Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to a vehicle-mounted antenna assembly and a vehicle-mounted antenna device. Background Technology

[0002] With the rapid development of wireless communication and in-vehicle equipment, the performance requirements for in-vehicle communication equipment are also increasing. Because in-vehicle communication equipment needs to support multi-mode, multi-band communication networks, such as Sub-6GHz bands (e.g., 3.3GHz to 4.9GHz) and 5.9GHz (5.905 to 5.925GHz) Vehicle to Everything (V2X) bands, the number of in-vehicle receiving antennas and the number of frequency bands supported by in-vehicle communication equipment are increasing.

[0003] Existing in-vehicle communication equipment typically employs a shark fin antenna structure to integrate powerful automotive electronic functions such as Frequency Modulation (FM), Global Positioning System (GPS), and Global System for Mobile Communications (GSM), as well as all the functions of various antennas. However, because shark fin antennas need to be mounted on the vehicle roof, vehicles equipped with panoramic sunroofs or vehicles with height restrictions cannot be equipped with them. Therefore, shark fin antennas no longer meet the complex installation requirements of the market.

[0004] In summary, how to provide a vehicle-mounted antenna assembly that can effectively reduce its size and save installation space to meet the complex installation requirements of the market, based on the urgent need for multifunctionality, high integration, and miniaturization, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] This application provides a vehicle-mounted antenna assembly and a vehicle-mounted antenna device, which can solve the problem that existing vehicle-mounted communication devices, due to their shark fin antenna structure, cannot meet market demands.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] This application provides a vehicle-mounted antenna assembly, comprising: a substrate, at least two sets of mobile communication antenna element groups, a positioning antenna module, and a vehicle networking antenna module. The substrate has openings at both ends; the at least two sets of mobile communication antenna element groups are respectively disposed at both ends of the substrate, each set including at least two mobile communication antenna elements, with the at least two elements respectively disposed on opposite sides of the corresponding opening; the positioning antenna module is disposed on the substrate and positioned between the two ends of the substrate; the vehicle networking antenna module is disposed on the substrate and positioned next to the positioning antenna module.

[0008] This application provides a vehicle-mounted antenna device, comprising: a vehicle-mounted antenna assembly and a mounting base according to embodiments of this application. A substrate is disposed on the mounting base, and at least two sets of mobile communication antenna elements are coupled to corresponding portions of the mounting base to adjust the resonant frequency.

[0009] In this embodiment, by spatially arranging at least two sets of mobile communication antenna elements, a positioning antenna module, and a vehicle-to-everything (V2X) antenna module, the vehicle-mounted antenna assembly achieves multifunctionality, high integration, and miniaturization while possessing positioning, V2X, and mobile communication functions. This effectively reduces size and saves installation space to meet complex installation requirements. Furthermore, by positioning at least two sets of mobile communication antenna elements at opposite ends of the substrate, and by using air dielectric isolation between at least two antenna elements in each set, the vehicle-mounted antenna assembly and device can solve the problem of poor isolation between mobile communication antennas in a vehicle-mounted mobile communication system. Moreover, by coupling the mounting base with at least two sets of mobile communication antenna elements, the vehicle-mounted antenna device can improve the resonant parameters of the at least two sets of mobile communication antenna elements, thereby increasing the frequency bandwidth of the at least two sets of mobile communication antenna elements.

[0027] The embodiments of the present invention will be described below with reference to the accompanying drawings. In these drawings, the same reference numerals denote the same or similar components or method flows.

[0028] Please see Figure 1 and Figure 2 , Figure 1 This is a perspective view of an embodiment of the vehicle-mounted antenna assembly according to this application. Figure 2 for Figure 1 A top-view diagram of the vehicle-mounted antenna assembly. (See diagram below.) Figure 1 and Figure 2 As shown, the vehicle-mounted antenna assembly 100 includes: a substrate 110, at least two sets of mobile communication antenna elements (i.e., mobile communication antenna elements 120a and 120b), a positioning antenna module 130, and a vehicle networking antenna module 140. The substrate 110 has openings at both ends (i.e., openings 50a and 50b are respectively provided at the left and right ends of the substrate 110); at least two sets of mobile communication antenna elements are respectively disposed at both ends of the substrate 110 (i.e., mobile communication antenna elements 120a and 120b are respectively disposed at the left and right ends of the substrate 110). In one embodiment, the mobile communication antenna elements may be, but are not limited to, printed on the substrate 110. In this embodiment, the number of mobile communication antenna elements may be two (i.e., mobile communication antenna elements 120a and 120b), but this embodiment is not intended to limit the application and can be adjusted according to actual needs.

