Description

Technical Field

[0001] This application relates to the field of communication equipment technology, and in particular to a multi-band multi-mode integrated antenna device. Background Technology

[0002] With the rapid development of wireless communication technology, especially the advancement of 5G and future 6G communication technologies, the performance requirements of wireless communication systems for antenna equipment are becoming increasingly stringent.

[0003] To meet the needs of more application scenarios, such as high-definition video transmission, large-scale IoT connections, and autonomous driving, highly integrated combined antenna devices or apparatuses have gradually emerged on the market. These devices integrate multiple antennas and related functional modules into a single housing, achieving multi-band, multi-directional, and high-speed wireless signal coverage, greatly improving the flexibility and reliability of communication systems.

[0004] Traditional antenna devices may only support a limited number of feeder connections, which to some extent limits the scalability and flexibility of antenna devices. This application proposes a multi-band multi-mode integrated antenna device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a multi-band multi-mode integrated antenna device to solve the technical problems in the background art.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: a multi-band multi-mode integrated antenna device, including a housing, a positioning unit disposed inside the housing, and a multi-band antenna installed inside the housing, wherein the housing is also provided with a feeder interface group; The housing has two mutually isolated receiving areas inside and a placement area outside the receiving areas; The positioning unit includes two independent antenna modules, which are installed within the container area. The multi-frequency antenna includes multiple radiating antennas, and each radiating antenna is distributed and fixedly placed in the area.

[0007] The feeder interface group is disposed on one side wall of the housing, and the feeder interface group has seven sets of feeder through holes for the feeder connecting the positioning unit and the multi-frequency antenna to pass through respectively.

[0008] By adopting the above technical solution, the feeder interface group is set on one side wall of the housing, and seven sets of feeder through holes are opened to facilitate the passage of feeders connecting the positioning unit and the multi-frequency antenna. This design makes the feeder layout more regular, facilitates installation and maintenance, and also helps to reduce mutual interference between feeders, ensuring the stability of signal transmission.

[0009] In this application, by dividing the internal space into two isolated accommodating areas and a surrounding placement area, effective isolation between the dual positioning unit and the multi-frequency communication antenna is achieved from a physical structure perspective. This design can significantly suppress mutual electromagnetic interference generated when different systems (such as GNSS satellite reception and 4G / 5G high-speed data transmission and reception) are operating, avoiding the problem of decreased receiving sensitivity due to co-location interference, thereby ensuring that each independent functional unit can perform at its best, and especially improving the stability and reliability of the device in complex electromagnetic environments.

[0010] This device integrates two positioning modules (such as GPS and BeiDou) and at least three multi-band communication antennas (such as 5G, 4G, and Wi-Fi) into a single housing. The layout of a "housing area + peripheral placement area" significantly optimizes space utilization, ensuring that multi-functional integration does not come at the expense of device size. Its compact structure makes it suitable for modern applications with strict space constraints, such as in-vehicle smart terminals, drones, and portable communication devices.

[0011] The feeder interface group is located on one side wall of the housing, with seven sets of feeder through holes to facilitate the passage of feeders connecting the positioning unit and the multi-frequency antenna. This design makes the feeder layout more organized, facilitating installation and maintenance, while also helping to reduce mutual interference between feeders and ensuring the stability of signal transmission.

[0012] Furthermore, the housing includes a base plate and a top cover, the accommodating area and the placement area are disposed on the base plate, and a rectangular enclosure formed by a protrusion fixedly connected to the base plate is provided in the accommodating area, and the antenna module is fixedly installed in the rectangular enclosure.

[0013] By adopting the above technical solution, the housing is designed as a combination of a base plate and a top cover, with the accommodating and placement areas located on the base plate. This provides clear and fixed installation positions for the antenna module of the positioning unit and the radiating antenna of the multi-frequency antenna. This design allows for quick and accurate positioning of each component during installation, improving assembly efficiency and reducing performance problems caused by installation position deviations.

[0014] A rectangular enclosure is formed by protrusions fixedly connected to the base plate within the accommodating area. The antenna module is fixedly installed within this rectangular enclosure. The rectangular enclosure provides reliable support and a secure structure for the antenna module, effectively preventing displacement or damage due to vibration, collision, or other factors during use. This enhances the structural stability of the entire device and extends its service life.

[0015] Furthermore, each placement area is provided with a positioning rib fixedly connected to the base plate at one end near the side wall of the base plate, and a right-angle rib fixedly connected to the base plate at the other end. The placement area is also provided with buckles fixedly connected to the base plate on both sides.

[0016] By adopting the above technical solution, the positioning rib located at the end of the placement area near the side wall of the base plate provides a clear lateral positioning reference for the radiating antenna of the multi-frequency antenna. When installing the radiating antenna, simply aligning one end with the positioning rib allows for quick and accurate determination of its lateral position within the placement area, avoiding positional deviations during installation and ensuring that each radiating antenna is installed precisely according to design requirements, thereby guaranteeing the performance stability of the antenna.

