Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to a suspended wire structure, a base station antenna, and a base station. Background Technology

[0002] Striplines are high-frequency transmission conductors, typically placed between two parallel ground planes. Due to their low loss and good consistency, they are widely used in passive systems, such as base station antennas and remote radio units (RRUs). With the advent of 5G, base station antennas support more and more frequency bands, leading to increasingly complex layouts and posing challenges to stripline routing and cost. In current configurations, the stripline is suspended within a closed cavity and electrically connected to the cavity, achieving grounding and signal transmission. Existing cavities for enclosing striplines are usually integrally molded, which is difficult to manufacture, costly, and restricts complex structural layouts, making stripline assembly inconvenient. Summary of the Invention

[0003] This application provides a suspended strip structure, a base station antenna, and a base station to facilitate the assembly of strips.

[0004] In a first aspect, this application provides a suspended wire structure, including a grounding cover, a grounding plate, and a wire. A first side of the grounding cover is recessed to form a receiving space, a first end of the grounding cover has a notch, and a second end of the grounding cover has an extension. The first end of the grounding plate has a connecting portion, and the first side of the grounding plate abuts against the first side of the grounding cover, with the connecting portion closing the notch. The second end of the grounding plate is connected to the extension to enclose the receiving space, thus forming a closed cavity structure with the grounding cover. The wire is disposed within the cavity structure. The second end of the grounding plate and the extension are coupled together via an intermediate member.

[0005] The technical solution provided in this application has a closed cavity structure formed by the grounding plate and the grounding cover. The wire is set in the closed cavity structure. The cavity structure is simple to form, has high manufacturing efficiency and low cost. Moreover, the internal layout of the cavity structure can be more flexible and adaptable, which facilitates the assembly of the wire. Furthermore, the second end of the grounding plate and the extension are coupled and connected through an intermediate part, which can effectively improve the intermodulation index of the wire, reduce intermodulation interference, and improve the working stability.

[0006] When specifically setting up the grounding cover, the extension is flat and parallel to the grounding plate. When the grounding plate and the grounding cover are connected, the extension can be fully aligned with the grounding plate, which improves the stability of the connection between the grounding cover and the grounding plate.

[0007] When specifically setting up the grounding plate, the connecting part is flat and perpendicular to the grounding plate. The connection between the connecting part and the grounding cover is relatively convenient, and the cavity structure formed after the grounding cover is connected to the grounding plate via the connecting part is relatively stable.

[0008] In one specific implementation scheme, the connecting part includes a first connecting support plate and a second connecting support plate connected in sequence, with the first connecting support plate and the second connecting support plate arranged at an angle; the first connecting support plate is connected to the first end of the grounding plate, and the second connecting support plate is connected to the first end of the grounding cover. The grounding cover and the grounding plate are connected by the first connecting support plate and the second connecting support plate, which makes the layout of the cavity structure more flexible and adaptable.

[0009] In one specific feasible implementation, the first connecting support plate and the second connecting support plate are arranged perpendicularly. The overall structure of the connection portion formed by the first connecting support plate and the second connecting support plate is relatively stable.

[0010] In one specific implementation scheme, the first connecting support plate is arranged perpendicularly to the grounding plate. This allows the second connecting support plate to be arranged parallel to the grounding plate. Since the grounding cover and the grounding plate can be arranged parallel to each other, the second connecting support plate can also be arranged parallel to the grounding cover, resulting in a larger connection area between the connecting part and the grounding cover, making the connection between the connecting part and the grounding cover more reliable, and thus making the cavity structure formed by the grounding plate and the grounding cover more stable.

[0011] In one specific feasible implementation, the first connecting support plate is connected to the middle of the second connecting support plate. The overall cross-sectional shape of the connecting part can be T-shaped, which facilitates the forming of the connecting part and the connection with the grounding cover. Furthermore, the connecting part and the grounding cover can have a large connection area, making the connection between the connecting part and the grounding cover more reliable, and the cavity structure formed by the grounding plate and the grounding cover is more stable.

