[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411749620.5, filed on November 29, 2024, entitled "Coupled Connection Structure, Transmission Component, Antenna, Communication Equipment and Communication System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication equipment technology, and in particular to a coupling connection structure, transmission component, antenna, communication equipment and communication system. Background Technology

[0004] Base station antennas are fundamental to current mobile communications and occupy a crucial position. With the evolution of base station antennas and the trend towards modular integration of radio frequency devices, signal connections are needed between the inner and outer conductors of different components. Currently, the most common method is to use metal connections between two inner conductors and between two outer conductors, which offers the widest matching bandwidth. However, metal connections are prone to passive intermodulation (PIM) distortion, placing high demands on practical applications and manufacturing processes. Summary of the Invention

[0005] This application provides a coupling connection structure, transmission component, antenna, communication device and communication system, which helps to reduce PIM risk, improve VSWR performance, realize small-size coupling in radio frequency circuits, and improve antenna integration.

[0006] Firstly, this application provides a coupling connection structure. This coupling connection structure includes a first connection portion and a second connection portion. The first connection portion includes a first coupling end, a second coupling end, and a first connector, with the first connector electrically connecting the first coupling end and the second coupling end. The first coupling end is used for coupling connection with a first part of a first device, and the second coupling end is coupled connection with a second part of a second device, thereby achieving coupling connection between the first and second parts. The second connection portion includes a third coupling end, a fourth coupling end, and a second connector, with the second connector electrically connecting the third coupling end and the fourth coupling end. The third coupling end is used for coupling connection with a third part of the first device, and the fourth coupling end is coupled connection with a fourth part of the second device, thereby achieving coupling connection between the third and fourth parts. The first connection portion and the second connection portion are electrically connected via an inductor. This solution can achieve coupling connection between the first and second devices, which helps reduce PIM risk. A capacitor-inductor-capacitor (CLC) filter circuit can be formed, thereby improving the standing wave ratio. By rationally designing the inductance between the first and second connection parts, the matching can be adjusted, thereby reducing the capacitance of the coupled connection. This reduces the area of ​​the coupled connection at both ends, achieving small-size coupling in the radio frequency circuit, which is beneficial to improving the integration of the antenna.

[0007] In the specific technical solution, the first connecting part and the second connecting part are electrically connected by a third connecting member, which is an equivalent inductor. In this solution, the inductor structure is relatively simple, which helps to simplify the structure of the coupling connection, and the manufacturing process is also relatively simple.

[0008] Alternatively, in a specific technical solution, the first connecting part may be connected to a fourth connecting member, the second connecting member may be connected to a fifth connecting member, the fourth connecting member and the fifth connecting member may be coupled together, and the fourth connecting member and the fifth connecting member may be equivalent inductors.

[0009] In practical implementation, the coupling connection structure can be formed on a dielectric substrate. For example, the first coupling end and the third coupling end are disposed on the same layer, and the second coupling end and the fourth coupling end are disposed on the same layer. A first insulating layer is provided between the first coupling end and the second coupling end to separate the first coupling end and the second coupling end, and to separate the third coupling end and the fourth coupling end. A second insulating layer is provided on the side of the first coupling end facing away from the second coupling end, and a third insulating layer is provided on the side of the second coupling end facing away from the first coupling end. This protects the first coupling end, the second coupling end, the third coupling end, and the fourth coupling end, and facilitates maintaining the coupling distance. The first connector and the second connector are conductive holes that penetrate the first insulating layer. This design facilitates reducing the volume of the coupling connection structure and simplifies its fabrication.

[0010] In one specific technical solution, the first coupling end includes a first arc ring, the second coupling end includes a second arc ring, the third coupling end includes a third arc ring, and the fourth coupling end includes a fourth arc ring. The central axes of the first and third arc rings coincide, as do the central axes of the second and fourth arc rings. This solution is advantageous for using a hinged connection to link the coupling structure. Thus, even when the first transmission component and the coupling structure rotate relative to each other in the hinged state, a reliable coupling connection can be maintained, and the coupling area remains constant. The connection between the second transmission component and the coupling structure is similar and will not be described in detail here. This solution ensures that the coupling capacitance generated between the first transmission component and the coupling structure remains constant, thereby improving the signal transmission effect and stability of the transmission component.

