Description

Feeding networks, antenna devices and electronic equipment

[0001] This application claims priority to Chinese patent application filed on March 25, 2025, with application number 202510362177.4 and entitled "Feeding Network, Antenna Device and Electronic Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, specifically to a power supply network, antenna device, and electronic equipment. Background Technology

[0003] In recent years, mobile communication technology has made tremendous progress. A feed network is a physical structure that feeds radio frequency (RF) signals into a base station antenna array. A feed network is typically a tree-like structure composed of general transmission lines, its function being to distribute the energy from the total input port to the various antenna elements in the antenna array according to a certain proportion. Due to size constraints and signal transmission path design requirements from the input port to each output port, some sections of the transmission lines in a feed network need to be folded. However, in folded transmission lines, RF signals at locations with close proximity can interfere with each other, easily leading to signal quality degradation. To improve the signal transmission quality of feed networks, existing technologies often require additional structures to separate multiple transmission lines. However, feed networks with these structures are difficult to assemble and require sophisticated manufacturing processes.

[0004] Application content

[0005] In view of this, this application provides a power supply network, an antenna device, and an electronic device to improve the transmission quality of radio frequency signals in the power supply network and reduce assembly difficulty and manufacturing process requirements.

[0006] A first aspect of this application provides a power supply network including a first grounding cover, a second grounding cover, a transmission line, and a first isolation rib. The second grounding cover and the first grounding cover are disposed opposite each other along a first direction and form a transmission cavity. The transmission line is disposed within the transmission cavity and includes a plurality of spaced transmission segments. The first isolation rib includes a first rib, which includes a first end and a second end. The first end is connected to the first grounding cover, and the second end is spaced apart from the second grounding cover. Along the first direction, at least a portion of the projection of the first rib is located between two adjacent transmission segments.

[0007] In this application, the transmission cavity is formed by the first and second grounding covers, which facilitates processing and installation of the transmission line, thereby improving the transmission efficiency and fabrication efficiency of the feeder network. The first rib prevents electromagnetic interference between adjacent transmission segments, ensuring independent propagation of the RF signals in each transmission segment, avoiding crosstalk that could cause RF signal distortion or errors, improving the isolation between transmission segments, and enhancing the transmission efficiency and quality of the RF signals. This also helps reduce the spacing between adjacent transmission segments, thus reducing the size of the feeder network. Furthermore, the first end of the first rib is connected to the first grounding cover, while the second end is spaced apart from the second grounding cover. This eliminates the need for welding or direct molding methods like extrusion during feeder network fabrication, reducing manufacturing process requirements and facilitating subsequent assembly. The spacing between the second end and the second grounding cover also saves on the material used for the first rib, contributing to a lightweight feeder network design and reducing costs.

[0008] In one possible design, the first isolation rib further includes a second rib disposed on the second grounding cover plate; along the first direction of the power supply network, at least a portion of the projection of the second rib is located between two adjacent transmission segments; the second rib includes a third end and a fourth end, the third end being connected to the second grounding cover plate, and the fourth end being spaced apart from the first grounding cover plate.

[0009] The second rib further enhances the inter-line isolation between transmission segments, improving the transmission efficiency and quality of RF signals. It also helps reduce the spacing between adjacent transmission segments, thus decreasing the size of the feed network. During feed network fabrication, there's no need to connect the second end of the first rib to the second grounding cover using welding or similar methods, nor is it necessary to connect the fourth end of the second rib to the first grounding cover using welding or similar methods, further reducing fabrication process requirements. Furthermore, it saves on the material used in fabricating the first isolation rib, facilitating a lighter feed network design and reducing costs.

[0010] In one possible design, the second rib is spaced apart from the first rib along the first direction.

[0011] When the first grounding cover plate is connected to the second grounding cover plate, the second rib does not need to be aligned with the first rib, which improves the fault tolerance and yield in the preparation process. It also eliminates the need for welding or other connection methods, further reducing the requirements for the preparation process of the power supply network, improving the preparation efficiency of the power supply network, and reducing the preparation cost.

[0012] In one possible design, along the first direction, the projection of the first rib at least partially overlaps with the projection of the second rib. This structure reduces the space occupied by the corresponding first and second ribs in the second direction, which helps to reduce the spacing between two adjacent transmission segments and decrease the size of the power supply network.

[0013] In one possible design, the first rib and the second rib are spaced apart along the second direction of the power supply network, and the second direction intersects the first direction, thereby further improving the fault tolerance during the fabrication process and increasing the design freedom of the power supply network.

[0014] In one possible design, along the second direction of the power supply network, the first ribs and the second ribs are arranged alternately, and the transmission segment is disposed between two adjacent first ribs and second ribs, with the second direction intersecting the first direction.

[0015] Only one or two ribs are provided between two adjacent transmission segments. This improves the inter-line isolation between transmission segments and further reduces the space occupied by the first and second ribs between adjacent transmission segments. This helps to reduce the spacing between adjacent transmission segments and decrease the size of the feeder network. Furthermore, when connecting the first and second grounding covers, the second rib does not need to be aligned with the first rib, improving the fault tolerance and yield during fabrication. It also eliminates the need for welding or other connection methods, further reducing the fabrication process requirements of the feeder network, improving its fabrication efficiency, and lowering manufacturing costs.

[0016] In one possible design, the transmission line further includes multiple connecting segments whose extension directions intersect with the extension directions of the transmission segments. One end of each connecting segment is connected to a transmission segment, and the other end of each connecting segment is connected to another transmission segment, so that the multiple transmission segments are electrically connected to meet the signal transmission path design requirements from the input port to each output port of the power supply network, thus facilitating the transmission of radio frequency signals.

[0017] In one possible design, the first isolation rib is provided with a clearance groove; along the first direction, the connecting segment is located above the clearance groove; or, the connecting segment passes through the clearance groove along the first direction.

[0018] This structure avoids contact between the connecting section and the first isolation rib, further reducing the risk of short circuits in the transmission line and ensuring reliable transmission of radio frequency signals. Furthermore, the structure is simple, easy to fabricate, and can further reduce the structural complexity of the feed network, saving fabrication costs.

[0019] In one possible design, the power supply network further includes a second isolation rib, which is disposed at least in one of the first grounding cover and the second grounding cover; the extension direction of the second isolation rib intersects the extension direction of the first isolation rib, and along the first direction, the projection of the second isolation rib is located between two adjacent connection segments.

[0020] The addition of a second isolation rib can improve the inter-line isolation between two adjacent connection segments, thereby further improving the transmission efficiency and quality of RF signals. This also helps to reduce the spacing between two adjacent transmission segments, thus reducing the size of the feed network. Furthermore, through the cooperation of the second and first isolation ribs, appropriate second and first isolation ribs can be placed at the required locations according to the routing requirements of the transmission lines. This further improves the inter-line isolation of the transmission lines while also reducing the material used in the first isolation rib, which is beneficial for the lightweight design of the feed network and saves manufacturing costs.

[0021] In one possible design, the power supply network further includes an insulating element connected to both the first insulating rib and the transmission line, such that the transmission line is spaced apart from the first insulating rib.

[0022] This structure prevents the transmission line from contacting the first isolation rib, further reducing the risk of short circuits and ensuring reliable transmission of radio frequency signals. Furthermore, its simple structure is easy to implement and enhances the support and fixation of the transmission line, thereby improving the structural stability of the power supply network.

[0023] In one possible design, the insulating element is disposed between the connecting section and the first insulating rib to further reduce the material required for the insulating element, which is beneficial for the lightweight design of the power supply network and saves manufacturing costs.

[0024] In one possible design, along the first direction, the insulating component has multiple first through holes to form a porous mesh structure. This reduces the weight of the insulating component, facilitating lightweight design of the power supply network, saving costs, and also reducing the contact area between the insulating component and the transmission line, thus reducing the impact on the impedance and loss of the transmission line and improving the transmission performance of the radio frequency signal. Furthermore, the insulating component provides excellent insulation and support for the transmission line, preventing the transmission line from contacting grounding components such as the first grounding cover, the second grounding cover, the first isolation rib, and the second isolation rib, further reducing the risk of short circuits and ensuring reliable transmission of the radio frequency signal. Moreover, it eliminates the need for additional support components, reducing the number of parts used and further saving manufacturing costs.

[0025] In one possible design, the power supply network further includes a first support member and a second support member, the first support member being disposed between the transmission line and the first grounding cover plate, and the second support member being disposed between the transmission line and the second grounding cover plate.

[0026] The first and second support members provide good support for the transmission line, thereby ensuring a certain distance between the transmission line and the first and second grounding covers, preventing the transmission line from contacting the first and second grounding covers and short-circuiting, ensuring reliable transmission of radio frequency signals, and also improving the structural stability of the power supply network.

