Description

Technical Field

[0001] This utility model relates to the field of antenna technology, and more specifically, to a GNSS antenna and communication equipment. Background Technology

[0002] With the rapid development of GNSS (Global Navigation Satellite System) technology, high-precision positioning is increasingly being used in surveying and mapping, intelligent driving, and unmanned aerial vehicles (UAVs). As the first link in receiving satellite signals, the performance of the antenna directly determines the final positioning accuracy; therefore, the design and manufacturing of high-performance GNSS antennas are of paramount importance.

[0003] Currently, mainstream high-precision GNSS antennas on the market, especially microstrip patch antennas, typically rely heavily on high-performance dielectric substrates, such as polyphenylene oxide (PPO), polytetrafluoroethylene (F4B), or ceramics, to achieve the required electrical performance, ensuring stable resonant frequencies and high radiation efficiency. However, these dielectric materials significantly increase antenna costs. Furthermore, to achieve multi-band operation, complex structures with multiple dielectric layers are often required, further increasing manufacturing costs and design complexity, and resulting in a heavier overall antenna weight. Utility Model Content

[0004] The purpose of this invention is to provide a GNSS antenna and communication device that can reduce manufacturing costs while maintaining high positioning accuracy and achieve lightweight antenna structure.

[0005] The embodiments of this utility model are implemented as follows: In one aspect, this utility model provides a GNSS antenna, including an antenna radiator and a circuit board; the antenna radiator and the circuit board are connected by at least four support members, any two support members are arranged at intervals, and the multiple support members are arranged in a centrally symmetrical manner around the center of the antenna radiator; conductive lines are provided on the surface of at least four support members, and the conductive lines are used to electrically connect the antenna radiator and the circuit board.

[0006] Optionally, the support member has a first positioning structure protruding toward the antenna radiator, and the antenna radiator is provided with a first limiting groove adapted to the first positioning structure, and the first positioning structure is engaged in the first limiting groove.

[0008] Optionally, the support includes a first support and a second support. The surface of the first support is not provided with conductive lines, while the surface of the second support is provided with conductive lines. There are multiple support members, which are arranged in a ring at intervals, and the first support and the second support are alternately arranged.

[0009] Optionally, the GNSS antenna also includes a cable assembly, one end of which is electrically connected to the circuit board and the other end of which is used to connect to an external device.

[0010] Optionally, the GNSS antenna also includes a shielding cover, which is placed on the side of the circuit board away from the antenna radiator; the side wall of the shielding cover has through holes for cable assemblies to pass through.

[0012] Optionally, the GNSS antenna also includes a plug-in element, which passes through the antenna radiator and the circuit board in sequence and is electrically connected to the antenna radiator and the circuit board respectively.

[0013] Optionally, the material of the support is FR-4 epoxy glass cloth board.

[0014] Another aspect of this utility model provides a communication device that includes a GNSS antenna.

[0015] The beneficial effects of this utility model include: This application provides a GNSS antenna, including an antenna radiator and a circuit board. The antenna radiator and the circuit board are connected by at least four support members, providing stable support for the antenna radiator and preventing deformation or displacement due to its own weight or slight external vibrations. This ensures the relative positional accuracy between the radiator and the circuit board, thereby guaranteeing the stability of key electrical performance parameters such as antenna resonant frequency and beamwidth. Any two support members are spaced apart, forming a spatial structure with air as the primary medium, replacing expensive solid dielectric carriers such as PPO, F4B, and ceramics used in traditional high-precision antennas. Air has a stable dielectric constant and extremely low cost, solving the high cost problem associated with traditional dielectric materials and reducing the overall weight of the antenna, achieving lightweight antenna structure. Multiple support members are arranged symmetrically around the center of the antenna radiator, ensuring consistency in electromagnetic field disturbances at all azimuth angles, thus maintaining the high performance of the GNSS antenna and ensuring accuracy and reliability. Conductive lines are provided on the surfaces of at least four support members, which electrically connect the antenna radiator and the circuit board, allowing precise control of the current distribution in the antenna radiator, enabling the antenna radiator to generate high-frequency and low-frequency resonances respectively. This configuration eliminates the need for traditional multi-layer dielectric stacking structures to achieve multi-band operation. Multi-band operation can be achieved using only a single-layer radiator and conductive circuitry, significantly simplifying antenna structure design and reducing the manufacturing costs and design complexity associated with multi-layer stacking. The aforementioned GNSS antenna maintains high positioning accuracy while reducing manufacturing costs and achieving a lightweight antenna structure. Attached Figure Description

[0024] Please refer to Figure 1 This embodiment provides a GNSS antenna 100, including an antenna radiator 110 and a circuit board 120; the antenna radiator 110 and the circuit board 120 are connected by at least four support members 130, any two support members 130 are arranged at intervals, and the multiple support members 130 are arranged in a centrally symmetrical manner around the center of the antenna radiator 110; conductive lines 130a are provided on the surface of at least four support members 130, and the conductive lines 130a are used to electrically connect the antenna radiator 110 and the circuit board 120.

