Description

Technical Field

[0001] This application relates to the field of automotive window glass antenna technology, and in particular to automotive window glass. Background Technology

[0002] With the development of intelligent vehicle technology, many vehicle products can now realize remote door opening and other remote interaction functions. These remote interaction functions can be realized by installing an antenna on the vehicle. Users can communicate with the antenna through a mobile phone APP or car key, so that users can output corresponding interaction commands.

[0003] In related technologies, a common approach is to install the antenna module both internally and externally. In this approach, two antennas are installed alternately on the front bumper of the vehicle, and two antennas are installed alternately on the rear bumper of the vehicle.

[0004] However, the above-mentioned antenna module setup has the following problems: due to the electromagnetic shielding effect of the body sheet metal, the body sheet metal will electromagnetically shield the antenna radiation, which will seriously affect the antenna radiation performance and is not conducive to improving the antenna's interaction capability.

[0007] At least one glass body; the glass body has a light-transmitting portion and a shielding portion, the shielding portion being disposed around the light-transmitting portion; the glass body includes a glass substrate and a conductive layer; the conductive layer is disposed over the glass substrate; the conductive layer has a conductive portion and at least two insulating portions; the conductive portion is disposed around at least two of the insulating portions; and at least two of the insulating portions are disposed on the shielding portion;

[0008] An antenna assembly includes at least two antenna assemblies; the at least two antenna assemblies are spaced apart from the glass body, and the at least two antenna assemblies are connected to at least two insulating members one by one, such that the at least two antenna assemblies are disposed in the shielding portion.

[0010] And / or, the window glass further includes at least two insulating members, which are disposed in a one-to-one correspondence with the insulating portion, so that at least a portion of the antenna assembly is insulated from the conductive portion.

[0011] In one embodiment, at least two of the antenna assemblies are arranged opposite each other along the length of the window glass;

[0012] And / or, at least two of the antenna assemblies are arranged opposite each other along the width direction of the window glass.

[0014] In one embodiment, the glass body includes a first side and a second side disposed opposite to each other along the length direction of the window glass, and a third side and a fourth side disposed opposite to each other along the width direction of the window glass; the third side and the fourth side are both connected between the first side and the second side.

[0015] In one embodiment, at least one of the glass bodies includes a windshield glass; at least two of the antenna assemblies are spaced apart from the windshield glass;

[0016] And / or, at least one of the glass bodies includes a rear window glass; at least two of the antenna assemblies are spaced apart from the rear window glass.

[0017] In one embodiment, at least one of the glass bodies includes a left windshield window glass; at least two of the antenna assemblies are spaced apart from the left windshield window glass;

[0018] And / or, at least one of the glass bodies includes a right windshield glass, which is disposed on the vehicle body near the fourth side; at least two of the antenna assemblies are disposed at intervals on the right windshield glass.

[0019] In one embodiment, the glass body further includes a fifth side and a sixth side disposed opposite to each other along the height direction of the window glass, the fifth side being disposed away from the ground and the sixth side being disposed close to the ground, and at least two of the antenna assemblies being disposed close to the sixth side.

[0020] In one embodiment, the window glass further includes an adhesive layer, through which the antenna assembly is bonded to the insulating portion;

[0021] And / or, the vehicle window glass further includes a mounting component, the mounting component including a first body and a second body, the first body being connected and engaged with the glass body, the first body being connected to the second body, at least a portion of the second body being disposed opposite to the glass body along the thickness direction of the glass body, and the antenna assembly being mounted between the second body and the glass body, the second body being used to abut and engage with the antenna assembly.

[0024] The aforementioned vehicle window glass and vehicle employ an antenna assembly mounted on the glass assembly. This mounting method serves two purposes: firstly, it avoids excessive metal shielding of the antenna assembly by the vehicle's metal structure, ensuring the antenna assembly's radiation quality and thus improving antenna interaction performance; secondly, because the glass body is positioned close to the passenger compartment, the antenna assembly mounted on the glass assembly can radiate both outside the window glass and inside the passenger compartment, achieving a wide-range antenna radiation performance.

[0026] Furthermore, the cooperation between the insulating part and the antenna assembly ensures that the shielding part will not affect the radiation of the antenna assembly, thus guaranteeing the radiation range of the antenna assembly and ensuring the antenna interaction performance.

