[0002] In modern society where mobile phones are highly used, the deployment of mobile communication antennas is crucial, which provides a physical basis for efficient communication between mobile devices and base stations. However, with the acceleration of urbanization and the increasing emphasis on the aesthetic degree of the living environment, the installation and design of mobile communication antennas are facing more and more challenges. In public areas, such as urban villages, residential communities, and commercial centers, large antennas are restricted due to their large volume and obtrusive appearance, and operators have to seek innovative solutions to reduce the impact of antennas on the surrounding environment.

[0003] Currently, for large antennas, common camouflage methods are to design them as tubular structures with ventilation functions or to ingeniously integrate them into the appearance of buildings, such as hiding them in walls, roofs, or false chimneys. However, these methods are not applicable to the antennas of small base stations, especially those installed on low masts or exterior walls of buildings, because they are relatively close to people's line of sight, and simple camouflage often fails to achieve satisfactory visual effects and is easy to be recognized. Summary of the Invention

The radio frequency lens body is at least partially in limiting fit with the inner wall of the cavity of the camouflage cover assembly. The dual-polarization radiation element is disposed between the conductive plate and the radio frequency lens body.

[0011] Further, the camouflage cover assembly is a cylindrical structure, and the radio frequency lens body is a cylindrical structure adapted to the shape of the camouflage cover assembly. The conductive plate is disposed on one of the cover plates in the axial direction of the camouflage cover assembly, or one of the cover plates in the axial direction of the camouflage cover assembly is the conductive plate. The radiation assembly further includes a plurality of conductive tubes penetrating through the radio frequency lens body, and both ends of any one of the conductive tubes extend to the two end faces of the radio frequency lens body.

[0012] Further, the radio frequency lens body is a multi-layer structure, and the radiation assembly further includes a conductive tube penetrating through the radio frequency lens body.

The adapter legs are disposed on the adapter rod. The second adapter base is an L-shaped plate base including two mutually perpendicular plates. One of the plates is connected to the camouflage cover assembly, and the other plate is disposed on the adapter platform and connected to the adapter platform.

[0014] Further, the adapter platform of the first adapter base has a first adjustment lug. The adapter assembly further includes a third adapter base, which is a plate-shaped platform with a second adjustment lug. The adapter platform of the second adapter base is connected to the plate-shaped platform.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way limits the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 4 shown, an embodiment of the present invention provides a dual-polarized antenna. The dual-polarized antenna includes a camouflage cover assembly 10, a camouflage lens 20 disposed on the camouflage cover assembly 10, a radiation assembly 30 disposed inside the camouflage cover assembly 10, and an adapter assembly 40 connected to the camouflage cover assembly 10. The adapter assembly 40 is used to set the camouflage cover assembly 10 at an installation position. The adapter assembly 40 has multiple adjustment degrees of freedom to adjust the orientations of the camouflage cover assembly 10 and the radiation assembly 30. The dual-polarized antenna is camouflaged as a camera through the camouflage cover assembly 10 and the camouflage lens 20.

[0029] In this embodiment, the dual-polarized antenna is camouflaged by the camouflage cover assembly 10 and the camouflage lens 20, so that the appearance of the dual-polarized antenna is the same as that of an ordinary surveillance camera. Even if it is set at a low position, people will recognize the dual-polarized antenna of the present invention as an ordinary surveillance camera. It has good integration with the environment and good concealment, which can improve its concealment and aesthetics in environments such as residential areas, reduce visual interference, and this camouflage method has low cost and flexible deployment. Further, through the adjustment of the camouflage cover assembly 10 by the adapter assembly 40, its movement is more like that of an ordinary camera, which is beneficial to further ensure the reliability of the camouflage. At the same time, the orientation of the radiation assembly 30 can be adjusted according to actual needs to facilitate the adjustment of the communication range and ensure the communication effect.