[0017] The right-angle rib at the other end not only serves a longitudinal positioning function but also provides stable support for the radiating antenna. The right-angle structure of the rib allows it to fit snugly against the end of the radiating antenna, preventing it from moving or swaying in the longitudinal direction. Simultaneously, the right-angle rib, in conjunction with the positioning rib, forms a relatively enclosed installation space, effectively limiting the radiating antenna and further enhancing its installation stability.

[0018] The clips on both sides of the placement area can clamp and secure the radiating antenna from both sides. The elastic structure of the clips can generate a certain clamping force, firmly fixing the radiating antenna in the placement area and preventing it from loosening or falling off when subjected to external forces such as vibration and impact. This double-sided fixing method is more reliable than single-sided fixing and can effectively improve the installation stability of the radiating antenna.

[0019] Furthermore, positioning posts are fixedly installed around the base plate, and positioning holes that mate with the positioning posts are opened on the top cover.

[0020] By adopting the above technical solution, the positioning posts around the base plate and the positioning holes on the top cover work together to provide precise guidance during the installation of the top cover. Installers only need to align the positioning holes of the top cover with the positioning posts on the base plate and lower it to quickly and accurately position the top cover on the base plate. This avoids installation misalignment caused by human error, ensuring precise alignment between the base plate and the top cover and providing a guarantee for subsequent installation.

[0021] Furthermore, an ultrasonic welding line is provided between the base plate and the top cover.

[0022] Furthermore, the upper cover has a positioning groove for placing ultrasonic welding wires, and the bottom plate has a positioning protrusion that matches the positioning groove.

[0023] By adopting the above technical solution, ultrasonic welding lines utilize high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other, forming a fusion between molecular layers. Setting ultrasonic welding lines between the base plate and the top cover ensures that the welding process is precisely applied to a specific area, resulting in a tight and uniform bond at the weld joint, forming a high-quality fusion, and improving the reliability and stability of the welding process.

[0024] Furthermore, both the base plate and the top cover are made of plastic.

[0025] In summary, this application includes the following beneficial technical effects: This multi-band multi-mode integrated antenna device achieves core beneficial effects such as standardized feeder layout, enhanced anti-interference capability, optimized space utilization, modular expansion support, enhanced environmental adaptability, improved cost-effectiveness, and optimized standardized interoperability by setting seven sets of feeder through holes on the side wall of the housing. The seven sets of through holes are centrally set according to functional zones, allowing the feeders of the positioning unit and the multi-frequency antenna to be independently perforated and connected along a preset path, avoiding cross-entanglement, significantly shortening assembly time and reducing maintenance complexity. At the same time, through the dual design of physical isolation (independent distribution of through holes) and electromagnetic shielding (shielding cover + conductive rubber ring), capacitive coupling and electromagnetic leakage between feeders are effectively suppressed. Within the limited housing space, the partitioned layout of the accommodating area and the placement area, the distributed installation of the radiating antenna, and the design of feeders being located near the through holes reduce the loss of long feeders.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Example, refer to Figure 1 as well as Figure 2A multi-band, multi-mode integrated antenna device includes a housing 1, a positioning unit 3 disposed inside the housing 1, and a multi-band antenna installed inside the housing 1. The housing 1 also has a feeder interface group 4. The housing 1 has two isolated receiving areas and a placement area outside the receiving areas. The positioning unit 3 includes two independent antenna modules installed in the receiving area. The multi-band antenna includes multiple radiating antennas 2, each of which is distributed and fixedly installed in the placement area. The feeder interface group 4 is located on one side wall of the housing 1 and has seven sets of feeder through holes 41 for the feeders 10 connecting the positioning unit 3 and the multi-band antenna to pass through. The housing 1 is box-shaped. Figure 4 The antenna module includes a shielding cover 31 fixedly connected to a PCB board 32 at the bottom of the shielding cover 31, and a ceramic antenna 33 fixed at the bottom of the PCB board 32.

[0030] The feeder interface group 4 is located on one side wall of the housing 1, and seven sets of feeder through holes 41 are provided to facilitate the passage of the feeder 10 connecting the positioning unit 3 and the multi-frequency antenna. This design makes the layout of the feeder 10 more regular, which is convenient for installation and maintenance. At the same time, it also helps to reduce mutual interference between the feeders 10 and ensure the stability of signal transmission.