Detailed Implementation

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] See Figure 1 This application provides a vehicle 1, which includes a window glass 10 and a vehicle body 20. The window glass 10 includes at least one glass body 100 and an antenna assembly 200.

[0038] like Figures 2 to 3As shown, the glass body 100 is mounted on the vehicle body 20. The glass body 100 has a light-transmitting part 100a and a shielding part 100b, with the shielding part 100b surrounding the light-transmitting part 100a. The light-transmitting part 100a ensures good lighting inside the vehicle, while the shielding part 100b effectively blocks the light surrounding the light-transmitting part 100a. The shielding part 100b has stronger light absorption properties than the light-transmitting part 100a, thus reducing the heat load on the outer edge of the sunroof glass 110 and preventing it from cracking due to excessive heat. The shielding part 100b can be black or another dark color.

[0039] The glass body 100 includes a glass substrate 101 and a conductive layer 102. The conductive layer 102 covers the glass substrate 101. The conductive layer 102 has conductive portions and at least two insulating portions 102a. The conductive portions are wound around the at least two insulating portions 102a. The at least two insulating portions 102a are disposed on the shielding portion 100b. The conductive layer 102 can be formed by metal plating or by covering with a semiconductor layer (such as an ITO film), etc., without much limitation. In one example, the shielding portion 100b can be integrally formed with the conductive layer 102.

[0040] The antenna assembly 200 includes at least two antenna assemblies 200. The at least two antenna assemblies 200 are spaced apart from the glass body 100, and the at least two antenna assemblies 200 are connected to at least two insulating members, such that the at least two antenna assemblies 200 are disposed in the shielding portion 100b.

[0041] Understandably, by mounting the antenna assembly 200 on the glass body 100, on the one hand, the metal structure on the vehicle body 20 can avoid excessive metal shielding of the antenna assembly 200, ensuring the radiation quality of the antenna assembly 200 and thus improving antenna interaction performance; on the other hand, since the glass body 100 is located close to the vehicle compartment and is mounted on the vehicle body 20, the antenna assembly 200 mounted on the glass body 100 can radiate to both the outside of the window glass 10 and the inside of the vehicle compartment, achieving wide-range antenna radiation performance.

[0042] Furthermore, the shielding part 100b can be installed and fitted with the vehicle body 20, and the shielding part 100b will be at least partially covered during the actual installation and fitting process. By using the shielding part 100b as the installation area of ​​the antenna assembly 200, the antenna assembly 200 will not be too obvious when viewed from inside the vehicle or outside the window glass 10, reducing interference with the appearance of the window glass 10 and avoiding potential damage to the antenna assembly 200 due to exposure.

[0043] Furthermore, the cooperation between the insulating part 102a and the antenna assembly 200 ensures that the shielding part 100b will not cause radiation impact on the antenna assembly 200, thus guaranteeing the radiation range of the antenna assembly 200 and ensuring antenna interaction performance.

[0044] It is understood that, and it should be noted, the conductive layer 102 in the above embodiments can be formed on the glass substrate 101 by metal plating. Furthermore, the insulating portion 102a in the above embodiments can be formed by covering it with an insulating material. Alternatively, it can be formed by avoiding the presence of non-metallic areas during metal plating of the sunroof glass 110, thus making the non-metallic areas the insulating portion 102a.

[0045] Specifically, in one example, the conductive layer 102 has a cutout portion, which is used to form the insulating portion 102a. It is understood that when the conductive layer 102 is formed by metal plating, the insulating portion 102a area can be bypassed during the processing of the glass substrate 101, thus forming the cutout portion on the conductive layer 102. However, when the conductive layer 102 is formed by covering with a semiconductor film, the film can be removed directly at the corresponding position of the insulating portion 102a during the processing of the glass substrate 101 to form the cutout portion.

[0046] In another example, the window glass 10 also includes at least two insulating elements, which are disposed one-to-one with the insulating portion 102a, so that at least a portion of the antenna assembly 200 is insulated from the conductive portion. The insulating elements may be rubber pads, insulating cloth, etc., and the connection between the insulating elements and the glass substrate 101 may be by bonding or by coating.