[0027] In one possible design, one of the first support member and the second support member is provided with a connecting post, and the other of the first support member and the second support member is provided with a connecting hole, wherein the connecting post is connected to the connecting hole.

[0028] This structure allows the first and second supports to be fixed on opposite sides of the transmission line along the first direction, further improving the structural stability of the feed network, which is beneficial for stable transmission of radio frequency signals and ensures the transmission quality of radio frequency signals. In addition, fixing the first and second supports on opposite sides of the transmission line along the first direction also facilitates the assembly of the feed network, further improving the fabrication efficiency of the feed network.

[0029] In one possible design, the transmission line is provided with a second through hole, and the connecting post passes through the second through hole and connects to the connecting hole.

[0030] The second through hole can restrict the displacement of the first and second supports on the transmission line, thereby further improving the fixing effect of the first and second supports on the transmission line and thus further enhancing the structural stability of the power supply network.

[0031] In one possible design, the transmission segment includes a first segment and a second segment connected to each other, the first support and the second support are disposed in the second segment along a second direction of the power supply network, the size of the second segment is less than or equal to the size of the first segment, and the second direction intersects the first direction.

[0032] When the width of the second segment is less than or equal to the width of the first segment, the equivalent capacitance of the second segment, i.e. the capacitance between the second segment and the first and second grounding covers, can be reduced, thereby increasing the impedance of the second segment and reducing the influence of the first and second support members on the impedance of the second segment, thus ensuring the transmission performance of radio frequency signals.

[0033] In one possible design, along the second direction of the power supply network, a first connecting protrusion is provided on each of the opposite sides of the first grounding cover, and a second connecting protrusion is provided on each of the opposite sides of the second grounding cover. Along the first direction, the first connecting protrusion protrudes from the surface of the first grounding cover, and the second connecting protrusion protrudes from the surface of the second grounding cover. The first connecting protrusion and the second connecting protrusion are electrically connected, and at least a portion of the first connecting protrusion and the second connecting protrusion have a gap between them.

[0034] The structure of the first and second connecting protrusions facilitates the formation of a transmission cavity by the first and second grounding covers. The structure is simple and easy to manufacture. Furthermore, the gap between the first and second connecting protrusions ensures the electromagnetic shielding function of the transmission cavity while further reducing the requirements of the manufacturing process, improving the manufacturing efficiency of the power supply network, and reducing the manufacturing cost.

[0035] In one possible design, the power supply network further includes a third grounding cover plate, which is disposed between the first grounding cover plate and the second grounding cover plate to divide the transmission cavity into a first transmission cavity and a second transmission cavity arranged along the first direction. The power supply network includes a first transmission line and a second transmission line, with the first transmission line disposed in the first transmission cavity and the second transmission line disposed in the second transmission cavity. The first isolation rib further includes a third rib. Along the first direction, the third grounding cover plate has at least one side with the third rib, and at least a portion of the projection of the third rib is located between two adjacent transmission segments of the first transmission line and / or two adjacent transmission segments of the second transmission line, to form a multi-layer power supply network structure. This facilitates the stacking of multiple transmission lines and further improves the design freedom and integration of the power supply network.

[0036] In one possible design, the power supply network further includes a connector that passes through the third grounding cover. One end of the connector is electrically connected to the first transmission line, and the other end is electrically connected to the second transmission line, so as to electrically connect the first and second transmission lines to facilitate signal transmission between multiple transmission lines in the power supply network.

[0037] A second aspect of this application provides an antenna device, which includes an antenna element and a feed network as described in any of the above embodiments, wherein the transmission line of the feed network is electrically connected to the antenna element. Since the feed network has the aforementioned technical effects, the antenna device including this feed network should also have corresponding technical effects, which will not be elaborated further here.

[0038] A third aspect of this application provides an electronic device including the antenna device described above. Since the antenna device has the aforementioned technical effects, the electronic device including the antenna device should also have corresponding technical effects, which will not be elaborated further here.

[0039] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

Detailed Implementation

[0071] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0072] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0073] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0074] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0075] The following explains the terminology that may appear in the embodiments of this application.

[0076] Relative / Relative Settings: A relative setting to B can refer to A and B being face-to-face (opposite to, or face to face) settings.

[0077] Ground / Plug: This can broadly refer to at least a portion of any grounding layer, ground plane, or grounding metal layer within an electronic device (such as a mobile phone), or at least a portion of any combination of the aforementioned grounding layers, ground planes, or grounding components. "Ground / Plug" can be used for grounding components within an electronic device. In one embodiment, "Ground / Plug" can be the grounding layer of a circuit board in an electronic device, or a grounding metal layer formed by a frame within the electronic device or a thin metal film beneath the screen. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12-14-layer board with 8, 10, 12, 13, or 14 layers of conductive material, or components separated and electrically insulated by dielectric or insulating layers such as fiberglass or polymers. In one embodiment, the circuit board includes a dielectric substrate, a ground layer, and a trace layer, with the trace layer and ground layer electrically connected via vias. In one embodiment, components such as displays, touch screens, input buttons, transmitters, processors, memory, batteries, charging circuits, and system-on-chip (SoC) architectures may be mounted on or connected to a circuit board; or electrically connected to trace layers and / or ground layers in the circuit board.

[0078] The terms collinearity, coaxiality, coplanarity, symmetry (e.g., axial symmetry, or central symmetry), parallelism, perpendicularity, and similarity (e.g., same length, same width, etc.) mentioned in the embodiments of this application are all relative to the current technological level, and not absolute and strict mathematical definitions. For two collinear radiating stubs or two antenna elements, there may be a deviation of less than a predetermined threshold (e.g., 1 mm, 0.5 m, or 0.1 mm) in the line width direction between their edges. For two coplanar radiating stubs or two antenna elements, there may be a deviation of less than a predetermined threshold (e.g., 1 mm, 0.5 m, or 0.1 mm) in the direction perpendicular to their coplanar plane. For two parallel or perpendicular antenna elements, there may be a deviation of a predetermined angle (e.g., ±5°, ±10°).

[0079] This application provides an electronic device, an antenna device 100, and a feed network 102, which can be applied to fields such as radar, broadcasting, and communications. The electronic device can be a base station system, a wireless router, a mobile phone, a drone, a smart home device, an in-vehicle electronic device, a GPS device, or any other device with an antenna device and a feed network. Exemplarily, the electronic device is described as a base station system.

[0080] Please refer to Figure 1, which is a schematic diagram of the base station system provided in this application in some embodiments. As shown in Figure 1, the base station system consists of an antenna device 100, an antenna adjustment bracket 200, a fixing rod 300, a connector seal 400, a grounding device 500, etc. The base station system is a wireless communication interface device, capable of exchanging information with communication terminals in the area, such as wireless routers, mobile phones, drones, smart home devices, vehicle electronic devices, and GPS devices.

[0081] Please refer to Figure 2, which is a schematic diagram of the antenna device 100 in Figure 1 in some embodiments.

[0082] As shown in Figure 2, the antenna device 100 consists of an antenna array 101, a phase shifter 103, a transmission network 104 or a calibration network, a combiner 105 or a filter, and a radome 107. The antenna array 101 includes multiple antenna elements 108, which receive or transmit radio frequency (RF) signals through a feed network 102 composed of the phase shifter 103, transmission network 104, and combiner 105. The feed network 102 is a physical structure that feeds RF signals onto the base station antenna array 101. Specifically, the feed network 102 can feed RF signals to the antenna elements 108 in the antenna array 101 with a certain amplitude and phase. Alternatively, the feed network 102 can also transmit the wireless signals received by the antenna array 101 to the signal processing unit of the base station system through the antenna connector 106 with a certain amplitude and phase. The radome 107 is a structural component that protects internal components from external environmental influences. It has good electromagnetic wave penetration characteristics in terms of electrical performance and can withstand the effects of harsh external environments in terms of mechanical performance.

[0083] The feed network 102 is typically a tree-like structure composed of general transmission lines, which distributes the energy from the total input port to the various antenna elements 108 in the antenna array 101 according to a certain ratio. Within the same feed network 102, due to size limitations and signal transmission path design requirements from the input port to each output port, some sections of the transmission lines need to be folded. In folded transmission lines, the radio frequency signals at locations with close proximity can interfere with each other, easily leading to an imbalance in signal distribution. This results in the energy radiated by the antenna array 101 not being concentrated, reducing the coverage area of ​​the antenna device 100 and degrading signal quality.

[0084] With the development of antenna devices, more and more antenna arrays 101 and feed networks 102 are crammed into the same aperture area. In the same feed network, the spacing between the internal transmission lines is getting smaller and smaller, so the mutual interference between the lines is becoming more and more serious.

