Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an antenna networking device. Background Technology

[0002] Currently, operators typically operate multiple frequency bands, each employing a multiple-input multiple-output (MIMO) configuration. For example, a 4T4R configuration might be used to build a network in the low-frequency 700MHz band, while an 8T8R configuration might be used in the high-frequency 2100MHz band. When two operators share antennas, the resulting multi-frequency antenna network would need to support both 2*700MHz 4T4R and 2*2100MHz 8T8R configurations. This means integrating not only the four low-frequency arrays from each operator but also their eight high-frequency arrays. If such an integration scheme is adopted, the overall size and height of the multi-frequency antenna network would become very large, leading to a sharp increase in wind load and failing to meet the intended requirements. Summary of the Invention

[0003] Therefore, it is necessary to overcome the shortcomings of existing technologies and provide an antenna networking device that can reduce the overall size and height, reduce wind load, and be deployed in a compact space, meeting the requirements of multiple operators for antenna co-construction and sharing, and significantly reducing construction, operation and maintenance costs.

[0004] An antenna networking device includes multiple multi-frequency antennas arranged at intervals around a site in a circumferential direction; the multi-frequency antennas include:

[0005] A first antenna element, comprising a forward reflector and at least one forward radiating element connected to the forward reflector;

[0006] The second antenna unit includes a lateral reflector connected to the front reflector and arranged at an acute angle, and at least one lateral radiation unit connected to the lateral reflector. The lateral reflector is one and connected to one side of the front reflector, or the lateral reflector is two and connected to opposite sides of the front reflector respectively.

[0007] The lateral reflector of one of the multi-frequency antennas is arranged parallel to the front reflector of the other multi-frequency antenna.

[0008] In one embodiment, there are three multi-frequency antennas. When one of the multi-frequency antennas has two lateral reflectors, the two lateral reflectors of one multi-frequency antenna are respectively arranged parallel to the front reflectors of the other two multi-frequency antennas.

[0009] In one embodiment, each of the multi-frequency antennas has two lateral reflectors, and the two lateral reflectors of each multi-frequency antenna are respectively arranged parallel to the front reflectors of the other two multi-frequency antennas.

[0010] In one embodiment, the three multi-frequency antennas are arranged at equal intervals around the circumference of the site.

[0011] In one embodiment, the angle formed by the front reflector and the side reflector is set as α, where α is 55° to 65°.

[0012] In one embodiment, the forward radiation units are multiple and are arranged at intervals along the longitudinal direction of the forward reflector to form a forward radiation array;

[0013] The lateral radiation units are multiple and are arranged at intervals along the longitudinal direction of the lateral reflector to form a lateral radiation array.

[0014] In one embodiment, the forward radiation array includes two forward low-frequency arrays and at least one forward high-frequency array; the lateral radiation array includes one lateral low-frequency array and at least one lateral high-frequency array.

[0015] In one embodiment, the distance between the front reflector and the two sides is set as S1, and the distance between the lateral reflector and the two sides is set as S2, where S1>S2.

[0016] In one embodiment, the side of the forward reflector is connected to the side or middle portion of the lateral reflector.

[0017] In one embodiment, the front reflector and the side reflector are an integrated structure.

[0018] In one embodiment, the antenna networking device further includes a support frame, to which the plurality of multi-frequency antennas are connected.

[0019] In the aforementioned antenna networking device, during operation, the lateral reflector of one multi-frequency antenna and the front reflector of another multi-frequency antenna are arranged parallel to each other. That is, the lateral radiating element on the lateral reflector of one multi-frequency antenna and the front radiating element on the front reflector of another multi-frequency antenna are networked to achieve ultra-multi-frequency networking. This allows the radiating elements of the same operator to be arranged on different multi-frequency antennas, reducing the height of the antenna networking device and reducing aperture coupling, thereby improving antenna performance. In addition, since the lateral reflector and front reflector of the same multi-frequency antenna are set at an acute angle, when multiple multi-frequency antennas are arranged sequentially and spaced around the circumference of the site, the overall size is reduced, wind load is reduced, and they can be arranged in a compact space, meeting the requirements of multiple operators for antenna co-construction and sharing, and significantly reducing construction, operation, and maintenance costs.

Detailed Implementation

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] As described in the background section, the overall size of multi-frequency antennas in related technologies becomes very large after networking, leading to a sharp increase in wind load and failing to meet the preset requirements. The inventors discovered that this problem arises because the antenna arrays in related technologies are arranged side-by-side, and various decoupling methods are used to achieve miniaturization and compactness. However, when more frequency bands are integrated, such as integrating four low-frequency bands, the overall size of the multi-frequency antenna network becomes very large, resulting in a sharp increase in wind load and high construction, operation, and maintenance costs. Furthermore, without changing the overall size, related technologies cannot solve problems such as beamwidth distortion and gain reduction, making antenna miniaturization a challenge.

