10. The surface wave suppressor 30 is provided on the dielectric body 10, and the surface wave suppressor 30 and the radiation oscillator 20 are located on the same layer of the dielectric body 10, specifically for example Figure 12 As shown, it is located on the second side 112 of the dielectric body 10. In addition, the surface wave suppressor 30 is wound around the periphery of the radiation oscillator 20 and forms a first insulation interval region 101 with the radiation oscillator 20.

[0037] For the above antenna device, the surface wave suppressor 30 and the radiation oscillator 20 are located on the same layer of the dielectric body 10. The surface wave suppressor 30 is wound around the periphery of the radiation oscillator 20 and forms a first insulation interval region 101 with the radiation oscillator 20. In this way, the radiation oscillator 20 and the surface wave suppressor 30 coexist and are combined together, interact with each other, and participate in radiation together, solving the problem of reflection and shielding of the antenna signal by the metal film layer on the glass. At the same time, the surface wave suppressor 30 can block the surface creeping wave, thereby improving the antenna radiation efficiency and isolation.

[0038] Please refer to Figures 1 to 3 And Figure 12 , in an embodiment, the antenna device further includes a feeding part 40 and a first grounding part 50. The feeding part 40 is arranged in the peripheral area of the inner side wall of the dielectric body 10 or embedded in the peripheral area inside the dielectric body 10. The feeding part 40 is used to connect with the inner conductor 61 of the feeding wire and feed the feeding signal transmitted by the feeding wire into the radiation oscillator 20. The first grounding part 50 is arranged in the peripheral area of the inner side wall of the dielectric body 10 or embedded in the peripheral area inside the dielectric body 10. The first grounding part 50 is used to connect with the outer conductor 62 of the feeding wire. Among them, the feeding wire is, for example, a coaxial cable.

[0039] It should be noted that the outer side wall of the dielectric body 10 refers to the side wall of the dielectric body 10 facing the external environment. On the contrary, the inner side wall of the dielectric body 10 refers to the side wall of the dielectric body 10 facing the internal environment. Among them, the external environment is specifically, for example, outside the vehicle, and the internal environment is specifically, for example, inside the vehicle.

[0040] In an embodiment, the dielectric body 10 is provided with a light barrier layer. The light barrier layer is arranged in the peripheral area of the dielectric body 10. In this way, the light barrier layer has the function of blocking light and forms a shielding area 102 in the peripheral area of the dielectric body 10, specifically called a black edge area or an ink area, so as to shield the feeding part 40 and the first grounding part 50 arranged in the peripheral area of the dielectric body 10. In this way, the feeding part 40 and the first grounding part 50 are not easily observed and have better aesthetics.

[0041] Specifically, the visible light transmittance of the light barrier layer is less than or equal to 5%, more preferably less than or equal to 3%, further preferably less than or equal to 1%, even less than or equal to 0.5%, or basically 0% i.e., it is impermeable to visible light. The light barrier layer is a dark printed layer or a dark polymer film. Among them, the dark printed layer can be black or brown ceramic ink, ultraviolet ink, and is printed on the medium body 10 by processes such as screen printing and inkjet printing. In addition, the dark polymer film can be a polymer film with body coloring, for example, adding a coloring component during the manufacture of the polymer film to obtain black or brown PVB, PET, PVC, etc.; or a polymer film with surface printed pigments, for example, printing black or brown pigments on the surface of the polymer film, etc.

[0042] In addition, the medium body 10 is also provided with a visible light transmission area 103, that is, the area where the light barrier layer is not arranged. Since the light barrier layer is not arranged and the visible light transmittance of its own material is specifically, for example, any value such as 70%, 75%, 80%, 85%, 90%, 95%, etc., it can transmit visible light and is convenient for observing the situation outside the vehicle.

[0043] Specifically, please refer to Figures 1 to 3 , Figures 1 to 3 The area below the dotted line M in is also the shielding area 102, which plays a cheating role; the area above the dotted line is the visible light transmission area 103.

[0044] In one embodiment, the medium body 10 can be set as a single-layer glass plate, and the light barrier layer is located on the inner side wall of the single-layer glass plate. Of course, the medium body 10 can also be set as laminated glass. As Figure 12 shown, the laminated glass includes a first glass plate 11, an adhesive layer 12, and a second glass plate 13 that are stacked and connected in sequence. The first glass plate 11 has a first surface 111 and a second surface 112 that are opposite to each other, and the second glass plate 13 has a third surface 131 and a fourth surface 132 that are opposite to each other. The second surface 112 and the third surface 131 are oppositely arranged. The first surface 111 faces the external environment, and the fourth surface 132 faces the internal environment.