[0031] In this application, the radiating antenna 2 is used to transmit and / or receive radio frequency signals. Furthermore, all of the multiple radiating antennas 2 in this application can be configured as components adapted to the 5G frequency band, enabling efficient transmission and reception of 5G signals. They possess wide bandwidth characteristics, covering multiple frequency bands of 5G communication, ensuring stable and high-speed data transmission in different scenarios. By optimizing shape and size, signal transmission loss is effectively reduced, antenna gain and directivity are improved, resulting in wider 5G signal coverage and better quality. Similarly, the radiating antennas 2 can also be configured as components suitable for the 4G frequency band. The design fully considers the characteristics of 4G networks, possessing good impedance matching and radiation efficiency. Stable signal transmission and reception can be achieved within the 4G frequency band, meeting users' needs for high-speed mobile data and voice communication. Through reasonable layout and optimized design, the impact of multipath effects and interference on the signal is effectively reduced, improving communication reliability.

[0032] In practical applications, a more common and advantageous approach is to differentiate the configuration of the radiating antenna 2. For example, some radiating antennas 2 are designed for 5G, while others are designed for 4G. This configuration fully leverages the advantages of both 5G and 4G networks, enabling seamless network switching and complementarity. When in areas with good 5G signal coverage, the 5G radiating antenna 2 operates at full capacity, providing users with an ultra-high-speed network experience; while in areas with weak or no 5G signal, the 4G radiating antenna 2 automatically takes over communication tasks, ensuring users remain online at all times. The radiating antenna 2 covers three frequency bands: 5G, 4G, and WiFi. The 5G radiating antenna 2 employs a multi-layered stacked structure and microstrip patch technology to achieve comprehensive coverage of both high-frequency and low-frequency 5G bands, featuring high gain and low loss, meeting the future requirements of 5G communication for high speed, large capacity, and low latency. The 4G radiating antenna 2 uses a traditional monopole or dipole structure, and after optimization, it exhibits excellent radiation performance and impedance matching characteristics within the 4G frequency band, providing users with stable and reliable 4G network services. WiFi radiating antenna 2 is customized according to different WiFi standards (such as 802.11ac, 802.11ax, etc.). It adopts MIMO (Multiple Input Multiple Output) technology and achieves high-speed and stable WiFi signal coverage through the coordinated work of multiple radiating antennas 2, meeting the wireless LAN communication needs of users in indoor environments.

[0033] This application achieves effective isolation between the dual positioning unit 3 and the multi-frequency communication antenna by dividing the internal space into two isolated accommodating areas and a surrounding placement area. This design can significantly suppress mutual electromagnetic interference generated when different systems (such as GNSS satellite reception and 4G / 5G high-speed data transmission and reception) are operating, avoiding the problem of decreased receiving sensitivity due to co-location interference. This ensures that each independent functional unit can perform at its best, and in particular, improves the stability and reliability of the device in complex electromagnetic environments.

[0034] This device integrates two positioning modules (such as GPS and BeiDou) and at least three multi-band communication antennas (such as 5G, 4G, and Wi-Fi) into a single housing 1. The layout of the "accommodation area + peripheral placement area" significantly optimizes space utilization, ensuring that multi-functional integration does not come at the expense of device size. Its compact structure and elegant design make it ideal for modern applications with strict space constraints, such as in-vehicle smart terminals, drones, and portable communication devices.

[0035] In this embodiment, refer to Figure 3The housing 1 includes a base plate 12 and a top cover 11. A receiving area and a placement area are located on the base plate 12. A rectangular enclosure 34, formed by a protrusion fixedly connected to the base plate 12, is provided within the receiving area. The antenna module is fixedly installed within the rectangular enclosure 34. Designing the housing 1 as a combination of the base plate 12 and the top cover 11, and placing the receiving and placement areas on the base plate 12, provides clear and fixed installation positions for the antenna module of the positioning unit 3 and the radiating antenna 2 of the multi-frequency antenna. This design allows for quick and accurate positioning of components during installation, improving assembly efficiency and reducing performance problems caused by installation position deviations.

[0036] A rectangular enclosure 34 is formed by protrusions fixedly connected to the base plate 12 within the accommodating area, and the antenna module is fixedly installed in the rectangular enclosure 34. The rectangular enclosure 34 provides reliable support and fixing structure for the antenna module, which can effectively prevent the antenna module from shifting or being damaged due to vibration, collision or other factors during use, thereby enhancing the structural stability of the entire device and extending the service life of the equipment.

[0037] In this embodiment, the positioning rib 21 provided at one end of the placement area near the side wall of the base plate 12 provides a clear lateral positioning reference for the radiating antenna 2 of the multi-frequency antenna. When installing the radiating antenna 2, simply aligning one end with the positioning rib 21 allows for quick and accurate determination of its lateral position within the placement area, avoiding positional deviations during installation and ensuring that each radiating antenna 2 can be precisely installed according to design requirements, thereby guaranteeing the performance stability of the antenna.