[0047] It should be noted that the antenna assembly 200 can be of various antenna types, such as UWB and Bluetooth, and can be selected according to different interaction requirements. Furthermore, the antenna assembly 200 can be mounted on different glass bodies 100, allowing for adaptive selection based on different installation needs. In addition, the position of at least two antenna assemblies 200 can be diagonally positioned relative to the vehicle body 20 (parallel to the diagonal of the vehicle body 20), or parallel to the length direction X or width direction Y of the window glass 10. Optionally, the length direction X of the window glass 10 is parallel to the length direction X of the vehicle body 20, and the width direction Y of the window glass 10 is parallel to the width direction Y of the vehicle body 20.

[0048] In some implementation methods, see back Figure 1The line connecting at least two antenna components 200 is parallel to the length direction X or width direction Y of the glass body 100. In one example, at least two antenna components 200 are arranged opposite each other along the length direction X of the glass body 100. This arrangement of at least two antenna components 200 opposite each other along the length direction X allows for a more uniform distribution of the radiation range of the antenna components 200 in the length direction X, thereby improving the radiation quality of the antenna.

[0049] In another example, at least two antenna components 200 are arranged opposite each other along the width direction Y of the glass body 100. Similarly, by arranging at least two antenna components 200 opposite each other along the width direction Y, the radiation range of the antenna components 200 in the width direction Y can be more uniformly distributed, thereby improving the radiation quality of the antenna.

[0050] In any embodiment of the glass body 100 described above, as shown in FIG. 4, at least one glass body 100 includes a sunroof glass 110. Optionally, the sunroof glass 110 is disposed on the vehicle body 20. The sunroof glass 110 is provided with a light-transmitting portion 100a and a shielding portion 100b. At least two antenna assemblies 200 are spaced apart from each other on the shielding portion 100b.

[0051] The distribution of at least two antenna components 200 in the sunroof glass 110 can be random or placed at any position such as the corner of the sunroof glass 110, without much limitation.

[0052] In any of the embodiments of the vehicle body 20 described above, the length direction X and width direction Y of the vehicle body 20 are consistent with the length direction X and width direction Y of the window glass 10. Specifically, see [link to previous section]. Figure 1 The vehicle body 20 includes a first side 200a and a second side 200b disposed opposite each other along the length direction X of the vehicle body 20, and a third side 200c and a fourth side 200d disposed opposite each other along the width direction Y of the vehicle body 20. The third side 200c and the fourth side 200d are both connected between the first side 200a and the second side 200b.

[0053] Furthermore, see you again Figure 4 The sunroof glass 110 has a seventh side 111 and an eighth side 112 opposite each other along the length direction X, and a ninth side 113 and a tenth side 114 opposite each other along the width direction Y. The seventh side 111 is located near the first side 200a, the eighth side 112 is located near the second side 200b, the ninth side 113 is located near the third side 200c, and the tenth side 114 is located near the fourth side 200d. The ninth side 113 and the tenth side 114 are both connected between the seventh side 111 and the eighth side 112.

[0054] In one example, at least one antenna assembly 200 is positioned near the connection between the seventh side 111 and the ninth side 113. At least one antenna assembly 200 is positioned near the connection between the seventh side 111 and the tenth side 114. In this case, the at least two antenna assemblies 200 can be positioned opposite each other or not opposite each other; no particular restrictions are placed here. Thus, the at least two antenna assemblies 200 are positioned near the first side 200a and distributed at two corners of the first side 200a, resulting in good radiation performance in front of the vehicle window 10, meeting the requirements for front antenna interaction performance.

[0055] In another example, at least one antenna assembly 200 is positioned near the connection between the eighth side 112 and the ninth side 113. At least one antenna assembly 200 is positioned near the connection between the eighth side 112 and the tenth side 114. In this case, the at least two antenna assemblies 200 can be positioned opposite each other or not opposite each other; no particular restrictions are placed here. Thus, the at least two antenna assemblies 200 are positioned near the second side 200b and distributed at two corners of the second side 200b, resulting in good radiation performance behind the vehicle window glass 10, meeting the requirements for rear antenna interaction performance.

[0056] In some embodiments, see back Figure 4 The antenna assembly 200 may include at least four antenna assemblies 200. The at least four antenna assemblies 200 include a first antenna 210, a second antenna 220, a third antenna 230, and a fourth antenna 240. The first antenna 210, the second antenna 220, the third antenna 230, and the fourth antenna 240 are respectively positioned near the four corners of the sunroof glass 110, so that the radiation range of the antenna assembly 200 can cover the window glass 10 and its surrounding area to the greatest extent possible, which is beneficial to improving the interactive performance of the antenna assembly 200.

