[0001] Cross-reference to related applications
[0002] This application claims priority to Chinese Patent Application No. 202510386567.5, filed on March 27, 2025, entitled "Feeding Network, Antenna, Communication Equipment and Communication System", the entire contents of which are incorporated herein by reference; and Chinese Patent Application No. 202510477793.4, filed on April 15, 2025, entitled "Feeding Network, 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 technology, and in particular to a power supply network, antenna, communication equipment and communication system. Background Technology
[0004] Base station antennas achieve bidirectional signal transmission between the main equipment and the radiating element through a feed network. The feed network typically includes a transmission structure and multiple functional components. The functional components are used to regulate the signal, while the transmission structure is the crucial carrier for signal transmission. Therefore, the design of the transmission structure directly affects the transmission performance of the feed network. A common transmission structure design involves placing the strip within a plastic frame, using the frame to restrict the position and shape of the strip. This type of transmission structure is often complex, and the plastic frame requires a large amount of adhesive during molding, resulting in higher material costs and relatively greater transmission losses. Summary of the Invention
[0005] This application provides a power supply network, antenna, communication equipment, and communication system to reduce transmission loss and cost of the power supply network.
[0006] In a first aspect, this application provides a power supply network, which includes a metal floor, transmission lines, and a plurality of fasteners. The fasteners are disposed on the metal floor and protrude from at least one surface of the metal floor along its thickness direction. The transmission lines are connected to the portions of the fasteners protruding from the surface of the metal floor, and the transmission lines are spaced apart from the surface of the metal base plate, such that the transmission lines are suspended from the metal floor.
[0007] In this application, multiple fasteners fix the transmission line at multiple points relative to the metal floor, thus allowing the transmission line to be reliably suspended on the surface of the metal floor. Furthermore, compared to a single, integral plastic frame, the discretely arranged fasteners effectively reduce the amount of plastic material used while ensuring reliable support and connection of the transmission line. This reduces the cost of the plastic material and the weight of the power supply network, and also lowers the transmission line's transmission loss.
[0008] In some implementations, the fasteners can be formed on the metal floor using an injection molding process. This not only eliminates the need for assembly between the fasteners and the metal floor, but also avoids assembly tolerances between the fasteners and the metal floor, thereby reducing the difficulty of aligning the transmission lines with the metal floor in the subsequent assembly and improving the overall structural accuracy of the power supply network.
[0009] In some implementations, multiple fasteners may comprise multiple identical fastener groups arranged sequentially. That is, the number of fasteners in each fastener group, the shape of fasteners in the same arrangement, the order of the fasteners, and the spacing between any two fasteners in each fastener group are the same as the spacing between any two fasteners in the same arrangement in all other fastener groups. With this design, during the fabrication of the power supply network, the fasteners in each fastener group can be molded in one step, while multiple fastener groups can be injection molded sequentially using the same mold. This significantly simplifies the fabrication process for multiple fasteners, facilitating automated mass production of the power supply network and improving its production efficiency.
[0010] In some implementations, the spacing between any two adjacent fasteners in the fastener group can be the same, thereby providing a relatively uniform supporting force for the transmission line. In other implementations, at least two of the spacings between any two adjacent fasteners in the fastener group are different, to make the fastener layout more flexible and improve the adaptability of the fastener position to the shape of the transmission line.
[0011] In some implementations, the multiple fasteners include multiple fastener groups arranged sequentially, with fasteners in each group disposed at at least a portion of the multiple arrangement positions on the metal floor. At least one arrangement position corresponding to at least one fastener group is not provided with a fastener, while in the multiple arrangement positions corresponding to the remaining fastener groups, the same arrangement position as the at least one arrangement position is provided with a fastener, and the fasteners in the multiple arrangement positions corresponding to the remaining fastener groups are identical. In this solution, each fastener group can also be injection molded sequentially using the same mold, thereby simplifying the processing of multiple fasteners. Furthermore, by rationally designing the number of fasteners in each fastener group, the layout flexibility of the fasteners can be effectively improved, and the number of fasteners can be reduced while ensuring reliable fixation of the transmission line to the metal floor, thereby reducing the amount of plastic material used and lowering the material cost of the power supply network.
[0012] In some implementations, the spacing between any two adjacent fastener groups can be the same. When the transmission line has a regularly varying shape, multiple fastener groups arranged at equal intervals can more reliably secure the transmission line to the metal floor. In other implementations, at least two of the spacings between any two adjacent fastener groups are different to improve the flexibility of fastener layout, thereby meeting the fastening requirements of transmission lines with diverse shapes.
[0013] In some implementations, the fastener may include a sub-fastener that can be inserted into the metal floor. This allows multiple fasteners to have the same shape, facilitating mass production of multiple fasteners and simplifying the manufacturing process of the power supply network.
[0014] For example, the metal floor has an opening corresponding to the position of each fastener, and the sub-fasteners of each fastener can be fixed to the metal floor by being inserted into the corresponding opening.
[0015] In some implementations, the fastener may include multiple sub-fasteners, each of which is inserted into a metal floor, and the multiple fasteners can be connected into a single structure by connecting ribs. The multiple sub-fasteners and their connecting ribs can be integrally injection molded, which not only facilitates the processing of individual fasteners but also significantly simplifies the overall processing and assembly of the power supply network, thus improving the production efficiency of the power supply network.
[0016] In some embodiments, the sub-fixing member may include a first portion and a second portion protruding from a surface of the metal floor along its thickness direction, the second portion being connected to the side of the first portion away from the metal floor, the second portion being used to connect the transmission line, and the first portion being used to support the transmission line, thereby enabling the transmission line to be reliably suspended on the surface of the metal floor.
[0017] For example, the transmission line is provided with through holes corresponding to the sub-fixing members, and the second part of the sub-fixing member can be inserted into the through hole.
[0018] In addition, the sub-fixing member may also include a third part, which is connected to the end of the first part away from the second part. The third part can be inserted into the opening in the metal floor, thereby fixing the sub-fixing member relative to the metal floor.
[0019] In some embodiments, the sub-fixing member includes a first protrusion and a second protrusion protruding from both sides of the metal ground plane along its thickness direction. The first and second protrusions each include a first portion and a second portion, respectively. The second portion of the first protrusion is connected to the side of the first portion away from the metal ground plane, and the second portion of the second protrusion is connected to the side of the first portion of the second protrusion away from the metal ground plane. The second portion of the first protrusion is used to connect to a first sub-transmission line of the transmission line, and the second portion of the second protrusion is used to connect to a second sub-transmission line of the transmission line. In this solution, the two sub-transmission lines of the transmission line can be used to transmit radio frequency signals with different polarization directions. By distributing the two sub-transmission lines on both sides of the metal ground plane, the space on both sides of the metal ground plane can be fully utilized, allowing the feed network to match the signal transmission requirements of the dual-polarized radiating element with a relatively small size, thus contributing to the miniaturization design of the antenna.
[0020] In some implementations, the end of the second part of the sub-fixing member can be formed into a rivet head by hot riveting, and the transmission line can be crimped between the rivet head and the first part to achieve a fixed connection between the transmission line and the sub-fixing member.
[0021] In some other embodiments, the end of the second part of the sub-fixing member is provided with a snap fastener, which can be used to snap and fix the sub-fixing member to the transmission line.
[0022] For example, the snap fastener can be an inverted L-shaped structure, having a limiting surface facing the metal floor, which can press the transmission line between its limiting surface and the end face of the first portion. Alternatively, the snap fastener includes one or more elastic arms disposed along the periphery of the second portion, with a first end of the elastic arm connected to the end of the second portion, and a second end of the elastic arm elastically deformable in a direction toward or away from the second portion along the radial direction of the second portion, which can press the elastic arm between the second end of the elastic arm and the end face of the first portion.
[0023] In another embodiment, the second part is provided with a fixing hole and a rivet, the rivet having an end of the second part riveted to the fixing hole, thereby crimping the transmission line between the rivet and the end face of the first part.
[0024] In some implementations, the fastener is made of a dielectric material. Dielectric materials have relatively high dielectric strength, thus ensuring reliable insulation between the transmission line and the metal ground plane. Exemplarily, the fastener may be made of plastic.
[0025] In some implementations, the transmission line is a metal strip. For example, the transmission line can be a sheet metal strip with shape retention capabilities, allowing it to be smoothly suspended from the surface of a metal floor under the support of fasteners.
[0026] In some implementations, the feed network may further include a dielectric substrate, which may be mounted on the side of the transmission line facing the metal ground plane, and the dielectric substrate is connected to a portion of the fixture protruding from the surface of the metal ground plane along its thickness direction. In this solution, the fixture and the transmission line can be relatively decoupled, which not only reduces the difficulty of positioning the fixture, but also makes it less restrictive to the size and winding matching of the transmission line, thereby helping to reduce the difficulty of connecting the transmission line to the radiating element of the antenna.