[0029] Each group of mobile communication antenna elements includes at least two mobile communication antenna elements (i.e., mobile communication antenna element group 120a includes mobile communication antenna element 60a and mobile communication antenna element 60b, and mobile communication antenna element group 120b includes mobile communication antenna element 60c and mobile communication antenna element 60d). In each group of mobile communication antenna elements, at least two mobile communication antenna elements are respectively disposed on both sides of the corresponding opening slot (i.e., mobile communication antenna element 60a and mobile communication antenna element 60b are respectively disposed in opening slot 50a). On both sides, mobile communication antenna elements 60c and 60d are respectively disposed on both sides of the opening slot 50b; that is, mobile communication antenna elements 60a and 60b are isolated by air medium, and mobile communication antenna elements 60c and 60d are isolated by air medium. The positioning antenna module 130 is disposed on the substrate 110 and positioned between the two ends of the substrate 110. The vehicle networking antenna module 140 is disposed on the substrate 110 and positioned next to the positioning antenna module 130.

[0030] Therefore, the vehicle-mounted antenna assembly 100 provided in this embodiment includes at least two sets of mobile communication antenna elements, a positioning antenna module 130, and a vehicle networking antenna module 140 to form a multifunctional combined antenna structure, and effectively reduces its volume through lightweight spatial arrangement. Furthermore, to improve the isolation between the at least two sets of mobile communication antenna elements, mobile communication antenna elements 120a and 120b are respectively disposed at both ends of the substrate 110; to improve the isolation between mobile communication antenna elements 60a and 60b, and between mobile communication antenna elements 60c and 60d, air dielectric isolation is used between mobile communication antenna elements 60a and 60b, and between mobile communication antenna elements 60c and 60d, thus solving the problem of poor isolation between mobile communication antennas in the vehicle-mounted mobile communication system. Furthermore, by printing the mobile communication antenna elements 60a, 60b, 60c, and 60d onto the same substrate, space utilization is improved, production is simplified, and the need to solder the antennas is avoided, which could lead to errors and inconsistent antenna impedance and performance.

[0031] In actual implementation, the substrate 110 may be, but is not limited to, a printed circuit board (PCB), and the mobile communication antenna vibrator 60a, mobile communication antenna vibrator 60b, mobile communication antenna vibrator 60c and mobile communication antenna vibrator 60d may be, but are not limited to, PCB antennas.

[0032] In one practical example, the material of substrate 110 may include, but is not limited to, ceramic materials, FR-4 epoxy resin, polystyrene, polypropylene, polyimide, polyethylene, polyetheretherketone, polytetrafluoroethylene, or mixtures thereof.

[0033] In one practical example, the opening slots 50a and 50b can be disposed on the central axis (not shown) of the long side of the substrate 110, such that the mobile communication antenna vibrator 60a and 60b are symmetrically distributed about the central axis, and the mobile communication antenna vibrator 60c and 60d are symmetrically distributed about the central axis.

[0034] In one practical example, there are two opening slots (i.e., opening slot 50a and opening slot 50b), which extend from the edge openings at both ends of the substrate 110 along the width direction P parallel to the substrate 110 and have an opening depth U. Each opening depth U corresponds to the width W of the adjacent mobile communication antenna element in the width direction P parallel to the substrate 110. In one example, each opening depth U may be greater than or approximately equal to the width W of the adjacent mobile communication antenna element in the width direction P parallel to the substrate 110.

[0035] In one practical example, the mobile communication antenna vibrator group 120a and the mobile communication antenna vibrator group 120b are designed to be mirror-symmetrical.

[0036] In a practical example, please refer to Figure 3 This is a schematic diagram of a circuit architecture of at least two sets of mobile communication antenna elements and a first matching circuit unit according to this application. Figure 3 As shown, the vehicle-mounted antenna assembly 100 may further include a first matching circuit unit 150, connected to the mobile communication antenna vibrator group 120a and the mobile communication antenna vibrator group 120b, for adjusting the impedance of the mobile communication antenna vibrator group 120a and the mobile communication antenna vibrator group 120b. In one embodiment, the first matching circuit unit 150 may include four sub-matching circuits (i.e., sub-matching circuit 150a, sub-matching circuit 150b, sub-matching circuit 150c, and sub-matching circuit 150d), for matching the mobile communication antenna vibrator 60a, mobile communication antenna vibrator 60b, mobile communication antenna vibrator 60c, and mobile communication antenna vibrator 60d respectively. Therefore, through the configuration of the first matching circuit unit 150, the maximum power transmission of radio signals in the mobile communication system can be achieved. The circuit design and placement of the first matching circuit unit 150 can be adjusted according to actual needs. In one embodiment, the first matching circuit unit 150 is disposed on the substrate 110.