[0012] In one specific feasible implementation, the first connecting support plate is cylindrical, with its first axial end connected to the grounding plate and its second axial end connected to the second connecting support plate. The overall shape of the connecting part approximates a screw or stud, and metal screws or studs can be used as the connecting part. The selection of the connecting part is relatively convenient and flexible, facilitating the assembly of the grounding cover and the grounding plate.

[0013] In one specific feasible implementation, the connecting part and the ground plate are integrally molded. This makes the relative position of the connecting part and the ground plate more stable.

[0014] In one specific implementation, the connecting part is integrally molded with the grounding cover. This makes the closed cavity structure formed by the grounding cover and the grounding plate more stable.

[0015] Secondly, this application provides a base station antenna, including a radiating element and a suspension strip structure as described above, the suspension strip structure being electrically connected to the radiating element.

[0016] The technical solution provided in this application allows the suspended stripline structure to be electrically connected to the radiating element of the antenna, thereby enabling the electrical connection between the antenna and the radio frequency processing unit. The suspended stripline structure has a flexible layout, strong adaptability, and facilitates the assembly of the stripline. Furthermore, it can effectively improve the intermodulation index of the stripline, reduce intermodulation interference, and make the antenna performance superior.

[0017] Thirdly, this application provides a base station, including the base station antenna as described above.

[0018] The technical solution provided in this application has superior base station antenna performance, stable base station operation, and reliable performance. Attached Figure Description

[0034] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0035] To facilitate understanding, the application scenarios of the antenna structure involved in this application will be explained first.

[0036] Figure 1 An exemplary schematic diagram of a system architecture applicable to an embodiment of this application is shown, such as... Figure 1 As shown, the system architecture may include wireless access network devices and terminals, such as, but not limited to, wireless access network devices and terminals. Figure 1The base station shown is used to enable wireless communication between the wireless access device and the terminal. This wireless access network device can be located in a base station subsystem (BBS), a UMTS terrestrial radio access network (UTRAN), or an evolved universal terrestrial radio access network (E-UTRAN), used for cell coverage of wireless signals to achieve connection between the terminal device and the wireless network radio frequency terminal. Specifically, the base station can be a base transceiver station (BTS) in a GSM or CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved NodeB (eNB or eNodeB) in an LTE system, a wireless controller in a cloud radio access network (CRAN) scenario, or it can be a relay station, access point, vehicle-mounted equipment, wearable device, a base station in a 5G network, or a base station in a future evolved PLMN network, etc., for example, a new wireless base station. This application embodiment is not limited to these types of base stations.

[0037] Figure 2 The diagram above illustrates the structure of an antenna feeding system for a base station according to one embodiment. The base station antenna feeding system typically includes an antenna 10, a mast 20, and an antenna adjustment bracket 30. The base station antenna 10 includes an radome 40, which possesses excellent electromagnetic wave penetration characteristics in terms of electrical performance and can withstand the effects of harsh external environments in terms of mechanical performance, thus protecting the antenna system from external environmental influences. The radome 40 can be mounted on the mast 20 or a tower via the antenna adjustment bracket 30 to facilitate signal reception or transmission by the antenna 10.

[0038] Additionally, the base station may include a radio frequency (RF) processing unit 50 and a signal processing unit 60. For example, the RF processing unit 50 can be used to perform frequency selection, amplification, and down-conversion processing on the signal received by the antenna 10, converting it into an intermediate frequency (IF) signal or a baseband signal and sending it to the signal processing unit 60. Alternatively, the RF processing unit 50 can be used to up-convert and amplify the IF signal from the signal processing unit 60 or the IF signal, converting it into electromagnetic waves through the antenna 10 for transmission. The signal processing unit 60 can be connected to the feed structure of the antenna 10 via the RF processing unit 50, and is used to process the IF signal or baseband signal transmitted by the RF processing unit 50.

