Detailed Implementation

[0006] The integrated antenna system and electronic device proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to facilitate and clarify the illustration of the embodiments of this invention. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different figures may emphasize different aspects and sometimes use different scales. like Figure 1As shown, the present invention provides an integrated antenna system, which includes a radiating antenna module 10, a communication module 20, and a power supply module 30. The power supply module 30 drives the radiating antenna module 10 or the communication module 20. The radiating antenna module 10 is electrically connected to the communication module 20. The radiating antenna module 10 includes a motherboard, a first radiating antenna 11, a second radiating antenna 12, and a third radiating antenna 13. The first radiating antenna 11, the second radiating antenna 12, and the third radiating antenna 13 are all disposed on the motherboard. The first radiating antenna 11 is perpendicular to the motherboard. The second radiating antenna 12 and the third radiating antenna 13 are respectively located on both sides of the motherboard. The communication module 20 is located between the second radiating antenna 12 and the third radiating antenna 13. This configuration not only optimizes antenna layout and structural design, reducing overall size, but also significantly improves antenna performance, enhancing device reliability and adaptability. In other words, optimized antenna layout and structural design significantly improve antenna performance. The system employs a combination of multi-radiating antenna modules 10, effectively reducing mutual interference between antennas and improving radiation efficiency and signal stability. Furthermore, by integrating the antenna modules with the communication module 20 and power module 30, not only is the overall size reduced, but the device's reliability and adaptability are also enhanced. In addition, this solution meets the requirements of communication, positioning, and short-range transmission while also considering miniaturization and integration, providing a new technological path for the development of IoT terminal devices. Furthermore, the first radiating antenna 11 and the motherboard form an L-shaped three-dimensional structure perpendicular to each other. This vertical connection between the first radiating antenna 11 and the motherboard not only improves space utilization but also optimizes the signal transmission path and reduces signal loss. This design further enhances the overall performance of the antenna, especially in high-frequency applications. In addition, the L-shaped structure helps reduce the space occupied by the antenna module within the device, providing greater flexibility for the layout of other functional components. Furthermore, the motherboard is rectangular, and the first radiating antenna 11 is arranged in a rectangular, sheet-like shape, located near the long side of the motherboard. This arrangement provides a stable foundation for the overall layout of the antenna system, while the placement of the sheet-like rectangular first radiating antenna 11 near the long side of the motherboard effectively reduces signal interference and improves radiation efficiency. This layout not only makes full use of the motherboard space but also ensures compatibility between the antenna module and other components. In addition, by placing the first radiating antenna 11 near the long side, the antenna's directivity and gain performance can be further optimized, thereby enhancing signal coverage and stability. The first radiating antenna 11 includes a feed point 110, a first ground point 111, and a second ground point 112. The first radiating antenna 11 is soldered to the motherboard through the feed point 110. The first radiating antenna 11 is configured as a PCB antenna, and its thickness ranges from 1mm ± 0.1mm. The second radiating antenna 12 is positioned as a GPS antenna, and the GPS antenna is made of ceramic. The second radiating antenna 12 is located near a vertical corner of the motherboard, and the distance between the second radiating antenna 12 and the first radiating antenna 11 ranges from 5mm ± 0.1mm. The third radiating antenna 13 is configured as a Bluetooth antenna, and the Bluetooth antenna is made of ceramic. The third radiating antenna 13 is located at another vertical corner of the motherboard, and the distance between the third radiating antenna 13 and the first radiating antenna 11 ranges from 22mm ± 0.1mm. With this configuration, the radiating antenna module 10, through precise layout and material selection, further improves the transmission quality and stability of signals in each frequency band. The second and third radiating antennas 12 and 13, made of ceramic, are optimized for GPS and Bluetooth bands, respectively. Their compact size and high dielectric constant effectively reduce the space occupied by the antennas while ensuring efficient signal radiation. Furthermore, the first radiating antenna 11 is manufactured using PCB technology, which not only reduces production