[0037] In one practical example, mobile communication antenna elements 60a, 60b, 60c, and 60d may be, but are not limited to, fifth-generation (5G) antenna elements, and each group of said mobile communication antenna elements is a 5G mobile communication antenna element group. In one embodiment, the 5G antenna elements may be, but are not limited to, multiple input multiple output (MIMO) antenna elements; the antenna frequency bands of mobile communication antenna elements 60a, 60b, 60c, and 60d may be, but are not limited to, sub-6GHz frequency bands (e.g., 3.3GHz to 3.6GHz and 4.8GHz to 5.0GHz), and all are backward compatible with 2G / 3G / 4G frequency bands (e.g., 690MHz to 960MHz, 1.71GHz to 2.17GHz, and 2.3GHz to 2.69GHz).

[0038] In a practical example, please refer to Figure 4 , its purpose is Figure 1 A schematic diagram of the circuit architecture of an embodiment of the positioning antenna module. (See diagram below.) Figure 4 As shown, the positioning antenna module 130 may include: a positioning antenna element 132, an amplifier circuit unit 134, and a third matching circuit unit 136. The positioning antenna element 132 is connected to the amplifier circuit unit 134, and the amplifier circuit unit 134 is connected to the third matching circuit unit 136. The positioning antenna element 132 is used to receive satellite positioning signals; the amplifier circuit unit 134 is used to receive and amplify the satellite positioning signals to output a position signal; and the third matching circuit unit 136 is used for impedance matching. The positioning antenna module 130 outputs a position signal to the control system of the vehicle equipped with the vehicle-mounted antenna assembly 100, enabling the control system to analyze and process the output position signal to obtain the vehicle's position coordinates.

[0039] In one practical example, the positioning antenna element 132 can be, but is not limited to, a ceramic antenna.

[0040] In one practical example, the positioning antenna module 130 may be, but is not limited to, a GPS antenna, a BeiDou Navigation Satellite System (BeiDou) antenna, a Galileo Positioning System (Galileo) antenna, or a Global Navigation Satellite System (GNSS) antenna. The GPS antenna has frequency bands including L1 (1575.42MHz) and L2 (1227.60MHz), the Galileo antenna has frequency bands including E1 (1589.74MHz), E2 (1561.1MHz), E5a (1176.45MHz), E5b (1207.14MHz) or E6 (1278.75MHz), the Beidou antenna has frequency bands including B1I (1561.098MHz) and B2I (1207.140MHz), and the GLONASS antenna has frequency bands including 1602+0.5625a (MHz) or 1246+0.4375a (MHz) (where a is the GLONASS satellite number).

[0041] In one practical example, the positioning antenna module 130 may be disposed on the central axis (not shown) of the long side of the substrate 110.

[0042] In a practical example, please refer to Figure 5 , it is Figure 1 A schematic diagram of the circuit architecture of an embodiment of a vehicle-to-everything (V2X) antenna module. Figure 5 As shown, the vehicle-to-everything (V2X) antenna module 140 may include a V2X antenna element 142 and a second matching circuit unit 144, with the V2X antenna element 142 connected to the second matching circuit unit 144. The V2X antenna element 142 is used to receive signals; the second matching circuit unit 144 is used to adjust the impedance of the V2X antenna element 142. Through the configuration of the second matching circuit unit 144, maximum power transmission of radio signals in the V2X communication system is achieved. The circuit design and placement of the second matching circuit unit 144 can be adjusted according to actual needs. In one embodiment, the second matching circuit unit 144 is disposed on the substrate 110.

[0043] In a practical example, please refer to Figure 2The vehicle-to-everything (V2X) antenna module 140 may include a V2X antenna element 142. The distance D between the position of the V2X antenna element 142 on the substrate 110 and the edge of the substrate 110 is greater than 20 mm. This distance D improves manufacturing safety. Furthermore, when the vehicle-mounted antenna assembly 100 is housed within a housing, the distance D prevents the housing from affecting the resonant frequency shift of the V2X antenna element 142.

