[0002] With the rapid development of mobile communications, in order to provide higher quality network services, operators have proposed the concept of full and seamless coverage, and are continuously increasing investment in network construction. Among these efforts, spotlight-type aesthetic antennas, which do not affect the appearance of the environment and do not cause resistance from residents, have been widely used. However, the installation of spotlight antennas requires angle adjustment, necessitating the use of third-party mounting brackets. This results in a lack of flexibility in existing spotlight antenna installation methods, making it difficult to achieve quick adjustment and disassembly, especially in multi-band, high-precision applications where flexibility and adjustability are particularly important. Therefore, it is necessary to provide single-polarized spotlight antennas that not only simplify the installation process and improve the flexibility of angle adjustment, but also enable quick disassembly, thereby improving product performance and user experience.

Detailed Implementation
[0019] 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.
[0020] See Figure 1 as well as Figure 2This embodiment provides a single-polarization spotlight antenna, including an antenna body 10 and a fixing device 20 connected to the antenna body 10. The fixing device 20 is used to install and fix the antenna body 10. The fixing device 20 includes a mounting side plate 41 for fixing to a wall or other place, and an antenna mounting plate 40 rotatably connected to the mounting side plate 41. One end of the mounting side plate 41 is hinged and rotatably connected to one end of the antenna mounting plate 40. An adjusting rod 42 is provided in the middle of the other end of the antenna mounting plate 40 and the mounting side plate 41. One end of the adjusting rod 42 is rotatably connected to the antenna mounting plate 40, and the other end of the adjusting rod 42 is connected to the mounting side plate 41. The antenna mounting plate 40 is provided with a quick-release device 30 for quick assembly and disassembly of the antenna body 10.
[0021] As a preferred embodiment, the adjusting rod 42 is an electrically operated telescopic rod. This application uses the electrically operated telescopic rod to drive the mounting side plate 41 and the antenna mounting plate 40, thereby adjusting the installation angle of the antenna body 10. The electric drive characteristic of the telescopic rod makes it easy to operate; during installation or when angle adjustment is needed, ground operators can easily adjust it using control buttons or a remote control, avoiding the difficulty of manual adjustment at height, greatly reducing operational difficulty and labor costs. Furthermore, it possesses high precision, with millimeter-level or even finer length adjustment capabilities, ensuring accurate antenna angle adjustment under complex signal coverage requirements, such as in the construction of 5G base stations in urban centers or the establishment of high-precision communication networks. In addition, the electric telescopic rod has a fast response speed, enabling adjustment to be completed in a short time, meeting the needs of scenarios requiring real-time antenna direction adjustment, such as outdoor live broadcast communication support and emergency rescue communication network construction.
[0022] Preferably, the quick-release device 30 includes an abutment plate 31, a limiting member 32 is provided in the middle of the abutment plate 31, and a plurality of retractable columns 33 are provided around the periphery of the abutment plate 31. The antenna body 10 is provided with a quick-release member 34 adapted to the limiting member 32. Further, the limiting member 32 includes a base and a limiting part provided on the outer periphery of the top of the base. The limiting part includes a limiting part inlet 35 and a limiting groove 36 connected to the limiting part inlet 35. During installation, the operator holds the antenna body 10 and aligns the quick-release member 34 on the antenna body 10 with the limiting member 32 on the abutment plate 31. The quick-release member 34 is slowly inserted into the limiting part inlet 35. During this process, the shell of the antenna body 10 applies a certain pressure to the retractable columns 33 around the abutment plate 31, causing the retractable columns 33 to be gradually compressed and contracted. Due to the elastic characteristics of the retractable columns 33, they store a certain amount of elastic potential energy. Continue pushing the antenna body 10 so that the quick-release piece 34 smoothly enters along the limiting part inlet 35 and rotates a certain angle before entering the limiting groove 36. Once the quick-release piece 34 is fully inside the limiting groove 36, the previously compressed retractable column 33 quickly rebounds under the action of elastic potential energy. During the rebound, the retractable column 33 applies a force evenly distributed away from the abutment plate 31 towards the antenna body 10. This force pushing away from the abutment plate 31 pushes the antenna body 10, causing the quick-release piece 34 to tightly engage with the limiting groove 36, thereby ensuring a tight installation of the antenna body 10 and the antenna mounting plate 40. Because the retractable column 33 has multiple evenly distributed forces, the antenna body 10 can be evenly subjected to pressure, thus ensuring the stability and tightness of the installation and preventing loosening or displacement. It should be noted that the quick-release piece 34 in this application can be four L-shaped inserts arranged in a ring, which can be inserted into the limiting groove 36.
[0023] Preferably, each side of the mounting side plate 41 has a sliding plate 47, and each sliding plate 47 is provided with an arc-shaped groove 48. A sliding plate 49 is provided on the antenna mounting plate 40 at a position corresponding to the mounting side plate 41, and the sliding plate 49 is slidably connected to the arc-shaped groove 48. The sliding plate 47 and the sliding plate 49 effectively prevent the mounting side plate 41 and the antenna mounting plate 40 from tilting in the left and right directions, thus effectively improving the stability of the installation. Specifically, during antenna operation, it may be affected by external factors such as wind and vibration. The cooperation of the sliding plate 47 and the sliding plate 49 enhances the structural strength of the overall device, reduces the occurrence of antenna angle shift, component wear or damage due to tilting, ensures that the antenna is always in a stable working state, thereby improving signal transmission quality and system reliability, and extending the service life of the device.