[0027] In some implementations, the power supply network may also include a phase shifter, which can be connected to the transmission line, thereby simplifying the structural design of the power supply network and improving its integration.
[0028] In other implementations, the power supply network may also include a phase shifter, at least a portion of which may be formed by transmission lines. This can effectively simplify the assembly and positioning of the power supply network and improve its production efficiency.
[0029] In some implementations, the power supply network may also include a dielectric block, which may be disposed between the transmission line and the metal ground plane. The dielectric block allows for the regulation of the transmission parameters of the transmission line, thereby adjusting the phase and impedance of the signal transmitted by the transmission line and altering the radiation performance of the radiating elements connected to the transmission line.
[0030] In some implementations, the power supply network further includes a metal side plate disposed on at least one side of the metal floor along its width, the metal side plate extending along the length of the metal floor. The metal side plate can protect the transmission lines, reducing signal radiation loss in the transmission lines, while not affecting the exposure of the metal floor's surface used for mounting the transmission lines, thus allowing for greater assembly flexibility of the metal floor.
[0031] In some implementations, the transmission line includes a first sub-transmission line and a second sub-transmission line, and the metal side plates can be respectively provided beyond the two sides of the metal floor along the thickness direction, thereby achieving protection for the first sub-transmission line and the second sub-transmission line on both sides.
[0032] In some implementations, the transmission line may include multiple stubs. The feed network also includes a metal partition disposed on at least one surface of the metal floor along its thickness direction, the metal partition extending along the length direction of the metal floor, and the metal partition dividing the surface of the metal floor along its thickness direction into at least two regions. Each of the at least two regions is provided with a fixing member, and the fixing member in each region can be used to connect at least one stub of the transmission line. Therefore, the metal partition can isolate different stubs of the transmission line, thereby reducing the mutual interference between signals transmitted in the various stubs of the transmission line and improving the signal transmission quality.
[0033] In some implementations, the transmission line includes a first sub-transmission line and a second sub-transmission line. Metal partitions can be provided on both sides of the metal floor. The metal partition on one side of the metal floor can isolate the various branches of the first sub-transmission line, and the metal partition on the other side of the metal floor can isolate the various branches of the second sub-transmission line.
[0034] In some implementations, the power supply network may also include a metal housing for housing the metal floor, transmission lines and multiple fasteners, and the metal housing is insulated from the metal floor and transmission lines respectively. The metal housing can effectively reduce the radiation loss of signals in the transmission lines, thereby improving the signal transmission efficiency of the power supply network.
[0035] Secondly, this application also provides an antenna, which includes a radiating element and a feed network as described in any of the embodiments of the first aspect, wherein the feed network is connected to the radiating element. Based on the lightweight and low-loss design of the feed network, the overall weight of the antenna is relatively small, and the communication performance of the antenna can also be improved.
[0036] Thirdly, this application also provides a communication device, which includes a radio frequency processing unit and the antenna described in the second aspect above. By applying the antenna described above, the communication performance of the communication device can be effectively improved.
[0037] In some implementations, the radio frequency processing unit is combined with the antenna, or the radio frequency processing unit can be integrated with the antenna, thus forming an active antenna unit.
[0038] Fourthly, this application also provides a communication system, including core network equipment and the communication device described in any of the embodiments of the third aspect above. The communication device is communicatively connected to the core network equipment to realize wireless communication functionality. In the communication system provided by this application, by equipping it with the aforementioned communication device, the signal transmission and reception performance of the communication system can be effectively improved.

Detailed Implementation
[0079] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this application are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this application. The accompanying drawings of the embodiments of this application are only for illustrating relative positional relationships and do not represent actual scale.
[0080] It should be noted that specific details are set forth in the following description to facilitate understanding of this application. However, the embodiments of this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the embodiments of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0081] The feeding network provided in this application embodiment can be applied to an antenna to transmit signals. The antenna can then be applied to communication equipment such as base stations, radar, or terminal devices to enable the communication equipment to perform wireless communication functions.
[0082] Figure 1 illustrates an application scenario of a communication device. Referring to Figure 1, the communication device is applied in a communication system, enabling wireless communication with terminals within the system. The communication 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 enable communication between terminal devices and the wireless network. Specifically, the communication device 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 device may be a relay station, access point, vehicle-mounted equipment, wearable device, or g node (gNodeB or gNB) in a new radio (NR) system, or a base station in a future evolved network, etc., and the embodiments of this application are not limited to this.
[0083] Additionally, antennas can also be used in access network equipment, sometimes also called access nodes. Access network equipment has wireless transceiver capabilities for communication 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 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 also be called open (O)-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CUP-UP, and RU can also be called O-RU. The access network equipment can be a macro base station, micro base station, indoor station, relay node, donor node, or a radio controller in a cloud radio access network (CRAN) scenario. Optionally, the access network equipment can also be a server, wearable device, or vehicle-mounted equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). Multiple access network equipment in the 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.
[0084] Figure 2 is a schematic diagram of a communication system provided in an embodiment of this application. Referring to Figure 2, the communication system includes communication equipment and core network equipment. The communication equipment is communicatively connected to the terminal. The core network equipment includes, but is not limited to, mobility management equipment, serving gateways, and wireless gateways.
[0085] In the embodiment shown in Figure 2, the communication device 1000 is used as a base station for illustration. In the following embodiments, the base station and the communication device 1000 use the same reference numerals. The base station 1000 includes an antenna 100 and a radio frequency processing unit 200, which is connected to the antenna 100. When the base station 1000 receives a signal, the radio frequency processing unit 200 can be used to perform frequency selection, amplification, and down-conversion processing on the signal received by the antenna 100, and convert it into an intermediate frequency signal or a baseband signal. When the base station 1000 transmits a signal, the radio frequency processing unit 200 is used to up-convert and amplify the intermediate frequency signal or baseband signal, and then convert it into a wireless signal through the antenna 100 for transmission. In some embodiments, the radio frequency processing unit 200 may also be referred to as a remote radio unit (RRU).
[0086] In some embodiments, the base station 1000 further includes a baseband processing unit 300, which is connected to the radio frequency processing unit 200. When the base station 1000 receives a signal, the baseband processing unit 300 receives the intermediate frequency signal or baseband signal converted by the radio frequency processing unit 200 and demodulates it to recover a digital signal; when the base station 1000 transmits a signal, the baseband processing unit 300 modulates the digital signal into an intermediate frequency signal or a baseband signal and then sends it to the radio frequency processing unit 200. In some embodiments, the baseband processing unit 300 may also be referred to as a baseband unit (BBU).
[0087] The baseband processing unit 300 and the radio frequency (RF) processing unit 200 can be connected via a cable 400. In one embodiment, the RF processing unit 200 and the baseband processing unit 300 may be located at the distal end of the antenna 100. In another embodiment, the RF processing unit 200 may be integrated with the antenna 100, and the baseband processing unit 300 may be located at the distal end of the antenna 100. In this example, the RF processing unit 200 and the antenna 100 may be collectively referred to as an active antenna unit (AAU).
[0088] In some embodiments, the base station further includes a grounding device 500, a mounting component 600, a pole 700, etc. The grounding device 500 is connected to the cable 400, the mounting component 600 can mount the antenna 100 on the pole 700, and the mounting component 600 can adjust the downtilt angle of the antenna 100 to adjust the signal coverage range of the antenna 100 to a certain extent.
[0089] Figure 3 is a schematic diagram of the structure of an antenna 100 provided in an embodiment of this application. Referring to Figure 3, in this embodiment, the antenna 100 includes a feed network 110 and one or more radiating elements 120, with the feed network 110 connected to the radiating elements 120. The feed network 110 is also connected to a radio frequency processing unit, and can transmit radio frequency signals received from the radio frequency processing unit to the radiating elements 120 according to a certain amplitude and phase, or transmit wireless signals received by the radiating elements 120 to the radio frequency processing unit according to a certain amplitude and phase.
[0090] The radiating element 120, also known as an antenna element, is the basic structural unit of the antenna 100, capable of effectively transmitting or receiving electromagnetic waves. The radiating element 120 can be classified into single-polarized and dual-polarized types. In practical applications, the type of radiating element 120 can be appropriately selected according to actual needs.
[0091] In some embodiments, the antenna 100 further includes a reflector 130, radiating elements 120 can be arrayed on one side surface of the reflector 130, and a feed network 110 can be disposed on the other side surface of the reflector 130. The reflector 130 is provided with a clearance hole 1301, which extends from one side surface of the reflector 130 to the other side surface. The feed network 110 can be connected to the corresponding radiating element 120 through the clearance hole 1301.
[0092] The reflector 130 can also be called a floor, antenna panel, or reflective surface. When the antenna 100 receives a signal, the reflector 130 can reflect and focus the antenna signal onto the receiving point. When the antenna 100 transmits a signal, the signal can be sent to the reflector 130 and reflected back by the reflector 130.