[0025] Specifically, the antenna radiator 110 is a core functional component for receiving and radiating GNSS satellite signals. In one specific embodiment of this application, such as... Figure 1 and Figure 2 As shown, the antenna radiator 110 has a disk-shaped structure. The circuit board 120 serves as the core carrier for signal processing and transmission, integrating key circuits such as signal amplification, filtering, and demodulation. It is responsible for converting the weak satellite signals received by the antenna radiator 110 into identifiable positioning data and enabling signal interaction with external devices.

[0026] The antenna radiator 110 is connected to the circuit board 120 via a support member 130. In one specific embodiment of this application, the antenna radiator 110 and the circuit board 120 have pre-reserved solder pads 170, which are used to fix the antenna radiator to the support member 130 by soldering. Preferably, the support member 130 has a rectangular block structure. The antenna radiator 110 and the circuit board 120 are connected by at least four support members 130 to ensure the balance of the support and avoid tilting or uneven force on the radiator caused by a single support member 130.

[0027] The arrangement of any two support members 130 at intervals creates a spatial structure with air as the primary filling medium between the antenna radiator 110 and the circuit board 120. Multiple support members 130 are arranged symmetrically around the center of the antenna radiator 110, ensuring consistent electrical performance of the GNSS antenna 100 across all azimuth angles and maintaining its high performance. The structural support provided by the support members 130 creates an air-based structure between the antenna radiator 110 and the circuit board 120, allowing signal transmission between the radiator and the circuit board 120 to primarily rely on air. Compared to traditional high-precision GNSS antennas that rely on expensive solid media such as PPO, F4B, and ceramics, air significantly reduces material costs. Furthermore, compared to high-density solid media, air significantly reduces the overall weight of the antenna.

[0028] In this embodiment, the antenna radiator 110 has four feed points. Therefore, at least four of the support members 130 are provided with conductive lines 130a. Each conductive line 130a of the support member 130 is electrically connected to one of the four feed points, ensuring that the electrical length and impedance environment of each feed point path are highly consistent. This ensures the consistency of multi-band signal excitation and improves the performance of the GNSS antenna 100. The conductive line 130a is a metal wire etched or printed on the surface of the support member 130. One end of it is connected to the signal feed point of the antenna radiator 110, and the other end is connected to the signal interface of the circuit board 120. It should be noted that the direction, length, width, and other parameters of the conductive line 130a can be set according to actual needs. By adjusting the specific parameters of the conductive line 130a, the current distribution of the radiator can be changed, enabling the radiator to excite high-frequency and low-frequency resonances respectively, thereby realizing multi-band signal reception and improving positioning accuracy. In addition, the conductive line 130a not only performs the function of signal transmission, but also serves as an impedance matching adjustment channel to optimize the signal transmission efficiency between the radiator and the circuit board 120.

[0029] By setting conductive lines 130a on the support 130 to regulate the resonant characteristics of the radiator, the multi-layer dielectric stacking structure of traditional antennas is eliminated. High and low frequency signals can be received with only a single-layer radiator, which greatly simplifies the antenna's structural design and assembly process and reduces the material cost and process difficulty caused by multi-layer stacking.

[0030] It should be noted that the support member 130 includes a first support member 133 and a second support member 134, such as... Figure 4 As shown, the surface of the first support member 133 does not have conductive lines 130a, and only serves a supporting function; as Figure 5As shown, the surface of the second support member 134 is provided with conductive lines 130a, which serve the dual functions of structural support and electrical connection; there are multiple support members 130, which are arranged in a ring at intervals. In one specific embodiment of this application, as shown... Figure 2 and Figure 3 As shown, there are eight support members 130, including four first support members 133 and four second support members 134, to avoid tilting or deformation of the radiator caused by localized force concentration; and the alternating arrangement of the first support members 133 and the second support members 134 ensures that the conductive lines 130a of the second support members 134 are evenly distributed on the ring path, ensuring that the signal transmission point is accurately matched with the current distribution area of ​​the radiator.

[0031] Optionally, the support component 130 is made of FR-4 epoxy glass cloth. This material is low in cost and easy to process, and contains no additional conductive material, which avoids interference from extra metal lines to the antenna radiation field, ensuring that the support function is pure and stable.