[0045] In one embodiment, the light barrier layer can be arranged on the second surface 112, the third surface 131, or the fourth surface 132.

[0046] In one embodiment, the adhesive layer 12 can be selected from polyvinyl butyral (PVB), polycarbonate (PC), sound-insulating PVB, light-shielding tape PVB, heat-control PVB, ethylene-vinyl acetate (EVA), thermoplastic polyurethane (TPU), ionomer, thermoplastic material, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyvinyl chloride (PVC), polyvinyl fluoride (PVF), polyacrylate (PA), polymethyl methacrylate (PMMA), polyurethane (PUR), and their combinations, etc.

[0047] In some embodiments, the feeding part 40 and the first grounding part 50 are independently arranged according to actual requirements. They can be located in the shielding area 102 on the inner side wall of the dielectric body 10, that is, on the shielding area 102 arranged on the fourth surface 132. For example Figure 2 and Figure 12 as shown; or they can be embedded in the shielding area 102 inside the dielectric body 10, that is, on the shielding area 102 arranged on the second surface or the third surface. In this embodiment, specifically, taking the feeding part 40 and the first grounding part 50 both being arranged in the shielding area 102 on the inner side wall of the dielectric body 10, that is, on the shielding area 102 arranged on the fourth surface 132 as an example for elaboration, but not limited thereto. Specifically, silver paste is brushed on the shielding area 102 of the fourth surface 132, and the first grounding part 50 and the feeding part 40 of the antenna are sintered. The braided layer of the feeding wire, that is, the outer conductor 62, is welded to the first docking part, and the core wire of the feeding wire, that is, the inner conductor 61, is welded to the feeding part 40; and the coupling part 21 of the feeding part 40 and the radiation oscillator 20 is aligned. Energy is coupled to the radiation oscillator 20 through the feeding part 40, so that the radiation oscillator 20 and the first grounding part 50 on the fourth surface 132 form the positive and negative poles of the antenna, effectively radiating the signal out of the glass without being reflected or shielded by the film layer, realizing ultra-wideband coverage of the 5G antenna. In addition, the feeding wire is directly led out from the fourth surface 132, connected to the communication equipment inside the vehicle, and the welding points on the fourth surface 132 are covered with a plastic shell and sealed with glue to play a protective role and improve the reliability of the antenna.

[0048] It should be noted that the alignment of the coupling part 21 of the feeding part 40 and the radiation oscillator 20 means that at least some areas overlap in the thickness direction of the dielectric body 10. As an example, the coupling part 21 of the radiation oscillator 20 is placed directly above the connection part of the feeding part 40 and the inner conductor 61, and at least one side of the coupling part 21 of the radiation oscillator 20 is aligned with the feeding part 40. For example, as Figure 3As shown, when the connection part between the feeding part 40 and the inner conductor 61 is located at the lower left corner of the feeding part 40, the lower left corner of the radiation oscillator 20 is aligned with the lower left corner of the feeding part 40, that is, the left side of the coupling part 21 in the radiation oscillator 20 is aligned with the left side of the feeding part 40, and the lower side of the coupling part 21 is aligned with the lower side of the feeding part 40.

[0049] Optionally, the radiation oscillator 20 includes one or more radiation branches, and the specific quantity can be flexibly adjusted according to actual requirements and will not be limited herein. Among them, on the premise of ensuring the antenna performance, the shape of the radiation branches can be flexibly adjusted and designed according to actual requirements. For example, the shape of each radiation branch can be rectangular; for another example, it can be designed into the shape of the manufacturer's trademark, or logos such as enterprise / product LOGO, so as to solve the problems of signal shielding and logo setting at the same time; it can also be set to other shapes and will not be limited herein. In addition, if the electrical length of the designed letter or pattern is too long, for example, laser film removal technology can be used to interrupt the redundant parts on the radiation branches. Specifically, for example, Figure 4 as shown, two interruption notches 22 formed after the interruption treatment can be achieved, so as to realize the arbitrary deformation of the antenna pattern and achieve the effect of beautifying the antenna in the transparent area.