[0030] Specifically, the camouflage cover assembly 10 includes a cover body 11 and a cover plate 12 disposed at the opening of the cover body 11. The adapter assembly 40 is connected to the cover body 11 and / or the cover plate 12. The radiation assembly 30 is disposed in the area surrounded by the cover body 11 and the cover plate 12. The camouflage lens 20 is disposed on the cover body 11 and / or the cover plate 12.

[0031] In this embodiment, the opening of the cover body 11 facilitates the installation of the radiation assembly 30. The closed cavity formed by the combination of the cover plate 12 and the cover body 11 can protect the internal radiation assembly 30. At the same time, the camouflage effect of the antenna is further enhanced by the camouflage lens 20 on the cover plate 12. With such a setting, the dual-polarized antenna is not only similar to an ordinary camera in appearance, but also the internal components are fully protected, improving the reliability and lifespan of the dual-polarized antenna.

[0032] It is understandable that the shape of the cover body 11 can be selected according to actual conditions, and can be a cylindrical cover, a spherical cover, or other commonly used appearances of cameras.

[0033] like Figures 1 to 3 As shown, the cover body 11 is a cylindrical cover, and a cover plate 12 is respectively provided at both ends of the axial direction, the adapter assembly 40 is connected to one of the cover plates 12, and the camouflage lens 20 is installed on the other cover plate 12. The structure of the cylindrical cover body 11 is conducive to making the overall shape of the antenna more compact, and the camouflage lens 20 on the cover plate 12 simulates the appearance characteristics of the camera to improve the camouflage effect.

[0034] Preferably, there are multiple camouflage lenses 20, and the multiple camouflage lenses 20 are regularly installed on the cover plate 12. In this way, by arranging multiple camouflage lenses 20 on the cover plate 12, the appearance of a multi-lens camera is simulated, the camouflage effect of the antenna is further enhanced, and the possibility of being identified as a communication antenna is reduced. It can be understood that the specific number, size, distribution, etc. of the camouflage lenses 20 can be adaptively adjusted according to actual conditions, such as in Figure 2 and Figure 3 In the embodiment shown, there is only one camouflage lens 20, which is disposed at the center of the cover plate 12. Figure 1 In the illustrated embodiment, the camouflage lens 20 includes a main lens and a plurality of auxiliary lenses. The main lens has a radial dimension larger than that of the auxiliary lens and is disposed at the center of the cover plate 12. The plurality of auxiliary lenses are distributed around the main lens.

[0035] like Figures 1 to 3 As shown, the camouflage cover assembly 10 further includes a stopper plate 13, which is arranged at the edge of the cover plate 12 on which the camouflage lens 20 is installed, and the stopper plate 13 protrudes from the cover plate 12 in the axial direction of the cover body 11. In this way, by arranging the stopper plate 13 at the edge of the cover plate 12, the structure of the camera sun visor is imitated, which not only enhances the camouflage effect, but also protects the camouflage lens 20 from the influence of external environmental factors, so that the dual-polarized antenna not only looks the same as an ordinary camera, but also can effectively prevent direct sunlight and rain erosion, thereby extending the service life.

[0036] It is understandable that the stop plate 13 can be integrally formed or can be disassembled and installed by fasteners, and the extension length and shape of the stop plate 13 can be adaptively adjusted according to actual conditions.

[0037] like Figure 3 As shown, the radiation component 30 includes a conductive plate 31, a dual-polarization radiation element 32 and a radio frequency lens body 33. The conductive plate 31 is fixedly arranged on the inner wall of the cavity of the camouflage cover component 10. The radio frequency lens body 33 is at least partially limited and cooperated with the inner wall of the cavity of the camouflage cover component 10. The dual-polarization radiation element 32 is arranged between the conductive plate 31 and the radio frequency lens body 33.