[0085] Please refer to Figure 3, which is a schematic diagram of a power supply network in the related art. As shown in Figure 3, in one embodiment, the power supply network 102' consists of multiple independent semi-open transmission cavities 1' and transmission lines 2' disposed in the transmission cavities 1'. This physically isolates each segment of the transmission lines 2', improving the isolation between the transmission lines 2' and thus achieving high-quality transmission of radio frequency signals. However, this structure is inconvenient for installing the transmission lines 2', and the overall cavity wall of the transmission cavity 1' is thick, resulting in high weight and cost.

[0086] Please refer to Figure 4, which is a schematic diagram of another power supply network structure in the related art. As shown in Figure 4, in another embodiment, the power supply network 102” is composed of a first grounding cover plate 1”, a second grounding cover plate 2”, and a transmission line 4”. The first grounding cover plate 1” has a first rib 11”, and the second grounding cover plate 2” has a second rib 21”. The first grounding cover plate 1” and the second grounding cover plate 2” are welded together, and the first rib 11” and the second rib 21” can be correspondingly connected to form multiple independent transmission cavities 3”. Each segment of the transmission line 4” is respectively placed in the corresponding transmission cavity 3”, thereby physically isolating the traces of the transmission line 4” and achieving high-quality transmission of radio frequency signals. However, in this structure, the formation of the transmission cavity 3” requires corresponding connection of the first rib 11” on the first grounding cover plate 1” with the second rib 21” on the second grounding cover plate 2”. Therefore, the manufacturing precision requirements for the grounding cover plate 1” and the second grounding cover plate 2” are high, and the welding connection method has high overall process requirements and high cost.

[0087] In view of this, this application provides a power supply network 102 to reduce the fabrication difficulty of the power supply network 102, improve the isolation between different segments of the transmission line, and improve the quality of radio frequency signal transmission.

[0088] Please refer to Figure 5, which is a cross-sectional schematic diagram of the power supply network provided in an embodiment of this application in a specific embodiment.

[0089] As shown in Figure 5, the power supply network 102 is composed of components such as a first grounding cover plate 1, a second grounding cover plate 2, a first isolation rib 3, and a transmission line 4.

[0090] As shown in Figure 5, the first grounding cover plate 1 and the second grounding cover plate 2 are used to ground the power supply network 102. The first grounding cover plate 1 and the second grounding cover plate 2 form a transmission cavity 8, which can provide good electromagnetic shielding function, reduce the interference of external electromagnetic fields on the power supply network 102, prevent the electromagnetic radiation generated by the power supply network 102 from affecting external equipment, and prevent resonance at specific frequencies, thus ensuring the stability and accuracy of radio frequency signal transmission in the power supply network 102.

[0091] For example, the first grounding cover 1 and / or the second grounding cover 2 can be made of metals such as copper, aluminum, gold, copper alloy, or aluminum alloy. For example, the first grounding cover 1 and / or the second grounding cover 2 can include an insulating substrate and a metal layer, with the metal layer disposed on the surface of the insulating substrate to enclose and form a transmission cavity 8. For example, the first grounding cover 1 and / or the second grounding cover 2 can be a copper-clad laminate. For example, the first grounding cover 1 and / or the second grounding cover 2 can include an insulating substrate and a metal wire layer, with the metal wire layer disposed within the insulating substrate to enclose and form the transmission cavity 8. The insulating substrate can be made of insulating materials such as plastic or epoxy resin, and the metal layer and metal wire layer can be made of metals such as copper, copper alloy, aluminum, or aluminum alloy. The specific configuration of the first grounding cover 1 and / or the second grounding cover 2 can be determined according to actual needs and is not limited herein.

[0092] As shown in Figure 5, transmission line 4 is used to transmit radio frequency signals. Transmission line 4 is disposed in transmission cavity 8 and includes multiple spaced transmission segments 41 to reduce the size of power supply network 102 and meet the signal transmission path design requirements from the input port to each output port of power supply network 102.

[0093] As shown in Figure 5, the first isolation rib 3 includes a first rib 31. Along the first direction Z of the feed network 102, the first rib 31 includes a first end 311 and a second end 312. The first end 311 is connected to one of the first grounding cover plate 1 or the second grounding cover plate 2, and the second end 312 is spaced apart from the other of the first grounding cover plate 1 or the second grounding cover plate 2. Along the first direction Z of the feed network 102, at least a portion of the projection of the first rib 31 is located between two adjacent transmission segments 41.

[0094] In this embodiment, as shown in Figure 5, the transmission cavity 8 is formed by the first grounding cover plate 1 and the second grounding cover plate 2, which facilitates processing and molding, and also facilitates the installation of the transmission line 4, thereby improving the transmission efficiency and fabrication efficiency of the feed network 102. The first rib 31 prevents electromagnetic interference between the radio frequency signals of two adjacent transmission segments 41, ensuring the independent propagation of the radio frequency signals of each transmission segment 41 of the transmission line 4, avoiding crosstalk that causes radio frequency signal distortion or errors, improving the line isolation between each transmission segment 41 of the transmission line 4, improving the transmission efficiency and quality of the radio frequency signal, and helping to reduce the spacing between two adjacent transmission segments 41, thereby reducing the size of the feed network 102. Furthermore, the first end 311 of the first rib 31 is connected to one of the first grounding cover plate 1 or the second grounding cover plate 2, while the second end 312 is spaced apart from the other of the first grounding cover plate 1 or the second grounding cover plate 2. Therefore, during the fabrication of the power supply network 102, it is unnecessary to connect the second end 312 of the first rib 31 to the first grounding cover plate 1 or the second grounding cover plate 2 by welding or other methods, or to use direct molding methods such as profile extrusion. This reduces the requirements of the fabrication process and facilitates subsequent assembly. Moreover, the spaced distance between the second end 312 and the first grounding cover plate 1 or the second grounding cover plate 2 saves on the fabrication material of the first rib 31, thus contributing to the lightweight design of the power supply network 102 and reducing costs.

[0095] Wherein, the first direction Z can be the thickness direction of the power supply network 102.

[0096] When the power supply network 102 is only provided with the first rib 31, for example, in the specific embodiment shown in FIG5, the first rib 31 can be provided on the first grounding cover plate 1, that is, the first end 311 of the first rib 31 is connected to the first grounding cover plate 1, and the second end 312 is spaced apart from the second grounding cover plate 2. Of course, the first rib 31 can also be provided on the second grounding cover plate 2, which is not limited here.

[0097] Please refer to Figure 6, which is an exploded schematic diagram of the power supply network provided in this application embodiment in another specific embodiment.

[0098] As shown in Figure 6, the first isolation rib 3 also includes a second rib 32. The first rib 31 is disposed on the first grounding cover plate 1, and the second rib 32 is disposed on the second grounding cover plate 2. Along the first direction Z of the feed network 102, at least a portion of the projection of the first rib 31 is located between two adjacent transmission segments 41, and at least a portion of the projection of the second rib 32 is located between two adjacent transmission segments 41. The placement of the second rib 32 can further improve the inter-line isolation between the transmission segments 41 of the transmission line 4, improve the transmission efficiency and quality of the radio frequency signal, and help reduce the spacing between two adjacent transmission segments 41, thereby reducing the size of the feed network 102.

[0099] Further, please refer to Figure 7, which is a cross-sectional schematic diagram of the power supply network provided in another specific embodiment of this application. As shown in Figure 7, the first end 311 of the first rib 31 is connected to the first grounding cover plate 1, and the second end 312 is spaced apart from the second grounding cover plate 2. The second rib 32 includes a third end 321 and a fourth end 322. The third end 321 of the second rib 32 is connected to the second grounding cover plate 2, and the fourth end 322 is spaced apart from the first grounding cover plate 1. Therefore, in the process of preparing the power supply network 102, it is not necessary to connect the second end 312 of the first rib 31 to the second grounding cover plate 2 by welding or other methods. At the same time, it is not necessary to connect the fourth end 322 of the second rib 32 to the first grounding cover plate 1 by welding or other methods, thereby further reducing the requirements of the preparation process. It can also further save the preparation material of the first isolation rib 3, which is more conducive to the lightweight design of the power supply network 102 and reduces the cost.