[0029] For the reasons mentioned above, this application provides an antenna networking device that can reduce the overall size and height, reduce wind load, and can be deployed in a compact space to meet the requirements of multiple operators for antenna co-construction and sharing, thereby significantly reducing construction, operation and maintenance costs.

[0030] See Figure 1 , Figure 4 and Figure 5, Figure 1 A schematic diagram of the structure of an antenna networking device according to an embodiment of this application is shown. Figure 4 A schematic diagram of the structure of a multi-frequency antenna 10 according to an embodiment of this application is shown. Figure 5 A schematic diagram of the structure of a multi-frequency antenna 10 according to another embodiment of this application is shown. One embodiment of this application provides an antenna networking device, which includes multiple multi-frequency antennas 10. The multiple multi-frequency antennas 10 are arranged sequentially at intervals around the circumference of the site.

[0031] Please see Figure 4 or Figure 5 The multi-frequency antenna 10 includes a first antenna element 11 and a second antenna element 12. The first antenna element 11 includes a front reflector 111 and at least one front radiating element connected to the front reflector 111. Optionally, the front radiating element includes a front low-frequency radiating element 112 and / or a front high-frequency radiating element 113; the specific configuration can be flexibly adjusted and set according to actual needs. Furthermore, the second antenna element 12 includes a lateral reflector 121 connected to the front reflector 111 and arranged at an acute angle, and at least one lateral radiating element connected to the lateral reflector 121. Optionally, the lateral radiating element includes a lateral low-frequency radiating element 122 and / or a lateral high-frequency radiating element 123; the specific configuration can be flexibly adjusted and set according to actual needs.

[0032] In addition, please see Figure 5 The lateral reflector 121 is one and connected to one side of the front reflector 111; or, please refer to Figure 4 There are two lateral reflectors 121, which are respectively connected to the opposite sides of the front reflector 111. The lateral reflector 121 of one multi-frequency antenna 10 and the front reflector 111 of the other multi-frequency antenna 10 are arranged parallel to each other.

[0033] It should be noted that the "parallel arrangement" in which the lateral reflector 121 of one multi-frequency antenna 10 and the front reflector 111 of another multi-frequency antenna 10 are arranged in parallel does not mean a strict parallel relationship in the mathematical sense. Rather, it allows for manufacturing or assembly process errors. The magnitude of such process errors is not limited here, but can be set to within 5° according to actual needs.

[0034] It should be noted that the terms "forward" in "forward reflector 111" and "lateral" in "lateral reflector 121" are only used to distinguish between reflectors at two different locations on the multi-frequency antenna 10, and should not be construed as limiting the specific orientation of the reflectors. Furthermore, depending on the arrangement of each multi-frequency antenna 10 at the site, the orientation of the forward reflector 111 of the multi-frequency antenna 10 at different locations can be different or the same; similarly, the orientation of the lateral reflector 121 of the multi-frequency antenna 10 at different locations can be different or the same.

[0035] In the aforementioned antenna networking device, during operation, the lateral reflector 121 of one multi-frequency antenna 10 and the front reflector 111 of another multi-frequency antenna 10 are arranged parallel to each other. That is, the lateral radiating element on the lateral reflector 121 of one multi-frequency antenna 10 and the front radiating element on the front reflector 111 of another multi-frequency antenna 10 are networked to achieve multi-frequency networking. This allows the radiating elements of the same operator to be arranged on different multi-frequency antennas 10, reducing the height of the antenna networking device and reducing aperture coupling, thereby improving antenna performance. In addition, since the lateral reflector 121 and the front reflector 111 of the same multi-frequency antenna 10 are arranged at an acute angle, when multiple multi-frequency antennas 10 are arranged sequentially and spaced around the circumference of the site, the overall size is reduced, wind load is reduced, and they can be arranged in a compact space, meeting the requirements of multiple operators for antenna co-construction and sharing, and significantly reducing construction, operation, and maintenance costs.

[0036] Please see Figures 1 to 3 Any one, Figure 2 and Figure 3 Schematic diagrams of antenna networking devices from two other embodiments are shown. Figure 2 and Figure 1 The difference lies in the specific structure of the multi-frequency antenna 10. Figure 3 and Figure 1 The difference also lies in the specific structure of the multi-frequency antenna 10. In one embodiment, there are three multi-frequency antennas 10. When one of the multi-frequency antennas 10 has two lateral reflectors 121, the two lateral reflectors 121 of one multi-frequency antenna 10 are respectively arranged in parallel with the front reflectors 111 of the other two multi-frequency antennas 10.