[0050] Optionally, according to the wave velocity formula V (wave velocity) = λ (wavelength) * f (frequency), in the same medium, the wave propagation speed is the same, and the product of the wavelength and frequency remains unchanged. Therefore, λ = v / f, and the wavelength and frequency are inversely proportional, that is, the higher the frequency, the shorter the wavelength. Thus, by adjusting the electrical length of each radiation branch, the frequency band size can be correspondingly adjusted. Specifically, in this embodiment, there are three radiation branches, for example, a high-frequency radiation branch, an intermediate-frequency radiation branch, and a low-frequency radiation branch. The high-frequency band of the high-frequency radiation branch is, for example, the 3300 MHz - 5000 MHz band, the intermediate-frequency band of the intermediate-frequency radiation branch is, for example, the 1700 MHz - 2700 MHz band, and the low-frequency band of the low-frequency radiation branch is, for example, the 698 MHz - 960 MHz band.

[0051] Please refer to Figure 13 , Figure 13The Voltage Standing Wave Radio (VSWR) diagram of the above-mentioned radiation oscillator 20 combined with sheet metal design is shown. The abscissa is frequency, and the ordinate is the VSWR. The VSWR corresponding to the transparent radiation oscillator 20 at different frequencies is given in the diagram. The VSWR of the above two transparent radiation oscillators 20 can be below 3 when the frequency is 698 MHz - 960 MHz / 1710 MHz - 2700 MHz / 3300 MHz - 5000 MHz, meeting the performance requirements of the VSWR of vehicle-mounted antennas, and the radiation efficiency is greater than 50% when the frequency is 698 MHz - 960 MHz / 1710 MHz - 2700 MHz / 3300 MHz - 5000 MHz.

[0052] In addition, it should be noted that the surface wave suppressor 30 includes, but is not limited to, a metal film layer plated on, printed on, or adhered to the dielectric body 10. Specifically, the metal film layer is a light-transmitting film layer, and the light transmittance of the light-transmitting film layer includes, but is not limited to, more than 70%, specifically, for example, 70%, 75%, 80%, 85%, or 90%, etc. Thus, when the dielectric body 10 is a glass substrate, the surface wave suppressor 30 will not affect the line of sight. In addition, the metal film layer in this embodiment can be either a pure metal film layer, a metal alloy layer, or a metal oxide film layer, etc., and can be flexibly adjusted and selected according to actual needs, which will not be limited here.

[0053] In some embodiments, the radiation oscillator 20 is, for example, set as a transparent radiation oscillator 20. The specific material is, for example, the same as that of the metal film layer. The radiation oscillator 20 can be processed on the basis of the metal film layer by, for example, laser etching, which has a high processing efficiency. The dielectric body 10 serves as the carrier of the radiation oscillator 20. Since the radiation oscillator 20 is a transparent radiation oscillator 20, it can be deeply laid out in the middle position of the dielectric body 10 or any other visible light transmission area 103. The feeding part 40 and the first grounding part 50 are arranged in the shielding area 102 of the dielectric body 10, so that the radiation oscillator 20 is far from the body sheet metal part 80 at the edge of the dielectric body 10, which can reduce the interference of the body sheet metal part 80 on the radiation oscillator 20. In addition, when the radiation oscillator 20 is specifically arranged inside the dielectric body 10, the radiation oscillator 20 can be effectively protected from being scratched, corroded, oxidized, etc. At the same time, the radiation oscillator 20 is a transparent radiation oscillator 20, and the transparent radiation oscillator 20 has good conformal property and concealment, breaking the limitation of the installation position of the radiation oscillator 20, improving the overall performance of the machine, and increasing the communication distance of the vehicle networking. This means that when automobile manufacturers develop new models, they do not have to make design concessions for the antenna, ensuring the performance and beauty of the automobile and improving the user experience.

[0054] In some embodiments, in order to feed the feed signal transmitted by the feeder line into the radiation oscillator 20, the feeding section 40 can either be directly electrically connected to the radiation oscillator 20 or feed the radiation oscillator 20 by coupling. Specifically, for example, they are respectively arranged on different layers of the dielectric body 10 and are coupled and fed in a manner of being aligned with each other along the thickness direction of the dielectric body 10.