[0011] Secondly, this application also provides a transmission component. The transmission component includes a first transmission element, a second transmission element, and the coupling connection structure provided in the first aspect. The first transmission element and the second transmission element are connected via the coupling connection structure. Specifically, the first transmission element includes a first inner conductor and a first outer conductor, and the second transmission element includes a second inner conductor and a second outer conductor. The first inner conductor is coupled to a first coupling end, and the second inner conductor is coupled to a second coupling end. Thus, the first inner conductor and the second inner conductor are connected. The first outer conductor is coupled to a third coupling end, and the second outer conductor is coupled to a fourth coupling end, thus, the first outer conductor and the second outer conductor are coupled together. This solution helps reduce PIM risk. A capacitor-inductor-capacitor (CLC) filter circuit can be formed, thereby improving the standing wave ratio. By rationally designing the inductance between the first and second connection parts, matching can be adjusted, thereby reducing the capacitance and thus reducing the area of ​​the coupling connection at both ends, achieving small-size coupling in the radio frequency circuit, which is beneficial for improving the antenna integration.

[0012] In the specific technical solution, the first transmission element is hinged to the first end of the coupling connection structure, with the first coupling end and the third coupling end located at the first end. Since the first transmission element and the coupling connection structure are coupled, no fixed installation is required; the hinged connection enhances the flexibility between the first transmission element and the coupling connection structure. Similarly, the second transmission element is hinged to the second end of the coupling connection structure, with the second coupling end and the fourth coupling end located at the second end. This also improves the flexibility between the second transmission element and the coupling connection structure.

[0013] Thirdly, this application also provides an antenna. The antenna includes a radiator and a transmission component provided in the first aspect above. The transmission component is electrically connected to the radiator and is used to feed the radiator. This helps reduce PIM risk, improve VSWR performance, achieve small-size coupling in RF circuits, and improve antenna integration.

[0014] Fourthly, this application also provides a communication device. This communication device includes a baseband processing unit and an antenna as provided in the third aspect, the baseband processing unit being connected to a feed network in the antenna. The antenna can be either an active or passive antenna. For example, when the antenna is an active antenna, it may include a radio frequency (RF) processing unit, and the baseband processing unit can be connected to the feed network through the RF processing unit. Alternatively, when the antenna is a passive antenna, the baseband processing unit can be directly connected to the feed network. This is beneficial for reducing PIM risk, improving VSWR performance, achieving small-size coupling in the RF circuit, and improving the antenna's integration density.

[0015] The radio frequency (RF) processing unit can be used to perform frequency selection, amplification, and down-conversion processing on the signals received by the antenna's vibrator. Alternatively, the RF processing unit can be used to transmit RF signals to the antenna, thereby enabling the antenna to perform signal transmission and reception functions.

[0016] The baseband processing unit is connected to the radio frequency (RF) processing unit. The RF processing unit can be used to perform frequency selection, amplification, and down-conversion processing on the signal received by the antenna, and convert it into an intermediate frequency (IF) signal or a baseband signal to be sent to the baseband processing unit. Alternatively, the RF processing unit can be used to up-convert and amplify the IF signal emitted by the baseband processing unit, convert it into a wireless signal through the antenna, and send it out.

[0017] Fifthly, this application also provides a communication system, which includes a core network device and the aforementioned communication device, wherein the communication device is communicatively connected to the core network device to realize wireless communication function.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0032] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise.

[0033] References to “an embodiment” or “a specific embodiment” as used in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. The terms “comprising,” “including,” “having,” and variations thereof mean “including, but not limited to,” unless otherwise specifically emphasized.

[0034] To facilitate understanding of the coupling connection structure, transmission component, antenna, communication device, and communication system provided in the embodiments of this application, their application scenarios will be introduced first below.

[0035] Figure 1 is a schematic diagram of an application scenario of the communication system in this application embodiment. As shown in Figure 1, the application scenario may include communication equipment and terminals. Wireless communication can be realized between the communication equipment and terminals. The communication equipment may 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), and is used to provide cell coverage of wireless signals to enable communication between the terminal equipment and the wireless network. Specifically, the communication equipment can be a base transceiver station (BTS) in a Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) system, a Node B (NB) in a Wideband Code Division Multiple Access (WCDMA) system, an Evolutionary Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a radio controller in a Cloud Radio Access Network (CRAN) scenario. Alternatively, the communication equipment can also be a relay station, access point, vehicle-mounted equipment, wearable device, or a g node (gNodeB or gNB) in a New Radio (NR) system, or a base station in a future evolved network, etc., and the embodiments in this application are not limited to these.