[0100] As shown in Figure 7, the first rib 31 on the first grounding cover plate 1 can be integrally formed with the first grounding cover plate 1, and the second rib 32 on the second grounding cover plate 2 can be integrally formed with the second grounding cover plate 2. Specifically, they can be integrally formed by extrusion molding or other methods to further reduce the manufacturing difficulty of the power supply network 102, facilitate the mass production of the power supply network 102, and save manufacturing costs. In some other embodiments, the first rib 31, the second rib 32, the first grounding cover plate 1, and the second grounding cover plate 2 can all be manufactured separately, so that the first rib 31 is set on the first grounding cover plate 1 by welding or riveting, and the second rib 32 is set on the second grounding cover plate 2 by welding or riveting, so as to further improve the design freedom of the power supply network 102 and meet the path design requirements of different transmission lines 4. The specific settings can be set according to actual needs and are not limited here.

[0101] Furthermore, as shown in Figure 7, along the first direction Z of the power supply network 102, the second rib 32 and the first rib 31 are spaced apart. Thus, when the first grounding cover plate 1 and the second grounding cover plate 2 are connected, the second rib 32 and the first rib 31 do not need to be aligned, which improves the fault tolerance and preparation yield in the preparation process. It also eliminates the need for welding or other connection methods, further reducing the preparation process requirements of the power supply network 102, improving the preparation efficiency of the power supply network 102, and reducing the preparation cost.

[0102] In addition, in some embodiments, along the first direction Z of the power supply network 102, the spacing between the second rib 32 and the first rib 31 can facilitate the passage of the connection segment of the transmission line 4 connecting the two transmission lines 41, without the need to set additional clearance slots or other clearance structures on the first rib 31 and the second rib 32, which can improve the wiring flexibility.

[0103] As shown in Figure 7, along the second direction X of the feed network 102, first connecting protrusions 11 are provided on opposite sides of the first grounding cover plate 1, and second connecting protrusions 21 are provided on opposite sides of the second grounding cover plate 2. Along the first direction Z, the first connecting protrusions 11 protrude from the surface of the first grounding cover plate 1, and the second connecting protrusions 21 protrude from the surface of the second grounding cover plate 2. The first grounding cover plate 1 and the second grounding cover plate 2 are electrically connected through the first connecting protrusions 11 and the second connecting protrusions 21, facilitating the formation of a transmission cavity 8 by the first grounding cover plate 1 and the second grounding cover plate 2. This structure is simple and easy to manufacture, ensuring that the transmission cavity 8 can provide good electromagnetic shielding, reducing interference from external electromagnetic fields on the feed network 102, and preventing electromagnetic radiation generated by the feed network 102 from affecting external equipment, thus ensuring the stability and accuracy of radio frequency signal transmission in the feed network 102.

[0104] Specifically, the first connecting protrusion 11 and the second connecting protrusion 21 can be connected by riveting or welding, or they can be electrically connected by other means, which is not limited here.

[0105] For example, as shown in FIG7, along the first direction Z of the power supply network 102, the first connecting protrusion 11 and the second connecting protrusion 21 can be partially connected by spot welding or other means, so that at least part of the first connecting protrusion 11 and the second connecting protrusion 21 have a gap, which can ensure the electromagnetic shielding function of the transmission cavity 8, while further reducing the manufacturing process requirements, improving the manufacturing efficiency of the power supply network 102, and reducing the manufacturing cost.

[0106] The gap between the first connecting protrusion 11 and the second connecting protrusion 21 can be set according to actual needs, as long as the radio frequency signal is not radiated out from the transmission cavity 8, and there is no restriction here.

[0107] For example, please refer to Figure 8a, which is a cross-sectional schematic diagram of the power supply network provided in this application embodiment in another specific embodiment. Along the first direction Z of the power supply network 102, the first connecting protrusion 11 and the second connecting protrusion 21 can be fully connected to further enhance the electromagnetic shielding function of the transmission cavity 8 and ensure the stability and accuracy of radio frequency signal transmission in the power supply network 102.

[0108] In one specific embodiment, as shown in FIG7, along the first direction Z of the power supply network 102, the projection of the first rib 31 and the projection of the second rib 32 at least partially overlap, thereby reducing the space occupied by the corresponding first rib 31 and second rib 32 in the second direction X, which is beneficial to reducing the spacing between two adjacent transmission segments 41 and reducing the size of the power supply network 102.

[0109] In another specific embodiment, as shown in FIG8a, the first rib 31 and the second rib 32 are spaced apart along the second direction X of the power supply network 102, thereby further improving the fault tolerance during the fabrication process and increasing the design freedom of the power supply network 102. The second direction X intersects the first direction Z.

[0110] In one specific embodiment, as shown in FIG8a, along the first direction Z, the height dimension of the first rib 31 is h1, the height dimension of the second rib 32 is h2, and the height dimension of the transmission cavity 8 is H.

[0111] Specifically, the height h1 of the first rib 31 and the height H of the transmission cavity 8 satisfy the condition 0.05H ≤ h1 < H. For example, h1 can be 0.05H, 0.1H, 0.2H, 0.3H, 0.4H, 0.5H, 0.6H, 0.7H, 0.8H, 0.9H, etc. Of course, the height h1 of the first rib 31 can also be other values ​​within the above range. It can be set according to actual needs and is not limited here. Specifically, when the height h1 of the first rib 31 and the height H of the transmission cavity 8 satisfy 0.05H ≤ h1 < H, it can be ensured that there is a gap between the first rib 31 and the second grounding cover plate 2.

[0112] The height h2 of the second rib 32 and the height H of the transmission cavity 8 satisfy 0.05H ≤ h2 < H to ensure a gap between the first rib 31 and the second grounding cover 2. For example, h2 can be 0.05H, 0.1H, 0.2H, 0.3H, 0.4H, 0.5H, 0.6H, 0.7H, 0.8H, 0.9H, etc. Of course, the height h2 of the second rib 32 can also be other values ​​within the above range. It can be set according to actual needs and is not limited here. Specifically, when the height h2 of the second rib 32 and the height H of the transmission cavity 8 satisfy 0.05H ≤ h2 < H, a gap can be ensured between the second rib 32 and the first grounding cover 1.

[0113] In addition, the height dimensions of the first rib 31 and the second rib 32 along the first direction Z of the feed network 102 can be set differently. Specifically, they can be set according to actual needs to further improve the design freedom of the feed network 102 and meet the transmission requirements of radio frequency signals at different operating frequencies. No restrictions are imposed here.

[0114] As shown in Figure 8a, in one specific embodiment, along the second direction X of the feed network 102, the spacing d between the transmission segment 41 and the first isolation rib 3 is greater than or equal to 0.01λ0, where λ0 is the wavelength corresponding to the operating frequency of the transmission segment 41. For example, the spacing between the transmission segment 41 and the first isolation rib 3 can be 0.01λ0, 0.02λ0, 0.03λ0, 0.04λ0, 0.05λ0, 0.06λ0, 0.07λ0, 0.08λ0, 0.09λ0, 0.1λ0, etc., and can be set according to actual needs, without limitation here.

[0115] In this embodiment, the distance d between the transmission segment 41 and the first isolation rib 3 easily affects the impedance and signal attenuation of the transmission line 4. The smaller d is, the greater the loss and attenuation of the transmission segment 41, and the lower the impedance. Therefore, when the distance d between the transmission segment 41 and the first isolation rib 3 is greater than or equal to 0.01λ0, the loss and signal attenuation of the transmission segment 41 can be reduced, and impedance matching of the transmission segment 41 can be easily achieved, reducing the difficulty of fabricating the transmission line 41 and ensuring the signal transmission efficiency and transmission quality of the transmission line 4.

[0116] As shown in Figure 8a, the distance d between the first rib 31 and the second rib 32 and the transmission segment 41 along the second direction X of the feed network 102 can be set differently. Specifically, it can be set according to actual needs to further improve the design freedom of the feed network 102 and meet the transmission requirements of radio frequency signals at different operating frequencies. No restrictions are imposed here.

[0117] In another specific embodiment, please refer to Figure 8b, which is a cross-sectional schematic diagram of the power supply network provided in this application embodiment in another specific embodiment. As shown in Figure 8b, along the second direction X of the power supply network 102, the first rib 31 and the second rib 32 are arranged alternately, and the transmission segment 41 is disposed between two adjacent first ribs 31 and second ribs 32. The second direction X intersects the first direction Z.

[0118] In this embodiment, as shown in Figure 8b, only a first rib 31 or a second rib 32 is provided between two adjacent transmission segments 41. This improves the inter-line isolation between each transmission segment 41 of the transmission line 4, while also further reducing the space occupied by the first rib 31 and the second rib 32 between two adjacent transmission segments 41. This helps to reduce the spacing between two adjacent transmission segments and decrease the size of the feed network. In addition, when the first grounding cover plate 1 and the second grounding cover plate 2 are connected, the second rib 32 and the first rib 31 do not need to be aligned, which improves the fault tolerance and manufacturing yield during the manufacturing process. It also eliminates the need for welding or other connection methods, further reducing the manufacturing process requirements of the feed network 102, improving the manufacturing efficiency of the feed network 102, and reducing the manufacturing cost.