[0055] Optionally, the surface wave suppressor 30 and the radiation oscillator 20 are independently arranged and can be arranged on the first surface 111, the second surface 112, the third surface 131 or the fourth surface 132 according to actual requirements. Specifically, for example, it is a 2-layer silver material, a 3-layer silver material or a 4-layer silver material plated on the second surface 112, which is not limited herein. Of course, it can also be to provide a PET substrate, form the surface wave suppressor 30 and the radiation oscillator 20 on the PET substrate, and attach the PET substrate to the second surface 112; or it can be to set the surface wave suppressor 30 and the radiation oscillator 20 on the second surface 112 by printing. In this embodiment, specifically, a transparent silver material is electroplated into the dielectric body 10 to form the transparent surface wave suppressor 30 and the radiation oscillator 20, and the electroplating thickness of the transparent silver material is adjusted to ensure that the standing wave ratio, radiation efficiency and gain of the antenna meet the specification requirements. At the same time, the light transmittance of the surface of the transparent surface wave suppressor 30 and the radiation oscillator 20 needs to be greater than the preset light transmittance to meet the vehicle specification transparency requirements. For example, the light transmittance of the surface of the transparent surface wave suppressor 30 and the radiation oscillator 20 is preferably greater than 70%.

[0056] Please refer to Figures 1 to 3 and Figure 9 , in the actual manufacturing process, for example, a transparent metal film layer is plated on the second surface 112 of the dielectric body 10, and various differently shaped radiation oscillators 20 and surface wave suppressors 30 are engraved on the metal film layer near the shielding area 102 of the dielectric body 10 by means of laser or the like, so that various differently shaped radiation oscillators 20 and surface wave suppressors 30 coexist, combine together, interact with each other and participate in radiation together, solving the problem of reflection and shielding of the antenna signal by the metal film layer on the glass. At the same time, the metal film layer that is not removed by laser around the radiation oscillator 20 is equivalent to the surface wave suppressor 30, which can block the creeping wave on the glass surface and improve the antenna radiation efficiency and isolation. In addition, since the radiation oscillator 20 is a transparent metal film layer on the dielectric body 10, it can be arranged at any position of the dielectric body 10 as needed, making the radiation oscillator 20 as far away as possible from the body sheet metal part 80 at the edge of the dielectric body 10, reducing the adverse effect of the body sheet metal part 80 on the radiation oscillator 20, improving the anti-sheet metal interference ability of the antenna, expanding the layout range of the antenna, realizing the distributed layout of various antennas, and optimizing the isolation and radiation pattern between them.

[0057] Please refer to Figure 5 andFigure 6 , in one embodiment, the antenna device further includes a second grounding portion 70. The second grounding portion 70 is disposed in the first insulating spacer 101. The second grounding portion 70 has opposite ends, and at least one end of the second grounding portion 70 is fed and connected to the first grounding portion 50. The grounding structure formed by the combination of the second grounding portion 70 and the first grounding portion 50 is arranged circumferentially around the radiation element 20. A second insulating spacer 104 is formed between the second grounding portion 70 and the radiation element 20, and a third insulating spacer 105 is provided between the second grounding portion 70 and the surface wave suppressor 30. Thus, on the one hand, since the second grounding portion 70 is disposed in the first insulating spacer 101 and the grounding structure formed by the combination of the second grounding portion 70 and the first grounding portion 50 is arranged circumferentially around the radiation element 20, that is, the grounding structure can be arranged circumferentially around the radiation element 20. Compared with being only arranged in the edge region, not only the bandwidth is greatly expanded, but also the lateral dimension of the first grounding portion 50 can be reduced to a certain extent, making the overall structure layout more compact and the overall volume size smaller. On the other hand, the surface wave suppressor 30 can still play a role in blocking the surface creeping wave, thereby improving the antenna radiation efficiency and isolation. Moreover, since the second grounding portion 70 is located between the radiation element 20 and the surface wave suppressor 30, the second insulating spacer 104 and the third insulating spacer 105 are formed, that is, the second grounding portion 70 is not electrically connected to the radiation element 20 and the surface wave suppressor 30, so that the influence of the surface wave suppressor 30 on the performance of the antenna can be reduced, preventing the surface wave suppressor 30 from having an adverse impact on the performance of the antenna, and improving the stability of the antenna.