costs but also improves antenna consistency and reliability. By rationally distributing three different functional radiating antennas on the motherboard and strictly controlling their spacing and positional relationships, the system can significantly reduce interference between signals, thereby meeting the integration requirements of multi-band and multi-functionality. This design is particularly suitable for the miniaturization trend of IoT terminal devices, providing a reliable guarantee for stable communication in complex electromagnetic environments. Furthermore, the radiating antenna module 10 also includes a matching network 113, which is electrically connected to the first radiating antenna 11, the second radiating antenna 12, and the third radiating antenna 13. Preferably, the matching circuit of the present invention is in a parallel-series-parallel configuration, which optimizes impedance matching and current distribution, making its impedance more matched. The parallel-series-parallel matching network 113 can effectively adjust the input impedance of each radiating antenna to match the output impedance of the communication module 20, thereby minimizing signal reflection and power loss. By precisely designing the component parameters of the matching network 113, such as the values ​​of inductance and capacitance, optimal transmission efficiency can be ensured within the target frequency band. In addition, this structure has strong adaptability and can be flexibly adjusted according to the needs of different frequency bands in actual application scenarios, thereby improving the overall performance of the system. At the same time, the presence of the matching network 113 also enhances the robustness of the antenna module to changes in the external environment, maintaining stable signal transmission quality even in complex electromagnetic environments. Furthermore, the first radiating antenna 11 is configured with a control frequency band of 820MHz-960MHz / 1710MHz-2690MHz; the second radiating antenna 12 is configured with a control frequency band of 1575MHz; and the third radiating antenna 13 is configured with a control frequency band of 2400MHz-2500MHz. This configuration allows the integrated antenna system to comprehensively cover the current mainstream communication, positioning, and short-range transmission frequency band requirements. The design of the first radiating antenna 11 accommodates multiple communication frequency bands, meeting the application scenarios of 2G, 3G, 4G, and even some 5G frequency bands; the second radiating antenna 12 focuses on GPS positioning, and its high-precision signal reception capability provides reliable support for navigation and positioning services; the third radiating antenna 13 is optimized for Bluetooth communication, enabling efficient data transmission within the 2.4GHz frequency band. This multi-band collaborative design not only enhances the system's functionality but also avoids interference problems caused by frequency band overlap, laying a solid foundation for the diversified applications of IoT devices. In traditional design schemes, planar antenna layouts are prone to mutual interference, resulting in low radiation efficiency, poor signal stability, and low positioning and communication performance. For example... Figure 2 As shown, in the integrated antenna system of the present invention, the first radiating antenna 11, the second radiating antenna 12 and the third radiating antenna 13 form a three-dimensional layout and partition isolation with the motherboard, which effectively improves the overall radiation efficiency of the antenna, and the radiated signal of the antenna is more stable, and the positioning and communication performance is also relatively improved. Furthermore, by employing a three-dimensional layout and partitioned isolation, the integrated antenna system of this invention achieves efficient integration of multiple frequency bands and functions within a compact space. This design not only avoids the signal interference problems common in traditional planar layouts but also significantly enhances the independence and stability of signals in each frequency band. Especially with the miniaturization trend of IoT devices, this solution can achieve higher performance indicators within limited physical space, meeting the needs of complex application scenarios. Furthermore, the integrated antenna system of this invention demonstrates excellent compatibility and scalability in practical applications. Through optimized design of the radiating antenna module 10, the system can flexibly adapt to different communication protocols and standards, thereby supporting the collaborative operation of multiple wireless technologies. For example, in smart home scenarios, the system can simultaneously handle signal transmissions from different protocols such as Wi-Fi, Bluetooth, and Zigbee, ensuring seamless connectivity between devices. In addition, due to its modular design, the system can be functionally expanded or customized according to specific needs, providing a wide range of application possibilities for different industries. Furthermore, the