Description

Technical Field

[0001] This utility model relates to the field of wall-mounted antenna technology, specifically a single-polarization wall-mounted antenna. Background Technology

[0002] With the rapid development of communication technology, antennas, as an important component of wireless communication systems, directly affect communication quality and stability. Especially in some special application scenarios, such as the design and use of wall-mounted antennas, not only are efficient radiation characteristics required, but also a good structural design to facilitate installation, disassembly, and maintenance.

[0003] While existing single-polarized wall-mounted antennas offer good radiation characteristics to meet signal transmission requirements, they typically employ reinforced structures to ensure stability and interference resistance after installation. These structures often include multiple mounting components, reinforcing ribs, and thickened shells. While these designs effectively improve antenna stability and shock resistance, they also introduce complexity into installation and maintenance. Specifically, existing single-polarized wall-mounted antennas mostly rely on complex mounting structures, such as multiple screw connections, to ensure stability after installation. These designs make the antenna more stable in practical use, but disassembly and maintenance often require the removal of numerous mounting components. The disassembly process is cumbersome and time-consuming, especially when periodic inspections, component replacements, or maintenance are required. The complex disassembly and assembly process significantly increases labor costs and operational difficulty. Therefore, it is necessary to provide a single-polarized wall-mounted antenna that offers abundant frequency band resources for selection and allocation, and is easy to disassemble, install, and maintain.

Detailed Implementation

[0020] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] See Figure 1 as well as Figure 2 This embodiment provides a single-polarization wall-mounted antenna, which includes a housing and an antenna body 30 installed inside the housing.

[0022] Specifically, the housing includes an antenna cover 10 and a cover plate 20. Both the antenna cover 10 and the cover plate 20 are hollow cuboid structures with an opening on one side. The outer periphery of the side wall of the antenna cover 10 is provided with a mounting groove 11, and a rubber ring 12 is provided in the mounting groove 11. The inner side of the side wall of the cover plate 20 is recessed with an annular groove 21 on the outer side. When the antenna cover 10 and the cover plate 20 are closed to form a hollow cuboid structure, the rubber ring 12 is tightened at the annular groove 21. It should be noted that the antenna body 30 of this application is detachably installed on one side of the radome 10, and the cover plate 20 covers the opening side of the radome 10. When the radome 10 and the cover plate 20 are fastened together, the opening side of the cover plate 20 and the opening side of the radome 10 are close to each other. Since the outer diameter of the side wall of the radome 10 is smaller than the inner diameter of the side wall of the cover plate 20, the inside of the side wall of the cover plate 20 will abut against the outside of the side wall of the radome 10. When the radome 10 is pressed into the cover plate 20, when the rubber ring 12 reaches the annular groove 21, the rubber ring 12 and the annular groove 21 are tightly connected. At this time, the radome 10 and the cover plate 20 are tightly installed. It should also be noted that when installing the single-polarization wall-mounted antenna of this application, the cover plate 20 is fixed to the wall with screws, and then the radome 10 is fastened to the cover plate 20 which is installed on the wall with screws or in other positions by pressing it firmly. When disassembly is required, the antenna cover 10 can be removed by pulling the antenna cover 10 outward to disengage the rubber ring 12 from the annular groove 21. Then, maintenance and other operations can be performed on the antenna body 30 inside the antenna cover 10. After maintenance is completed, press it back onto the cover plate 20.