[0036] In this application, the antenna can also be used in access network equipment, sometimes also called access nodes. Access network equipment has wireless transceiver capabilities for communicating with terminals. Access network equipment includes, but is not limited to, base stations, evolved NodeBs (eNodeBs), transmission reception points (TRPs) in the aforementioned communication systems, next-generation NodeBs (gNBs) in 5G mobile communication systems, future communication networks, access network equipment or modules of access network equipment in Open RAN (ORAN) systems, base stations in future mobile communication systems, or access nodes in WiFi systems. Access network equipment can also be modules or units capable of implementing some of the functions of a base station. For example, access network equipment can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), as described below. In the ORAN system, CU can also be called O-CU, DU can be called open (O)-DU, CU-CP can be called O-CU-CP, CU-UP can be called O-CUP-UP, and RU can be called O-RU. Access network equipment can be macro base stations, micro base stations, or indoor stations, relay nodes, donor nodes, or wireless controllers in cloud radio access network (CRAN) scenarios. Optionally, access network equipment can also be servers, wearable devices, or vehicle-mounted equipment. For example, in vehicle-to-everything (V2X) technology, the access network equipment can be a roadside unit (RSU). Multiple access network devices in a communication system can be base stations of the same type or different types. Base stations can communicate with terminals directly or via relay stations. Terminals can communicate with multiple base stations using different access technologies.

[0037] Understandably, the terminal communicating with the communication equipment or system in this application can be customer premises equipment (CPE). This CPE can be, for example, a network device that converts mobile cellular signals, such as those from LTE, Wideband Code Division Multiple Access (W-CDMA), or Global System for Mobile Communication (GSM) systems, into wireless fidelity (Wi-Fi) or wireless local area networks (WLAN) signals. In some embodiments, the CPE can be a fixed wireless access (FAW) device, where FAW is a technology combining fixed-line and wireless communication to provide broadband access services to users. Alternatively, the terminal can also be a lampsite, which can be used, for example, to introduce base station signals indoors, solving the problem of indoor blind spot coverage.

[0038] Figure 2 is a schematic diagram of a communication device in an embodiment of this application. As shown in Figure 2, the communication device provided in this embodiment can be understood as a base station, which includes a base station antenna feeder system. In practical applications, the base station antenna feeder system mainly includes an antenna 01, a feeder line 02, and a grounding device 03, etc. The antenna 01 is generally fixed on the mounting bracket 04 by a fixing bracket 05.

[0039] Additionally, the communication device may include a radio frequency (RF) processing unit 06 and a baseband processing unit 07. For example, the RF processing unit 06 can be used to perform frequency selection, amplification, and down-conversion processing on the signal received by the antenna 01, converting it into an intermediate frequency (IF) signal or a baseband signal and sending it to the baseband processing unit 07. Alternatively, the RF processing unit 06 can be used to up-convert and amplify the IF signal emitted by the baseband processing unit 07, converting it into a wireless signal through the antenna 01 and transmitting it. The baseband processing unit 07 can be connected to the feed network 013 of the antenna 01 via the RF processing unit 06. In some embodiments, the RF processing unit 06 may also be referred to as a remote radio unit (RRU), and the baseband processing unit 07 may also be referred to as a baseband unit (BBU).

[0040] As shown in Figure 2, in one possible embodiment, the radio frequency processing unit 06 can be integrated with the antenna 01, while the baseband processing unit 07 is located at the far end of the antenna 01. The radio frequency processing unit 06 and the baseband processing unit 07 can be connected via a feed line 02. In another embodiment, the radio frequency processing unit 06 and the baseband processing unit 07 can both be located at the far end of the antenna 01.

[0041] Figure 3 is a schematic diagram of an antenna structure in an embodiment of this application. Referring to Figures 2 and 3, the antenna 01 used in a communication device may further include an radome 011, a ground plane 012, a feed network 013, and a radiator 014. The main function of the feed network 013 is to feed signals to the radiator 014 with a certain amplitude and phase, or to transmit the wireless signals received by the radiator 014 to the baseband processing unit 07 of the base station with a certain amplitude and phase. It is understood that, in specific implementations, the feed network 013 may include at least one of the following devices: a phase shifter, a combiner, a transmission or calibration network, or a filter. This application does not limit the components, type, or functions that the feed network 013 can achieve.

[0042] Of course, the antenna 01 described above can also be applied to various other types of communication devices. This application does not limit the application scenarios of the antenna 01.