[0093] In some embodiments, the antenna 100 further includes a radome 140, which can be used to house the aforementioned feed network 110, radiating element 120, reflector 130, and other components. In other embodiments, the reflector 130 may not be housed within the same radome 140 as the feed network 110 and radiating element 120. The radome 140 has good electromagnetic wave penetration to ensure normal transmission and reception of electromagnetic waves between the radiating element 120 and the outside world. Furthermore, the radome 140 also has good stress resistance and oxidation resistance to withstand the erosion of harsh external environments. Exemplarily, the material of the radome 140 includes, but is not limited to, thermosetting and thermoplastic materials such as fiberglass, polyvinyl chloride (PVC), or plastics copolymerized from styrene, acrylonitrile, and acrylate rubber (ASA plastic).
[0094] As described above, the feed network 110 is mainly used to realize bidirectional signal transmission between the radiating unit 120 and the radio frequency processing unit. In the prior art, the transmission lines of the feed network are usually surrounded by a plastic frame to restrict the position and shape of the transmission lines. The plastic frame is an injection-molded structure. Due to the influence of molding precision and deformation, the plastic frame often needs to be segmented and then spliced into a whole. Therefore, in the design and processing, it is necessary to consider not only the internal pressing point connection of a single plastic segment, but also the connection problem of multiple injection-molded segments. This results in a relatively complex structure of the plastic frame and a relatively large amount of glue used, which in turn leads to a higher material cost and relatively larger transmission loss of the feed network.
[0095] Furthermore, during signal transmission in the power supply network, the transmission line, acting as the signal carrier, will inevitably generate heat, and the temperature of the plastic frame will also rise synchronously. With temperature changes, both the transmission line and the plastic frame will undergo some expansion and contraction deformation. Referring to Figure 4, which shows the deformation of transmission line 01 and plastic frame 02 under the same temperature difference, the deformation of the transmission line ΔL1 = L1 * ε1 * ΔT, and the deformation of plastic frame 02 ΔL2 = L2 * ε2 * ΔT. Here, L1 and L2 are the original lengths of transmission line 01 and plastic frame 02, respectively; ε1 is the coefficient of thermal expansion (CTE) of transmission line 01; ε2 is the coefficient of thermal expansion of plastic frame 02; and ΔT is the temperature difference.
[0096] It can be seen that due to the difference in the coefficients of thermal expansion between transmission line 01 and plastic frame 02, they will elongate differently under the same temperature difference. Furthermore, because transmission line 01 is entirely encased in plastic frame 02, when the elongation of plastic frame 02 is relatively small, the elongation deformation of transmission line 01 is restricted by plastic frame 02, causing transmission line 01 to warp. The warping deformation of transmission line 01 will affect the electrical performance indicators of the feed network, and in severe cases, may even lead to extreme situations such as short circuits, affecting the normal communication of the antenna.
[0097] In view of this, embodiments of this application provide a power supply network to reduce the material cost and transmission loss of the power supply network, and to improve the reliability of the power supply network. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0098] Figure 5 is a partial structural schematic diagram of a feed network 110 provided in an embodiment of this application, and Figure 6 is a partial exploded structural schematic diagram of the feed network 110 shown in Figure 5. The feed networks 110 shown in Figures 5 and 6, as well as the feed networks provided in the embodiments below, can all be applied to the antenna shown in Figure 3, and the functions implemented by the feed networks 110 shown in Figures 5 and 6, as well as the feed networks provided in the embodiments below, are basically the same as the functions of the feed network in Figure 3.
[0099] Referring to Figures 5 and 6, in this embodiment of the application, the power supply network 110 includes a metal floor 11, a transmission line 12, and a plurality of fasteners 13. The plurality of fasteners 13 are disposed on the metal floor 11, and the fasteners 13 may protrude from at least one side surface of the metal floor 11 along the thickness direction. The transmission line 12 is fixedly connected to the portion of the fasteners 13 protruding from the surface of the metal floor 11, and the transmission line 12 is spaced apart from the surface of the metal floor 11.
[0100] The metal floor 11 can be made of, but is not limited to, aluminum. The metal floor 11 is used to support the transmission line 12 and the fastener 13, providing positioning and assembly for the transmission line 12 and the fastener 13. In addition, the metal floor 11 can also provide shielding for the transmission line 12, reducing radiation loss of the signal transmitted in the transmission line 12.
[0101] The transmission line 12 can extend along the length of the metal floor 11. In one example, the transmission line 12 is a metal strip, and its material can be, but is not limited to, aluminum. Exemplarily, the transmission line 12 can be an aluminum sheet metal strip formed by sheet metal processing. This type of transmission line 12 has a certain shape retention capability and can be suspended flatly on the surface of the metal floor 11 under the support of the fixing member 13. In another implementation, the transmission line 12 can include multiple branches 121, which can be connected to each other or spaced apart; or, the transmission line 12 can also be a single complete branch. The specific shape of the transmission line 12 can be designed according to the communication requirements of the antenna, and this application does not limit it in this regard.
[0102] The fixing member 13 is made of a dielectric material, which has relatively high dielectric strength, thus ensuring reliable insulation between the transmission line 12 and the metal ground 11. Exemplarily, the fixing member 13 can be made of plastic. Multiple fixing members 13 are discretely distributed on the metal ground 11, spaced apart from each other or in contact with each other. Each fixing member 13 provides at least one fixing point for the transmission line 12. Here, discrete distribution can be understood as the fixing members 13 exhibiting a small size and large number of components. The maximum length or maximum width of the fixing member 13 is generally less than or equal to 50 mm. Exemplarily, the maximum length or maximum width of the fixing member 13 can be 50 mm, 40 mm, 35 mm, 25 mm, etc. Of course, in some embodiments, the maximum length or maximum width of the fixing member 13 can also be greater than 50 mm.
[0103] In one implementation, the fastener 13 can be pre-installed on the metal floor 11 and integrated with it as a single unit. For example, the fastener 13 can be directly formed on the metal floor 11 by injection molding. This eliminates the assembly step between the fastener 13 and the metal floor 11, simplifying the manufacturing process of the power supply network 110. It also avoids assembly tolerances between the fastener 13 and the metal floor 11, thereby reducing the alignment difficulty of assembling the transmission line 12 with the metal floor 11 on which the fastener 13 is installed and improving the overall accuracy of the power supply network 110.
[0104] Of course, in other implementations, the fastener 13 can also be manufactured separately and then assembled onto the metal floor 11; this application does not impose any restrictions on this. In engineering applications, a suitable process method can be selected based on process conditions or requirements.
[0105] In this embodiment, multiple fasteners 13 fix the transmission line 12 at multiple points relative to the metal floor 11, thus ensuring that the transmission line 12 can be reliably suspended on the surface of the metal floor 11. Furthermore, compared to a single, integral plastic frame, the discretely arranged fasteners 13 effectively reduce the amount of plastic material used while reliably supporting the transmission line 12, thereby reducing the cost of the plastic material and the weight of the power supply network 110, and also lowering the transmission loss of the transmission line 12.
[0106] Furthermore, when the transmission line 12 and the metal floor 11 are made of the same metal material (e.g., aluminum), their coefficients of thermal expansion are relatively close. Therefore, under the same temperature difference, the deformation of the transmission line 12 is approximately the same as that of the metal floor 11. Since the fastener 13 is fixed to the metal floor 11, its position can change with the deformation of the metal floor 11. When the deformation of the metal floor 11 is comparable to that of the transmission line 12, the positional change of the fastener 13 can essentially match the deformation of the transmission line 12. This reduces the risk of warping or other deformations in the transmission line 12 and improves the electrical performance of the power supply network 110.
[0107] Please continue referring to Figures 5 and 6. In some embodiments, the antenna's radiating element is a dual-polarized radiating element. In this case, the transmission line 12 may include a first sub-transmission line 12a and a second sub-transmission line 12b. The first sub-transmission line 12a can be used to transmit radio frequency signals in a first polarization direction, and the second sub-transmission line 12b can be used to transmit radio frequency signals in a second polarization direction. The fixing member 13 may protrude from both sides of the metal ground plane 11 along its thickness direction. The first sub-transmission line 12a may be fixedly connected to the portion of the fixing member 13 protruding from one side of the metal ground plane 11, and the second sub-transmission line 12b may be fixedly connected to the portion of the fixing member 13 protruding from the other side of the metal ground plane 11. This fully utilizes the space on both sides of the metal ground plane 11, enabling the feed network 110 to match the signal transmission requirements of the dual-polarized radiating element with a relatively small size, which helps to achieve miniaturized antenna design.