[0032] The GNSS antenna 100 includes an antenna radiator 110 and a circuit board 120. The antenna radiator 110 and the circuit board 120 are connected by at least four support members 130, which can provide stable support for the antenna radiator 110, prevent the radiator from deforming or shifting due to its own weight or slight external vibrations, ensure the relative positional accuracy between the radiator and the circuit board 120, and thus ensure the stability of key electrical performance such as antenna resonant frequency and beamwidth. Any two support members 130 are arranged at intervals to form a spatial structure with air as the main medium, replacing the expensive solid medium carriers such as PPO, F4B, and ceramics in traditional high-precision antennas. Air, with its stable dielectric constant and extremely low cost, solves the high cost problem associated with traditional dielectric materials, while also reducing the overall weight of the antenna and achieving a lightweight antenna structure. Multiple support components are arranged symmetrically around the center of the antenna radiator, ensuring consistency in electromagnetic field disturbances at all azimuth angles, thus maintaining the high performance of the GNSS antenna and ensuring accuracy and reliability. Conductive lines 130a are provided on the surfaces of at least four support components 130. These conductive lines 130a electrically connect the antenna radiator 110 and the circuit board 120, allowing precise control of the current distribution in the antenna radiator 110, enabling it to generate high-frequency and low-frequency resonances. This arrangement eliminates the need for traditional multi-layer dielectric stacking structures for multi-band operation; a single-layer radiator combined with conductive lines 130a is sufficient, significantly simplifying the antenna structure design and reducing the manufacturing costs and design complexity associated with multi-layer stacking. The aforementioned GNSS antenna 100 achieves high positioning accuracy while reducing manufacturing costs and achieving a lightweight antenna structure.

[0033] For example, such as Figure 3 and Figure 4 As shown, the support member 130 has a first positioning structure 131 protruding to one side of the antenna radiator 110. The antenna radiator 110 is provided with a first limiting groove 111 that is adapted to the first positioning structure 131. The first positioning structure 131 is engaged in the first limiting groove 111.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, the first positioning structure 131 is a rectangular sheet-like protrusion. Correspondingly, the antenna radiator 110 is provided with a first limiting groove 111 adapted to the rectangular protrusion structure. The first positioning structure 131 is engaged within the first limiting groove 111 and welded to the antenna radiator 110. Of course, besides the rectangular sheet-like protrusion, the first positioning structure 131 can also be in other forms, such as a cylindrical protrusion, etc. This application does not impose any limitations on this. Figure 4 As shown, the surface of the first positioning structure 131 is provided with a solder pad 170 for soldering to the antenna radiator 110.

[0035] It should be noted that the first limiting groove 111 is only opened in the non-functional area of ​​the antenna radiator 110, which can avoid interference with the patch shape and current path of the radiator and ensure that the core electrical performance of the radiator, such as the resonant frequency and radiation efficiency, is not affected by the positioning structure.

[0036] For example, such as Figure 3 and Figure 5 As shown, the support member 130 has a second positioning structure 132 protruding to one side of the circuit board 120. The circuit board 120 is provided with a second limiting groove 121 that is adapted to the second positioning structure 132. The second positioning structure 132 is engaged in the second limiting groove 121.

[0037] Specifically, such as Figure 3 and Figure 5 As shown, the second positioning structure 132 is a rectangular sheet-like protrusion. Correspondingly, the circuit board 120 is provided with a second limiting groove 121 adapted to the rectangular protrusion structure. The second positioning structure 132 is engaged within the second limiting groove 121 and soldered to the circuit board 120. Of course, besides the rectangular sheet-like protrusion, the second positioning structure 132 can also be in other forms, such as a cylindrical protrusion, etc. This application does not impose any limitations on this. Figure 5 As shown, the surface of the second positioning structure 132 is provided with pads 170 for soldering to the circuit board 120. Similarly, the second limiting groove 121 is only formed in the non-functional area of ​​the circuit board.

[0038] By setting the first positioning structure 131 and the second positioning structure 132, the assembly error range of the support 130 can be reduced, ensuring that the relative position deviation between the radiator and the support 130 is controlled within the design allowable range, thereby improving the accuracy of the GNSS antenna 100.

[0039] Optionally, such as Figure 2 and Figure 3 As shown, the GNSS antenna 100 also includes a cable assembly 140, one end of which is electrically connected to the circuit board 120 and the other end is used to connect to an external device.

[0040] Specifically, the cable assembly 140 serves as an extension structure for signal output, with one end connected to the signal interface of the circuit board 120 and the other end connected to an external device. An insulating protective sleeve may be additionally provided at the connection point to prevent short circuits with structures such as the support member 130. Preferably, the cable assembly 140 uses shielded cable to reduce signal interference and improve the stability of signal transmission from the GNSS antenna 100.