[0039] In one possible embodiment, such as Figure 2As shown, the radio frequency processing unit 50 can be integrated with the antenna 10, and the signal processing unit 60 is located at the far end of the antenna 10. In some other embodiments, the radio frequency processing unit 50 and the signal processing unit 60 can also be located at the far end of the antenna 10 simultaneously. The radio frequency processing unit 50 and the signal processing unit 60 can be connected via a cable 70.

[0040] More specifically, please refer to the following: Figure 2 and Figure 3 , Figure 3 This is a schematic diagram of a base station antenna according to a possible embodiment of this application. Wherein, as... Figure 3 As shown, the base station antenna 10 may include radiating elements 11 and reflectors 12. The radiating element 11, also called an antenna element, is the basic structural unit of the antenna array, effectively radiating or receiving antenna signals. Different radiating elements 11 in the antenna 10 may have the same or different frequencies. The reflector 12, also called a base plate, antenna panel, or metal reflective surface, reflects and focuses the antenna signal onto the receiving point. The radiating elements 11 are typically placed on one side of the reflector 12. This not only greatly enhances the signal reception or transmission capability of the antenna 10 but also blocks and shields interference from other electromagnetic waves originating from the back of the reflector 12 (in this application, the back of the reflector 12 refers to the side opposite to where the radiating elements 11 are located) from affecting the antenna signal reception.

[0041] In the antenna 10 of the base station, the radiating element 11 is connected to the feed network 3. The feed network 3 is typically composed of controlled impedance transmission lines. The feed network 3 can feed signals to the radiating element 11 with a certain amplitude and phase, or send the received signals to the signal processing unit 60 of the base station with a certain amplitude and phase. In addition, the feed network 3 can achieve different radiation beam directions through the transmission component 31, or connect to the calibration network 32 to obtain the calibration signals required by the system. The feed network 3 may include a phase shifter 33 to change the maximum direction of antenna signal radiation. The feed network 3 may also include modules for extending performance, such as a combiner 34 (which can be used to combine signals of different frequencies into one for transmission through the antenna 10; or, in reverse, can be used to split the signals received by the antenna 10 into multiple paths according to different frequencies for transmission to the signal processing unit 50 for processing) and a filter 35 (used to filter out interference signals).

[0042] The suspended stripline structure provided in this application can be adapted to a base station antenna, for example, it can constitute a passive device of a base station antenna for signal transmission. Exemplarily, one terminal of the suspended stripline structure can be electrically connected to the radiating element of the antenna, and the other terminal can be electrically connected to the radio frequency processing unit, thereby realizing the electrical connection between the antenna and the radio frequency processing unit. Currently, the stripline is suspended in a closed cavity and electrically connected to the cavity, achieving grounding through the cavity, thus realizing signal transmission. However, the cavity is integrally molded, which is difficult to mold and makes it difficult to achieve complex structural layouts, hindering the assembly of the stripline.

[0043] Based on this, embodiments of this application provide a suspension belt structure to facilitate the assembly of belts.

[0044] Figure 4 This diagram shows a front cross-sectional view of the suspension strip structure provided in an embodiment of this application. Figure 5 This diagram shows a top cross-sectional view of the suspension strip structure provided in an embodiment of this application. Figure 6 A schematic diagram of the grounding cover with a suspended wire structure provided in an embodiment of this application is shown. Figure 6 For the ground cover Figure 4 (Structural diagram viewed from the first direction). Please refer to the diagram as well. Figure 4 , Figure 5 and Figure 6 The suspended cable structure provided in this application embodiment may include a ground cover 100 and a grounding plate 200, with the first side of the grounding plate 200 abutting against the first side of the ground cover 100.