[0108] Figures 5 and 6 illustrate the example of transmission lines 12 being disposed on both sides of the metal floor 11 along the thickness direction. In other embodiments, transmission lines 12 may also be disposed on only one side of the metal floor 11 along the thickness direction. Accordingly, the fastener 13 fixes the transmission lines 12 by the portion of its protrusion from one side of the metal floor 11.
[0109] Figure 7 is a partial structural schematic diagram of a power supply network 110 provided in an embodiment of this application. Referring to Figure 7, in this embodiment, the power supply network 110 may further include a dielectric block 14, which may be disposed between the transmission line 12 (shown as a dashed line) and the metal ground plane 11. The dielectric block 14 is fixedly connected to the fixing member 13 to be fixed to the metal ground plane 11 by the fixing member 13. This eliminates the need to add other components to fix the dielectric block 14, thereby simplifying the structure of the power supply network 110. Exemplarily, the dielectric block 14 and the fixing member 13 may be made of the same material, thus achieving material standardization and helping to reduce the production cost of the power supply network 110.
[0110] The thickness direction of the metal ground plane 11 is defined as the first direction x. The orthographic projection of the dielectric block 14 in the first direction x covers the orthographic projection of the transmission line 12 in the first direction x. The transmission parameters of the transmission line 12 can be adjusted using the dielectric block 14, thereby adjusting the phase and impedance of the signal transmitted by the transmission line 12 and changing the radiation performance of the radiating element connected to the transmission line 12. The size and specific location of the dielectric block 14 can be designed according to the communication requirements of the antenna, and this application does not impose any limitations on this.
[0111] Figure 8 is a partial structural schematic diagram of a power supply network 110 provided in an embodiment of this application. Referring to Figure 8, in this embodiment, the power supply network further includes a phase shifter 20, which may be, but is not limited to, a reflective phase shifter, a loaded line phase shifter, a switch line phase shifter, a filter phase shifter, etc. In one implementation, the phase shifter 20 may be connected in the transmission line 12 to simplify the structural design of the power supply network 110, improve the integration level of the power supply network 110, and facilitate the installation and fixation of the power supply network 110 on the reflector.
[0112] In some other implementations, at least a portion of the phase shifter can be formed by transmission lines, which can effectively simplify the assembly and positioning of the power supply network 110 and improve the processing efficiency of the power supply network 110.
[0113] The phase shifter 20 is insulated from the metal floor 11. Exemplarily, the phase shifter 20 can be fixed relative to the metal floor 11 with an insulated gap by the aforementioned fastener 13, or it can be fixed to the metal floor 11 by other insulating elements.
[0114] In some embodiments, the power supply network 110 may also include other functional devices, including but not limited to one or more of combiners, drive or calibration networks, filters, connectors, and power dividers. The transmission line 12 can connect one or more functional devices to form a complete signal transmission system.
[0115] Figure 9 is a partial structural schematic diagram of a power supply network 110 provided in an embodiment of this application. Referring to Figure 9, in this embodiment, the fixing member 13 includes a sub-fixing member 131, so each fixing member 13 can provide a fixing point for the transmission line 12 using a sub-fixing member 131. The metal ground plate 11 is provided with openings 111 corresponding to the positions of each fixing member 13, and each fixing member 13 can be fixed to the metal ground plate 11 by being inserted into the corresponding openings 111. In addition, the shapes of multiple fixing members 13 can be the same, which is beneficial for the batch processing and forming of multiple fixing members 13 and simplifies the manufacturing process of the power supply network 110.
[0116] The sub-fixing member 131 may be, but is not limited to, a cylindrical, conical, prismatic, or other strip-shaped structure. For example, the sub-fixing member 131 is a cylindrical structure, and its cross-sectional shape may be circular, rectangular, triangular, or other regular or irregular polygonal shapes; this application does not limit this. Because the volume of a single sub-fixing member 131 is relatively small, its installation position is flexible, and it can be distributed in a dense or sparse discrete manner at various locations on the metal floor 11 to meet the fixing requirements of the transmission line 12.
[0117] Along the extension direction of the transmission line, the spacing between two adjacent sub-fixing members 131 is generally no greater than 35mm to improve the reliability of the support for the transmission line 12. For example, the spacing between two adjacent sub-fixing members 131 can be 35mm, 32mm, 25mm, 20mm, etc. In some special scenarios, such as areas where electrical performance is not critical, the spacing between two adjacent sub-fixing members can also be greater than 35mm.
[0118] Figure 10a is a schematic diagram of a sub-fixing member 131 of the power supply network 110 shown in Figure 9. Referring to Figures 9 and 10a together, in this embodiment, the sub-fixing member 131 includes a first portion 1311 and a second portion 1312 protruding from one side surface of the metal ground plate 11 along the thickness direction. The first portion 1311 is disposed between the transmission line 12 and the metal ground plate 11 to provide support for the transmission line 12. The second portion 1312 is connected to the side of the first portion 1311 away from the metal ground plate 11 and can be used to connect the transmission line. Exemplarily, the transmission line 12 is provided with a through hole 124 corresponding to the sub-fixing member 131, and the second portion 1312 can be inserted into the through hole 124.
[0119] The outer contour of the first part 1311 in the orthographic projection of the first part x exceeds the outer contour of the orthographic projection of the via 124 of the transmission line 12 in the first part x, so as to avoid the first part 1311 from penetrating into the via 124 and causing the transmission line 12 to make contact with the metal floor 11, thus ensuring the transmission performance of the transmission line 12.
[0120] In addition, the sub-fixing member 131 also includes a third part 1313, which is connected to the end of the first part 1311 away from the second part 1312. The orthographic projection of the third part 1313 in the first direction x is located within the range of the orthographic projection of the first part 1311 in the first direction x. The third part 1313 can be inserted into the opening 111 of the metal floor 11.
[0121] In one embodiment, the sub-fixing member 131 further includes a fourth portion 1314, which is connected to the end of the third portion 1313 away from the first portion 1311. The outer contour of the fourth portion 1314 in the orthographic projection of the first direction x exceeds the outer contour of the opening 111 of the metal ground 11 in the orthographic projection of the first direction x. In this way, the fourth portion 1314 and the first portion 1311 can respectively abut against the two side surfaces of the metal ground 11. That is, the sub-fixing member 131 snaps the metal ground 11 between the fourth portion 1314 and the first portion 1311, thereby fixing the sub-fixing member 131 relative to the metal ground 11. This type of sub-fixing member 131 can be applied to examples where the transmission line 12 is suspended on one side surface of the metal ground 11, and is suitable for cases where the radiating element of the antenna is a single-polarization radiating element.
[0122] Figure 10b is a schematic diagram of another sub-fixing member 131 provided in an embodiment of this application. Referring to Figure 10b, in this embodiment, the sub-fixing member 131 includes a first protrusion 1315 and a second protrusion 1316 protruding from both sides of the metal ground plate 11 along the thickness direction. Both the first protrusion 1315 and the second protrusion 1316 include a first portion 1311 and a second portion 1312. The second portion 1312 of the first protrusion 1315 is connected to the side of the first portion 1311 of the first protrusion 1315 away from the metal ground plate 11, and the second portion 1312 of the second protrusion 1316 is connected to the side of the first portion 1311 of the second protrusion 1316 away from the metal ground plate 11. This type of sub-fixing member 131 can be applied in examples where transmission lines 12 are suspended on both sides of the metal ground plate 11 (refer to Figure 6), and is suitable for cases where the antenna's radiating element is a dual-polarized radiating element.
[0123] In a specific implementation, the first portion 1311 of the first protrusion 1315 is spaced between the first sub-transmission line 12a and the metal ground plane 11, and the second portion 1312 of the first protrusion 1315 is inserted into the through hole of the first sub-transmission line 12a to connect the first sub-transmission line 12a; the first portion of the second protrusion 1316 is spaced between the second sub-transmission line 12b and the metal ground plane 11, and the fifth portion of the second portion 1312 of the second protrusion 1316 is inserted into the through hole of the second sub-transmission line 12b to connect the second sub-transmission line 12b.
[0124] Additionally, the sub-fixing member 131 may also include a third portion 1313, which is connected between the first protrusion 1315 and the second protrusion 1316. The third portion 1313 can be inserted into the opening 111 of the metal floor 11. The orthographic projection of the third portion 1313 in the first direction x is within the range of the orthographic projection of the first portion 1311 of the first protrusion in the first direction x, and the orthographic projection of the third portion 1313 in the first direction x is within the range of the orthographic projection of the first portion 1311 of the second protrusion in the first direction x.
[0125] Figure 11 is a schematic diagram of the structure of a power supply network 110 provided in this application during the manufacturing process. Referring to Figure 11, in this embodiment, the end of the second part 1312 protrudes from the surface of the transmission line 12 facing away from the metal floor 11. The end of the second part 1312 can be formed into a rivet head 13121 on the surface of the transmission line 12 facing away from the metal floor 11 by using a hot melt head 2000, thereby pressing the transmission line 12 between the rivet head 13121 and the end face of the first part 1311, realizing the fixed connection between the transmission line 12 and the sub-fixing member 131.