[0041] When the GNSS antenna 100 is close to an external device, the cable assembly 140 can be omitted and the connection can be made directly through the interface of the circuit board 120. When the distance is far, remote signal transmission can be achieved by assembling cable assemblies 140 of different lengths without modifying the core structure of the GNSS antenna 100, which greatly expands the antenna's adaptability in different scenarios such as surveying and mapping, drones, and intelligent driving.

[0042] In one possible implementation of this application, such as Figure 3 As shown, the GNSS antenna 100 also includes a shield 150, which covers the side of the circuit board 120 away from the antenna radiator 110; the side wall of the shield 150 is provided with a through hole 151 for passing through the cable assembly 140.

[0043] Specifically, such as Figure 3 As shown, the shielding cover 150 is a rectangular frame structure supported by a metal material, such as aluminum alloy. It is arranged in a surrounding manner on the side of the circuit board 120 opposite to the antenna radiator 110, and can be fixed to the circuit board 120 by welding, clips, or screws. The shielding cover 150 does not directly contact the support member 130 or the radiator, thus avoiding interference with the signal reception of the radiator.

[0044] Circuit board 120 integrates key circuits for GNSS signal amplification, filtering, and demodulation. The satellite signals processed by these circuits are extremely weak and susceptible to interference from the external electromagnetic environment. The metal shield 150, based on the principle of electromagnetic shielding, can block external interference signals from entering the shield and affecting the operation of circuit board 120. At the same time, it prevents the electromagnetic radiation generated by the circuit board 120 itself from spreading outward and interfering with other components, directly ensuring the accuracy of signal processing and improving signal processing precision.

[0045] like Figure 3As shown, the side wall of the shield 150 is provided with a through hole 151 for the cable assembly 140 to pass through. The through hole 151 provides a passage for the cable assembly 140 to pass through, which not only meets the functional requirements of connecting the cable to external equipment, but also minimizes the opening area of ​​the shield 150, ensuring that the circuit board 120 is in a stable electromagnetic environment while realizing signal output.

[0046] Optionally, such as Figure 3 As shown, the shielding cover 150 has a limiting protrusion 152 protruding on the side facing the circuit board 120, and the circuit board 120 has a limiting hole that matches the limiting protrusion 152. Preferably, the limiting protrusion 152 has a rectangular block structure and is integrally manufactured with the shielding cover 150 to ensure that the protrusion has sufficient structural strength and avoids breakage during assembly; the position of the protrusion must correspond one-to-one with the preset position of the limiting hole on the circuit board 120. There are multiple limiting protrusions 152. Preferably, each sidewall of the shielding cover 150 has at least one limiting protrusion 152 to improve the stability of the connection with the circuit board 120.

[0047] Optionally, such as Figure 3 As shown, the GNSS antenna 100 also includes a plug-in element 160, which passes through the antenna radiator 110 and the circuit board 120 in sequence and is electrically connected to the antenna radiator 110 and the circuit board 120 respectively.

[0048] Specifically, the plug-in element 160 is a columnar or needle-shaped structure with conductive properties. Its material is preferably a metal with excellent conductivity, such as brass or phosphor bronze, and its surface can be gold-plated to reduce contact resistance.

[0049] The plug-in element 160 serves as the electrical connection channel between the antenna radiator 110 and the circuit board 120, and its placement avoids the assembly area of ​​the support member 130. It should be noted that the plug-in element 160 can be flexibly configured to meet different frequency band requirements or signal transmission strength needs. When the conductive line 130a of the second support member 134 cannot meet the requirements of multi-channel signal transmission, the conductive path can be supplemented by adding the plug-in element 160; when the antenna structure needs to be simplified, signal connection can be achieved solely by relying on the second support member 134.

[0050] Compared to indirect transmission relying on the conductive lines 130a on the surface of the support member 130, the plug-in element 160 directly penetrates the radiator and forms a point-to-point electrical connection with the circuit board 120. The low impedance characteristics of the metal material can reduce the attenuation of high-frequency signals during transmission, further enhancing the antenna's high-precision positioning capability.

[0051] Another aspect of this utility model provides a communication device including a GNSS antenna 100. The specific structure and beneficial effects of the GNSS antenna 100 have been described in detail above and will not be repeated here. This communication device, through the installation of the GNSS antenna 100, can possess precise positioning capabilities, reduce production costs, and achieve lightweight and compact structure, thus meeting the miniaturization requirements of communication devices.

[0052] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