[0045] The first side edge of the ground cover 100 Figure 4 The grounding cover 100 is recessed in the first direction to form a receiving space 130. That is, the side of the grounding cover 100 facing the grounding plate 200 is recessed in the direction away from the grounding plate 200 to form a receiving space 130. The first end of the grounding cover 100 may have a notch 110. The grounding cover 100 can be understood as a groove-shaped structure with a notch 110 on the side wall. Furthermore, the second end of the grounding cover 100 may have an extension 120.

[0046] The grounding plate 200 may have a connecting portion 210 at its first end. When the grounding plate 200 is mated with the grounding cover 100, the connecting portion 210 can close the notch 110. The second end of the grounding plate 200 can connect with the extension portion 120, thereby closing the receiving space 130 and forming a closed cavity structure after the grounding plate 200 and the grounding cover 100 are mated. The connecting portion 210 may be adapted to the shape and size of the notch 110, or the size of the connecting portion 210 may be larger than the size of the notch 110 to close the notch 110. When the grounding cover 100 is mated with the grounding plate 200, the connecting portion 210 may be located inside or outside the grounding cover 100.

[0047] In practical applications, both the grounding cover 100 and the grounding plate 200 can be made of conductive materials, such as metal, or they can be made of non-metallic materials and plated with a metal layer, so that both the grounding cover 100 and the grounding plate 200 can conduct electricity. After the grounding cover 100 and the grounding plate 200 are connected, they can be electrically connected. The grounding plate 200 can be grounded, and since the grounding cover 100 is electrically connected to the grounding plate 200, the grounding cover 100 is also grounded. The live wire 400 can be set in the closed cavity structure formed by the connection between the grounding plate 200 and the grounding cover 100. The live wire 400 can be electrically connected to the grounding plate 200, for example, it can be electrically connected to the connecting part 210, or it can be electrically connected to the grounding cover 100, so that the live wire 400 is grounded, and thus the live wire 400 can transmit signals within the closed cavity structure. The wire 400 can be directly connected to the grounding plate 200 or the grounding cover 100 to achieve electrical connection, or it can be connected to the grounding plate 200 or the grounding cover 100 through a conductive connector to achieve electrical connection.

[0048] In the suspended wire structure of this application embodiment, the grounding plate 200 and the grounding cover 100 are connected to form a closed cavity structure, and the wire 400 is disposed in the closed cavity structure. The cavity structure is simple to form, has high manufacturing efficiency, low cost, and the internal layout of the cavity structure can be more flexible and adaptable, which facilitates the assembly of the wire 400.

[0049] In a specific implementation, the second end of the ground plane 200 and the extension 120 can be coupled together via the intermediate component 300. When two or more signals of different frequencies act on a nonlinear circuit, they will modulate each other, generating a new frequency signal output. If this frequency happens to fall within the receiver's operating channel bandwidth, it constitutes interference to the receiver; this interference is called intermodulation interference. The intermediate component 300 ensures that the second end of the ground plane 200 and the extension 120 are not in direct contact, but are electrically connected via coupling. This ensures that at least a portion of the grounding of the enclosed cavity structure is coupled to ground, effectively improving the intermodulation performance of the stripline 400, reducing intermodulation interference, and thus improving the antenna's operational stability. In a specific implementation, the intermediate component 300 can be a non-conductive film structure; for example, the intermediate component 300 can be a plastic film, polyimide film, etc. It is understood that the connection portion 210 and the grounding cover 100 can also be coupled together, meaning that the connection portion 210 and the grounding cover 100 do not need to be in direct contact, and a gap exists between them.

[0050] As one possible embodiment, the extension 120 can be made of a conductive material, such as a metal, or it can be made of a non-metallic material and plated with a metal layer. The extension 120 can be flat and can be located opposite the notch 110 on the grounding cover 100. When the grounding plate 200 and the grounding cover 100 are mated, the extension 120 can mate with the grounding plate 200, and the extension 120 can be parallel to the grounding plate 200. In a specific implementation, the extension 120 can be integrally formed with the grounding cover 100, or it can be fixedly connected to the grounding cover 100 by welding or other methods.