[0119] In this arrangement, the first ribs 31 and the second ribs 32 are staggered, as shown in Figure 8b, where there is one second rib 32 between two adjacent first ribs 31 and one first rib 31 between two adjacent second ribs 32, i.e., the ratio of the number of first ribs 31 to the number of second ribs 32 is 1:1. It is understood that in other embodiments where the first ribs 31 and the second ribs 32 are staggered, the ratio of the number of first ribs 31 to the number of second ribs 32 can be other values; there can be fewer or more second ribs 32 between two adjacent first ribs 31, or fewer or more first ribs 31 between two adjacent second ribs 32. For example, the staggered arrangement of the first ribs 31 and the second ribs 32 can be a sequence of first rib 31, second rib 32, second rib 32, first rib 31, first rib 31, first rib 31, second rib 32.

[0120] The height dimensions of the first rib 31 and the second rib 32 along the first direction Z of the feed network 102 can be set differently, as long as there is a gap between the first rib 31 and the second grounding cover plate 2, and a gap between the second rib 32 and the first grounding cover plate 1. The specific settings can be made according to actual needs to further improve the design freedom of the feed network 102 and meet the transmission requirements of radio frequency signals at different operating frequencies. No restrictions are imposed here.

[0121] Please refer to Figures 9 and 10. Figure 9 shows the magnetic field distribution of a single transmission segment in a feed network without a first isolation rib, and Figure 10 shows the magnetic field distribution of a single transmission segment in a feed network with a first isolation rib provided in this embodiment. Compared to the feed network without a first isolation rib in Figure 9, as shown in Figure 10, the first isolation rib 3 provided in the feed network 102 provided in this embodiment can prevent electromagnetic interference between the radio frequency signals of two adjacent transmission segments 41, ensuring the independent propagation and integrity of the radio frequency signals of each transmission segment 41 of the transmission line 4, improving the inter-line isolation between each transmission segment 41 of the transmission line 4, and improving the transmission efficiency and quality of the radio frequency signals. Therefore, the feed network 102 provided in this embodiment is beneficial to reducing the spacing between two adjacent transmission segments 41, thereby reducing the size of the feed network 102.

[0122] Please refer to Figure 11, which shows a simulation curve of the inter-line isolation of a transmission line in a feeder network without a first insulating rib in a specific embodiment. In Figure 11, the horizontal axis represents frequency in GHz, where the frequency range can be 1.7GHz–2.7GHz, 0.69GHz–0.96GHz, 3.3GHz–3.8GHz, etc. For example, F1, F2, F3, F4, F5, and F6 on the horizontal axis can be 3.3GHz, 3.4GHz, 3.5GHz, 3.6GHz, 3.7GHz, and 3.8GHz respectively. The vertical axis represents the inter-line isolation in dB. As shown in Figure 11, the curves illustrate the energy transfer from the reference port to other ports. It can be seen from Figure 11 that the minimum inter-line isolation between transmission segments of the feeder network without a first insulating rib is 20dB.

[0123] Please refer to Figure 12, which shows a simulation curve of the inter-line isolation of the transmission line of the power supply network with a first isolation rib provided in an embodiment of this application in a specific embodiment. In Figure 12, the horizontal axis represents frequency in GHz, where the frequency range can be 1.7GHz~2.7GHz, 0.69GHz~0.96GHz, 3.3GHz~3.8GHz, etc. For example, F1, F2, F3, F4, F5, and F6 on the horizontal axis can be 3.3GHz, 3.4GHz, 3.5GHz, 3.6GHz, 3.7GHz, and 3.8GHz respectively; the vertical axis represents the inter-line isolation in dB. As shown in Figure 12, the curves in the figure illustrate the energy transmission from the reference port to other ports of the transmission line 4 of the power supply network 102 provided in this application. It can be seen from Figure 12 that, under the same conditions, the minimum inter-line isolation between the transmission segments 41 of the transmission line 4 of the power supply network 102 provided in this application is 38dB. Compared with the power supply network in Figure 11 that does not have a first isolation rib, the minimum inter-line isolation between the transmission segments 41 of the transmission line 4 of the power supply network 102 in this embodiment is improved by 18dB.

[0124] For example, a 1to2 power divider is used as the power supply network. Please refer to Figure 13, which is a simulation characteristic curve of a 1to2 power divider without a first isolation rib in a specific embodiment. In Figure 13, the horizontal axis represents frequency in GHz, where the frequency range can be 1.7GHz~2.7GHz, 0.69GHz~0.96GHz, 3.3GHz~3.8GHz, etc. For example, F1, F2, F3, F4, and F5 on the horizontal axis can be 3.3GHz, 3.4GHz, 3.5GHz, 3.6GHz, and 3.7GHz respectively; the vertical axis represents scattering parameters in dB. In Figure 13, curve a is the S21 parameter curve, representing the transmission coefficient from the input port to the first output port, indicating the power distribution from the input port to the first output port; curve b is the S31 parameter curve, representing the transmission coefficient from the input port to the second output port, also indicating the power distribution from the input port to the second output port; curve c is the S11 parameter curve, representing the reflection coefficient, indicating the reflection at the input port and reflecting the matching performance of the input port. As can be seen from Figure 13, the difference between curves a and b is 0.4, indicating uneven energy distribution and a large energy difference between the two transmission paths of the transmission line, resulting in poor power distribution. Curve c shows an increasing trend, indicating poor input port matching in this frequency range, which is not conducive to effectively distributing power to the two output ports and is detrimental to improving the transmission efficiency of the RF signal.

[0125] Please refer to Figure 14, which is a simulation characteristic curve of a 1to2 power divider with a first isolation rib provided in an embodiment of this application in a specific embodiment. In Figure 14, the horizontal axis represents frequency in GHz, where the frequency range can be 1.7GHz~2.7GHz, 0.69GHz~0.96GHz, 3.3GHz~3.8GHz, etc. For example, F1, F2, F3, F4, and F5 on the horizontal axis can be 3.3GHz, 3.4GHz, 3.5GHz, 3.6GHz, and 3.7GHz respectively; the vertical axis represents scattering parameters in dB. In Figure 14, curve d is the S21 parameter curve, which is the transmission coefficient from the input port to the first output port, representing the power distribution from the input port to the first output port; curve e is the S31 parameter curve, which is the transmission coefficient from the input port to the second output port, representing the power distribution from the input port to the second output port; curve f is the S11 parameter curve, which is the reflection coefficient, representing the reflection of the input port, and can reflect the matching performance of the input port. As shown in Figure 14, the difference between curve d and curve e is 0.05, indicating that the energy distribution of the two transmission paths of transmission line 4 is relatively uniform with small energy differences, resulting in good power distribution. Curve f tends to be stable, indicating that the input port is relatively stable within this frequency range, which facilitates subsequent impedance matching and helps to effectively distribute power to the two output ports, thereby improving the transmission efficiency of the RF signal.

[0126] Please refer to Figure 15, which is a schematic diagram of a power supply network structure in the related art. In Figure 15(a), the transmission line of the power supply network is a microstrip line 3' structure. In this structure, the strip conductor transmission line 31' is disposed on the upper surface of the dielectric substrate 32', and a ground plane 33' is disposed below the dielectric substrate 32'. In Figure 15(b), the transmission line of the power supply network is an inverted microstrip line 4' structure. In this structure, the strip conductor transmission line 41' is disposed on the lower surface of the dielectric substrate 42', and ground planes 43' are spaced apart below it. In Figure 15(c), the transmission line of the power supply network is a conventional strip line 5' structure without isolation ribs. This structure consists of a strip conductor transmission line 51' sandwiched between two parallel ground planes 53'.

[0127] Please refer to Figure 16, which is a simulation curve of the line-to-line isolation of the transmission lines in the feeder network. In Figure 16, the horizontal axis represents the line-edge spacing distance between two adjacent transmission segments of the transmission line, i.e., n in Figure 15, in mm, and the vertical axis represents the line-to-line isolation, in dB. In Figure 16, curve h represents the line-to-line isolation curve of transmission line 31' in Figure 15(a), curve j represents the line-to-line isolation curve of transmission line 41' in Figure 15(b), curve k represents the line-to-line isolation curve of transmission line 51' in Figure 15(c), and curve m represents the line-to-line isolation curve of transmission line 4 in the feeder network provided in this embodiment.

[0128] As shown in Figure 15, under the same conditions, i.e., when the line-side spacing n of two adjacent transmission segments is the same in each embodiment, it can be seen from Figure 16 that the line-to-line isolation of the m curve is higher, that is, the line-to-line isolation of the feeder network provided in this application embodiment is higher. Therefore, under the same line-to-line isolation requirement, using the feeder network 102 provided in this application embodiment can make the line-side spacing between each transmission segment 41 of the transmission line 4 smaller, which is beneficial to reducing the overall size of the feeder network 102.