[0023] Specifically, the antenna body 30 is disposed inside the radome 10. The antenna body 30 includes a first radiating element 31, a second radiating element 32, a first coupling plate 33, a second coupling plate 34, a third coupling plate 35, a cable 36, and a reflector 37. The first radiating element 31 and the second radiating element 32 form an asymmetric antenna dipole antenna body 30. The first coupling plate 33 and the second radiating element 32 form an asymmetric structure. The second coupling plate 34 and the third coupling plate 35 are located on the left and right sides of the angle formed by the first radiating element 31 and the second radiating element 32, respectively. The shielding mesh of the cable 36 is connected to the second radiating element 32. The core wire of the cable 36 is welded to the first radiating element 31 to form a coaxial cable for power supply. The reflector 37 is installed on the side of the radome 10 near the cover plate 20. First, the combination of the first radiating element 31 and the second radiating element 32 through an asymmetric dipole structure broadens the antenna's operating frequency range, improving radiation efficiency and signal coverage. The arrangement of the three coupling plates further enhances the antenna's radiation performance and frequency band utilization efficiency, particularly in applications requiring wide bandwidth and high gain. Second, the coaxial feeding method of the cable 36 effectively reduces signal loss during transmission, and the connection between the shielding mesh and the core wire ensures signal stability and clarity. The reflector 37 improves the antenna's directivity and forward gain, reduces backward radiation, and further optimizes the antenna's radiation pattern. Therefore, it not only ensures the antenna's high efficiency but also makes it adaptable to various application scenarios, providing stronger network performance and wider coverage.

[0024] Preferably, the radome 10 and the cover plate 20 are integrally injection molded from environmentally friendly insulating plastic. Environmentally friendly insulating plastic material has strong weather resistance and UV resistance, enabling it to be used outdoors and in harsh environments for extended periods without degradation. Furthermore, the integral injection molding process not only improves production efficiency but also ensures a tight fit between the radome 10 and the cover plate 20, enhancing the overall stability and durability of the product.

[0025] Preferably, the radome 10 includes a square base plate 13 and four bottom side plates 14 connected end-to-end to the side of the square base plate 13. A top side plate 15 is connected to the bottom side plate 14 on the side away from the square base plate 13. The gap between the outer walls of two opposite top side plates 15 is smaller than the gap between the outer walls of two opposite bottom side plates 14. The four top side plates 15 are provided with mounting grooves 11. The cover plate 20 includes a square cover plate base plate 22 and four cover plate side plates 23 connected end-to-end to the side of the square cover plate base plate 22. The inner gap between two opposite cover plate side plates 23 is slightly larger than the gap between two opposite top side plates 15 during installation. The outer gap between two opposite cover plate side plates 23 is equal to the gap between two opposite bottom side plates 14 during installation. The inner side of the cover plate side plate 23 is provided with an annular groove 21. The above-mentioned structure ensures that after the radome 10 and the cover plate 20 are fastened together, they can be combined into a cuboid structure with the side plates flush, which helps to improve the assembly quality of the product, makes the assembly seamless, and ensures the neatness and beauty of the overall appearance.

[0026] Furthermore, the inner sides of the bottom side plate 14, the top side plate 15, and the cover plate 23 are all provided with a predetermined number of transverse reinforcing ribs and a predetermined number of vertical reinforcing ribs perpendicular to the transverse reinforcing ribs. The design of the transverse and vertical reinforcing ribs effectively ensures the structural strength of the radome 10 and the cover plate 20, while also reducing material usage and improving the product's lightweight and cost-effectiveness. Through the above design, the radome 10 and the cover plate 20 can maintain a more stable shape during long-term use, further improving durability and ensuring the reliability and safety of the product in various environments.

[0027] Preferably, a strip-shaped hole is provided on one side plate of the antenna radome 10 for the cable 36 to pass through. A strip-shaped rubber is detachably provided at the strip-shaped hole, and an opening is formed in the strip-shaped rubber for the cable 36 to pass through. Firstly, in terms of installation and disassembly, the detachable strip-shaped rubber makes the connection and disconnection of the cable 36 more convenient. When it is necessary to replace the cable 36 or adjust the circuit, no special tools or complicated disassembly procedures are required; the strip-shaped rubber can be easily removed, greatly saving operation time and labor costs. Secondly, from the perspective of sealing performance, the strip-shaped rubber can fit tightly against the strip-shaped hole. When the cable 36 passes through the opening in the strip-shaped rubber, the friction between the rubber and the cable 36, as well as the fit between the rubber and the opening in the strip-shaped rubber, can effectively prevent external moisture, dust, and other impurities from entering the antenna through the strip-shaped hole, avoiding damage to the internal structure of the antenna and improving the antenna's protection performance and service life. More preferably, the strip-shaped rubber is a strip-shaped rubber with an "I"-shaped cross-section.