[0051] As one possible embodiment, since the connecting portion 210 serves both to close the notch 110 on the grounding cover 100 and to electrically connect the grounding plate 200 and the grounding cover 100, in specific implementations, the connecting portion 210 can be made of a conductive material, such as a metal material, or it can be made of a non-metallic material and plated with a metal layer. When the grounding plate 200 and the grounding cover 100 are mated, the grounding plate 200 and the grounding cover 100 can be electrically connected through the connecting portion 210. Specifically, the connecting portion 210 can be a flat plate structure. The connecting portion 210 can be set at an angle to the grounding plate 200; for example, the connecting portion 210 can be set perpendicular to the grounding plate 200. Figure 4 The example shown illustrates a case where the connecting part 210 is perpendicular to the grounding plate 200. Alternatively, the connecting part 210 may be positioned at other angles to the grounding plate 200, allowing for flexible configuration based on the dimensions of the grounding plate 200 and the grounding cover 100, as well as the actual docking conditions.

[0052] In specific implementations, the connecting part 210 can be fixedly and electrically connected to the grounding plate 200 by welding or other methods, or the connecting part 210 can be integrally formed with the grounding plate 200. The connecting part 210 can be detachably connected to the grounding cover 100 by metal screws or other conductive connectors to achieve an electrical connection between the connecting part 210 and the grounding cover 100; or the connecting part 210 can be fixedly connected to the grounding cover 100 by welding or other methods.

[0053] Figure 7 Another structural schematic diagram of the suspension wire structure provided in an embodiment of this application is shown. (Reference) Figure 7 In some possible embodiments, to make the closed cavity structure formed by the mating of the grounding plate 200 and the grounding cover 100 more stable, the connecting part 210 and the grounding cover 100 can be integrally formed. It should be noted that this situation and the situation where the connecting part 210 and the grounding plate 200 are integrally formed can coexist, that is, the grounding plate 200, the connecting part 210, and the grounding cover 100 can be integrally formed. Figure 7 The example illustrates a case where the grounding plate 200, the connecting part 210, and the grounding cover 100 are integrally formed.

[0054] Figure 8 Another structural schematic diagram of the suspension wire structure provided in an embodiment of this application is shown. (Reference) Figure 8 In one possible embodiment, the connecting portion may include a first connecting support plate 211 and a second connecting support plate 212 connected in sequence. Both the first connecting support plate 211 and the second connecting support plate 212 may be made of conductive material, such as metal, or they may be made of non-metallic material and plated with a metal layer. The first connecting support plate 211 and the second connecting support plate 212 may be arranged at an angle; for example, they may be arranged perpendicular to each other. Figure 8 The example illustrates the case where the first connecting plate 211 is perpendicular to the second connecting plate 212. In practice, the first connecting plate 211 and the second connecting plate 212 can be integrally formed, or they can be fixedly connected and electrically connected by welding or other methods.

[0055] In a specific implementation, one end of the first connecting support plate 211 can be connected to the first end of the grounding plate 200, the other end of the first connecting support plate 211 can be connected to one end of the second connecting support plate 212, and the other end of the second connecting support plate 212 can be connected to the first end of the grounding cover 100. In actual implementation, the first connecting support plate 211 can be set perpendicular to the grounding plate 200, so the second connecting support plate 212 can be set parallel to the grounding plate 200. Since the grounding cover 100 and the grounding plate 200 can be set parallel to each other, the second connecting support plate 212 can also be set parallel to the grounding cover 100. At this time, the notch of the grounding cover 100 can be mainly closed by the first connecting support plate 211, and the second connecting support plate 212 can extend into the grounding cover 100. The side of the second connecting support plate 212 away from the first connecting support plate 211 can be connected to the grounding cover 100, so that the connection area between the connecting part and the grounding cover 100 is larger, the connection between the connecting part and the grounding cover 100 is more reliable, and the closed cavity structure formed by the connection between the grounding plate 200 and the grounding cover 100 is more stable. More specifically, the first connecting support plate 211 and the grounding plate 200 can be fixedly and electrically connected by welding or other methods. Alternatively, the first connecting support plate 211 and the grounding plate 200 can be detachably and electrically connected by metal screws or other conductive connectors. Similarly, the second connecting support plate 212 and the grounding cover 100 can be detachably and electrically connected by metal screws or other conductive connectors. It is understood that the second connecting support plate 212 and the grounding cover 100 can also be coupled together. In this case, the second connecting support plate 212 and the grounding cover 100 may not be in direct contact, but rather have a gap, and the screws or other connectors connecting the second connecting support plate 212 and the grounding cover 100 are non-conductive connectors.