[0043] It should be noted that, in practical applications, the mounting bracket 04, fixing bracket 05, and other equipment can be provided by the site provider. The antenna 01, radio frequency processing unit 06, and baseband processing unit 07 in the base station can be provided by the base station manufacturer. The base station in this embodiment may also exclude the fixing bracket 05.

[0044] Regarding the radome 011, in terms of electrical performance, the radome 011 has good electromagnetic wave penetration, thus not affecting the normal transmission and reception of electromagnetic waves between the radiator 014 and the outside world. In terms of mechanical performance, the radome 011 has good stress resistance and oxidation resistance, thus being able to withstand the corrosion of harsh external environments.

[0045] The radiator 014, also known as a radiating element, dipole, or radiating unit, is a basic structural element of an antenna, capable of effectively transmitting or receiving electromagnetic waves. In practical applications, the radiator 014 can be categorized into single-pole and dual-pole types. The type of radiator 014 can be appropriately selected based on actual requirements during configuration.

[0046] Figure 4 is a schematic diagram of an antenna structure in an embodiment of this application. As shown in Figure 4, the antenna 01 in this embodiment includes a radiator 014 and a transmission component 015. The transmission component 015 is electrically connected to the radiator 014 and is used to feed power to the radiator 014. In a specific embodiment, the transmission component 015 can connect the radiator 014 and the feed network 013. For example, the transmission component 015 can be a feed line.

[0047] The transmission component 015 in this embodiment can be applied to a radio frequency circuit. The transmission component 015 is used to transmit radio frequency signals to power the radiator 014. Figure 5 is a schematic diagram of one structure of the transmission component in this embodiment. As shown in Figure 5, in one embodiment, the transmission component 015 includes a first transmission element 1, a second transmission element 2, and a coupling connection structure 3. The first transmission element 1 includes a first inner conductor 11 and a first outer conductor 12. The second transmission element 2 includes a second inner conductor 21 and a second outer conductor 22. The first transmission element 1 and the second transmission element 2 are coupled together through the coupling connection structure 3. Specifically, the first inner conductor 11 of the first transmission element 1 and the second inner conductor 21 of the second transmission element 2 are coupled together through the coupling connection structure 3; the first outer conductor 12 of the first transmission element 1 and the second outer conductor 22 of the second transmission element 2 are coupled together through the coupling connection structure 3.

[0048] Figure 6 is a schematic diagram of one structure of the transmission component in an embodiment of this application, and Figure 7 is a schematic diagram of another structure of the transmission component in an embodiment of this application. As shown in Figures 6 and 7, in one embodiment, the coupling connection structure 3 includes a first connection portion 31 and a second connection portion 32. The first connection portion 31 includes a first coupling end 311, a second coupling end 312, and a first connector 313, with the first connector 313 electrically connecting the first coupling end 311 and the second coupling end 312. In a specific embodiment, by electrically connecting the first coupling end 311 and the second coupling end 312 through the first connector 313, the first connection portion 31 can be considered as a conductor, with the first coupling end 311 and the second coupling end 312 also being a part of the first connection portion 31. Similarly, the second connection portion 32 includes a third coupling end 321, a fourth coupling end 322, and a second connector 323, with the second connector 323 electrically connecting the third coupling end 321 and the fourth coupling end 322. In a specific embodiment, the second connector 323 electrically connects the third coupling end 321 and the fourth coupling end 322. The second connector 32 can be regarded as a conductor, the third coupling end 321 is a part of the second connector 32, and the fourth coupling end 322 is also a part of the second connector 32.

[0049] The first inner conductor 11 of the first transmission element 1 is coupled to the first coupling end 311, and the second inner conductor 21 of the second transmission element 2 is coupled to the second coupling end 312, thereby coupling the first inner conductor 11 and the second inner conductor 21. The first outer conductor 12 of the first transmission element 1 is coupled to the third coupling end 321, and the second outer conductor 22 of the second transmission element 2 is coupled to the fourth coupling end 322, thereby coupling the first outer conductor 12 and the second outer conductor 22.

[0050] It is understood that the coupling connection in this embodiment refers to a capacitive coupling connection. Specifically, the two structures in the coupling connection are arranged face-to-face and spaced apart to form capacitive coupling. For example, the first inner conductor 11 is coupled to the first coupling end 311. It is understood that the first inner conductor 11 includes a first surface, and the first coupling end 311 includes a second surface. The first surface and the second surface are opposite to each other and spaced apart, so that the first inner conductor 11 and the first coupling end 311 form capacitive coupling, thereby realizing the coupling connection between the first inner conductor 11 and the first coupling end 311. The other coupling connections are similar and will not be described in detail here.