[0126] Figure 12 is a process flow diagram of forming the rivet head 13121 by hot melting. Referring to Figure 12, when forming the rivet head 13121, the hot melt head 2000 of the hot melt tooling is first aligned with the end of the second part 1312. Then, the hot melt head 2000 is pressed down towards the transmission line 12, causing the plastic material at the end of the second part 1312 to melt under the high temperature of the hot melt head 2000. After the end of the hot melt head 2000 contacts the surface of the transmission line 12, the molten plastic material fills the rivet head-shaped mold of the hot melt head 2000. Afterwards, the hot melt head 2000 is removed to demold the rivet head 13121. This process is not only simple and efficient, but also allows for a more robust connection between the transmission line 12 and the sub-fixed component 131, improving the structural reliability of the power supply network 110.
[0127] Typically, the hot melt tooling integrates multiple hot melt heads 2000. Therefore, in actual operation, the multiple hot melt heads 2000 of the hot melt tooling can be used for batch hot melting, which can form multiple rivet heads 13121 at one time, thereby improving the hot melting efficiency and thus helping to improve the overall production efficiency of the power supply network.
[0128] Figure 13 is a partial structural schematic diagram of a power supply network 110 provided in an embodiment of this application, and Figure 14 is a structural schematic diagram of the fixing member 13 of the power supply network 110 shown in Figure 13. Referring to Figures 13 and 14 together, in this embodiment, the fixing member 13 includes multiple sub-fixing members 131, which are connected into an integral structure by connecting ribs 132. For example, Figure 14 shows a case where the fixing member 13 includes three sub-fixing members 131, and adjacent sub-fixing members 131 are connected by connecting ribs 132. The multiple fixing members 13 can have the same shape, which is beneficial for the batch processing and forming of multiple fixing members 13 and simplifies the manufacturing process of the power supply network 110. The same shape here means that the number and arrangement of the sub-fixing members 131 of two fixing members 13 are the same.
[0129] Along the extension direction of the transmission line 12, the spacing between two adjacent sub-fixing members 131 in the fixing member 13 can be less than or equal to 35mm, and the spacing between adjacent fixing members 13 can also be less than or equal to 35mm, so as to improve the reliability of the support for the transmission line 12.
[0130] The metal floor 11 has openings 111 at the positions of each sub-fixing member 131 of the fixing member 13. Each sub-fixing member 131 of the fixing member 13 can be fixed to the metal floor 11 by being inserted into the corresponding openings 111.
[0131] Multiple sub-fixing members 131 of the fixing member 13 are respectively fixedly connected to the transmission line 12. Thus, each fixing member 13 can provide multiple fixing points for the transmission line 12 using its sub-fixing members 131. Therefore, the number of fixing members 13 required to fix the transmission line 12 to the metal floor 11 can be relatively reduced. The multiple sub-fixing members 131 and their connecting ribs 132 of the fixing member 13 can be integrally injection molded. This not only facilitates the processing of the individual fixing members 13, but also greatly simplifies the overall processing of the power supply network 110, thereby improving the processing efficiency of the power supply network 110.
[0132] In one embodiment, at least a portion of the connecting ribs 132 of the fastener 13 are staggered with the transmission line 12. For example, all the connecting ribs 132 of the fastener 13 may be staggered with the transmission line 12, or only a portion of the connecting ribs 132 of the fastener 13 may be staggered with the transmission line 12. Since the fastener 13 is made entirely of dielectric material, by staggering the connecting ribs 132 of the fastener 13 with the transmission line 12, the overlap area between the connecting ribs 132 and the transmission line 12 can be reduced, thereby reducing transmission loss caused by the dielectric and improving the signal transmission quality in the transmission line 12.
[0133] In this embodiment, the specific structure of each sub-fixing member 131 in the fixing member 13 and the fixing method of the sub-fixing member 131 and the transmission line 12 can be designed with reference to the embodiments shown in Figures 10a to 12, and will not be repeated here.
[0134] Figure 15 is a partial structural schematic diagram of a power supply network 110 provided in an embodiment of this application, and Figure 16 is a structural schematic diagram of the fixing member 13 of the power supply network 110 shown in Figure 15. Referring to Figures 15 and 16 together, in this embodiment, the fixing member 13 may also include multiple sub-fixing members 131, which are connected into an integral structure by connecting ribs 132. The multiple sub-fixing members 131 of the fixing member 13 are respectively fixedly connected to the transmission line 12 to fix the transmission line 12 relative to the metal floor 11 through the fixing member 13.
[0135] Among the multiple fasteners 13, at least two fasteners 13 may have different shapes. Different shapes here refer to at least one difference in the number and arrangement of the sub-fasteners 131 of the two fasteners 13. In one implementation, the two fasteners 13 have the same number of sub-fasteners 131, but different arrangements; in another implementation, the two fasteners 13 have different numbers of sub-fasteners 131, and their arrangements are roughly the same or different. For example, in Figure 16, fasteners b and c have the same shape, while fasteners a, b, d, and e each have different shapes. By increasing the diversity of the shapes of the fasteners 13, the fixing requirements of the transmission line 12 can be better adapted, improving the fixing flexibility of the transmission line 12 on the metal floor 11.
[0136] Similarly, the metal floor 11 has openings 111 at the positions of each sub-fixing member 131 of the fixing member 13. Each sub-fixing member 131 of the fixing member 13 can be fixed to the metal floor 11 by being inserted into the corresponding opening 111. In addition, due to the differences in the shape of the fixing member 13, the arrangement of the openings 111 of the metal floor 11 for each fixing member is not exactly the same, and can be designed according to the shape of the corresponding fixing member 13.
[0137] In this embodiment, the specific structure of each sub-fixing member 131 in the fixing member 13 and the fixing method of the sub-fixing member 131 and the transmission line 12 can be designed with reference to the embodiments shown in Figures 10a to 12, and will not be repeated here.
[0138] Figure 17 is a partial structural diagram of a power supply network 110 provided in an embodiment of this application. To clearly illustrate the design of the fasteners 13, the transmission line 12 is not shown in Figure 17. Referring also to Figures 17 and 18, in this embodiment, the multiple fasteners 13 include multiple identical fastener groups 13A arranged sequentially. Each fastener group 13A may contain one or more fasteners 13, and the fasteners 13 in each fastener group 13A may be disposed at one or more arrangement positions on the metal floor 11. Exemplarily, the multiple fastener groups 13A may be arranged sequentially along the length direction of the metal floor 11. Here, identical fastener groups 13A can be understood as having the same number of fasteners 13, the same shape of fasteners 13 located in the same arrangement position, and the same arrangement order of fasteners 13. Furthermore, the spacing between any two fasteners 13 in each fastener group 13A is the same as the spacing between two fasteners 13 located in the same arrangement position in the other fastener groups 13A.
[0139] During processing, one or more fasteners 13 in a fastener group 13A can be formed in one step. For example, if the fasteners 13 in fastener group 13A can be simultaneously injection molded using the same mold, then the fasteners 13 in the remaining fastener groups 13A can also be injection molded sequentially using the same mold. Taking a fastener group 13A comprising 5 fasteners 13 as an example, the mold used for injection molding can be equipped with 5 sub-molds and 5 nozzles. The 5 sub-molds are used to form 5 fasteners 13 respectively, and each nozzle can inject plastic material into a corresponding connected sub-mold. This processing method can greatly simplify the processing of multiple fasteners 13, and is more conducive to the automated mass production of the power supply network 110, thereby improving the production efficiency of the power supply network 110.
[0140] When the number of fasteners 13 in fastener group 13A is at least two, the shapes of the at least two fasteners 13 can be the same or different. For example, in the embodiment shown in FIG. 17, in each fastener group 13A, fastener b and fastener c have the same shape, while fastener a, fastener b, fastener d, and fastener e have different shapes. Of course, the shapes of each fastener 13 in fastener group 13A can also be completely identical. In specific implementations, the fasteners 13 of each fastener group 13A can be designed according to the shape of the transmission line 12, and this application does not impose any further limitations on this.
[0141] Alternatively, the fasteners 13 in the fastener group 13A can be arranged sequentially along the length of the metal floor 11, and the spacing between any two adjacent fasteners 13 in the fastener group 13A can be the same, thereby providing a relatively uniform supporting force for the transmission line. Alternatively, in other implementations, at least two of the spacings between any two adjacent fasteners 13 in the fastener group 13A are different, to make the layout of the fasteners 13 more flexible and improve the adaptability of the position of the fasteners 13 to the shape of the transmission line.
