[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] In this application, 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0039] In this application, unless otherwise clearly specified and limited, the term "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0040] In addition, it should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may be an element in the middle.

[0041] The development of intelligent networking of automobiles has made the introduction of vehicle-mounted antennas inevitable. The function of vehicle-mounted antennas is to enable communication between the car and surrounding vehicles, people, and transportation infrastructure.

[0042] To ensure reliable communication between the car and surrounding vehicles, people, and transportation infrastructure, the vehicle-mounted antenna needs to have omnidirectional radiation capabilities. However, directly installing a vehicle-mounted antenna with omnidirectional radiation performance inside the car is easily interfered by the body sheet metal and other active devices, resulting in the inability to achieve true omnidirectional radiation. Therefore, how to achieve omnidirectional radiation of the vehicle has become a problem that needs to be solved urgently.

[0043] At present, the types and quantities of vehicle-mounted antennas have increased significantly, from the original 1 GPS (Global Positioning System) plus 2 4G antennas to 4 5G antennas plus 1 or 2 GPS or GNSS (Global Navigation Satellite System) antennas plus 2 V2X (Vehicle-to Everything) antennas. Some models will also be equipped with Wi-Fi (Wireless Fidelity) and UWB (Ultra Wide Band) antennas.

[0044] Currently, the commonly used vehicle antenna solutions mainly include placing a box antenna on the center console below the front windshield, placing a box antenna on the rear spoiler of an SUV (English full name: Sport Utility Vehicle, Chinese: Sports Utility Vehicle), or splitting the box antenna into several parts and placing them in different positions on the sunroof and external shark fins.

[0045] However, the box antenna is large in size, the installation location is easily restricted, and the radiation performance is easily affected by the environment inside the car. This is because when the electromagnetic waves generated by the antenna are radiated outside the car, they need to first pass through the packaging shell, then the interior panel (sheet metal) or center console, and then pass through the window glass.

[0046] In addition, when the antenna is currently attached to the edge of the vehicle window glass by using a bracket or gluing, for functional vehicle window glass, such as glass with a coating or Low-E (English full name: Low Emissivity, Chinese: Low radiation) film, due to the low anti-interference ability of the existing antenna, it is generally necessary to remove the Low-E film layer on the vehicle window glass over a large area (open the window) so that the antenna is at a certain distance from the Low-E film layer to reduce the impact of the Low-E film layer on the antenna radiation performance. However, there is a certain difference in appearance between the film-removed area and the non-film-removed area, and the film-removed area is often required to be covered with a shielding layer. Therefore, when the film-removed area is larger, the range of the shielding layer required on the vehicle window glass is larger, resulting in a significant reduction in the effect of the functional vehicle window glass.

[0047] Based on this, it is necessary to adopt effective technical means to achieve omnidirectional radiation of the vehicle, as well as an antenna with strong anti-interference ability. The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0048] In one embodiment, as shown in FIG1 , a structural diagram of an antenna glass is provided, the antenna glass includes a vehicle window glass 100 and an antenna 200, the antenna 200 is disposed on the vehicle window glass 100, wherein the antenna 200 includes: a first radiator 110; and at least one second radiator 120, each second radiator 120 is disposed around the outside of the first radiator 110, and each second radiator 120 has a gap with the first radiator 110. FIG1 takes one second radiator as an example.

[0049] When there are multiple second radiators 120, the multiple second radiators 120 can be arranged in sequence with intervals around them. For example, there are three second radiators 120, which are respectively denoted as T1, T2, and T3. Then T1 is arranged around the outside of the first radiator 110, T2 is arranged around the outside of T1, and T3 is arranged around the outside of T2. There are gaps between T1 and the first radiator 110, between T2 and T1, and between T3 and T2.

[0050] The first radiator 110 may be a parasitic patch, and its shape may be circular or rectangular. A circular shape is used as an example in FIG. 1 . In addition, the shape of the first radiator 110 may also be an ellipse or a polygon (regular polygon), etc. Preferably, the first radiator 110 is circular, which can improve the omnidirectionality of the radiation of the antenna 200. It should be noted that the shape of the first radiator 110 listed here does not limit whether the first radiator 110 is solid or hollow. For example, the first radiator may be a solid circle or a hollow circle (that is, a ring).

[0051] The second radiator 120 may also be a parasitic patch, and its shape may be circular or rectangular, and the second radiator 120 is arranged around the outside of the first radiator 110, so the second radiator 120 is a ring radiator, that is, the second radiator 120 may be a ring or a rectangular ring, and a ring is used as an example in FIG1 , and the second radiator 120 may also be an elliptical ring or a polygonal ring. Preferably, the second radiator 120 is a ring, which can improve the omnidirectionality of the radiation of the antenna 200.