[0051] Figure 8 is an equivalent circuit diagram of the transmission component in an embodiment of this application. As shown in Figure 8, the first connecting part 31 and the second connecting part 32 are respectively connected to the first transmission element 1 and the second transmission element 2 through coupling connections, and the first connecting part 31 and the second connecting part 32 are connected by an inductor. In this embodiment of the application, both ends of the coupling connection structure 3 are connected to the devices at both ends through coupling connections, which helps to reduce PIM risk. The first connecting part 31 and the second connecting part 32 are connected by an inductor, thereby forming a capacitor-inductor-capacitor (CLC) filter circuit, thereby improving the standing wave ratio. In this scheme, by reasonably designing the inductor between the first connecting part 31 and the second connecting part 32, the matching can be adjusted, thereby reducing the capacitance, which can reduce the area of ​​the coupling connection at both ends, realizing small-size coupling in the radio frequency circuit, which is beneficial to improving the integration of antenna 01.

[0052] There are various options for the structure that implements the inductive connection between the first connecting part 31 and the second connecting part 32. It can be a circuit or module with inductive function, such as a directly connected inductor. Alternatively, the connection structure between the first connecting part 31 and the second connecting part 32 can be considered equivalent to an inductor in the circuit. For example, in the embodiment shown in Figure 6, the first connecting part 31 and the second connecting part 32 can be electrically connected by a third connector 33, which can be considered an equivalent inductor. The inductor structure in this embodiment is relatively simple, which helps to simplify the structure of the coupling connection structure 3, and the manufacturing process is also relatively simple. For example, the third connector 33 can be a trace or a conductive hole.

[0053] In the embodiment shown in Figure 7, the first connecting portion 31 can be connected to a fourth connecting member 314, and the second connecting member 323 can be connected to a fifth connecting member 324. The fourth connecting member 314 and the fifth connecting member 324 are coupled together, meaning they do not need to be in contact, and they are equivalent inductors. In a specific embodiment, the fourth connecting member 314 and the fifth connecting member 324 are at least partially opposite to each other to form a coupled connection.

[0054] Specifically, the electrical length of the fourth connector 314 can be made the same as the electrical length of the fifth connector 324.

[0055] The transmission component 015 in this embodiment can be applied to a radio frequency circuit. The transmission component 015 is used to transmit radio frequency signals. In addition to power supply, the transmission component 015 can be applied in any scenario where radio frequency signals need to be transmitted.

[0056] Figure 9 is a schematic diagram of a transmission component in an embodiment of this application. As shown in Figure 9, in one embodiment, the coupling connection structure 3 may further include a dielectric plate 34, which can be a rigid dielectric plate or a flexible dielectric plate. For example, the dielectric plate 34 may include a first insulating layer 341, a second insulating layer 342, and a third insulating layer 343. The first coupling end 311 and the third coupling end 321 are disposed on the same layer, and the second coupling end 312 and the fourth coupling end 322 are disposed on the same layer. A first insulating layer 341 is provided between the first coupling end 311 and the second coupling end 312, and the third coupling end 321 and the fourth coupling end 322 are disposed on opposite sides of the first insulating layer 341. The first insulating layer 341 can separate the first coupling end 311 and the second coupling end 312, and separate the third coupling end 321 and the fourth coupling end 322. Furthermore, a second insulating layer 342 is disposed on the side of the first coupling end 311 opposite to the second coupling end 312, thereby protecting the first coupling end 311 and the third coupling end 321, and facilitating support for the first coupling end 311 and the first inner conductor 11, creating a certain gap between the first coupling end 311 and the first inner conductor 11. It also supports the third coupling end 321 and the first outer conductor 12, creating a certain gap between the third coupling end 321 and the first outer conductor 12. Additionally, a third insulating layer 343 is disposed on the side of the second coupling end 312 opposite to the first coupling end 311. The third insulating layer 343 may include the second coupling end 312 and the fourth coupling end 322. The function of the third insulating layer 343 is the same as that of the second insulating layer 342, and will not be elaborated here. This design facilitates a reduction in the volume of the coupling connection structure 3 and simplifies the fabrication of the coupling connection structure.

[0057] In this embodiment, the first connector 313 and the second connector 323 are conductive holes penetrating the first insulating layer 341, respectively. For ease of description, it is assumed that the first coupling end 311 and the second coupling end 312 are electrically connected through the first conductive hole 315 penetrating the first insulating layer 341, and the third coupling end 321 and the fourth coupling end 322 are electrically connected through the second conductive hole 325 penetrating the first insulating layer 341.