[0056] In specific implementation, the connecting part can be integrally formed with the grounding plate 200, that is, the first connecting support plate 211 and the second connecting support plate 212 can be integrally formed with the grounding plate 200. The connecting part can also be integrally formed with the grounding cover 100. It can be understood that this situation can coexist with the situation where the connecting part is integrally formed with the grounding plate 200, that is, the connecting part can be integrally formed with the grounding plate 200 and the grounding cover 100. In other words, the first connecting support plate 211, the second connecting support plate 212, the grounding plate 200 and the grounding cover 100 can be integrally formed.

[0057] Figure 9 Another structural schematic diagram of the suspension wire structure provided in an embodiment of this application is shown. (Reference) Figure 9In one possible embodiment, the first connecting support plate 211 can be connected to the middle of the second connecting support plate 212. The first connecting support plate 211 and the second connecting support plate 212 can be arranged perpendicular to each other, that is, the overall cross-sectional shape of the connecting part along the first direction can be T-shaped. In this case, the first connecting support plate 211 can be arranged perpendicular to the grounding plate 200, so that the second connecting support plate 212 can be arranged parallel to the grounding cover 100. Similarly, the connecting part has a large area for connecting with the grounding cover 100, and the connection between the connecting part and the grounding cover 100 is more reliable, making the closed cavity structure formed by the mating of the grounding plate 200 and the grounding cover 100 more stable.

[0058] When the overall cross-sectional shape of the connecting part is T-shaped, the first connecting support plate 211 can be cylindrical. In this case, the first end of the first connecting support plate 211 along the axial direction can be connected to the grounding plate 200, and the second end of the first connecting support plate 211 along the axial direction can be connected to the second connecting support plate 212. It can be understood that the overall shape of the connecting part is similar to a screw or stud. In actual implementation, metal screws or studs can be used as the connecting part to close the gap and to connect the grounding plate 200 and the grounding cover 100. Similarly, the second connecting support plate 212 and the grounding cover 100 can be detachably connected and electrically connected by metal screws or other conductive connectors. Alternatively, the second connecting support plate 212 and the grounding cover 100 can also be coupled together. In this case, the second connecting support plate 212 and the grounding cover 100 do not need to be in direct contact, and there is a gap. The screws or other connectors connecting the second connecting support plate 212 and the grounding cover 100 are non-conductive connectors.

[0059] In specific implementations, the first connecting support plate 211 can be cylindrical, elliptical cylindrical, plate-shaped, or other shapes, and can be flexibly configured according to actual needs and processing difficulty. Similarly, when the first connecting support plate 211 is connected to the middle of the second connecting support plate 212, the connecting part can also be integrally formed with the grounding plate 200; that is, the first connecting support plate 211 and the second connecting support plate 212 can be integrally formed with the grounding plate 200. The connecting part can also be integrally formed with the grounding cover 100. Similarly, this situation can coexist with the situation where the connecting part is integrally formed with the grounding plate 200; that is, the connecting part can be integrally formed with the grounding plate 200 and the grounding cover 100. In other words, the first connecting support plate 211, the second connecting support plate 212, the grounding plate 200, and the grounding cover 100 can all be integrally formed.

[0060] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