[0129] Please refer to Figure 17, which is a partial structural exploded view of the power supply network provided in another specific embodiment of this application.

[0130] As shown in Figure 17, in one specific embodiment, the power supply network 102 further includes a first support member 7a and a second support member 7b. The first support member 7a is disposed between the transmission line 4 and the first grounding cover plate 1, and the second support member 7b is disposed between the transmission line 4 and the second grounding cover plate 2.

[0131] Please also refer to Figure 18, which is a cross-sectional view of the feed network in Figure 17 along the AA direction. As shown in Figure 18, the first support member 7a and the second support member 7b provide good support for the transmission line 4, thereby ensuring that there is a certain distance between the transmission line 4 and the first grounding cover plate 1 and the second grounding cover plate 2, avoiding short circuits caused by contact between the transmission line 4 and the first grounding cover plate 1 and the second grounding cover plate 2, ensuring reliable transmission of radio frequency signals, and also improving the structural stability of the feed network 102.

[0132] The first support member 7a and the second support member 7b are made of insulating material. Specifically, the first support member 7a and the second support member 7b can be made of epoxy resin or polytetrafluoroethylene (PTFE) and other polymer materials. The specific materials can be set according to actual needs and are not limited here.

[0133] Further, please refer to Figure 19, which is a partial structural exploded view of the power supply network provided in another specific embodiment of this application.

[0134] As shown in Figure 19, one of the first support member 7a and the second support member 7b is provided with a connecting post 71, and the other of the first support member 7a and the second support member 7b is provided with a connecting hole 72. The connecting post 71 is connected to the connecting hole 72, so that the first support member 7a and the second support member 7b can be fixed on opposite sides of the transmission line 4 along the first direction Z. This can further improve the structural stability of the feed network 102, which is beneficial to the stable transmission of radio frequency signals and ensures the transmission quality of radio frequency signals. In addition, the fact that the first support member 7a and the second support member 7b can be fixed on opposite sides of the transmission line 4 along the first direction Z also facilitates the assembly of the feed network 102 and can further improve the fabrication efficiency of the feed network 102.

[0135] The connecting post 71 and the connecting hole 72 can be connected by means of threaded connection, snap-fit, etc., to improve the connection reliability between the connecting post 71 and the connecting hole 72.

[0136] For example, in the specific embodiment shown in FIG19, the first support member 7a may be provided with a connecting hole 72, and the second support member 7b may be provided with a connecting post 71; for example, the first support member 7a may be provided with a connecting post 71, and the second support member 7b may be provided with a connecting hole 72. The specific configuration can be made according to actual needs, and no limitation is made here.

[0137] Furthermore, one or more connecting posts 71 can be provided, and one or more connecting holes 72 can also be provided accordingly, to further enhance the design freedom of the power supply network 102. The specific configuration can be determined according to actual needs and is not limited here. For example, in the specific embodiment shown in FIG19, a connecting hole 72 can be provided on the first support member 7a, and a connecting post 71 can be provided on the second support member 7b, to reduce the structural complexity of the power supply network 102, facilitate the fabrication of the power supply network 102, further improve the fabrication efficiency of the power supply network 102, and save fabrication costs.

[0138] Furthermore, as shown in Figure 19, a second through hole 43 can be provided on the transmission line 4. The connecting post 71 passes through the second through hole 43 and connects to the connecting hole 72, thereby limiting the displacement of the first support member 7a and the second support member 7b on the transmission line 4. This further improves the fixing effect of the first support member 7a and the second support member 7b on the transmission line 4, thereby further improving the structural stability of the power supply network 102.

[0139] As shown in Figure 19, the transmission segment 41 of the transmission line 4 includes a first segment 411 and a second segment 412 connected to each other. A first support member 7a and a second support member 7b are disposed on the second segment 412. Along the second direction X of the feed network 102, the width of the second segment 412 is less than or equal to the width of the first segment 411. The second direction X intersects with the first direction Z.

[0140] Since the first support member 7a and the second support member 7b are made of insulating materials with a large dielectric constant, when the first support member 7a and the second support member 7b are placed on the transmission line 4, the distribution of the electric field on the first support member 7a and the second support member 7b changes. This easily leads to an increase in the equivalent capacitance on the transmission line 4, thereby reducing the characteristic impedance of the transmission line. The thinner the transmission line 4, the lower the equivalent capacitance and the higher the impedance.

[0141] Therefore, as shown in Figure 19, when the width of the second segment 412 is less than or equal to the width of the first segment 411, the equivalent capacitance of the second segment 412, i.e. the capacitance between the second segment 412 and the first grounding cover 1 and the second grounding cover 2, can be reduced, thereby increasing the impedance of the second segment 412. This reduces the influence of the first support member 7a and the second support member 7b on the impedance of the second segment 412 and ensures the transmission performance of the radio frequency signal.

[0142] In particular, along the second direction X of the power supply network 102, the width of the second segment 412 and the width of the first segment 411 can be set according to actual needs, and are not limited here.

[0143] Please refer to Figure 20, which is a partial structural exploded view of the power supply network provided in another specific embodiment of this application.

[0144] As shown in Figure 20, the transmission line 4 also includes multiple connecting segments 42. The extension direction of the connecting segments 42 intersects the extension direction of the transmission segments 41. One end of the connecting segment 42 is connected to one transmission segment 41, and the other end of the connecting segment 42 is connected to another transmission segment 41, so that the multiple transmission segments 41 are electrically connected, which meets the signal transmission path design requirements from the input port to each output port of the power supply network 102 and facilitates the transmission of radio frequency signals.

[0145] The transmission segment 41 can extend along a third direction Y of the power supply network 102, and the connecting segment 42 can extend along a second direction X of the power supply network 102, with an angle between the second direction X and the third direction Y. For example, the second direction X can be the width direction of the power supply network 102, and the third direction Y can be the length direction of the power supply network 102, so that the transmission segment 41 and the connecting segment 42 are approximately perpendicular to each other, in order to meet the transmission path design requirements of the power supply network 102. Of course, the transmission segment 41 and the connecting segment 42 can also be curved structures to improve the design freedom of the power supply network. The specific design can be determined according to actual needs, as long as the connecting segment 42 can connect the two transmission segments 41; no restrictions are imposed here.

[0146] Please refer to Figure 21, which is a magnified view of part I in Figure 20.

[0147] As shown in Figure 21, in one specific embodiment, a clearance groove 33 is provided on the first isolation rib 3. Along the first direction Z, the connecting segment 412 is located above the clearance groove 33, or the connecting segment 412 passes through the clearance groove 33, thereby preventing the connecting segment 42 from contacting the first isolation rib 3, further reducing the short-circuit risk of the transmission line 4, and ensuring reliable transmission of radio frequency signals. Furthermore, this structure is simple, easy to fabricate, and can further reduce the structural complexity of the feed network 102, saving fabrication costs.

[0148] For example, the connecting segment 42 can be fixed above the clearance groove 33 to further prevent the connecting segment 42 from contacting the first isolation rib 3, thereby further reducing the short-circuit risk of the transmission line 4. For example, the connecting segment 42 can also pass through the clearance groove 33 to further reduce the size of the power supply network 102 in the first direction Z, which is beneficial to the miniaturization design of the power supply network 102.

[0149] As shown in Figure 21, along the first direction of the power supply network 102, a first support member 7a and a second support member 7b can be provided on opposite sides of the connecting section 42 so that the connecting section 42 can be fixed above the clearance groove 33, thereby further improving the structural stability of the power supply network 102.

[0150] Please refer to Figures 22 and 23. Figure 22 is a partial structural exploded view of the power supply network provided in another specific embodiment of this application; Figure 23 is a partial enlarged view of point II in Figure 22.

[0151] As shown in Figure 23, in one specific embodiment, the power supply network 102 further includes a second isolation rib 5. The second isolation rib 5 is disposed at least in one of the first grounding cover plate 1 and the second grounding cover plate 2. The extension direction of the second isolation rib 5 intersects the extension direction of the first isolation rib 3. Along the first direction of the power supply network 102, the projection of the second isolation rib 5 is located between two adjacent connecting segments 42.

