Description

In order to meet the growing demand for bandwidth, modern communication systems have increasingly high requirements for the number of antennas, and the demand for antenna frequency bands is also increasingly diversified. Therefore, communication systems have higher requirements for the number of antennas and integration.

In order to overcome these problems, combined antennas have gradually emerged.

[0004] However, existing combined antennas, such as five-in-one and four-in-one, although to some extent solve the demand for multiple antennas, but the number of antennas is still difficult to meet the growing demand of modern communication systems. In addition, a few seven-in-one antennas on the market can provide more antenna functions, but these antennas often have a large size and limited frequency bands, and are usually only suitable for certain specific communication systems.

DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application. It should be noted that the various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the protection scope of the present application, without conflict.

[0030] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of the application is usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0032] In addition, the terms "horizontal", "vertical" and the like do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0033] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] One aspect of this application provides a highly integrated combined antenna to effectively solve the isolation and space occupation problems in multi-antenna systems through reasonable antenna layout and structural design. The combined antenna mainly consists of a first PCB board 10 and an antenna assembly 20, wherein the antenna assembly 20 includes a GNSS antenna 21, multiple main antennas, and multiple MIMO antennas 23. Different types of antennas are arranged in a bidirectional staggered configuration to optimize space utilization and improve the isolation performance between antennas.

[0035] Specifically, such as Figure 1 As shown, the GNSS antenna 21 and multiple main antennas are arranged along a first direction a (e.g., the length direction of the first PCB board 10), and the multiple main antennas are symmetrically distributed on both sides of the GNSS antenna 21 along a second direction b (e.g., the width direction of the first PCB board 10) perpendicular to the first direction a. Simultaneously, the GNSS antenna 21 and multiple MIMO antennas 23 are arranged along the second direction b, while the multiple MIMO antennas 23 are arranged in a staggered manner along the first direction a. By placing the GNSS antenna 21 at the center and symmetrically arranging the main antennas around it, the radiation characteristics of the antennas can be effectively utilized, reducing mutual interference. Secondly, the staggered arrangement design of the MIMO antennas 23 can break the limitations of traditional parallel arrangement, reducing the coupling effect between antennas through spatial position differences. Finally, the bidirectional arrangement structure can fully utilize three-dimensional space, achieving a compact layout of multiple antennas within a limited area.

[0036] Overall, through optimized spatial layout and structural design, multiple antennas can be integrated while maintaining a small size, significantly improving isolation between antennas and reducing mutual interference, allowing each antenna element to fully leverage its performance advantages. This design not only meets the multi-band and multi-functional requirements of modern communication systems but also greatly reduces the overall size of the antenna, making it adaptable to various space-constrained applications such as mobile terminals and portable devices. Simultaneously, the symmetrical and staggered arrangement ensures stable antenna radiation performance, providing strong support for the reliability and performance of the communication system.

[0037] Optionally, the frequency coverage range of the multiple main antennas is 600MHz-960MHz and 1400MHz-6000MHz, which includes frequency bands for multiple standards such as 4G LTE, 5G NR, WiFi, V2X, and GPS. The frequency coverage range of the multiple MIMO antennas 23 is 1400MHz-6000MHz, which also includes frequency bands for multiple standards such as 4G LTE, 5G NR, WiFi, V2X, and GPS. The frequency coverage range of the GNSS antenna 21 is the GPS L1 band, GPS L5 band, and BDS B1 band. It should be understood that the frequency coverage range of the GNSS antenna 21 is adjustable; it can cover the GPS L1 band, GPS L5 band, and BDS B1 band, or it can cover only one of these bands.

[0038] Optionally, such as Figure 1 As shown, the multiple Main antennas include multiple First Main antennas 221 and multiple Second Main antennas 222. The multiple First Main antennas 221 are symmetrically arranged on both sides of the GNSS antenna 21 in the second direction b, forming a first-level symmetrical structure. The multiple Second Main antennas 222 are symmetrically arranged on both sides of the GNSS antenna 21 in the second direction b, forming a second-level symmetrical structure. The First Main antennas 221 are located on the side of the Second Main antennas 222 away from the GNSS antenna 21. This hierarchical symmetrical layout not only optimizes space utilization but also effectively reduces mutual interference between antennas through physical isolation.