[0058] In some embodiments, one end of the second grounding portion 70 can be fed and connected to the first grounding portion 50, and the other end is not fed and connected to the first grounding portion 50; or the opposite ends of the second grounding portion 70 can be respectively fed and connected to the opposite ends of the first grounding portion 50, so as to improve the bandwidth, make the layout compact, and the stability of the antenna is better at the same time.

[0059] Please refer to Figure 5 and Figure 6 , in one embodiment, the second grounding portion 70 includes a main body 71 and two docking ends 72 provided at opposite ends of the main body 71. The two docking ends 72 are respectively fed and connected to the opposite ends of the first grounding portion 50.

[0060] It should be noted that the fed connection can be specifically a direct electrical connection or a coupled feed. Specifically, for example, one docking end 72 is directly electrically connected to one end of the first grounding portion 50, that is, directly connected together; the other docking end 72 is, for example, coupled to the other end of the first grounding portion 50, that is, there is a small spacing space therebetween, so that the two are coupled to feed and transmit energy.

[0061] In some embodiments, the peripheral region of the dielectric body 10 includes a shielding region 102, that is, at least a part of the peripheral region of the dielectric body 10 forms the shielding region 102 by providing a light-blocking layer. In addition, the dielectric body 10 is further provided with a visible light transmission region 103, that is, a region on the dielectric body 10 where no light-blocking layer is provided. The shielding region 102 is located on the periphery of the visible light transmission region 103. Among them, both docking ends 72 are located in the shielding region 102 of the dielectric body 10, so that it is convenient to be respectively fed and connected to the opposite ends of the first grounding portion 50. In addition, the main body 71 is located in the visible light transmission region 103 of the dielectric body 10. Specifically, the main body 71 or the second grounding portion 70 is provided as a transparent grounding portion, so that it is not easily observed in the visible region.

[0062] In some embodiments, the second grounding portion 70 and the radiation oscillator 20 can be located on the same layer of the dielectric body 10, specifically as Figure 5 shown. In this way, during processing, the second grounding portion 70, the radiation oscillator 20, and the surface wave suppressor 30 can be processed synchronously to obtain a higher production efficiency. Of course, the second grounding portion 70 and the radiation oscillator 20 can also be located on different layers of the dielectric body 10. For example, the radiation oscillator 20 and the surface wave suppressor 30 are arranged on the second surface 112, and the second grounding portion 70 is arranged on the first surface 111, the third surface 131, or the fourth surface 132, and the projection of the second grounding portion 70 in the thickness direction of the dielectric body 10 is located in the first insulation interval region 101.

[0063] Optionally, the metal film layer corresponding to the first insulation interval region 101 is, for example, engraved or etched, so that the radiation oscillator 20 and the surface wave suppressor 30 are insulated from each other, and at the same time, a color difference exists between the first insulation interval region 101 and the surface suppressor and the radiation oscillator 20 respectively. This color difference becomes obvious when the size of the first insulation interval region 101 increases.

[0064] Please refer to Figure 7 and Figure 8 , in one embodiment, the antenna device further includes a color difference adjustment member 90. The color difference adjustment member 90 is disposed in the first insulation interval region 101. In this way, after the color difference adjustment member 90 compensates and adjusts the color difference, the color difference between the first insulation interval region 101 and other regions of the dielectric body 10 can be reduced, so that the appearance of the product can be improved.

[0065] In some embodiments, the color difference adjustment member 90 is a transparent metal film layer, and the visible light transmittance is specifically, for example, 70% or more, including but not limited to 70%, 75%, 80%, 85% or 90%, etc. In this way, the color difference between the first insulating spacer 101 and other regions of the dielectric body 10 can be reduced. In addition, the color difference adjustment member 90 is insulated from the surface wave suppressor 30 and the radiation oscillator 20 respectively to prevent short-circuit defects caused by mutual electrical connection.

[0066] In some embodiments, the color difference adjustment member 90 includes a plurality of units 91 arranged in an array on the dielectric body 10. By adjusting the area size of each unit 91 and the spacing size between adjacent units 91, the visible light transmittance of the color difference adjustment member 90 can be correspondingly adjusted, thereby playing a role in improving the color difference. Optionally, the contour shape of each unit 91 includes but is not limited to regular shapes such as circles, ellipses, polygons, and other irregular shapes. Among them, the polygon is, for example, a rectangle, a pentagon, etc., and can be specifically adjusted and set flexibly according to actual needs.