[0044] In a practical example, please refer to Figure 6 This is a top view schematic diagram of another embodiment of the vehicle-mounted antenna assembly according to this application. Figure 6 As shown, the vehicle-to-everything (V2X) antenna module 140 may include multiple V2X antenna elements 142, which are respectively configured on different sides of the positioning antenna module 130 to adjust the directivity of the V2X antenna module 140.

[0045] In a practical example, please refer to Figure 6 The vehicle-to-everything (V2X) antenna module 140 may include two V2X antenna elements 142, with a positioning antenna module 130 disposed between the two V2X antenna elements 142. The design of the positioning antenna module 130 disposed between the two V2X antenna elements 142 improves the isolation between them. In one embodiment, the V2X antenna module 140 may be, but is not limited to, a vehicle-to-everything (V2X) antenna module, and the V2X antenna elements 142 may be, but are not limited to, V2X antenna elements suitable for the V2X frequency band.

[0046] Please see Figures 7 to 10 , Figure 7 This is a perspective view of an embodiment of the vehicle-mounted antenna device according to this application. Figure 8 for Figure 7 A schematic diagram of the vehicle-mounted antenna assembly. Figure 9 for Figure 8 A top-view diagram of the vehicle-mounted antenna device. Figure 10 for Figure 9 A cross-sectional view along line segment AA. (See figure) Figures 7 to 10As shown, the vehicle-mounted antenna device 200 includes a vehicle-mounted antenna assembly 100 and a mounting base 210. A substrate 110 is disposed on the mounting base 210. Mobile communication antenna elements 120a and 120b are coupled to corresponding portions of the mounting base 210 to adjust their resonant frequencies. By coupling the mobile communication antenna elements 120a and 120b to corresponding portions of the mounting base 210, new resonant points can be added to the mobile communication antenna elements 120a and 120b, thereby increasing the antenna frequency bandwidth of the vehicle-mounted antenna device 200 in the mobile communication system. Furthermore, due to radiation, the bandwidth at the harmonics also increases, improving the antenna resonant parameters of the vehicle-mounted antenna device 200 in the mobile communication system.

[0047] In one example, the substrate 110 is fixed to the mounting base 210 by locking. In another example, the substrate 110 is fixed to the mounting base 210 by adhesive. It should be noted that, to avoid... Figure 7 The drawing is too complex and does not show the components / elements (e.g., screws or adhesive) that set the substrate 110 on the mounting base 210.

[0048] In one practical example, the dielectric constant of the material of the mounting base 210 is 2.2 to 2.6.

[0049] In one practical example, the material of the mounting base 210 may be, but is not limited to, polypropylene (PP), polyethylene (PE), polyamide, or mixtures thereof.

[0050] In one practical example, the vehicle-mounted antenna device 200 may further include a housing 220 for assembly with the mounting base 210 to form an internal space for housing the vehicle-mounted antenna assembly 100. The housing 220 may be made of materials including, but not limited to, polycarbonate and polyacrylonitrile (ABS). In one example, the housing 220 and the mounting base 210 may be assembled by a snap-fit ​​method to facilitate subsequent maintenance of the vehicle-mounted antenna device 200; in another example, the housing 220 and the mounting base 210 may be assembled by an adhesive method to prevent moisture from entering the internal space; the actual assembly method of the housing 220 and the mounting base 210 may be adjusted according to actual needs.

[0051] In one practical example, the mounting base 210 includes at least two platforms (i.e., platforms 212a and 212b) and a recess 214. The at least two platforms are located on both sides of the recess 214 (i.e., platforms 212a and 212b are located on both sides of the recess 214). The at least two platforms are close to the substrate 110 relative to the recess 214. At least two sets of mobile communication antenna elements are arranged corresponding to the at least two platforms (i.e., mobile communication antenna element group 120a is arranged corresponding to platform 212a, and mobile communication antenna element group 120b is arranged corresponding to platform 212b). (Setting 2b) Each group of mobile communication antenna elements is coupled to the platform corresponding to its position (i.e., mobile communication antenna element group 120a is coupled to platform 212a, and mobile communication antenna element group 120b is coupled to platform 212b). The distance between each group of mobile communication antenna elements and the platform corresponding to its position is less than 5 mm (i.e., the distance between mobile communication antenna element group 120a and platform 212a is less than 5 mm, and the distance between mobile communication antenna element group 120b and platform 212b is less than 5 mm). Figure 11 As shown, Figure 11 for Figure 10 An enlarged schematic diagram of block B is shown. In this embodiment, the number of platforms can be two sets (i.e., platform 212a and platform 212b), but this embodiment is not intended to limit this application and can be adjusted according to actual needs. It should be noted that the mobile communication antenna vibrator group corresponds one-to-one with the platform, but the number of mobile communication antenna vibrator groups and platforms may not be the same.