[0039] Specifically, a hierarchical symmetrical arrangement is adopted, increasing the physical distance between antennas to reduce electromagnetic coupling effects. Furthermore, placing antennas of the same frequency independently allows for improved signal reception quality through spatial diversity techniques. In addition, optimizing antenna placement creates multiple independent communication channels, increasing system capacity. Appropriate spacing is maintained between the main antennas, and they are connected to the RF front-end circuitry via a precise impedance matching network. For frequency allocation, frequency reuse techniques can be employed, placing antennas of the same frequency diagonally to further reduce interference. It should be understood that since the first Main antenna 221 is located at the edge of the first PCB board 10 along the first direction, it provides greater layout freedom and allows for the design of a longer antenna structure to effectively support radiation and reception performance in both high-frequency (1400MHz-6000MHz) and low-frequency (600MHz-960MHz) bands. In contrast, the second Main antenna 222 is located in the middle area of ​​the first PCB board 10 along the first direction. Due to the limitations of overall size and layout, although it can support radiation and reception performance in both high-frequency and low-frequency bands, its performance in the low-frequency band will be relatively weak, in order to achieve a balance between size and performance within a limited space.

[0040] Optionally, such as Figure 2 As shown, the first main antenna 221 includes an L-shaped radiator 2211 and an L-shaped reference ground 2212, respectively connected to both ends of the first PCB board 10 along the second direction b. The L-shaped radiator 2211 can be formed by welding a vertically arranged second PCB board to a horizontally arranged steel sheet, and the L-shaped reference ground 2212 can be made of an L-shaped steel sheet. The vertical section of the L-shaped radiator 2211 is welded perpendicularly to the plane of the first PCB board 10, and the horizontal section radiates outward parallel to the surface of the first PCB board 10. The L-shaped reference ground 2212 is arranged in a mirror-symmetrical manner, and the ends of the horizontal sections of both are welded to form a complete U-shaped electromagnetic loop. This structural design not only enables a compact layout of the antenna assembly 20, but also optimizes the electromagnetic field distribution through geometric characteristics. The vertical segments of the L-shaped radiator 2211 and the L-shaped reference ground 2212 can be inserted into the grooves at both ends of the first PCB board 10 along the second direction b, and fixed at both ends of the first PCB board 10 by a high-precision welding process to ensure a reliable connection between the first Main antenna 221 and the first PCB board 10, thereby ensuring that the combined antenna has good vibration resistance when used in various electronic devices.

[0041] Optionally, such as Figure 2 As shown, the second Main antenna 222 includes a first radiator 2221 and a second radiator 2222 arranged in an L-shape. The first radiator 2221 is arranged vertically, and the second radiator 2222 is arranged horizontally. Both the first radiator 2221 and the second radiator 2222 can be made using a second PCB board. One end of the first radiator 2221 is inserted into a groove in the first PCB board 10 and is tightly connected to the first PCB board 10 using a high-precision soldering process to ensure a firm contact between the first radiator 2221 and the first PCB board 10, thus ensuring the reliability of signal transmission. The second radiator 2222 is vertically soldered to the other end of the first radiator 2221, forming an L-shaped dual-radiator structure, which enables the second Main antenna 222 to achieve higher radiation efficiency and signal quality in a smaller space. Furthermore, due to the tight welding between the first radiator 2221 and the first PCB board 10, and the tight welding between the second radiator 2222 and the first radiator 2221, the second Main antenna 222 can maintain structural stability and signal transmission reliability when subjected to external vibration or impact, thereby improving the durability of the combined antenna.

[0042] Optionally, such as Figure 2As shown, the MIMO antenna 23 includes a third radiator 231 and a fourth radiator 232 arranged in an L-shape. The third radiator 231 is vertically arranged, and the fourth radiator 232 is horizontally arranged. The third radiator 231 can be a second PCB board, and the fourth radiator 232 can be a steel sheet. The fourth radiator 232 is connected to the first PCB board 10 via the third radiator 231. One end of the third radiator 231 is inserted into a groove in the first PCB board 10 and is tightly connected to the first PCB board 10 using a high-precision soldering process to ensure a firm contact between the third radiator 231 and the first PCB board 10, ensuring reliable signal transmission. The fourth radiator 232 is vertically soldered to the other end of the third radiator 231, forming an L-shaped dual-radiator structure, enabling the MIMO antenna 23 to achieve higher radiation efficiency and signal quality in a smaller space. Furthermore, due to the tight welding between the third radiator 231 and the first PCB board 10, and the tight welding between the fourth radiator 232 and the third radiator 231, the MIMO antenna 23 can maintain structural stability and signal transmission reliability when subjected to external vibration or impact, thereby effectively improving the durability of the combined antenna in various electronic devices.