[0142] Referring to Figure 17, in this embodiment, the spacing between any two adjacent fastener groups 13A can be the same. Here, spacing refers to the distance between the position of the last fastener 13 in the previous fastener group 13A and the position of the first fastener 13 in the next fastener group 13A, along the arrangement direction of the multiple fastener groups 13A. This implementation can be viewed as multiple fastener groups 13A arranged periodically, with each fastener group 13A constituting one cycle. On the metal floor 11, at regular intervals, fasteners 13 of each shape can repeat within different fastener groups 13A. When the shape of the transmission line changes regularly, the periodically arranged multiple fastener groups 13A can more reliably fix the transmission line 12 to the metal floor 11.
[0143] Figure 18 is a partial structural diagram of a power supply network 110 provided in an embodiment of this application. Referring to Figure 18, in this embodiment, at least two of the spacings between any two adjacent fixing member groups 13A are different. For example, along the arrangement direction of the multiple fixing member groups 13A, the spacing between the first fixing member group 13A and the second fixing member group 13A is different from the spacing between the second fixing member group 13A and the third fixing member group 13A. The multiple fixing member groups 13A are arranged in an unequal spacing manner, which can improve the layout flexibility of the fixing members 13, thereby meeting the fixing requirements of transmission lines 12 with various shapes.
[0144] Figure 19 is a partial structural diagram of a power supply network 110 provided in an embodiment of this application. Referring to Figure 19, in this embodiment, the plurality of fasteners 13 include a plurality of fastener groups 13A arranged sequentially. The number of fasteners 13 in each fastener group 13A can be at least two, and the fasteners 13 in each fastener group 13A can be disposed in at least a portion of the plurality of arrangement positions of the metal floor 11. Specifically, at least one of the plurality of arrangement positions corresponding to at least one fastener group 13A is not provided with a fastener 13, while in the plurality of arrangement positions corresponding to the remaining fastener groups 13A, the same arrangement position as the at least one arrangement position is provided with a fastener 13, and the fasteners 13 in the same arrangement positions corresponding to the remaining fastener groups 13A have the same shape. That is, at least one fastener group 13A is missing at least one fastener, while the remaining fastener groups 13A have fasteners of the same shape at the same position as the missing fastener 13.
[0145] For example, along the arrangement direction of multiple fastener groups 13A, fasteners 113 are provided at multiple arrangement positions corresponding to the first fastener group 13A; fastener b is not provided at the second arrangement position corresponding to the second fastener group 13A, while the shape of fastener b is the same at the second arrangement position corresponding to the other fastener groups 13A. Fastener c and fastener d are not provided at the third and fourth arrangement positions corresponding to the third fastener group 13A, while the shape of fastener c is the same at the third arrangement position, and the shape of fastener d is also the same at the fourth arrangement position.
[0146] This embodiment can effectively improve the layout flexibility of the fasteners 13 by rationally designing the number of fasteners 13 in each fastener group 13A. Furthermore, it can reduce the number of fasteners 13 while ensuring that the transmission line is reliably fixed to the metal floor 11, thereby reducing the amount of plastic material used and lowering the material cost of the power supply network.
[0147] Furthermore, in this embodiment, the spacing between any two adjacent fastener groups 13A can be the same or different. When the spacing between any two adjacent fastener groups 13A is the same, the multiple fastener groups 13A can be considered as being arranged in a non-uniform periodic pattern, with each fastener group 13A constituting one period. Fastener groups 13A lacking fasteners 13 are non-integer periods, while fastener groups 13A without missing fasteners 13 are integer periods. For example, along the arrangement direction of the multiple fastener groups 13A, the first fastener group 13A is an integer period, while the second and third fastener groups 13A are non-integer periods.
[0148] During the processing of the fasteners 13 in each fastener group 13A, for fastener groups 13A that do not lack fasteners 13, all the nozzles of the injection mold can be opened, so that each sub-mold can be simultaneously injection molded to form multiple fasteners 13; for fastener groups 13A that lack one or more fasteners 13, the nozzles in the injection mold corresponding to the one or more fasteners 13 can be closed, so that no plastic material is injected into the sub-mold connected to the closed nozzle, and thus the fasteners 13 cannot be formed in the corresponding arrangement position.
[0149] In engineering applications, operators can control the opening or closing of each nozzle of the injection mold through a program based on the status of the fixing components to improve processing efficiency. The specific implementation process will not be elaborated here.
[0150] Figure 20 is a structural schematic diagram of a power supply network 110 provided in an embodiment of this application, and Figure 21 is a partially exploded structural schematic diagram of the power supply network 110 shown in Figure 20. Referring to Figures 20 and 21 together, in this embodiment of the application, the power supply network 110 further includes a dielectric plate 15, and transmission lines 12 are disposed on the surface of the dielectric plate 15 facing away from the metal floor 11. The dielectric plate 15 mainly serves to support the transmission lines 12, and its material includes, but is not limited to, epoxy resin, polyethylene terephthalate (PET) plastic, polypropylene (PP) plastic, or other pure or composite plastic materials. The transmission lines 12 can be a copper layer, aluminum foil, or copper foil disposed on the surface of the dielectric plate 15, or they can be other metal films or metal plates.
[0151] In this embodiment, the fixing member 13 can be connected to the dielectric substrate, and the dielectric substrate 15 is used to achieve a fixed connection with the transmission line 12. With this design, the multiple fixing members 13 and the transmission line 12 can be relatively decoupled, which not only reduces the positioning difficulty of the fixing members 13, but also makes it easier to match the size and winding of the transmission line 12, thereby helping to reduce the connection difficulty between the transmission line 12 and the radiating element of the antenna.
[0152] In one implementation, the dielectric substrate 15 is provided with a through hole 151, and the sub-fixing member 131 of the fixing member 13 can be connected to the dielectric substrate 15 by passing through the through hole 151. It should be understood that among the multiple fixing members 13, there may be one or more fixing members 13 whose orthographic projection in the first direction x coincides or partially coincides with the orthographic projection of the transmission line 12 in the first direction x. In this case, a through hole 124 can still be provided at the position of the sub-fixing member 131 of the fixing member 13 on the transmission line 12, so that the sub-fixing member 131 can be sequentially passed through the dielectric substrate 15 and the transmission line 12.
[0153] In one implementation, multiple fasteners 13 have the same shape and can be arranged at equal intervals on the metal floor 11 to simplify the processing of the multiple fasteners 13 and improve the production efficiency of the power supply network. The fasteners 13 can be in the form of a single sub-fastener 131 or multiple sub-fasteners 131; this embodiment does not limit this. Furthermore, the sub-fasteners 131 can be fixed relative to the transmission line 12 by heat fusion as described in the previous embodiment, or by snap-fitting or riveting.
[0154] In some other implementations, the multiple fasteners 13 may also take different shapes, or the multiple fasteners 13 may be arranged in a non-periodic manner.
[0155] Figure 22 is a structural schematic diagram of a power supply network 110 provided in an embodiment of this application, and Figure 23 is a partially exploded structural schematic diagram of the power supply network 110 shown in Figure 22, illustrating one implementation of the sub-fixing member 131 being snapped and fixed to the transmission line 12. Referring to Figures 22 and 23 together, in this embodiment, a buckle 1317 is provided at the end of the second part 1312 of the sub-fixing member 131. Exemplarily, the buckle 1317 can be an inverted L-shaped structure, and the buckle 1317 has a limiting surface 13171 facing the surface of the metal floor 11, with a gap between the limiting surface 13171 and the end face of the first part 1311 of the sub-fixing member 131. During the injection molding process of the fixing member 13, the buckle 1317 can be formed by means of a slider or a slanted top.
[0156] When assembling the transmission line 12 with the metal floor 11, the transmission line 12 is first lowered vertically from above the metal floor 11, so that the second part 1312 of the sub-fixing member 131 of each fixing member 13 passes through the through hole 124 of the transmission line 12 and / or the through hole 151 of the dielectric plate 15. Then, the transmission line 12 is moved horizontally so that it is pressed between the limiting surface 13171 of the clip 1317 and the end face of the first part 1311. In this way, the clip 1317 can be snapped onto the surface of the transmission line 12 facing away from the metal floor 11. After the transmission line 12 is snapped onto the sub-fixing member 131, the metal floor 11 and the transmission line 12 can be fastened together by one or more rivets 16 to improve the structural reliability of the power supply network 110.
[0157] Figure 24 is a structural schematic diagram of a power supply network 110 provided in an embodiment of this application, and Figure 25 is a partially exploded structural schematic diagram of the power supply network 110 shown in Figure 24, illustrating another implementation of the snap-fit fixing of the sub-fixing member 131 and the transmission line 12. Referring to Figures 24 and 25 together, in this embodiment, the second part 1312 of the sub-fixing member 131 is provided with a snap-fit 1317. The snap-fit 1317 includes one or more elastic arms 13172 disposed along the periphery of the second part 1312. The first end of the elastic arm 13172 is connected to the end of the second part 1312, and the elastic arm 13172 is inclined in a direction away from the periphery of the second part 1312. There is a gap between the second end of the elastic arm 13172 and the end face of the first part 1311. During the injection molding process of the fixing member 13, the snap-fit 1317 can be formed by means of a slider or a slanted ejector.