[0057] In some embodiments, as shown in FIG. 5, the window glass 10 further includes a sunshade assembly 300, which is spaced apart from the sunroof glass 110 along the thickness direction Z of the window glass 10. Specifically, in one example, the sunshade assembly 300 has a rolled-up state and a released state. When the sunshade assembly 300 is in the rolled-up state, it is separated from the light-transmitting portion 100a. When the sunshade assembly 300 is in the released state, it covers at least a portion of the light-transmitting portion 100a and is spaced apart from the first antenna 210, the second antenna 220, the third antenna 230, and the fourth antenna 240.

[0058] Understandably, when the sunshade assembly 300 is in the retracted state, it does not interfere with the normal function of the light-transmitting part 100a, ensuring sufficient light inside the vehicle. When the sunshade assembly 300 is in the deployed state, it effectively blocks at least part of the light-transmitting part 100a, providing passengers with a more private and comfortable riding environment. Furthermore, the spacing between the sunshade assembly 300 and the antenna assembly 200 prevents the antenna assembly 200 from interfering with the unfolding and retraction of the sunshade, ensuring the performance of the sunshade assembly 300.

[0059] Furthermore, in one example, when the sunshade assembly 300 is in the released state, the shortest distance along the thickness direction Z between the sunshade assembly 300 and any one of the first antenna 210, the second antenna 220, the third antenna 230 and the fourth antenna 240 is P, where P ≥ 8 mm.

[0060] Thus, the shortest distance between the sunshade assembly 300 and the antenna assembly 200 along the thickness direction Z needs to exceed 8mm, which can ensure that the antenna assembly 200 will not obstruct or interfere with the opening and closing of the sunshade assembly 300, thus ensuring the normal opening and closing of the sunshade assembly 300.

[0061] In other implementations, see back Figure 1 At least one of the glass bodies 100 includes a windshield 120. Optionally, the windshield 120 is disposed on the vehicle body 20 near the first side 200a. At least two antenna assemblies 200 are spaced apart from each other on the windshield 120. Thus, the placement of at least two antenna assemblies 200 on the windshield 120 helps to enhance the signal reception and transmission capabilities in front of the windshield 10.

[0062] It should be noted that when at least two antenna assemblies 200 are mounted on the windshield 120, they can be mounted in any position, such as in a corner of the windshield 120 or near the outer sidewall of the windshield 120.

[0063] In another embodiment, at least one glass body 100 includes a rear window glass 130. Optionally, the rear window glass 130 is disposed on the vehicle body 20 near the second side 200b. At least two antenna assemblies 200 are spaced apart from each other on the rear window glass 130. Similarly, the at least two antenna assemblies 200 disposed on the rear window glass 130 help to enhance the signal reception and transmission capabilities behind the window glass 10, and also improve the signal coverage capabilities behind the window glass 10.

[0064] In one embodiment, see back Figure 1At least one glass body 100 includes a left windshield window 140. Optionally, the left windshield window 140 is disposed on the vehicle body 20 near the third side 200c. At least two antenna assemblies 200 are spaced apart from each other on the left windshield window 140. Thus, the at least two antenna assemblies 200 disposed on the left windshield window 140 help to enhance the signal reception and transmission capabilities on the left side of the window 10.

[0065] In another embodiment, at least one glass body 100 includes a right-side windshield 150. Optionally, the right-side windshield 150 is disposed on the vehicle body 20 near the fourth side 200d. At least two antenna assemblies 200 are spaced apart from each other on the right-side windshield 150. Thus, the placement of at least two antenna assemblies 200 on the right-side windshield 150 helps to enhance the signal reception and transmission capabilities on the right side of the windshield 10.

[0066] Furthermore, in one example, at least two antenna assemblies 200 include a first antenna 210 and a second antenna 220. The first antenna 210 may be positioned close to the vehicle body 20 on the A-pillar of the third side 200c (the first antenna 210 may be positioned on the side of the windshield 120 close to the third side 200c, or the first antenna 210 may be positioned on the side of the left windshield 140 close to the first side 200a).

[0067] The second antenna 220 can be positioned near the A-pillar on the fourth side 200d of the vehicle body 20 (the second antenna 220 can be positioned on the side of the windshield 120 near the fourth side 200d, or the second antenna 220 can be positioned on the side of the right windshield 150 near the first side 200a). Thus, having at least two antenna assemblies 200 positioned near the A-pillars on both sides helps to increase the radiation range of the antenna assembly 200 in the width direction Y, thereby enhancing the signal reception and transmission capabilities in front of the windshield 10.