[0052] There are two feeding methods for the antenna 200: the first method is to feed the first radiator 110 and the second radiator 120 close to the first radiator 110 at the same time; the second method is to feed only the second radiator 120 close to the first radiator 110. Compared with the second feeding method, the first feeding method has better omnidirectional radiation performance of the antenna 200.

[0053] In addition, the vehicle window glass member 100 may be any one of a sunroof glass, front and rear windshields, and triangular window glass. Preferably, a sunroof glass is selected.

[0054] The vehicle window glass component 100 includes a first glass component, an intermediate layer and a second glass component. The first glass component includes a first surface and a second surface opposite to the first surface, and the second glass component includes a third surface and a fourth surface opposite to the third surface, and the fourth surface faces the interior of the vehicle. The intermediate layer is arranged between the second surface and the third surface, and the intermediate layer material can be selected from PVB (full name in English: Polyvinyl Butyral, Chinese: Polyvinyl Butyral), which is used to bond the first glass component and the second glass component, and can effectively improve the strength and toughness of the vehicle window glass component, and can also improve the collision resistance and safety performance of the vehicle window glass component.

[0055] The above-mentioned antenna glass includes a vehicle window glass component 100 and an antenna 200, wherein the antenna 200 is arranged on the vehicle window glass component 100, wherein the antenna 200 includes: a first radiator 110 and at least one second radiator 120, each second radiator 120 is arranged around the outside of the first radiator 110, and there is a gap between each second radiator 120 and the first radiator 110, so that after the second radiator 120 and / or the first radiator 110 are fed, the antenna 200 will radiate outward in all directions of 360°, thereby realizing omnidirectional radiation, and because the antenna 200 is arranged on the vehicle window glass component 100, the antenna 200 is not easily interfered by the body sheet metal and other active devices, so that the antenna glass can achieve the purpose of omnidirectional radiation.

[0056] In one embodiment, the antenna 200 includes a second radiator 120. Based on the above two feeding methods, the present application proposes two antenna structures, as shown in FIG. 2 and FIG. 3 respectively.

[0057] 2 , the second radiator 120 is disposed in a closed manner around the outside of the first radiator 110, and a feeding port 130 is disposed between the second radiator 120 and the first radiator 110. The feeding port 130 is used to connect to a feed source.

[0058] 3 , the second radiator 120 is disposed in a non-enclosed manner around the outside of the first radiator 110 , and a feeding port 130 is disposed at an open end of the second radiator 120 .

[0059] In one embodiment, at least one second radiator includes a proximal radiator and a distal radiator, that is, the number of second radiators in the antenna 200 is two, the proximal radiator is arranged around the outside of the first radiator; the distal radiator is arranged around the outside of the proximal radiator and there is a gap between the proximal radiator and the distal radiator.

[0060] Based on the above two feeding methods, the present application also proposes two other antenna structures, as shown in FIG. 4 and FIG. 5 respectively.

[0061] 4 , the proximal radiator 121 is disposed outside the first radiator 110 in a closed manner, and a feeding port 130 is disposed between the proximal radiator 121 and the first radiator 110. The distal radiator 122 is disposed outside the proximal radiator 121 in a closed manner, and there is a gap between the distal radiator 122 and the proximal radiator 121.

[0062] 5 , the proximal radiator 121 is disposed in an open manner outside the first radiator 110 , and a feeding port 130 is disposed at the open end of the proximal radiator 121 . The distal radiator 122 is disposed in an open manner outside the proximal radiator 121 , and there is a gap between the distal radiator 122 and the proximal radiator 121 .

[0063] Taking the antenna structure shown in FIG5 as an example, the return loss diagram of the antenna is shown in FIG6 . It can be seen that the resonant frequency band of the antenna is 5.2 to 6 GHz, which meets the standard index of 5.905 to 5.925 GHz and complies with the antenna design specification.

[0064] The 2D diagram of the horizontal radiation direction of the antenna within the range of 80°~100° elevation angle is shown in Figure 7. Taking the -180° direction in the figure as the reference point, the four curves from bottom to top correspond to the elevation angles of 100°, 96°, 90° and 80° respectively. It can be seen that the antenna can achieve omnidirectional radiation, but at the same time, the radiation direction of the antenna is slightly tilted downward. In fact, the simulation is a single antenna model. In actual use, the antenna is located in the black edge area of ​​the window glass. There are sheet metal parts in the near area inside the car, which will have a greater impact on the radiation direction of the antenna, so that the ground radiation direction is adjusted to the horizontal and slightly upward direction, so that the antenna can meet the functional requirements of the vehicle network in actual use.