[0158] When assembling the transmission line 12 with the metal floor 11, the transmission line 12 is first lowered vertically from above the metal floor 11. During the process of the buckle 1317 of the second part 1312 passing through the through hole 124 of the transmission line 12 and / or the through hole 151 of the dielectric plate 15, the elastic arm 13172 of the buckle 1317 deforms under the squeezing action of the inner wall of the through hole 124 and / or the through hole 151, so that the elastic arm 13172 is close to the peripheral surface of the second part 1312. After the buckle 1317 of the second part 1312 passes through the through hole 124 and / or the through hole 151, the elastic arm 13172 returns to its inclined position, and the transmission line 12 is pressed between the second end of the elastic arm 13172 and the end face of the first part 1311. In this way, the buckle 1317 can be snapped onto the surface of the transmission line 12 away from the metal floor 11.
[0159] In some other embodiments, the second portion 1312 of the sub-fixing member 131 may also be provided with a fixing hole and a rivet riveted to the fixing hole. During the assembly of the transmission line 12 with the metal floor 11, after the transmission line 12 is lowered vertically until the second portion 1312 of the sub-fixing member 131 passes through the through hole 124 of the medium plate 15, the rivet is riveted from the end of the second portion 1312 to the fixing hole, and the transmission line 12 is pressed between the rivet head 13121 of the rivet and the end face of the first portion 1311.
[0160] The aforementioned snap-fit or riveting methods between the sub-fixed component 131 and the transmission line 12 are simple and convenient, and have relatively low requirements for tooling equipment, thus facilitating the assembly of the power supply network 110 in various situations. Furthermore, these connection methods can be used not only for fixing with dielectric plate 15 as shown in Figures 22 to 26, but also for fixing without dielectric plate 15 as shown in Figures 4 to 15.
[0161] Figure 26 is a partial structural schematic diagram of a power supply network 110 provided in an embodiment of this application, and Figure 27 is a side view of the power supply network 110 shown in Figure 26. Referring to Figures 26 and 27 together, in this embodiment of the application, the power supply network 110 further includes a metal side plate 17 disposed on at least one side of the metal floor 11 along the width direction, and the metal side plate 17 extends along the length direction of the metal floor 11. By providing the metal side plate 17 on the side of the metal floor 11, the transmission line 12 can be protected on the one hand, reducing the radiation loss of the signal in the transmission line 12, and on the other hand, it does not affect the exposure of the surface of the metal floor 11 used to house the transmission line 12. That is, the space above the surface of the metal floor 11 is open, which allows the metal floor 11 to have greater assembly freedom, supports the vertical installation of the transmission line 12, and facilitates the inspection of the assembly effect.
[0162] Figures 28a and 28b are simplified structural schematic diagrams of two types of power supply networks 110 provided in this application. Referring also to Figures 28a and 28b, in this embodiment, the power supply network 110 includes two metal side plates 17, which are respectively disposed on both sides of the metal floor 11 along the width direction to form protection on both sides of the metal floor 11 and reduce the radiation loss of the transmission line 12.
[0163] In one embodiment, referring to FIG28a, the transmission line 12 includes a first sub-transmission line 12a and a second sub-transmission line 12b, which are respectively suspended on the two side surfaces of the metal floor 11. Two metal side plates 17 are respectively positioned beyond the two side surfaces of the metal floor 11 along the first direction x. The width direction of the metal floor 11 is defined as the second direction y. The orthographic projection of the metal side plates 17 in the second direction y covers the orthographic projection of the first sub-transmission line 12a in the second direction y, and the orthographic projection of the metal side plates in the second direction y covers the orthographic projection of the second sub-transmission line 12b in the second direction y, thereby improving the protection effect on the first sub-transmission line 12a and the second sub-transmission line 12b.
[0164] In one embodiment, referring to FIG28b, the transmission line 12 is suspended on one side surface of the metal floor 11. The side of the metal side plate 17 along the first direction x can extend beyond the side surface of the metal floor 11, and the orthographic projection of the metal side plate 17 in the second direction covers the orthographic projection of the transmission line 12 in the second direction y, so as to improve the protection effect on the transmission line 12. The other side of the metal side plate 17 along the first direction x can be flush with the other side surface of the metal floor 11, so as to reduce the size of the power supply network 110.
[0165] Figure 29 is a simplified structural schematic diagram of two power supply networks 110 provided in this application. Referring to Figure 29, in this embodiment, the power supply network 110 includes a metal side plate 17, which is disposed on one side of the metal floor along the second direction y to form protection on that side of the metal floor 11. The transmission line 12 may include a first sub-transmission line 12a and a second sub-transmission line 12b, which are respectively suspended on the two side surfaces of the metal floor 11. The two sides of the metal side plate 17 along the first direction x may extend beyond the two side surfaces of the metal floor 11. The orthographic projection of the metal side plate 17 in the second direction y covers the orthographic projection of the first sub-transmission line 12a in the second direction y, and the orthographic projection of the metal side plate 17 in the second direction y covers the orthographic projection of the second sub-transmission line 12b in the second direction y.
[0166] In another embodiment, the transmission line 12 may also be suspended on one side surface of the metal floor 11. In this case, the metal side plate 17 can be designed with reference to the embodiment shown in FIG28b, which will not be described in detail here.
[0167] Figures 30a and 30b are simplified structural schematic diagrams of two power supply networks 110 provided in embodiments of this application. Referring also to Figures 30a and 30b, in this embodiment, the power supply network 110 further includes a metal partition 18 disposed on at least one side surface of the metal floor 11 along a first direction x, the metal partition 18 extending along the length direction of the metal floor 11. There can be one or more metal partitions 18, which can divide the surface of the metal floor 11 into at least two regions. Multiple fasteners 13 can be disposed in the at least two regions. The transmission line 12 includes multiple branches 121, and the fasteners 13 in each region can be used to connect at least one branch 121, that is, at least one branch 121 is suspended above a region of the surface of the metal floor 11.
[0168] In this embodiment, the metal partition 18 can isolate multiple branches 121 of the transmission line 12, thereby reducing the mutual influence between signals transmitted in the multiple branches 121 of the transmission line 12 and improving the signal transmission quality.
[0169] In one embodiment, referring to FIG30a, the transmission line 12 includes a first sub-transmission line 12a and a second sub-transmission line 12b, which are respectively suspended on the two side surfaces of a metal floor 11. Metal partitions 18 may be respectively disposed on the two side surfaces of the metal floor 11. The orthographic projection of the metal partition 18 on one side surface of the metal floor 11 in the second direction y covers the orthographic projection of each branch 121 of the first sub-transmission line 12a in the second direction y, and the orthographic projection of the metal partition 18 on the other side surface of the metal floor 11 in the second direction y covers the orthographic projection of each branch 121 of the second sub-transmission line 12b in the second direction y, thereby improving the isolation effect between the branches 121 of the first sub-transmission line 12a and between the branches 121 of the second sub-transmission line 12b.
[0170] In one embodiment, referring to FIG30b, the transmission line 12 is suspended on one side surface of the metal floor 11, and the metal partition 18 is disposed on the side surface of the metal floor 11. The orthographic projection of the metal partition 18 in the second direction y covers the orthographic projection of each branch 121 of the transmission line 12 in the second direction y, so as to improve the isolation effect between the branches 121 of the transmission line 12.
[0171] Figure 31 is a simplified structural diagram of two types of power supply networks 110 provided in this application. Referring to Figure 31, in this embodiment, the power supply network 110 includes a metal side plate 17 disposed on at least one side of the metal floor 11 along the second direction y, and the power supply network 110 also includes a metal partition 18 disposed on one side surface of the metal floor along the first direction x. In this way, the metal side plate 17 can form protection on the side of the metal floor 11, and the metal partition 18 can isolate multiple branches 121 of the transmission line 12, thereby improving the signal transmission quality of the power supply network 110.
[0172] In one embodiment, the transmission line 12 includes a first sub-transmission line 12a and a second sub-transmission line 12b, which are respectively suspended on the two side surfaces of the metal floor 11. The orthographic projection of the metal side plate 17 in the second direction y covers the orthographic projection of the first sub-transmission line 12a in the second direction y, and the orthographic projection of the metal side plate 17 in the second direction y covers the orthographic projection of the second sub-transmission line 12b in the second direction y. Metal partitions 18 are respectively disposed on the two side surfaces of the metal floor 11. The orthographic projection of the metal partition 18 on one side surface of the metal floor 11 in the second direction y covers the orthographic projection of each branch 121 of the first sub-transmission line 12a in the second direction y, and the orthographic projection of the metal partition 18 on the other side surface of the metal floor 11 in the second direction y covers the orthographic projection of each branch 121 of the second sub-transmission line 12b in the second direction y.