[0043] Optionally, such as Figure 3 As shown, the first PCB board 10 has a first reference ground 11, multiple second reference grounds 12, and a third reference ground 13 corresponding to antennas at different locations. By setting multiple independent reference grounds on the first PCB board 10, the electromagnetic isolation between each antenna element can be enhanced. Furthermore, the area of ​​each reference ground is relatively large, which not only helps improve signal stability and quality but also reduces signal interference caused by a small reference ground area during electromagnetic wave propagation.

[0044] Specifically, the GNSS antenna 21 and the second Main antenna 222 are connected to the first reference ground 11, while each first Main antenna 221 is individually connected to the corresponding second reference ground 12, ensuring electromagnetic isolation and signal independence between the antennas. The MIMO antenna 23 is connected to the third reference ground 13, where there can be one or more third reference grounds, the specific layout depending on the number of MIMO antennas 23. When there is one third reference ground 13, the third radiators 231 of multiple MIMO antennas 23 are soldered to different positions on that reference ground; if there are multiple third reference grounds 13, and their number is less than the number of MIMO antennas 23, at least one third reference ground 13 will simultaneously have the third radiators 231 of two MIMO antennas 23 soldered to it. This design scheme allows the reference ground of the first PCB board 10 to be fully utilized, increasing the area of ​​the reference ground, and helps to optimize the mutual isolation between antennas, reduce signal interference, and thus improve the overall performance of the system.

[0045] Optionally, as shown in Figures 4 to 7 The combined antenna further comprises a packaging structure, which adopts a split housing design, including a first housing 41 and a second housing 42 sealingly combined with the first housing 41. The first housing 41 and the second housing 42 are combined to form a receiving cavity for accommodating and protecting the first PCB board 10 and the antenna assembly 20, thereby providing reliable physical protection and environmental isolation for the internal electronic components and effectively preventing the intrusion of external factors such as dust and moisture. The reliable fixation between the two housings can be achieved by screw fastening or clamping, and this mechanical connection mode can ensure the structural stability of the packaging structure in harsh environments such as vibration and impact.

[0046] It should be noted that the first housing 41 and the second housing 42 can be made of engineering plastic materials such as polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS). It should be noted that a sealing rubber ring or other sealing material can be provided at the joint of the first housing 41 and the second housing 42 to ensure their sealed connection. The sealing rubber ring is preferably made of high-performance elastic materials such as silicone rubber or fluororubber, which have good weather resistance and sealing performance.

[0047] In the implementation process, the first housing 41 can be designed as a bottom bearing structure with a positioning structure and a mounting groove inside for accurately fixing the first PCB board 10. The second housing 42 is designed as a top cover structure with a sealing groove at its edge for mounting the sealing rubber ring. In the assembly process, the first PCB board 10 and the antenna assembly 20 are first installed and fixed in the first housing 41, then the sealing rubber ring is inserted into the sealing groove of the second housing 42, and finally the second housing 42 is tightly connected with the first housing 41 through threaded fasteners. The threaded connection points can be evenly distributed around the housings, and stainless steel or galvanized screws are used to ensure the reliability and durability of the connection. In addition, double-sided adhesive tape 50 should be attached to the back of the first housing 41 to quickly and reliably fix the combined antenna as a whole in the designated position, avoiding loosening or position deviation of the combined antenna due to external vibration or mechanical interference during use.

[0048] It should be understood that the shape design of the first housing 41 and the second housing 42 follows the principle of coordination with the shape of the first PCB board 10, and the corresponding geometric configuration can be selected according to the specific shape of the first PCB board 10. For a conventional rectangular first PCB board 10, the housing is preferably designed in a rectangular shape, which not only facilitates processing and manufacturing, but also maximizes the use of internal space. For special-shaped first PCB boards 10 such as circular or elliptical, the housing is designed in a corresponding circular or elliptical shape to ensure full use of internal space and compactness of the structure. In addition, in some application scenarios, polygonal or other special-shaped designs can also be used to meet specific installation space requirements or aesthetic needs.