[0065] The current distribution diagram on the antenna surface is shown in FIG8 , which is obtained by simulation when the resonant frequency of the antenna is 5.9 GHz. The length of the arrow in the figure represents the magnitude of the current, and the density of the arrow represents the current density. It can be seen from the current distribution diagram that the current is mainly distributed between the inner circle gap and the outer circle gap, that is, the current is mainly distributed between the gap formed by the first radiator 110 and the proximal radiator 121 and the gap formed by the proximal radiator 121 and the distal radiator 122. In other words, the resonant frequency of 5.9 GHz is generated by the fundamental mode of the inner circle gap and the high-order mode of the outer circle gap. The outer ring (distal radiator 122) can improve the gain of the antenna at 5.9 GHz through the high-order mode, and can also improve the antenna horizontal plane radiation pattern by affecting the uniformity of the current distribution.

[0066] The antenna in this embodiment includes a first radiator 110, a proximal radiator 121 and a distal radiator 122. The proximal radiator 121 is arranged around the outside of the first radiator 110; the distal radiator 122 is arranged around the outside of the proximal radiator 121, and there is a gap with the proximal radiator 120. In this way, whether the antenna is fed by the feeding port 130 in Figure 4 or the feeding port 130 in Figure 5, the current will be mainly distributed between the gap formed by the first radiator 110 and the proximal radiator 121 and the gap formed by the proximal radiator 121 and the distal radiator 122. Since the distal radiator 122 surrounds the first radiator 110 and the proximal radiator 121, it can block the Low-E film layer from absorbing the electromagnetic waves radiated by the antenna. Therefore, the antenna in this embodiment not only has omnidirectional radiation, but also has strong anti-interference ability.

[0067] In one embodiment, at least one of the first radiator 110 , the proximal radiator 121 , and the distal radiator 122 is composed of a plurality of coupling branches.

[0068] Optionally, the first radiator 110 may be formed by splicing two coupling branches in the shape of a half ring; the proximal radiator 121 is a ring radiator, which includes a plurality of coupling branches, and there is a gap between the opposite ends of any two adjacent coupling branches, wherein a feeding port 130 is provided at the opposite ends of at least one of any two adjacent coupling branches, and / or a feeding port is provided between at least one coupling branch and the first radiator. The distal radiator 122 may be composed of a plurality of coupling branches in the shape of a circular ring.

[0069] Exemplarily, as shown in Figure 9, a structural diagram of another antenna is provided, wherein the first radiator 110 is circular, the proximal radiator 121 includes a plurality of coupling branches, there is a gap between the opposite ends of any two adjacent coupling branches, wherein a feeding port 130 is arranged between at least one coupling branch and the first radiator 110, and the distal radiator 122 is a circular ring.

[0070] Exemplarily, as shown in Figure 10, a structural diagram of another antenna is provided, wherein the first radiator 110 is circular, the proximal radiator 121 includes a plurality of coupling branches, there is a gap between the opposite ends of any two adjacent coupling branches, wherein a feeding port 130 is set at the opposite ends of at least one of any two adjacent coupling branches, and the distal radiator 122 is a circular ring.

[0071] In addition, it should be noted that the UWB (English full name: Ultra Wide Band, Chinese: ultra-wideband) function can be achieved by adjusting the size of any antenna in the above Figures 1, 2, 3, 4, 5, 9 and 10.

[0072] In one embodiment, as shown in FIG11 , the present application provides another antenna glass, in which the antenna 200 is taken as the antenna example in FIG5 , and the antenna 200 is arranged on the fourth surface of the vehicle window glass piece 100 , and is arranged in the black border area (shielding layer) on the fourth surface of the vehicle window glass piece 100 , so that the light transmittance of the transparent area of ​​the vehicle window glass piece is not affected, and the strength of the glass itself is not affected.

[0073] In addition, a plurality of antennas 200 may be disposed on the vehicle window glass member 100, so that omnidirectional radiation may be enhanced.

[0074] In one embodiment, the antenna glass further includes a conductive layer disposed on the vehicle window glass member, wherein the conductive layer surrounds the antenna.

[0075] The conductive layer may be a Low-E film, a silver-plated film or a copper film, etc. For example, the conductive layer may be a Low-E film, which is a film product composed of multiple layers of metal or other compounds plated on the surface of a glass carrier, and has high transmittance to visible light and high reflectivity to mid- and far-infrared rays, so that the glass carrier can have excellent thermal properties and good optical properties.

[0076] The conductive layer is generally disposed on the second surface and / or the fourth surface of the vehicle window glass piece.

[0077] Optionally, the conductive layer and the antenna are in the same plane, and the distance between the conductive layer and the antenna can be 0, that is, the distance between the outermost side of the antenna and the conductive layer is 0. This can be achieved by opening a window in the conductive layer, the size of the window being the size of the antenna, and then arranging the antenna at the position of the window, so that the distance between the conductive layer and the antenna is 0.