[0058] Figure 10 is a schematic diagram of one embodiment of the coupling connection structure 3 in this application. As shown in Figures 9 and 10, there are multiple options for implementing the inductive connection between the first connection portion 31 and the second connection portion 32. For example, the first coupling end 311 can be connected to a first metal layer 331, which is disposed on the same layer as the first coupling end 311; the fourth coupling end 322 can be connected to a second metal layer 332, which is disposed on the same layer as the fourth coupling end 322. Specifically, the first metal layer 331 and the second metal layer 332 are disposed on opposite sides of the first insulating layer 341, and the first metal layer 331 and the second metal layer 332 are electrically connected through a third conductive hole 333, thereby realizing the electrical connection between the first connection portion 31 and the second connection portion 32.

[0059] Figure 11 is a schematic diagram of one embodiment of the coupling connection structure 3 in this application. As shown in Figure 11, in one embodiment, the first coupling end 311 may be connected to a first metal layer 331, which is disposed in the same layer as the first coupling end 311; the fourth coupling end 322 may be connected to a second metal layer 332, which is disposed in the same layer as the fourth coupling end 322. Specifically, the first metal layer 331 and the second metal layer 332 are disposed on opposite sides of the first insulating layer 341 (not shown in the figure), and the first metal layer 331 and the second metal layer 332 are opposite each other along the thickness direction. Specifically, the orthographic projection of the first metal layer 331 on the plane where the first coupling end 311 is located and the orthographic projection of the second metal layer 332 on the plane where the first coupling end 311 is located may at least partially overlap, thereby making the first metal layer 331 and the second metal layer 332 coupled together.

[0060] As shown in Figure 5, in one embodiment, the first coupling end 311, the first connector 313, and the second coupling end 312 are an integral structure, the third coupling end 321, the fourth coupling end 322, and the second connector 323 are an integral structure, and the first connector 313 and the second connector 323 are electrically connected through the third connector 33.

[0061] Figure 12 is a partially enlarged schematic diagram of a transmission component in an embodiment of this application. Referring to Figures 5 and 12, in one embodiment, the first transmission element 1 is hinged to the first end of the coupling connection structure 3. Specifically, the first transmission element 1 and the coupling connection structure 3 are connected via a first rotating shaft 35. The first coupling end 311 and the third coupling end 321 are located at the first end. The first inner conductor 11 of the first transmission element 1 is coupled to the first coupling end 311, and the first outer conductor 12 is coupled to the third coupling end 321. Since the first transmission element 1 and the coupling connection structure 3 are coupled, no fixed setting is required, and the first end of the first transmission element 1 and the coupling connection structure 3 can be hinged to improve the flexibility between the first transmission element 1 and the coupling connection structure 3. Similarly, the second transmission element 2 is hinged to the second end of the coupling connection structure 3. Specifically, the second transmission element 2 and the coupling connection structure 3 are connected via a second rotating shaft. The second coupling end 312 and the fourth coupling end 322 are located at the second end, which can improve the flexibility between the second transmission element 2 and the coupling connection structure 3. This scheme makes the transmission component 015 more flexible and facilitates its deployment.

[0062] In the embodiments of this application, the transmission component 015 may include one coupling connection structure 3, or two or more coupling connection structures 3, which are not limited or described in detail in this application.

[0063] In a specific embodiment, please refer to Figures 5 and 10. In one embodiment, the first coupling end 311 includes a first arc ring, the second coupling end 312 includes a second arc ring, the third coupling end 321 includes a third arc ring, and the fourth coupling end 322 includes a fourth arc ring. The central axes of the first and third arc rings coincide, as do the central axes of the second and fourth arc rings. In this embodiment, even when the first transmission element 1 and the coupling connection structure 3 are hinged at their first ends, relative rotation between them can maintain a reliable coupling connection and help keep the coupling area constant. The connection between the second transmission element 2 and the coupling connection structure 3 is similar and will not be described in detail here. This embodiment allows the coupling capacitance generated between the first transmission element 1 and the coupling connection structure 3 to remain unchanged, thereby improving the signal transmission effect and stability of the transmission component 015.

[0064] In one specific embodiment, as shown in FIG10, at least one of the first coupling end 311, the second coupling end 312, the third coupling end 321 and the fourth coupling end 322 may be a ring.

[0065] 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. Therefore, the scope of protection of this application should be determined by the scope of the claims.