[0037] Please see Figure 1In one embodiment, each multi-frequency antenna 10 has two lateral reflectors 121, and the two lateral reflectors 121 of each multi-frequency antenna 10 are respectively arranged parallel to the front reflectors 111 of the other two multi-frequency antennas 10. In this way, the lateral radiating elements on the two lateral reflectors 121 of each multi-frequency antenna 10 are networked with the front radiating elements on the front reflectors 111 of the other two multi-frequency antennas 10 to achieve ultra-multi-frequency networking. This allows the radiating elements of the same operator to be arranged on three different multi-frequency antennas 10, reducing the height of the antenna networking device, weakening the interference between radiating elements of the same operator, reducing aperture coupling, and improving antenna performance.

[0038] Of course, in some alternative solutions, the lateral reflectors 121 of each multi-frequency antenna 10 are not limited to two, for example, see [link to relevant documentation]. Figure 2 Each multi-frequency antenna 10 has one lateral reflector 121; for example, please refer to Figure 3 One of the multi-frequency antennas 10 has one lateral reflector 121, while the other two multi-frequency antennas 10 each have two lateral reflectors 121.

[0039] Please see Figures 1 to 3 In one embodiment, three multi-frequency antennas 10 are arranged sequentially at equal intervals around the circumference of the site. This arrangement of the three multi-frequency antennas 10 is reasonable, resulting in a smaller overall size, reduced wind load, and easier placement in a compact space. Furthermore, it weakens interference between radiating elements of the same operator, reduces aperture coupling, and improves antenna performance.

[0040] Of course, as an alternative, the three multi-frequency antennas are arranged circumferentially around the site at unequal intervals.

[0041] Please see Figure 4 In one embodiment, the angle formed by the front reflector 111 and the side reflector 121 is set as α, where α is 55° to 65°.

[0042] The included angle α includes, but is not limited to, angles such as 55°, 57°, 59°, 60°, 61°, 63°, or 65°, and can also be any angle less than 55° or greater than 65°.

[0043] Please see Figure 1 and Figure 4 In one embodiment, a plurality of forward radiating elements are arranged sequentially at intervals along the longitudinal direction of the forward reflector 111 to form a forward radiating array. Furthermore, a plurality of lateral radiating elements are arranged sequentially at intervals along the longitudinal direction of the lateral reflector 121 to form a lateral radiating array.

[0044] It should be noted that the longitudinal direction of the front reflector 111 is the direction from one end of the front reflector 111 to the other end, which is also the direction of the central axis of the site. Similarly, the longitudinal direction of the lateral reflector 121 is the direction from one end of the lateral reflector 121 to the other end, which is also the direction of the central axis of the site.

[0045] Please see Figure 1 and Figure 4 In one embodiment, the forward radiation array includes two forward low-frequency arrays 112a and at least one forward high-frequency array 113a. The lateral radiation array includes a lateral low-frequency array 122a and at least one lateral high-frequency array 123a.

[0046] Each forward low-frequency array 112a includes a plurality of forward low-frequency radiating elements 112 arranged at intervals along the longitudinal direction of the forward reflector 111. Each forward high-frequency array 113a includes a plurality of forward high-frequency radiating elements 113 arranged at intervals along the longitudinal direction of the forward reflector 111. Similarly, the lateral low-frequency array 122a includes a plurality of lateral low-frequency radiating elements 122 arranged at intervals along the longitudinal direction of the lateral reflector 121. Each lateral high-frequency array 123a includes a plurality of lateral high-frequency radiating elements 123 arranged at intervals along the longitudinal direction of the lateral reflector 121.

[0047] Optionally, the number of forward high-frequency arrays 113a on each multi-frequency antenna 10 may include, but is not limited to, 1, 2, 3, 4, 5, or other numbers, which can be flexibly adjusted and set according to actual needs. Similarly, the number of lateral high-frequency arrays 123a on each multi-frequency antenna 10 may include, but is not limited to, 1, 2, 3, 4, 5, or other numbers, which can be flexibly adjusted and set according to actual needs.

[0048] Please see Figure 1 and Figure 4 In one specific embodiment, the forward radiating array includes two forward low-frequency arrays 112a and four forward high-frequency arrays 113a. Furthermore, the lateral radiating array includes one lateral low-frequency array 122a and two lateral high-frequency arrays 123a. Further, taking three multi-frequency antennas 10, each with two lateral reflectors 121, as an example, the operation of the antenna networking device will be described. Each multi-frequency antenna 10, when used in conjunction with the other two antennas at the same site, can support four low-frequency arrays and eight high-frequency arrays per sector.