[0038] The right-angle rib 22, fixedly mounted on the base plate 12 at the other end, not only serves a longitudinal positioning function but also provides stable support for the radiating antenna 2. The right-angle structure of the rib 22 allows it to fit snugly against the end of the radiating antenna 2, preventing it from moving or swaying in the longitudinal direction. Simultaneously, the right-angle rib 22, in conjunction with the positioning rib 21, forms a relatively enclosed installation space, effectively limiting the radiating antenna 2 and further enhancing its installation stability.

[0039] The asymmetrically arranged latches 23 on both sides of the placement area can clamp and fix the radiating antenna 2 from both sides. The elastic structure of the latches 23 can generate a certain clamping force to firmly fix the radiating antenna 2 in the placement area, preventing it from loosening or falling off when subjected to external forces such as vibration and impact. This double-sided fixing method is more reliable than single-sided fixing and can effectively improve the installation stability of the radiating antenna 2.

[0040] In this embodiment, positioning posts are fixedly installed around the base plate 12, and positioning holes for docking with the positioning posts are opened on the top cover 11.

[0041] The positioning posts around the base plate 12 cooperate with the positioning holes on the top cover 11, providing precise guidance during the installation of the top cover 11. Installers only need to align the positioning holes of the top cover 11 with the positioning posts of the base plate 12 to quickly and accurately position the top cover 11 on the base plate 12, avoiding installation misalignment caused by human error and ensuring precise alignment between the base plate 12 and the top cover 11, thus providing a guarantee for subsequent installation.

[0042] In this embodiment, an ultrasonic welding line 42 is provided between the base plate 12 and the top cover 11. The top cover 11 has a positioning groove for placing the ultrasonic welding line 42, and the base plate 12 has a positioning protrusion that matches the positioning groove. Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other, forming a fusion between molecular layers. Providing the ultrasonic welding line 42 between the base plate 12 and the top cover 11 ensures that the welding process is precisely applied to a specific area, resulting in a tight and uniform weld joint, forming a high-quality weld joint, effectively avoiding problems such as incomplete welds and missed welds, and improving the reliability and stability of the welding. Both the base plate 12 and the top cover 11 are made of plastic.

[0043] Specific implementation process: When the device needs to transmit radio frequency signals, the main control system generates corresponding digital signals according to communication requirements and transmits them to the feeder interface group 4 of the multi-frequency antenna. The feeder interface group 4 distributes the digital signals to the corresponding radiating antennas 2 through seven sets of feeder through-holes 41. For example, if a 5G signal needs to be transmitted, the main control system will transmit the digital signal to the 5G radiating antenna 2; if a 4G signal needs to be transmitted, it will be transmitted to the 4G radiating antenna 2; if a WiFi signal needs to be transmitted, it will be transmitted to the WiFi radiating antenna 2. After receiving the digital signal, the radiating antenna 2 converts it into a high-frequency electrical signal and radiates it into electromagnetic waves into space through its own radiating structure. The radiating antennas 2 of different frequency bands will transmit electromagnetic waves with specific frequencies, amplitudes, and phases in their respective frequency bands according to their design characteristics to achieve communication with base stations or other devices.

[0044] When the device is in signal receiving mode, electromagnetic waves in the surrounding space reach the radiating antenna 2 of the multi-frequency antenna. The radiating antenna 2, based on its frequency response characteristics, selectively receives electromagnetic waves of the corresponding frequency band. For example, the 5G radiating antenna 2 receives electromagnetic waves of the 5G band, the 4G radiating antenna 2 receives electromagnetic waves of the 4G band, and the WiFi radiating antenna 2 receives electromagnetic waves of the WiFi band. The radiating antenna 2 converts the received electromagnetic waves into high-frequency electrical signals and transmits these signals to the feeder interface group 4 via the feeder 10. The feeder interface group 4 aggregates and performs preliminary processing on the received electrical signals before transmitting them to the main control system. The main control system further demodulates and decodes the electrical signals to restore the original digital signals, thereby enabling information interaction with the base station or other devices.

[0045] In practical applications, the device automatically switches and complements networks based on changes in the surrounding network environment. When in an area with good 5G signal coverage, the main control system prioritizes activating the 5G radiating antenna 2, ensuring it operates at full capacity to provide users with an ultra-high-speed network experience. At this time, the 4G radiating antenna 2 is in standby mode but still monitors the 4G signal strength in real time. If the user moves to an area with weak or no 5G signal, the main control system immediately detects the change in 5G signal and quickly switches to the 4G radiating antenna 2, allowing it to automatically take over communication tasks and ensure the user remains online at all times. This network switching process is automatic and seamless; users will hardly notice any network interruption or change. Simultaneously, the WiFi radiating antenna 2 automatically searches for and connects to available WiFi networks based on the user's environment, providing faster and more stable local wireless LAN communication services, further enriching the user's communication options and improving communication flexibility and reliability.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