[0152] In this embodiment, as shown in FIG23, the provision of the second isolation rib 5 can improve the line isolation between two adjacent connection segments 42, thereby further improving the transmission efficiency and quality of radio frequency signals. This is beneficial for reducing the spacing between two adjacent transmission segments 41, thus reducing the size of the feed network 102. In addition, through the cooperation of the second isolation rib 5 and the first isolation rib 3, the corresponding second isolation rib 5 and the first isolation rib 3 can be set at the required positions according to the routing requirements of the transmission line 4. This can further improve the line isolation of the transmission line 4, while also further reducing the material used in the first isolation rib 3, which is beneficial for the lightweight design of the feed network and saves manufacturing costs.

[0153] The first isolation rib 3 can extend along a third direction Y of the feeder network 102, and the second isolation rib 5 can extend along a second direction X of the feeder network 102, with an angle between the second direction X and the third direction Y. For example, the second direction X can be the width direction of the feeder network 102, and the third direction Y can be the length direction of the feeder network 102, so that the first isolation rib 3 and the second isolation rib 5 are approximately perpendicular to each other, in order to meet the transmission path design requirements of the feeder network 102. Of course, the first isolation rib 3 and the second isolation rib 5 can also be curved structures to increase the design freedom of the feeder network 102; the specific design can be set according to actual needs and is not limited here.

[0154] In one specific embodiment, when the second isolation rib 5 is disposed on the first grounding cover plate 1, the end of the second isolation rib 5 away from the first grounding cover plate 1 is spaced apart from the second grounding cover plate. When the second isolation rib 5 is disposed on the second grounding cover plate 2, the end of the second isolation rib 5 away from the second grounding cover plate 2 is spaced apart from the first grounding cover plate 1. Thus, in the process of preparing the power supply network 102, it is not necessary to connect the second isolation rib 5 disposed on the first grounding cover plate 1 to the second grounding cover plate 2 by welding or other means, nor is it necessary to connect the second isolation rib 5 disposed on the second grounding cover plate 2 to the first grounding cover plate 1 by welding or other means, thereby further reducing the requirements of the preparation process.

[0155] Furthermore, along the first direction Z of the power supply network 102, the second isolation ribs 5 disposed on the first grounding cover plate 1 and the second isolation ribs 5 disposed on the second grounding cover plate 2 are spaced apart. Thus, when the first grounding cover plate 1 and the second grounding cover plate 2 are connected, the two second isolation ribs 5 do not need to be aligned, which improves the fault tolerance and manufacturing yield in the manufacturing process. It also eliminates the need for welding or other connection methods, further reducing the manufacturing process requirements of the power supply network 102, improving the manufacturing efficiency of the power supply network 102, and reducing the manufacturing cost.

[0156] In one specific embodiment, along the first direction Z of the power supply network 102, the projection of the second isolation rib 5 disposed on the first grounding cover plate 1 at least partially overlaps with the projection of the second isolation rib 5 disposed on the second grounding cover plate 2, thereby reducing the space occupied by the second isolation rib 5, which is beneficial to reducing the spacing between two adjacent connection segments 42 and reducing the size of the power supply network 102.

[0157] In another specific embodiment, along the third direction Y of the power supply network 102, the second isolation rib 5 placed on the first grounding cover plate 1 is spaced apart from the second isolation rib 5 placed on the second grounding cover plate 2, thereby further improving the fault tolerance rate in the manufacturing process and improving the design freedom of the power supply network 102.

[0158] The height of the second isolation rib 5 on the first grounding cover plate 1 and the second isolation rib 5 on the second grounding cover plate 2 along the first direction Z of the feed network 102 can be set differently. Specifically, it can be set according to actual needs to further improve the design freedom of the feed network 102 and meet the transmission requirements of radio frequency signals at different operating frequencies. No restrictions are imposed here.

[0159] Specifically, the height of the second isolation rib 5 can be the same as the height of the first isolation rib 3 set on the same grounding cover plate. Of course, the height of the second isolation rib 5 can also be different from the height of the first isolation rib 3. The specific setting can be made according to actual needs, and there is no restriction here.

[0160] Furthermore, the second isolation rib 5 disposed on the first grounding cover plate 1 can be integrally formed with the first grounding cover plate 1, and the second isolation rib 5 disposed on the second grounding cover plate 1 can be integrally formed with the second grounding cover plate 2, so as to further reduce the manufacturing difficulty of the feeder network 102, facilitate the mass production of the feeder network 102, and save manufacturing costs. In some other embodiments, the second isolation rib 5, the first grounding cover plate 1, and the second grounding cover plate 2 can all be manufactured separately, so that the second isolation rib 5 is disposed on the first grounding cover plate 1 and / or the second grounding cover plate 2 by welding or riveting, so as to further improve the design freedom of the feeder network 102 and meet the path design requirements of different transmission lines 4. The specific configuration can be set according to actual needs and is not limited here.

[0161] Please refer to Figure 24, which is a partial structural exploded view of the power supply network provided in the application embodiment in another specific embodiment.

[0162] In one specific embodiment, as shown in FIG24, the power supply network 102 further includes an insulating member 6, which is connected to the first isolation rib 3 and the transmission line 4 respectively, so that the transmission line 4 and the first isolation rib 3 are spaced apart, thereby avoiding contact between the transmission line 4 and the first isolation rib 3, further reducing the short-circuit risk of the transmission line 4, and ensuring reliable transmission of radio frequency signals. Moreover, the structure is simple and easy to implement, and it can further improve the support and fixation effect on the transmission line 4, thereby further improving the structural stability of the power supply network 102.

[0163] Please refer to Figure 25, which is a cross-sectional view of the feeder network in Figure 24 along the BB direction.

[0164] In one specific embodiment, as shown in FIG25, the insulating element 6 is disposed between the connecting section 42 of the transmission line 4 and the first isolation rib 3, so as to further reduce the material used in the preparation of the insulating element 6, which is beneficial to the lightweight design of the power supply network 102 and saves the manufacturing cost.

[0165] The insulating component 6 can be a sheet-like structure such as an insulating film or insulating sheet, or a block-like structure such as an insulating medium bead. The specific configuration can be determined according to actual needs and is not limited here. Specifically, as shown in Figure 25, multiple insulating components 6 can be provided. Some insulating components 6 are located between the connecting section 42 and the first rib 31, while other insulating components 6 are located between the connecting section 42 and the second rib 32. This enhances the support and fixation effect on the transmission line 4, thereby further improving the structural stability of the power supply network 102.

[0166] Please refer to Figure 26, which is an exploded schematic diagram of the power supply network provided in the embodiment of this application in another specific embodiment.

[0167] In another specific embodiment, as shown in Figure 26, the insulating component 6 is provided with multiple first through holes 61 to form a porous mesh structure, thereby reducing the weight of the insulating component 6. This facilitates the lightweight design of the power supply network 102, saves costs, and also reduces the contact area between the insulating component 6 and the transmission line 4, reducing the impact on the impedance and loss of the transmission line 4 and improving the transmission performance of the radio frequency signal. In addition, the insulating component 6 has a good insulation and support effect on the transmission line 4, which can prevent the transmission line 4 from contacting and connecting with grounding components such as the first grounding cover plate 1, the second grounding cover plate 2, the first isolation rib 3, and the second isolation rib 5, further reducing the short-circuit risk of the transmission line 4 and ensuring reliable transmission of radio frequency signals. Moreover, there is no need to set up additional support components, which can reduce the use of parts and further save manufacturing costs.

[0168] As shown in Figure 26, the first through-hole 61 can penetrate the insulating member 6 along the first direction Z, or along a direction that forms an angle with the plane formed by the second direction X and the third direction Y. The first through-hole 61 can be a hexagonal through-hole, so that the insulating member 6 forms a honeycomb mesh structure, such as a paper honeycomb or foamed honeycomb structure, to further improve the structural strength of the insulating member 6, thereby improving the support effect of the insulating member 6 on the transmission line 4, further improving the structural stability of the feed network 102, and ensuring reliable transmission of radio frequency signals. Of course, in some other embodiments, the first through-hole 61 can also be a circular through-hole, a square through-hole, a triangular through-hole, or other irregularly shaped through-holes, etc., which can be set according to actual needs and are not limited here.

[0169] In other specific embodiments, the insulating element 6 can also be an insulating dielectric plate or an insulating dielectric support frame. Of course, the insulating element 6 can also be a dielectric material structure filled in the transmission cavity 8 or an in-mold injection structure, etc., to improve the design freedom of the power supply network 102. The insulating element 6 can be set according to actual needs, and there are no restrictions here.

[0170] Please refer to Figure 27, which is a cross-sectional schematic diagram of the power supply network provided in the embodiment of this application in another specific embodiment.