[0049] Please refer to the details. Figure 1The three multi-frequency antennas 10 are respectively designated as a first multi-frequency antenna 10a, a second multi-frequency antenna 10b, and a third multi-frequency antenna 10c. The front reflector 111 of the first multi-frequency antenna 10a is designated as the first front reflector 111a, and the two lateral reflectors 121 of the first multi-frequency antenna 10a are designated as the first lateral reflector 1211 and the second lateral reflector 1212, respectively. The front reflector 111 of the second multi-frequency antenna 10b is designated as the second front reflector 111b, and the two lateral reflectors 121 of the second multi-frequency antenna 10b are designated as the third lateral reflector 1213 and the fourth lateral reflector 1214, respectively. The front reflector 111 of the third multi-frequency antenna 10c is designated as the third front reflector 111c, and the two lateral reflectors 121 of the third multi-frequency antenna 10c are designated as the fifth lateral reflector 1215 and the sixth lateral reflector 1216, respectively.

[0050] Please see Figure 1 and Figure 4 The first forward reflector 111a is parallel to the third lateral reflector 1213 and the sixth lateral reflector 1216, respectively. This means that the forward radiation arrays on the first forward reflector 111a, the third lateral reflector 1213, and the sixth reflector have the same radiation direction, thus enabling multi-frequency networking and supporting the operation of one operator. Similarly, the second forward reflector 111b is parallel to the second lateral reflector 1212 and the fifth lateral reflector 1215, respectively. This means that the forward radiation arrays on the second forward reflector 111b, the second lateral reflector 1212, and the fifth reflector have the same radiation direction, thus enabling multi-frequency networking and supporting the operation of another operator. Similarly, the third forward reflector 111c is parallel to the first lateral reflector 1211 and the fourth lateral reflector 1214, respectively. That is, the forward radiation array on the third forward reflector 111c, the lateral radiation array on the first lateral reflector 1211, and the lateral radiation array on the fourth reflector have the same radiation direction, thereby realizing multi-frequency networking and supporting the operation of another operator.

[0051] As can be seen, in addition to supporting the two low-frequency operating bands and four high-frequency operating bands in its own sector, the radiating array in each multi-frequency antenna 10 also supports one low-frequency operating band and two high-frequency operating bands in the left and right sectors. This design ensures that the two low-frequency arrays and four high-frequency arrays in the current sector do not interfere with each other, reducing aperture coupling and improving antenna performance. At the same time, it cooperates with adjacent sectors to enable the normal operation of four low-frequency arrays and eight high-frequency arrays. This achieves multiple benefits and is an effective design and networking method for co-construction and sharing of antennas.

[0052] Of course, in certain application scenarios, when the lateral reflector 121 of the multi-frequency antenna 10 is set to one, the low-frequency array integrated by each multi-frequency antenna 10 is three.

[0053] Please see Figure 5 In one embodiment, the distance between the front reflector 111 and its two sides is set to S1, which is also the width of the front reflector 111. The distance between the side reflector 121 and its two sides is set to S2, which is also the width of the side reflector 121, where S1 > S2. This ensures that the number of front radiation arrays arranged on the front reflector 111 is greater than the number of side radiation arrays arranged on the side reflector 121.

[0054] Please see Figure 1 and Figure 4 In one embodiment, the side of the front reflector 111 is connected to the side of the side reflector 121. Specifically, the side reflector 121 is obtained by bending the front reflector 111 or by integral extrusion molding, which facilitates processing and improves production efficiency.

[0055] Please see Figure 6 , Figure 6 A schematic diagram of the structure of a multi-frequency antenna 10 according to another embodiment of this application is shown. In another embodiment, the side of the front reflector 111 is connected to the middle portion of the side reflector 121. This reduces the height of the antenna networking device, which is beneficial for reducing volume and wind load, and allows for placement in a compact space.

[0056] Please see Figure 1 and Figure 4 In one embodiment, the front reflector 111 and the side reflector 121 are an integrated structure.

[0057] Optionally, the front reflector 111 and the side reflector 121 are each, for example, integrally formed metal parts, including but not limited to aluminum parts, copper parts, etc.

[0058] Optionally, the front reflector 111 and the side reflector 121 can be integrally formed by die casting, pultrusion, or welding. Of course, as some alternatives, the side reflector 121 can also be connected and fixed to the front reflector 111 by metal connectors.

[0059] Please see Figure 1 In one embodiment, the antenna networking device further includes a support frame 20. Multiple multi-frequency antennas 10 are connected to the support frame 20. Thus, the support frame 20 is positioned at the site and enables the multiple multi-frequency antennas 10 to be combined together.

[0060] Please refer to the following: Figure 1Specifically, the support frame 20 includes multiple support rods 21 and multiple support components 22. The multiple support components 22 are correspondingly connected to the multiple support rods 21, and the multiple support rods 21 are interconnected. Multiple multi-frequency antennas 10 are respectively connected to the multiple support components 22. The support components 22 are mainly used to support and install the corresponding multi-frequency antennas 10. Their specific design forms are varied and can be flexibly adjusted and selected according to actual needs, such as being set as support columns, support rods 21, support plates, etc.

[0061] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0062] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0063] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0064] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0065] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