[0038] In this embodiment, the radio frequency lens body 33 is in limit fit with the inner wall of the cover body 11, which is beneficial to ensuring the structural stability and radio frequency performance of the dual-polarized antenna. The dual-polarized radiation element 32 focuses the electromagnetic wave propagating in the radial direction parallel to the radio frequency lens body 33 into the radio frequency lens body 33. By utilizing the focusing effect of the radio frequency lens body 33 on the electromagnetic wave, the gain and directivity of the antenna are improved. At the same time, through the combination of the conductive plate 31 and the dual-polarized radiation element 32, dual-polarized communication is realized. With such a setting, while the antenna remains miniaturized, high gain and narrow beam can be achieved. Although its size is relatively small and its weight is light, the gain is relatively high, which is beneficial to ensuring the communication quality and coverage. Among them, the shape of the dual-polarized radiation element 32 is a crossed dipole.

[0039] In the embodiment as Figure 3 shown, the camouflage cover assembly 10 is a cylindrical structure, the radio frequency lens body 33 is a cylindrical structure adapted to the shape of the camouflage cover assembly 10, the conductive plate 31 is arranged on a cover plate 12 in the axial direction of the camouflage cover assembly 10, or a cover plate 12 in the axial direction of the camouflage cover assembly 10 is the conductive plate 31; the radiation assembly 30 further includes a plurality of conductive tubes 34 penetrating through the radio frequency lens body 33, and both ends of any one conductive tube 34 extend to the two end faces of the radio frequency lens body 33.

[0040] In this embodiment, the conductive tube 34 can change the dielectric constant and affect the direction of the wavelength to adjust the degree of beam aggregation. The conductive tube 34 can be penetrated into the radio frequency lens body 33 according to the design requirements, and then the overall radio frequency lens body 33 is assembled with the conductive plate 31 and the dual-polarized radiation element 32. Finally, the assembled radiation assembly 30 is installed in the camouflage cover assembly 10 to ensure the high performance and concealment of the antenna. With such a setting, by arranging the conductive tubes 34 inside the radio frequency lens body 33, a lightweight radio frequency lens is formed, which can effectively focus the electromagnetic wave while maintaining the lightweight and miniaturization of the antenna. The size and weight of the dual-polarized antenna are both reduced, but the gain and directivity are not decreased. Both ends of any one conductive tube 34 extend to the two end faces of the radio frequency lens body 33, which is beneficial to optimizing the dual-polarized radiation characteristics of the dual-polarized antenna.

[0041] Among them, the RF lens body 33 is a multi-layer structure and each layer is made of different materials. The radiation component 30 also includes a conductive tube 34 inserted into the RF lens body 33. From the outer layer of the RF lens body 33 toward the center, the compactness of the distribution of the conductive tube 34 inserted in the upper layer is less than or equal to the compactness of the distribution of the conductive tube 34 inserted in the lower layer. In this way, through the combination of the multi-layer RF lens body 33 and the conductive tube 34, a gradual focusing effect is formed, which is conducive to improving the focusing accuracy, gain and beam characteristics of the dual-polarized antenna, and can achieve a narrower beam and higher gain while maintaining the miniaturization of the dual-polarized antenna, improve the communication quality and coverage and maintain high performance. The arrangement and number of each layer of conductive tubes 34 can be adjusted according to actual RF requirements to achieve the best radiation performance. The multi-layer structure of the RF lens body 33 not only provides focusing and guiding of the RF signal, but also can adapt to different communication frequency bands and application scenarios by adjusting the layout of the conductive tube 34, which is conducive to improving the functionality and adaptability of the dual-polarized antenna.

[0042] Preferably, if Figure 3 and Figure 4 As shown, the extension directions of the plurality of conductive tubes 34 are all parallel to the RF lens body 33 .

[0043] For the distribution, Figure 3 In the illustrated embodiment, a plurality of conductive tubes 34 are embedded in the RF lens body 33 and are arranged periodically. The plurality of conductive tubes 34 in any layer are arranged equidistantly in a circle. The distribution of the conductive tubes 34 in each layer becomes more compact as one moves inward from the layer area close to the center. The compactness of the distribution of the conductive tubes 34 in each layer can be understood as follows: from the outer layer of the RF lens body 33 toward the center, the spacing between any two adjacent conductive tubes 34 in the upper layer is less than or equal to the spacing between any two adjacent conductive tubes 34 in the lower layer, wherein the spacing between the conductive tubes 34 between two adjacent layers may also gradually decrease.