[0171] As shown in Figure 27, in one specific embodiment, the power supply network 102 further includes a third grounding cover plate 9, which is disposed between the first grounding cover plate 1 and the second grounding cover plate 2 to divide the transmission cavity 8 into a first transmission cavity 81 and a second transmission cavity 82 arranged along the first direction Z. Specifically, the first grounding cover plate 1 and the third grounding cover plate 9 surround to form the first transmission cavity 81, and the third grounding cover plate 9 and the second grounding cover plate 2 surround to form the second transmission cavity 82.

[0172] The power supply network 102 includes a first transmission line 4a and a second transmission line 4b. The first transmission line 4a is disposed in a first transmission cavity 81, and the second transmission line 4b is disposed in a second transmission cavity 82. The first isolation rib 3 also includes a third rib 34. Along the first direction Z of the power supply network 102, at least one side of the third grounding cover plate 9 is provided with a third rib 34, and at least a portion of the projection of the third rib 34 is located between two adjacent transmission segments 41 of the first transmission line 4a and / or two adjacent transmission segments 41 of the second transmission line 4b, forming a multi-layered power supply network 102 structure. This facilitates the stacking of multiple transmission lines 4, further improving the design freedom and integration of the power supply network 102.

[0173] In one specific embodiment, as shown in FIG27, the end of the third rib 34 away from the third grounding cover plate 9 is spaced apart from the first grounding cover plate 1 and / or the second grounding cover plate 2. Thus, in the process of preparing the power supply network 102, it is not necessary to connect the third rib 34 on the third grounding cover plate 9 to the first grounding cover plate 1 and / or the second grounding cover plate 2 by welding or other means, thereby further reducing the requirements of the preparation process.

[0174] Furthermore, as shown in Figure 27, along the first direction Z of the power supply network 102, the third rib 34 is spaced apart from the first rib 31 and / or the second rib 32. Thus, when the third grounding cover plate 9 is connected to the first grounding cover plate 1 and the second grounding cover plate 2 respectively, the third rib 34 does not need to be aligned with the first rib 34 and / or the second rib 32, which improves the fault tolerance and preparation yield in the preparation process. It also eliminates the need for welding or other connection methods, further reducing the preparation process requirements of the power supply network 102, improving the preparation efficiency of the power supply network 102, and reducing the preparation cost.

[0175] In one specific embodiment, along the first direction Z of the power supply network 102, the projection of the third rib 34 at least partially overlaps with the projection of the first rib 31 and / or the projection of the second rib 32, thereby reducing the space occupied by the first isolation rib 3, which is beneficial to reducing the spacing between two adjacent transmission segments 41 and reducing the size of the power supply network 102.

[0176] In another specific embodiment, along the second direction X of the power supply network 102, the third rib 34 is spaced apart from the first rib 31 and / or the second rib 32, thereby further improving the fault tolerance during the fabrication process and increasing the design freedom of the power supply network 102.

[0177] The height dimension of the third rib 34 along the first direction Z of the feed network 102 can be different from that of the first rib 31 and the second rib 32. It can be set according to actual needs to further improve the design freedom of the feed network 102 and meet the transmission requirements of radio frequency signals at different operating frequencies. No restrictions are imposed here.

[0178] In addition, the third rib 34 can be integrally formed with the third grounding cover plate 9 to further reduce the fabrication difficulty of the feeder network 102, facilitate mass production of the feeder network 102, and save fabrication costs. In some other embodiments, the third rib 34 and the third grounding cover plate 9 can be fabricated separately, and the third rib 34 can be set on the third grounding cover plate 34 by welding or riveting, so as to further improve the design freedom of the feeder network 102 and meet the path design requirements of different transmission lines 4. The specific settings can be set according to actual needs and are not limited here.

[0179] Furthermore, as shown in Figure 27, the power supply network also includes a connector 10, which passes through the third grounding cover plate 9. One end of the connector 10 is electrically connected to the first transmission line 4a, and the other end is electrically connected to the second transmission line 4b, so that the first transmission line 4a and the second transmission line 4b are electrically connected to facilitate signal transmission between multiple transmission lines in the power supply network 102.

[0180] For example, as shown in FIG27, the connector 10 can be a connector pin, and the third grounding cover plate 9 can be provided with a through hole. After the connector 10 passes through the through hole, its two ends are welded to the first transmission line 4a and the second transmission line 4b respectively. This structure is simple and easy to implement.

[0181] Please refer to Figure 28, which is an exploded view of the power supply network provided in this application embodiment in another specific embodiment. As shown in Figure 28, along the first direction of the power supply network 102, the third grounding cover plate 9 can also be provided with second isolation ribs 5 on opposite sides to further improve the design freedom of the power supply network 102 and meet the design requirements of the power supply network 102. The specific configuration can be set according to actual needs and is not limited here.

[0182] The second isolation ribs 5 located on opposite sides of the third grounding cover plate 9 have the same structure and function as the second isolation ribs 5 located in the first grounding cover plate 1 and / or the second grounding cover plate 2 in the above embodiments. The second isolation ribs 5 can improve the line isolation between two adjacent connection segments 42, thereby further improving the transmission efficiency and quality of radio frequency signals. This is beneficial for reducing the spacing between two adjacent transmission segments 41, thus reducing the size of the feed network 102. In addition, through the cooperation of the second isolation ribs 5 and the first isolation ribs 3, the corresponding second isolation ribs 5 and the first isolation ribs 3 can be set at the required positions according to the routing requirements of the transmission line 4. This can further improve the line isolation of the transmission line 4, while also further reducing the material used in the first isolation ribs 3, which is beneficial for the lightweight design of the feed network and saves manufacturing costs.

[0183] Further, the second isolation ribs 5 disposed on opposite sides of the third grounding cover plate 9 intersect the extending direction of the first isolation rib 3. Along the first direction Z of the feed network 102, the projection of the second isolation rib 5 is located between two adjacent connecting segments 42. Along the first direction Z, the second isolation ribs 5 disposed on opposite sides of the third grounding cover plate 9 are respectively spaced apart from the second isolation ribs 5 on the first grounding cover plate 1 and / or the second grounding cover plate 2. Exemplarily, along the first direction Z of the feed network 102, the projection of the second isolation rib 5 disposed on the third grounding cover plate 9 at least partially overlaps with the projection of the second isolation rib 5 disposed on the first grounding cover plate 1 and / or the second grounding cover plate 2. Exemplarily, along the third direction Y of the feed network 102, the second isolation rib 5 disposed on the third grounding cover plate 9 is spaced apart from the second isolation rib 5 disposed on the first grounding cover plate 1 and / or the second grounding cover plate 2.

[0184] The height of the second isolation rib 5 on the third grounding cover plate 9 and the second isolation rib 5 on the first grounding cover plate 1 and / or the second grounding cover plate 2 along the first direction Z of the feed network 102 can be set differently. Specifically, it can be set according to actual needs to further improve the design freedom of the feed network 102 and meet the transmission requirements of radio frequency signals at different operating frequencies. No restrictions are imposed here.

[0185] Specifically, the height of the second isolation rib 5 can be the same as the height of the first isolation rib 3 set on the same grounding cover plate. Of course, the height of the second isolation rib 5 can also be different from the height of the first isolation rib 3. The specific setting can be made according to actual needs, and there is no restriction here.

[0186] Furthermore, the second isolation rib 5 disposed on the third grounding cover plate 9 can be integrally formed with the third grounding cover plate 1 to further reduce the fabrication difficulty of the feeder network 102, facilitate the mass production of the feeder network 102, and save fabrication costs. In some other embodiments, the second isolation rib 5 and the third grounding cover plate 9 can both be fabricated separately, so that the second isolation rib 5 is disposed on the third grounding cover plate 9 by welding or riveting, etc., to further improve the design freedom of the feeder network 102 and meet the path design requirements of different transmission lines 4. The specific configuration can be set according to actual needs and is not limited here.

[0187] In the above embodiments, the power supply network 102 provided in this application can be implemented using a printed circuit board (PCB). That is, in the process of preparing the power supply network 102, a transmission line 4 is formed by etching a strip conductor of a specific width from a copper foil or metal foil layer and sandwiching it between two insulating dielectric layers. A first grounding cover plate 1 and a second grounding cover plate 2 are then provided on the outside of the insulating dielectric layers, and corresponding first isolation ribs 3 and second isolation ribs 5 are provided on the first grounding cover plate 1 and the second grounding cover plate 2, etc., to form a power supply network structure, which is beneficial to the lightweight and integrated design of the power supply network 102.

[0188] In some other embodiments, the power supply network 102 can also be implemented by circular splicing wire or sheet metal strip wire, which can be set according to actual needs, and there are no further restrictions.

[0189] The same or similar parts between the various embodiments in this specification can be referred to mutually. In particular, the device embodiments and terminal embodiments are basically similar to the method embodiments, so the description is relatively simple, and the relevant parts can be referred to the description in the method embodiments.