[0067] Among them, the deviation between the visible light transmittance of the color difference adjustment member 90 and the visible light transmittance of the surface wave suppressor 30 is within a first preset range, and the deviation between the visible light transmittance of the color difference adjustment member 90 and the visible light transmittance of the radiation oscillator 20 is within a second preset range. The first preset range and the second preset range are independently adjusted and set according to actual needs, and are not limited herein as long as the color differences among the three are small and not easily distinguishable.

[0068] Specifically, the color difference adjustment member 90, the radiation oscillator 20, and the surface wave suppressor 30 all adopt metal film layers with the same visible light transmittance, and are synchronously processed on the dielectric body 10 by various film removal techniques such as laser, etc., with high processing efficiency.

[0069] In some embodiments, when the second grounding portion 70 is provided, the color difference adjustment member 90 can also be correspondingly arranged at positions corresponding to the second insulating spacer 104 and the third insulating spacer 105 respectively, that is, the color difference adjustment member 90 is respectively arranged in the second insulating spacer 104 and the third insulating spacer 105 to reduce the color difference, or the color difference adjustment member 90 is arranged on other layers of the dielectric body 10, so that the projection of the color difference adjustment member 90 in the thickness direction of the dielectric body 10 is located in the second insulating spacer 104 and the third insulating spacer 105.

[0070] In some embodiments, please refer to Figure 3 or Figure 6, the first grounding portion 50 is, for example, arranged at an insulating interval from the surface wave suppressor 30, so as to avoid the adverse effect on the antenna performance caused by the excessively large area size of the surface wave suppressor 30 after the surface wave suppressor 30 is fed and connected to the first grounding portion 50, and reduce the antenna performance. Further, since the surface wave suppressor 30 is not connected to the first grounding portion 50, the surface wave suppressor 30 can be arranged at a position other than the radiation oscillator 20 in the visible light transmission area 103 of the dielectric body 10, covering as many areas of the visible light transmission area 103 of the dielectric body 10 as possible, so as to have a good heat insulation effect, and can also extend to the shielding area 102 of the dielectric body 10.

[0071] Of course, in some other embodiments, please refer to Figure 10 and Figure 11 , at least one end of the first grounding portion 50 is fed and connected to the surface wave suppressor 30. Specifically, the opposite ends of the first grounding portion 50 are respectively fed and connected to the surface wave suppressor 30. In this way, the surface wave suppressor 30 relative to the grounding portion, specifically, such as the second grounding portion 70 in the above embodiment, can not only suppress surface waves, improve radiation efficiency, and improve performance stability, but also, due to the grounding structure formed by the combination of the surface wave suppressor 30 and the first grounding portion 50 being arranged around the circumference of the radiation oscillator 20, that is, the grounding structure can be arranged around the circumference of the radiation oscillator 20. Compared with being only arranged in the edge area, it not only greatly expands the bandwidth, but also can reduce the lateral size of the first grounding portion 50 to a certain extent, making the overall structure arrangement more compact and the overall volume size smaller. Further, in order to avoid the adverse effect on the antenna performance caused by the excessively large area size of the surface wave suppressor 30, the area size of the surface wave suppressor 30 does not need to be designed too large, and it does not need to cover the entire surface of the visible light transmission area 103, and specifically, it can be arranged in a strip shape around the radiation oscillator 20.

[0072] Please refer to Figures 1 to 3 , in one embodiment, a device includes the antenna device of any of the above embodiments.

[0073] In the above device, the surface wave suppressor 30 and the radiation oscillator 20 are located on the same layer of the dielectric body 10. The surface wave suppressor 30 is wound around the periphery of the radiation oscillator 20 and forms a first insulation interval area 101 with the radiation oscillator 20. In this way, the radiation oscillator 20 and the surface wave suppressor 30 coexist and are combined together, interact with each other, and participate in radiation together, solving the problem of reflection and shielding of the antenna signal by the metal film layer on the glass. At the same time, the surface wave suppressor 30 can block the surface creeping wave, thereby improving the antenna radiation efficiency and isolation.

When the vehicle takes an automobile as an example, the dielectric body 10 includes, but is not limited to, being on the front windshield, rear windshield, corner window, skylight, left and right side windows, etc.