[0044] Optionally, in Figure 4 In the illustrated embodiment, a plurality of conductive tubes 34 are embedded in the RF lens body 33 and are arranged periodically, the spacing between any two adjacent conductive tubes 34 is the same, and the triangle formed by the center line connecting any two adjacent three conductive tubes 34 is an equilateral triangle.

[0045] It is understandable that the number of the conductive tubes 34 , the extension direction, and the distribution of the plurality of conductive tubes 34 can be adaptively adjusted according to actual conditions, and examples are not given here one by one.

[0046] In such Figure 1 and Figure 2In the illustrated embodiment, the adapter assembly 40 includes a mounting base 41, an adapter rod 42, a first adapter base 43, and a second adapter base 44 that are sequentially connected. The mounting base 41 is detachably disposed at the mounting position through fasteners. The first adapter base 43 includes an adapter platform 431 and adapter legs 432. The adapter legs 432 are disposed on the adapter rod 42. The second adapter base 44 is an L-shaped plate base including two mutually perpendicular plates. One of the plates is connected to the camouflage cover assembly 10, and the other plate is disposed on and connected to the adapter platform 431. Such a setting makes the installation and adjustment of the dual-polarization antenna more convenient.

[0047] In the embodiment as Figure 1 shown, the adapter platform 431 of the first adapter base 43 has a first adjustment lug 433. The adapter assembly 40 further includes a third adapter base 45. The third adapter base 45 is a plate-shaped platform having a second adjustment lug 451. The adapter platform 431 of the second adapter base 44 is connected to the plate-shaped platform. The first adjustment lug 433 or the second adjustment lug 451 has an arc-shaped opening. The first adjustment lug 433 and the second adjustment lug 451 are connected in a releasable manner through an adjustment member. The position of the adjustment member in the arc-shaped opening is adjustable when relaxed, so that the camouflage cover assembly 10 makes a nodding swing.

[0048] In this embodiment, the arc-shaped opening is disposed on the second adjustment lug 451. There are two sets of symmetrically arranged first adjustment lugs 433 and second adjustment lugs 451. The fastener is a bolt member passing through the first adjustment lug 433 and the arc-shaped opening. When the bolt member is relaxed, the third adapter base 45 can be rotated. The position of the bolt member in the arc-shaped opening changes. After the third adapter base 45 is rotated to the required angle for "nodding", the bolt member is tightened to clamp the second adjustment lug 451 and the first adjustment lug 433 to prevent self-rotation. Such a setting realizes the "nodding" fine adjustment of the dual-polarization antenna in the vertical direction through the cooperation of the first adjustment lug 433 and the second adjustment lug 451, enabling it to quickly align with the communication target, which is beneficial to improving the communication effect and adapting to communication targets at different heights, enabling the dual-polarization antenna to achieve precise adjustment in the vertical direction and improving the communication quality and stability.

[0049] Preferably, the first adapter base 43 is rotatably and / or movably disposed on the adapter rod 42, and the second adapter base 44 is rotatably and / or movably disposed on the first adapter base 43. The rotation centerlines of the first adapter base 43, the second adapter base 44, and the nodding swing of the camouflage cover assembly 10 are perpendicular to each other in pairs. Among them, the relative rotation and relative movement can be realized through mechanical structures such as a clamping groove and a clamping protrusion, a releasable fastener, etc., and will not be exemplified one by one here.

[0050] In summary, the present invention provides a dual-polarized antenna, which cleverly disguises the dual-polarized antenna as the appearance of a camera through a camouflage cover assembly 10 and a camouflage lens 20. At the same time, the internal structure design ensures the high performance of the antenna. The combination of the RF lens body 33 and the conductive tube 34 enables the dual-polarized antenna to have the advantages of high gain and narrow beam while maintaining a compact size. The flexible adjustment design of the adapter assembly 40 is conducive to improving the camouflage effect of the dual-polarized antenna and the applicability of the dual-polarized antenna, thereby improving the convenience of installation and the accuracy of direction adjustment.