[0049] Optionally, as shown in Figures 4 to 7 The combination antenna also includes a joint cable 30 clamped in the first housing 41. The center conductor at one end of the joint cable 30 is electrically connected to the antenna assembly 20, and the outer conductor is electrically connected to the reference ground of the first PCB board 10. The other end of the joint cable 30 extends outside the first housing 41 and is connected to the electronic device, ensuring the smoothness and stability of signal transmission.

[0050] Specifically, the joint cable 30 adopts an SMA joint cable, which exhibits low signal loss and good connection stability in high-frequency signal transmission. The center conductor is electrically connected to the radiator of the antenna assembly 20, which can ensure that the signal can be effectively transmitted from the antenna to the joint cable 30 and connected to the reference ground of the first PCB board 10 through the outer conductor, forming a stable electromagnetic loop. This design can effectively reduce signal attenuation and interference and ensure efficient operation of the system.

[0051] It should be understood that the number of joint cables 30 should be equal to the number of antennas, and each joint cable 30 is used to connect different antennas. Preferably, the GNSS antenna 21 is connected to a joint cable 30 of model ALSR200, and the Main antenna and the MIMO antenna 23 are connected to joint cables 30 of model RG174. In addition, in order to avoid confusion between joint cables 30, different silk prints can be marked on the heat shrinkable sleeves of different joint cables to facilitate correct connection of corresponding antennas according to actual needs. Such identification not only improves the accuracy and convenience of wiring, but also effectively reduces errors caused by incorrect wiring during installation.

[0052] Optionally, the number of Main antennas is equal to the number of MIMO antennas 23. As shown in Figure 7 In the embodiment of the present application, one GNSS antenna 21, two first Main antennas 221, two second Main antennas 222, and four MIMO antennas 23 are integrated on the first PCB board 10, forming a nine-in-one combination antenna to effectively improve the signal radiation performance.

[0053] Specifically, two first main antennas 221 are symmetrically arranged on both sides of the GNSS antenna 21, and two second main antennas 222 are also symmetrically arranged on both sides of the GNSS antenna 21. The two first main antennas 221 are located at opposite ends of the first PCB board 10 along the first direction a, while the two second main antennas 222 are close to the GNSS antenna 21. Four MIMO antennas 23 are located on one side of the GNSS antenna 21 along the second direction b, and are divided into two groups. The two MIMO antennas 23 in each group are staggered along the first direction a, while the two groups of MIMO antennas 23 are symmetrically arranged along the second direction b, further optimizing the spatial layout of the antennas and improving signal transmission quality and system capacity. Correspondingly, there are nine connector cables 30, each connected to a different antenna. One end of these connector cables 30 is precisely soldered to the antenna and the first PCB board 10, and the other end is connected to the electronic equipment, ensuring stable and efficient signal transmission between the combined antennas and the electronic equipment through an efficient transmission method.

[0054] Preferably, such as Figure 3 As shown, the first PCB board 10 is divided into five independent reference ground regions: one first reference ground 11, two second reference grounds 12, and two third reference grounds 13. The GNSS antenna 21 and the two second main antennas 222 share the same first reference ground 11. This design helps improve the electromagnetic compatibility between the antennas and reduce signal interference. The two first main antennas 221 are connected to two different second reference grounds 12. This layout ensures the independence and signal isolation between these antennas, reduces electromagnetic coupling effects, and improves signal stability and anti-interference capability. Each group of MIMO antennas 23 shares a third reference ground 13, forming a stable electromagnetic loop to ensure that there is no mutual interference during signal transmission.

[0055] Optionally, a GNSS antenna 21, four first Main antennas 221, four second Main antennas 222, and eight MIMO antennas 23 are integrated on the first PCB board 10 to form a seventeen-in-one combined antenna, so as to more effectively improve the radiation performance of the signal.

[0056] In another aspect of this application, an electronic device is provided, including any of the aforementioned combined antennas. Since the electronic device employs the aforementioned combined antenna, it also possesses the same beneficial effects as the combined antenna, which will not be elaborated further here.

[0057] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