[0052] In a practical example, please refer to Figure 6 and Figure 7 Each opening depth U is greater than the width F of the platform corresponding to the adjacent mobile communication antenna vibrator in the width direction P of the parallel substrate 110.

[0053] In a practical example, please refer to Figure 7 and Figure 12 , Figure 12 for Figure 7 A three-dimensional diagram of the mounting base. (See diagram below.) Figure 7 and Figure 12 As shown, the opening of the groove 214 faces the substrate 110. The sidewall of the groove 214 has multiple openings 80. The vehicle-mounted antenna device 200 also includes multiple transmission lines (not shown). These transmission lines are connected to the output ports of the mobile communication antenna vibrator group 120a, mobile communication antenna vibrator group 120b, positioning antenna module 130, and vehicle networking antenna module 140 via the multiple openings 80 and the groove 214. The transmission lines can be, but are not limited to, coaxial cables. It should be noted that, to avoid… Figure 7 The diagram is too complex and the multiple transmission lines are not shown.

[0054] In one practical example, since the mobile communication antenna vibrator group 120a includes mobile communication antenna vibrator 60a and mobile communication antenna vibrator 60b, the mobile communication antenna vibrator group 120b includes mobile communication antenna vibrator 60c and mobile communication antenna vibrator 60d, the positioning antenna module 130 includes positioning antenna vibrator 132, and the vehicle networking antenna module 140 includes vehicle networking antenna vibrator 142, the number of openings 80 can be 6, and the number of transmission lines can be 6 (the 6 transmission lines are respectively connected to the output ports corresponding to the mobile communication antenna vibrator 60a, mobile communication antenna vibrator 60b, mobile communication antenna vibrator 60c, mobile communication antenna vibrator 60d, positioning antenna vibrator 132 and vehicle networking antenna vibrator 142).

[0055] In one example, the groove 214 is provided with a plurality of support portions 90 for locking with the substrate 110, and the substrate 110 is provided with a plurality of through holes 92; when the substrate 110 is placed on the mounting base 210, the support portions 90 and the through holes 92 correspond one-to-one, and the substrate 110 is fixed to the mounting base 210 by a locking element (e.g., screw).

[0056] In a practical example, please refer to Figure 9 and Figure 12 The mounting base 210 may also include multiple mounting portions 216 for securing the vehicle-mounted antenna device 200 to the vehicle. The vehicle-mounted antenna device 200 can be secured to the vehicle by passing multiple locking elements (e.g., screws) through multiple mounting holes 30 of the multiple mounting portions 216.

[0057] In summary, this embodiment of the application, through the spatial arrangement of two sets of mobile communication antenna elements, a positioning antenna module, and a vehicle-to-everything (V2X) antenna module, achieves the multi-functionality, high integration, and miniaturization requirements of the vehicle-mounted antenna assembly while possessing positioning, V2X, and mobile communication functions. This effectively reduces volume and saves installation space to meet complex installation requirements. Furthermore, by printing the two sets of mobile communication antenna elements on both ends of the substrate, and by using air dielectric isolation between adjacent mobile communication antenna elements within each set, the vehicle-mounted antenna assembly and device can solve the problem of poor isolation between mobile communication antennas in a vehicle-mounted mobile communication system. In addition, through the design of coupling the mounting base and the two sets of mobile communication antenna elements, the vehicle-mounted antenna device can improve the resonant parameters of the two sets of mobile communication antenna elements, thereby increasing the frequency bandwidth of the two sets of mobile communication antenna elements.

[0058] Although the components described above are included in the drawings of this application, it is not excluded that more additional components may be used to achieve better technical effects without departing from the spirit of the invention.

[0059] While the present invention has been described using the above embodiments, it should be noted that these descriptions are not intended to limit the invention. Rather, this invention encompasses modifications and similar arrangements that are obvious to those skilled in the art. Therefore, the scope of the claims should be interpreted in the broadest possible sense to include all obvious modifications and similar arrangements.