[0024] Preferably, the sliding plate 47 is provided with angle scale lines 50 on its side. During installation, the angle scale lines 50 provide operators with a clear reference standard, allowing them to accurately adjust the antenna mounting plate 40 to the required angle without relying on experience or complex measuring tools, thus improving installation accuracy and signal transmission performance. In subsequent maintenance and adjustments, it can help maintenance personnel quickly locate the current angle and make precise adjustments, saving time and ensuring operational status.
[0025] Preferably, the antenna body 10 includes an antenna cover made of a wave-transparent material, comprising a detachably connected front shell and a rear shell; a reflector disposed inside the antenna cover; a dual-polarized radiating element fixed inside the antenna cover, comprising a low-frequency vibrator group consisting of two symmetrically arranged low-frequency vibrators forming a horizontal array; a mid-high frequency vibrator group consisting of at least three mid-high frequency vibrators arranged sequentially forming a horizontal array, wherein the first and last mid-high frequency vibrators are nested inside the radiating arms of the low-frequency vibrators; an ultra-high frequency vibrator group consisting of 2 to 6 ultra-high frequency vibrators arranged horizontally and located below the low-frequency vibrator group and the mid-high frequency vibrator group; and a power divider disposed on the back of the reflector, electrically connected to the low-frequency vibrator group, the mid-high frequency vibrator group, and the ultra-high frequency vibrator group via a microstrip line to achieve multi-band combined feeding. By combining a symmetrical horizontal array layout of low-frequency oscillators with a nested structure of mid-to-high-frequency oscillators, and a horizontally stacked arrangement of ultra-high-frequency oscillators, full-band coverage of 700-3700MHz is achieved, significantly improving multi-network compatibility. The oscillators employ a space reuse and vertical stacking design, completing multi-band combined power supply within a compact space. This reduces antenna size to accommodate spotlight shapes and optimizes the radiation pattern through reflectors, enhancing vertical beamwidth and significantly improving signal penetration and edge leakage resistance in high-rise, narrow-coverage scenarios. Meanwhile, the detachable antenna housing and modular oscillator layout facilitate maintenance and debugging, reducing deployment costs.
[0026] Furthermore, the number of ultra-high frequency (UHF) vibrator groups is 3-4, and their radiators employ a stepped metal sheet structure to extend the high-frequency bandwidth. By setting the number of UHF vibrator groups to 3-4 and using a stepped metal sheet structure as the radiator, the high-frequency bandwidth is significantly extended, improving the signal coverage and transmission efficiency of the 5G band (3300-3700MHz). The stepped structure optimizes the radiation characteristics of high-frequency signals, enhances the antenna's gain and directivity at high frequencies, and reduces signal distortion and interference. This not only improves the stability and reliability of the antenna in complex electromagnetic environments but also ensures high-efficiency performance when multiple frequency bands are combined and fed, making it particularly suitable for the high-speed data transmission requirements of 5G networks.
[0027] Furthermore, the radiating arm of the low-frequency oscillator is provided with an L-shaped bending structure at its end. By extending the current path, the low-frequency resonant bandwidth (e.g., 700-960MHz) is effectively expanded, enhancing the signal penetration in complex building environments. At the same time, the capacitive coupling effect generated by the L-shaped bending can suppress high-frequency harmonic interference, improve the isolation when multiple frequency bands coexist, and ensure electromagnetic compatibility between the low-frequency and mid-to-high-frequency oscillators.
[0028] The single-polarized spotlight antenna provided by this utility model features a fixing device 20 comprising a mounting side plate 41 and an antenna mounting plate 40. One end of the mounting side plate 41 and the antenna mounting plate 40 are hinged and rotatably connected, while the other end is connected via an adjusting rod 42. This allows for flexible adjustment of the relative angle between the antenna mounting plate 40 and the mounting side plate 41, thereby enabling adjustment of the antenna body 10's angle during installation. The quick-release device 30 on the antenna mounting plate 40 allows for rapid assembly and disassembly of the antenna body 10, improving installation and disassembly efficiency, greatly simplifying the installation process, and enhancing operational convenience. Especially in multi-band, high-precision applications, this flexibility and convenience significantly improve product performance and optimize user experience. Furthermore, the antenna body 10 of this application covers 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 needs and scenarios, achieving optimized network performance. Therefore, this single-polarized spotlight antenna enables flexible adjustment of the antenna angle and quick assembly and disassembly of the antenna body 10, simplifying the installation process and improving convenience; the 700-3700MHz wideband coverage provides abundant frequency resources, which can be flexibly adjusted according to needs, providing a high-performance solution for mobile communication.
[0029] 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.