[0068] In another example, at least two antenna assemblies 200 include a third antenna 230 and a fourth antenna 240. The third antenna 230 may be positioned near the C-pillar on the third side 200c of the vehicle body 20. Optionally, the third antenna 230 may be positioned on the side of the rear windshield 130 near the third side 200c, or the third antenna 230 may be positioned on the side of the left windshield 140 near the second side 200b.

[0069] The fourth antenna 240 can be positioned near the C-pillar on the fourth side 200d of the vehicle body 20. Specifically, the fourth antenna 240 can be positioned on the side of the rear windshield 130 near the fourth side 200d, or it can be positioned on the right windshield 150 near the second side 200b. This arrangement of at least two antenna assemblies 200 near the C-pillars on both sides helps to increase the radiation range of the antenna assemblies 200 in the width direction Y, thereby enhancing the signal reception and transmission capabilities in front of the windshield 10.

[0070] Furthermore, in other embodiments, see back Figure 1 The glass body 100 also includes a fifth side and a sixth side disposed opposite to each other along the height direction of the window glass 10. The fifth side is disposed away from the ground, and the sixth side is disposed close to the ground. At least two antenna assemblies 200 are disposed close to the sixth side. In one example, when at least two antenna assemblies 200 are disposed on the windshield 120, at least two antenna assemblies 200 are disposed on the side of the windshield 120 closest to the sixth side. In another example, when at least two antenna assemblies 200 are disposed on the rear windshield 130, at least two antenna assemblies 200 are disposed on the side of the rear windshield 130 closest to the sixth side. Similarly, at least two antenna assemblies 200 can also be disposed on the side of the left windshield 140 or right windshield 150 closest to the sixth side. Optionally, the height direction of the window glass 10 is parallel to the height direction of the vehicle body 20.

[0071] Thus, by positioning the antenna assembly 200 on the sixth side, close to the ground, the impact of the antenna assembly 200 on the appearance of the window glass 10 is effectively reduced. Furthermore, by positioning the antenna assembly 200 on the second side 200b, near the bottom of the window glass 10, i.e., close to the ground, the radiation range of the antenna assembly 200 can be more concentrated at the same height as the window glass 10, thereby improving the quality of antenna interaction scenarios such as UWB key unlocking.

[0072] In conjunction with any embodiment of the glass body 100 described above, such as Figure 6 As shown, Figure 3 As shown, the window glass 10 also includes an adhesive layer 400, through which the antenna assembly 200 is bonded to the sunroof glass 110.

[0073] Thus, the adhesive layer 400 allows the antenna assembly 200 to be securely mounted on the glass body 100, improving the installation reliability and stability of the antenna assembly 200. Furthermore, the adhesive layer 400, typically made of a flexible material, also provides a buffer between the glass body 100 and the antenna assembly 200, preventing damage from impacts. In addition, the adhesive layer 400 simplifies the installation process of the antenna assembly 200, eliminating the need for processing the glass body 100, reducing the processing cost of the vehicle window glass 10, and improving production efficiency.

[0074] In addition, in one example, the adhesive layer 400 can be integrally formed with the insulating layer in the above embodiment, which helps to reduce the space occupied by the window glass 10 in the thickness direction Z.

[0075] Furthermore, in one embodiment, such as Figure 6 As shown, the vehicle window glass 10 also includes a mounting component 500, which includes a first body 510 and a second body 520. The first body 510 is connected and engaged with the glass body 100, and the first body 510 is connected to the second body 520. At least a portion of the second body 520 and the glass body 100 are arranged opposite each other along the thickness direction Z of the glass body 100, and the antenna assembly 200 is installed between the second body 520 and the glass body 100. The second body 520 is used to abut and engage with the antenna assembly 200.

[0076] It should be noted that the second body 520 and the antenna assembly 200 can be in close contact or spaced apart. In this case, the second body 520 can provide support for the antenna assembly 200 to prevent the antenna assembly 200 from falling directly.

[0077] Thus, the antenna assembly 200 is installed between the second body 520 and the glass body 100. This design not only simplifies the positioning process during installation but also improves the installation stability and reliability of the antenna assembly 200. Furthermore, the mating fit between the second body 520 and the antenna assembly 200 further ensures the robustness of the antenna assembly 200. Even if the antenna assembly 200 becomes loose due to vibrations during vehicle operation, the second body 520 can provide good support, protecting the antenna assembly 200 from damage.