present invention also provides an electronic device comprising the aforementioned integrated antenna system. By integrating this antenna system into the electronic device, the device's communication capabilities and positioning accuracy can be significantly improved, while reducing overall design complexity and manufacturing costs. For example, in applications such as smart wearable devices, vehicle terminals, or industrial IoT sensors, this electronic device can fully utilize the miniaturization and high-performance characteristics of the integrated antenna system to achieve longer battery life, higher signal stability, and stronger environmental adaptability. In addition, due to the modular design of the antenna system, the assembly and maintenance of the electronic device become more convenient, providing strong support for large-scale production and promotion. The integrated antenna system of this invention, through the vertical arrangement of the first radiating antenna 11 and the motherboard, contrasts with the arrangement of the second radiating antenna 12 and the third radiating antenna 13. This creates a vertical three-dimensional layout and partitioned isolation antenna arrangement, effectively reducing coupling interference between antennas, optimizing the return path, and improving the overall radiation efficiency of the antenna. In other words, the vertical three-dimensional layout utilizes the polarization characteristics of electromagnetic waves to create a ring-shaped coverage of the signal in the horizontal plane, maximizing the horizontal signal strength and coverage area, while adapting to the receiving mode of the terminal device. The partitioned isolation between the first radiating antenna 11, the second radiating antenna 12, and the third radiating antenna 13, through physical location separation and spatial layout optimization, reduces electromagnetic coupling (mutual interference) between antennas, significantly improving the signal independence and overall communication performance of the multi-antenna system. Specifically, it reduces antenna mutual coupling, improves isolation, and optimizes the complementarity of radiation patterns. Furthermore, through its vertical three-dimensional layout and partitioned isolation design, this antenna system can better adapt to complex electromagnetic environments. The performance of multi-antenna systems is often limited by mutual coupling effects, but this invention effectively alleviates this problem through precise spatial layout and physical isolation. The vertical placement of the first radiating antenna 11 not only optimizes the signal polarization direction but also reduces electromagnetic interference with other antennas. Simultaneously, the design of the second radiating antenna 12 and the third radiating antenna 13, located on opposite sides of the motherboard, further enhances the isolation between antennas, thereby improving the overall communication quality of the system. This design is particularly suitable for scenarios requiring high-density antenna integration, such as smart terminal devices or IoT nodes, enabling multi-band, multi-functional wireless communication within limited space. In addition, by optimizing the return path, the system significantly reduces signal transmission losses, improves energy efficiency, and provides strong support for low-power operation of the device. In summary, this invention provides an integrated antenna system and electronic device. The integrated antenna system includes a radiating antenna module 10, a communication module 20, and a power supply module 30. The power supply module 30 powers either the radiating antenna module 10 or the communication module 20. The radiating antenna module 10 is electrically connected to the communication module 20. The radiating antenna module 10 includes a motherboard, a first radiating antenna 11, a second radiating antenna 12, and a third radiating antenna 13. The first radiating antenna 11, the second radiating antenna 12, and the third radiating antenna 13 are all mounted on the motherboard. The first radiating antenna 11 is perpendicular to the motherboard, and the second radiating antenna 12 and the third radiating antenna 13 are located on opposite sides of the motherboard. The communication module 20 is located between the second radiating antenna 12 and the third radiating antenna 13. This integrated antenna system not only optimizes antenna layout and structural design, reducing overall size, but also significantly improves antenna performance, enhancing the reliability and adaptability of the device. The design of this integrated antenna system also fully considers the feasibility of manufacturing processes and cost control. By adopting standardized PCB manufacturing processes and ceramic antenna modules, the production process is simplified, and material and processing costs are significantly reduced. Meanwhile, the connection methods between modules are carefully designed to ensure rapid assembly and high yield rates in mass production. Furthermore, to adapt to the needs of different electronic devices, the system offers flexible configuration options.