[0028] Preferably, the lower end of the first radiating element 31 has two consecutive 90° wing-shaped bends, and the outer edge of the wing-shaped bend has a serrated structure. On the one hand, the wing-shaped bend structure increases the effective radiation length of the radiating element, thereby enhancing the antenna's radiation capability and enabling the antenna to maintain stable performance over a wider frequency band. This helps to achieve ultra-wideband support, better covering the frequency range of 700-3700MHz and being compatible with various communication systems. On the other hand, the serrated structure of the outer edge further optimizes the radiation characteristics. It can overcome the electromagnetic shielding effect that may occur with traditional smooth edges, making the radiation field more uniform and concentrated, reducing sidelobe levels, improving the antenna's directivity and gain, and allowing signals to radiate more effectively in a specific direction, enhancing communication stability and data transmission efficiency.

[0029] Preferably, the first radiating element 31, the second radiating element 32, the first coupling plate 33, the second coupling plate 34, and the third coupling plate 35 are all fixed to the radome 10 with mounting posts by screws, forming a coplanar structure. During installation and assembly, the screw fixing method greatly improves the accuracy and stability of component installation. The screw connection ensures that the relative positions of each radiating element and coupling plate are accurate, forming a regular coplanar structure, avoiding signal propagation abnormalities and uneven radiation caused by component installation deviations, thereby ensuring the stability and reliability of antenna performance. Furthermore, the coplanar structure helps optimize the antenna's electromagnetic compatibility. With each radiating element and coupling plate on the same plane, electromagnetic signals can be radiated and received more uniformly and efficiently, reducing signal reflection, scattering, and crosstalk, improving signal transmission efficiency and quality, and thus achieving optimized network performance.

[0030] Preferably, the reflector 37 is a metal reflector 37 with a flanged structure, and the surface of the reflector 37 is coated with an absorbing coating. The metal reflector 37 with the flanged structure can significantly enhance the antenna's directivity and forward gain. The flanged structure can adjust the reflection direction of electromagnetic waves, allowing more signals to radiate in the expected direction, reducing back radiation and unnecessary signal scattering, thereby greatly improving the efficiency of antenna transmission and reception, enhancing the antenna's signal strength in the target direction, and improving the quality and coverage of network communication. The surface-coated absorbing coating further enhances the antenna's performance. The absorbing coating can absorb any residual electromagnetic waves that may exist on the antenna and electromagnetic interference signals from the external environment, effectively reducing signal loss during reflection and the impact of external interference on the normal operation of the antenna. This not only ensures the purity and stability of the signal but also effectively reduces communication errors and signal interruptions caused by electromagnetic interference, ensuring that the antenna can still work stably and reliably in complex electromagnetic environments.

[0031] This utility model provides a single-polarization wall-mounted antenna, comprising a housing and an antenna body 30. The housing includes an antenna cover 10 and a cover plate 20. When the antenna cover 10 and the cover plate 20 are installed, the rubber ring 12 on the antenna cover 10 is tightened at the annular groove 21 of the cover plate 20, ensuring a tight connection between the antenna cover 10 and the cover plate 20. Furthermore, the tightening of the rubber ring 12 effectively fixes the antenna cover 10 and the cover plate 20, avoiding the cumbersome operation of requiring numerous screws or other fixing components in traditional designs. When disassembly is required, simply pull the antenna cover 10 to disengage the rubber ring 12 from the annular groove 21, easily separating the antenna cover 10 from the cover plate 20. Users can complete the installation or disassembly of the antenna without complex tools, greatly saving labor costs and time, and ensuring ease of installation and disassembly. Meanwhile, the rubber ring tightening at the annular groove 21 ensures a tight seal at the connection between the antenna radome 10 and the cover plate 20, preventing external environmental factors (such as moisture and dust) from entering the antenna and further improving its reliability and lifespan. The antenna body 30 within the housing is designed to cover a wide frequency range (700-3700MHz), providing abundant frequency band resources for selection and allocation. This allows for flexible selection and adjustment of the operating frequency band according to specific application requirements and scenarios, achieving optimized network performance. Therefore, this single-polarization wall-mounted antenna not only offers great convenience in installation and disassembly but also boasts excellent performance and reliability.

[0032] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