[0078] The distance between the conductive layer and the antenna can also be greater than or equal to half the wavelength of the antenna's resonant frequency, that is, the distance between the outermost side of the antenna and the conductive layer is not less than half the wavelength of the antenna's resonant frequency. This can be achieved by opening a window in the conductive layer. If the antenna is circular, when the shape of the window is also circular, the radius of the window must be greater than or equal to half the wavelength of the antenna's resonant frequency. For example, the antenna wire diameter is 44mm, that is, the window size is about 76mm; when the shape of the window is rectangular, the minimum distance from any side of the rectangle to the outermost side of the antenna must be no less than half the wavelength of the antenna's resonant frequency. In short, the minimum distance from the edge of the window to the antenna must be no less than half the wavelength of the antenna's resonant frequency.

[0079] In this embodiment, due to the special structure of the antenna in the present application, it can reduce the absorption of the Low-E film layer on the electromagnetic waves radiated by the antenna. Therefore, the distance between the conductive layer and the antenna can be selected to be 0. However, in order to avoid the situation where the Low-E film layer cannot completely block the absorption of the electromagnetic waves radiated by the antenna, it is recommended to select a distance between the conductive layer and the antenna that is greater than or equal to half the wavelength of the antenna resonant frequency. In order to avoid the conductive layer window size being too large, preferably, the distance between the conductive layer and the antenna is half the wavelength of the antenna resonant frequency.

[0080] Compared with the size of the conductive layer window currently on the market, in this application, due to the special structure of the antenna, the size of the conductive layer window is smaller, so the range of the shielding layer required on the window glass is small, which has little impact on the functionalized window glass.

[0081] In one embodiment, as shown in FIG. 12 , the present application further provides a vehicle, the vehicle comprising the antenna glass described in any one of the above antenna glass embodiments; the vehicle further comprises a sheet metal part 1201 , and there is a gap between the sheet metal part 1201 and the antenna in the antenna glass.

[0082] In which, taking the window glass member 100 in the antenna glass as a sunroof glass as an example, the sheet metal member 1201 is the sheet metal member below the black border region on the fourth surface of the window glass member 100. When the antenna is arranged in the black border region on the fourth surface, the positional arrangement relationship between the sheet metal member 1201 and the antenna may be as follows:

[0083] The first type is that the antenna does not overlap with the sheet metal 1201. Since the radiation frequency of the vehicle-mounted antenna is generally high, the wavelength is short, and it is a horizontal omnidirectional antenna, the sheet metal 1201 is generally located more than 8 mm (greater than or equal to 1 / 4 wavelength) behind the antenna. In other words, after the antenna is projected to the same plane as the sheet metal 1201, the minimum distance between the antenna and the sheet metal 1201 must be greater than or equal to 1 / 4 wavelength. Such a distance can make the sheet metal 1201 have less impact on the radiation performance of the antenna.

[0084] The second type is that the antenna partially overlaps with the sheet metal 1201. The sheet metal 1201 is not directly below the antenna and partially overlaps with the antenna projection. It should be noted that if the antenna in the antenna glass is the antenna in Figure 2 or 3, the gap between the first radiator and the second radiator of the antenna cannot be blocked by the sheet metal 1201; if the antenna in the antenna glass is the antenna in Figure 4 or 5 or 9 or 10, the gap between the first radiator and the proximal radiator of the antenna and the gap between the proximal radiator and the distal radiator cannot be blocked by the sheet metal 1201.

[0085] The third type is that the antenna completely overlaps the sheet metal 1201. If the antenna projected onto the surface of the sheet metal 1201 is completely covered by the sheet metal 1201, the vertical distance between the sheet metal 1201 and the antenna is set to be greater than or equal to 16 mm (approximately 1 / 2 wavelength), so that the sheet metal 1201 can have less impact on the radiation performance of the antenna.

[0086] It should be noted that the wavelengths mentioned above refer to the actual radiation wavelengths of the antennas.

[0087] In summary, the present application combines the antenna with the window glass and sheet metal parts. The influence of the window glass on the antenna is considered in the design process, and the sheet metal parts are used as part of the antenna design, so as to obtain the positional relationship between the antenna and the window glass and sheet metal parts as described in the above antenna glass embodiment and vehicle embodiment. Moreover, since the current distribution of the antenna is mainly concentrated in the gap, the silver paste area is not the main radiation area, so when the silver paste area is close to the sheet metal part or the Low-E film layer, the impact will be smaller, and thus the antenna of the present application has strong anti-interference and high radiation efficiency.

[0088] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the present application. It should be noted that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