[0173] In another embodiment, the transmission line 12 can also be suspended on one side surface of the metal floor 11. In this case, the metal side plate 17 can be designed according to the embodiment shown in FIG28b, and the metal partition 18 can be designed according to the embodiment shown in FIG30b. Further details will not be provided here.
[0174] Figure 32 is a structural schematic diagram of a power supply network 110 provided in an embodiment of this application, and Figure 33 is a partially exploded structural schematic diagram of the power supply network 110 shown in Figure 32. Referring to Figures 32 and 33 together, in this embodiment of the application, the power supply network 110 includes metal side plates 17 respectively disposed on both sides of a metal floor 11 along the second direction y, and the power supply network 110 also includes an extension plate 19. The extension plate 19 is connected to the side of a metal side plate 17 facing away from the metal floor 11, and the extension plate 19 extends along the second direction y. The metal side plate 17 may be provided with one or more openings 171, which can connect the two sides of the metal side plate 17 along the second direction y.
[0175] When the feed network 110 is installed in the antenna, the extension plate 19 can be inserted into the clearance hole 1301 of the reflector 130 (see FIG3). The output end of the transmission line 12 can be connected to the extension plate 19 through the opening 171 and connected to the radiating element of the antenna through the extension plate 19.
[0176] In addition, in this embodiment, the transmission line 12 may include a first transmission line 12a and a second transmission line 12b, which are respectively suspended on both sides of the metal floor 11. Alternatively, the transmission line 12 may also be suspended on one side of the metal floor 11, and this application does not limit this.
[0177] In the above embodiments, the metal side plate 17, metal partition 18, and extension plate 19 can be integrally formed with the metal floor 11, or they can be formed separately and then assembled onto the metal floor 11. Exemplarily, the metal floor 11, metal side plate 17, metal partition 18, and extension plate 19 can be processed, but not limited to, by sheet metal forming, machining, or pultrusion profiles.
[0178] Figure 34 is a simplified partial structural diagram of a feed network 110 provided in an embodiment of this application. The figure shows a simplified structure on one side of the metal ground plane 11, and the simplified partial structures of all the above embodiments can be illustrated by this figure. Referring to Figure 34, on one side of the metal ground plane 11 along the thickness direction, the transmission line 12 is suspended on the surface of that side of the metal ground plane 11 by a fixing member 13. The metal ground plane 11 is grounded. The metal ground plane 11 and the transmission line 12 can be regarded as a suspended microstrip line transmission system. This transmission system can not only reduce the radiation loss of the signal transmitted by the transmission line 12 to a certain extent, but also has a relatively small size and light weight, which helps to realize the miniaturization design of the antenna.
[0179] Figure 35 is a structural schematic diagram of a power supply network 110 provided in an embodiment of this application, and Figure 36 is a partially exploded structural schematic diagram of the power supply network 110 shown in Figure 35. Referring to Figures 35 and 36 together, in this embodiment of the application, the power supply network 110 further includes a metal housing 101. The metal ground plate 11, the transmission line 12, and a plurality of fasteners 13 can be assembled into a single unit and installed within the metal housing 101. The metal housing 101 is insulated from the metal ground plate 11 and the transmission line 12 to avoid affecting the signal transmission of the transmission line 12. Exemplarily, the metal housing 101 can be processed by sheet metal forming, machining, or profile forming processes.
[0180] In one embodiment, the metal housing 101 may be a semi-enclosed structure to facilitate the installation of the integrated structure comprising the metal floor 11, the transmission line 12, and multiple fasteners 13. The metal housing 101 includes a first sidewall 1011, a second sidewall 1012, and a third sidewall 1013. The first sidewall 1011 and the second sidewall 1012 are positioned opposite each other and spaced apart along a first direction x. The third sidewall 1013 connects the first sidewall 1011 and the second sidewall 1012. The metal floor 11 and other structures can be installed within the metal housing 101 from the opposite side of the third sidewall 1013. Within the metal housing 101, the metal floor 11 can be supported by insulating materials such as plastic to ensure that the metal floor 11 and the transmission line 12 are insulated from the various sidewalls of the metal housing 101.
[0181] In some other embodiments, the metal housing 101 may also be a fully enclosed structure. The metal housing 101 includes a first sidewall 1011, a second sidewall 1012, a third sidewall 1013, and a fourth sidewall. The first sidewall 1011 and the second sidewall 1012 are positioned opposite each other and spaced apart along a first direction x. The third sidewall 1013 and the fourth sidewall are respectively connected between the first sidewall 1011 and the second sidewall 1012, and are positioned opposite each other and spaced apart along a second direction y. Structures such as the metal floor 11 can be installed within the metal housing 101 from one end along its length.
[0182] In addition, in the embodiments of this application, the power supply network 110 may also include structures such as metal side plates, metal partitions and extension plates, which will not be described in detail here.
[0183] Figure 37 is a simplified partial structural diagram of the feed network shown in Figure 35, illustrating a simplified structure on one side of the metal ground plane 11. Referring to Figure 37, on one side of the metal ground plane 11, the transmission line 12 is suspended from that side surface of the metal ground plane 11 by a fixing member 13. The first sidewall 1011 of the metal housing 101 is located on the side of the transmission line 12 facing away from the metal ground plane 11. The metal ground plane 11 and the first sidewall 1011 are respectively grounded. Therefore, the metal ground plane 11, the first sidewall 1011, and the transmission line 12 disposed between them can be considered as a suspended stripline transmission line 12. This type of transmission line 12 can effectively reduce signal radiation loss, thereby improving signal transmission efficiency.
[0184] It is worth noting that in examples where the fastener includes multiple sub-fasteners, there may be locations where one or more sub-fasteners are located without transmission lines. In other words, some sub-fasteners are idle and do not serve to secure the transmission lines. In this case, the second part of the idle sub-fastener does not need to be hot-melted to form a rivet head; it can simply maintain its initial shape after injection molding to improve hot-melt efficiency and reduce hot-melt costs.
[0185] In some embodiments, the power supply network further includes a dielectric substrate that can be supported on the surface of the transmission line facing away from the metal ground plane. The structure of this power supply network is similar to a printed circuit board (PCB), and therefore the power supply network can be implemented using a PCB. The dielectric substrate serves to support the transmission line. The dielectric substrate is connected to a portion of a fixing element protruding from the surface of the metal ground plane, thus enabling relative fixation of the transmission line to the metal ground plane via the dielectric substrate.
[0186] In other embodiments, the power supply network further includes a dielectric substrate that may cover the outer surface of the transmission line, or the transmission line may be embedded within the dielectric substrate. The dielectric substrate is connected to a portion of the fixing member that protrudes from the surface of the metal ground plane, thus enabling relative fixation of the transmission line to the metal ground plane via the dielectric substrate.
[0187] In some other embodiments, the power supply network further includes a first dielectric layer structure and a second dielectric layer structure. The first dielectric layer structure is disposed on the side of the transmission line facing the metal floor, and the second layer structure is disposed on the side of the transmission line away from the metal floor. That is, the transmission line is sandwiched between the first dielectric layer structure and the second dielectric layer structure.
[0188] In one implementation, the first dielectric layer structure can be a dielectric substrate, and the second dielectric layer structure can be a dielectric film. The first dielectric layer structure carries the transmission line, while the second dielectric layer structure protects the transmission line and reduces the risk of corrosion. Furthermore, because the dielectric film is relatively thin, its weight is also relatively light, thus helping to reduce the overall weight of the power supply network. In another implementation, the first dielectric layer structure can be a dielectric film, and the second dielectric layer structure can be a dielectric substrate, thereby utilizing the second dielectric layer structure to carry the transmission line and the first dielectric layer structure to protect it.
[0189] Of course, in other implementations, both the first and second dielectric layer structures can be dielectric boards, so that the dielectric layer structures on both sides can both carry and protect the transmission line.
[0190] In this embodiment, at least one of the first dielectric layer structure and the second dielectric layer structure is connected to a portion of the fixing member protruding from the surface of the metal floor to achieve relative fixation between the transmission line and the metal base plate. For example, if one of the first dielectric layer structure and the second dielectric layer structure is a dielectric plate, at least the dielectric layer structure in the form of a dielectric plate is connected to the fixing member. Of course, both the first dielectric layer structure and the second dielectric layer structure can also be connected to the fixing member to improve the stability of the relative positional relationship between the transmission line and the metal base plate.
[0191] In the above embodiments, the dielectric substrate, the first dielectric layer structure, or the second dielectric layer structure is made of materials including, but not limited to, epoxy resin, PET plastic, PP plastic, or other pure or composite plastic materials. The transmission line can be a copper layer, aluminum foil, or other metal films or metal sheets.
[0192] 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.