[0078] In other implementations, see back Figure 4 The vehicle body 20 is provided with a sheet metal part 201, which is used to install the glass body 100 and is arranged around the glass body 100. The distance between the outer side wall of the antenna assembly 200 and the inner side wall of the sheet metal part 201 is H, where H ≥ 3mm.

[0079] Thus, by setting the antenna assembly 200 and the sheet metal part 201 at intervals with H≥3mm, an appropriate gap is maintained between the antenna assembly 200 and the sheet metal part 201, thereby reducing electromagnetic interference and ensuring antenna interaction quality.

[0080] Optionally, H ≥ 5mm. In this way, H ≥ 5mm can widen the distance between the antenna assembly 200 and the sheet metal part 201, further reducing electromagnetic interference and improving antenna interaction quality.

[0081] Optional, see Figure 1 as well as Figure 4 The antenna assembly 200 may include four antenna assemblies 200. The four antenna assemblies 200 may be installed on the vehicle body 20 in the following ways.

[0082] In one embodiment, four antenna assemblies 200 are installed at the four corners of the sunroof glass 110. For ease of explanation later, the installation scheme in this embodiment will be referred to as the front and rear blind assembly.

[0083] In another embodiment, two antenna assemblies 200 are mounted at two corners of the front windshield 120 near the sixth side. Two antenna assemblies 200 are also mounted at two corners of the rear windshield 130 near the sixth side. For ease of explanation later, this mounting configuration is referred to here as the front and rear windshield lower assembly.

[0084] In other embodiments, an antenna assembly 200 is positioned near the left windshield 140 on the side near the first side 200a (i.e., the antenna assembly 200 is positioned near the A-pillar of the vehicle body 20 on the left windshield 140). An antenna assembly 200 is positioned near the left windshield 140 on the side near the second side 200b (i.e., the antenna assembly 200 is positioned near the C-pillar of the vehicle body 20 on the left windshield 140). An antenna assembly 200 is positioned near the right windshield 150 on the side near the first side 200a (i.e., the antenna assembly 200 is positioned near the A-pillar of the vehicle body 20 on the right windshield 150). An antenna assembly 200 is positioned near the right windshield 150 on the side near the second side 200b (i.e., the antenna assembly 200 is positioned near the C-pillar of the vehicle body 20 on the right windshield 150). For ease of explanation later, the installation scheme in this embodiment is referred to here as a front and rear triangular assembly.

[0085] like Figure 7As shown, this application performs the following tests on the front and rear triangle group, front and rear lower bumper group, front and rear upper bumper group, and common scheme group in the above embodiments. The common scheme group refers to a configuration where two antenna assemblies 200 are installed on the front bumper of the vehicle body 20, two antenna assemblies 200 are installed on the rear bumper of the vehicle body 20, and the antenna assemblies 200 are not correspondingly positioned with the insulating part 102a.

[0086] In one test scenario, the test vehicle window was placed in an open environment of approximately 15m x 15m, and data was collected for 20 seconds at each sampling point (average value was taken); and the antenna performance was tested at three distances (2 meters, 5 meters, and 10 meters) in eight directions (with the test vehicle window as the center, referring to the eight directions formed by the star shape).

[0087] Finally, for each installation group, approximately 20 sets of data were collected at each point, resulting in a total of 9,500 sets of data to verify the number of defective data.

[0088] from Figure 7 It can be seen that the number of defective data for the antenna on the windshield 10 of this application is significantly reduced compared to common solutions in related technologies, thus demonstrating that the antenna radiation performance on the windshield 10 of this application is excellent. Furthermore, in specific test scenarios, it can be found that the front and rear windshield groups (i.e., the antenna assembly 200 is installed on the sunroof glass 110) exhibit the fewest defective data and the best antenna radiation performance.

[0089] Based on this, it can be considered that the antenna assembly 200 and the insulating part 102a are correspondingly arranged in the above-mentioned window glass 10, and the four antenna assemblies 200 are arranged in the manner of the embodiment, which is beneficial to reduce the number of undesirable antenna interaction parameters, that is, it can improve the radiation performance of the antenna assembly 200 in the window glass 10.

[0090] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
