Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically to a power supply network component and antenna device. Background Technology

[0002] Typically, 5G antenna elements (also called radiating elements) are patch elements. In order to enable the antenna elements to obtain more linear amplitude and phase, ensure better radiation performance, and have good anti-interference effect, research on related feed network components has emerged.

[0003] For example, Chinese utility model patent CN115832696A, entitled "An Antenna Device and Feed Network Assembly," describes a feed network assembly comprising a dielectric substrate, a feed network layer, a ground plane, and a ground layer. The feed network layer is connected to one side of the dielectric substrate and has feed lines. On one hand, the dielectric above the feed network layer is the dielectric substrate, and below it is a cavity structure, forming an air cavity, thus giving the feed network assembly low-loss characteristics. On the other hand, this stripline structure sandwiches the feed network layer between two ground planes, making it less susceptible to external impacts and electromagnetic interference. In particular, it reduces the radiation effect from the antenna element, allowing the antenna element to achieve a more linear amplitude and phase, ensuring better radiation performance and providing good anti-interference capabilities.

[0004] Typically, the PCB board connected to the power supply network and the reflector on the filter are bonded or soldered together to form a whole. When using bonding or soldering, it is impossible to ensure that the adhesive is applied evenly, which will affect the consistency of the air height between the power supply network traces and the ground plane, thus affecting the performance of the power supply network.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem that the uneven application of adhesive during bonding or welding can affect the uniformity of air height between the feed network traces and the ground plane, thus impacting the performance of the feed network, this invention provides a feed network component and antenna device. This device enables the placement of multiple bases 400 between a PCB board 300 and a reflector 100, and the detachable connection of the PCB board 300 and the reflector 100 via multiple connectors 500. This ensures that the PCB board 300 and all bases 400 are in contact, effectively guaranteeing the height consistency between the PCB board 300 and the reflector 100 after connection. This not only enhances the connection strength but also significantly improves the performance of the feed network.

[0021] Please see Figure 1 , Figure 2 and Figure 4 , Figure 2 , Figure 4 This is a schematic diagram of a feeding network assembly and antenna device according to an embodiment of the present invention. The feeding network assembly is configured to connect to a filter. The filter includes a reflector 100. The feeding network assembly includes a feeding network layer 200, a PCB board 300, multiple bases 400, and multiple connectors 500. The PCB board 300 is spaced apart from the reflector 100, and an air gap layer is formed between the PCB board 300 and the reflector 100. The multiple bases 400 are disposed in the air gap layer and configured to connect to the reflector 100. One end of the connector 500 is connected to the PCB board 300, and the other end is detachably connected to the base 400, so that when the connector 500 is connected to the base 400, the PCB board 300 and the multiple bases 400 are all in contact.

[0022] In this device, compared to existing technologies, by placing multiple bases 400 between the PCB board 300 and the reflector 100, and detachably connecting the PCB board 300 and the reflector 100 through multiple connectors 500, the PCB board 300 and multiple bases 400 can be in contact with each other. By using multiple bases 400 with the same height, the height consistency between the PCB board 300 and the reflector 100 after connection is effectively guaranteed. This not only improves the connection strength but also effectively improves the performance of the power supply network. It solves the technical problem in existing technologies where the uniform application of adhesive during bonding or welding affects the air height consistency between the power supply network traces and the ground plane, thus affecting the performance of the power supply network.

[0023] Furthermore, the feed network layer 200 here has an air gap layer between the PCB board 300 and the reflector 100, which enables the antenna vibrator to obtain a more linear amplitude and phase, ensuring better radiation performance and good anti-interference effect. This is a conventional setting known to those skilled in the art. For reference, please refer to Chinese Utility Model Patent No. CN115832696A, entitled "An Antenna Device and Feed Network Component", which will not be described in detail here.

[0024] Furthermore, PCB board 300 here is a circuit board, which is a common and readily available device on the market and is a conventional setup known to those skilled in the art, so it will not be described in detail here.

[0025] In this embodiment, as Figure 2 , Figure 4 As shown, the base 400 has a connection hole relative to the PCB board 300, and the PCB board 300 has a through hole relative to the connection hole. The connector 500 has a large diameter section and a small diameter section. The small diameter section of the connector 500 passes through the through hole and is detachably connected to the inner wall of the connection hole. The cross-sectional area of ​​the large diameter section of the connector 500 is larger than the diameter of the through hole, and the large diameter section of the connector 500 abuts against the PCB board 300.

[0026] The connector 500 achieves a detachable connection with the PCB board 300 through a through hole. At the same time, the small diameter section of the connector 500 passes through the through hole and is detachably connected to the inner wall of the hole, while the large diameter section of the connector 500 abuts against the PCB board 300 to form a detachable connection structure.

[0027] Furthermore, by utilizing the fact that the cross-sectional area of ​​the large-diameter section of the connector 500 is larger than the diameter of the through hole, the PCB board 300 is pressed tightly onto the base 400 by the connector 500, which can effectively ensure the consistency of the connection height and improve the performance of the power supply network.

[0028] In one embodiment, the circumferential inner wall of the connecting hole is provided with an internal thread, the circumferential outer wall of the small diameter section of the connecting body 500 is provided with an external thread, and the small diameter section of the connecting body 500 is threadedly connected to the connecting hole of the base 400.

[0029] The small-diameter section of the connector 500 and the connecting hole of the base 400 are connected by a thread to achieve a detachable connection.

[0030] Furthermore, the connector 500 here is a screw or bolt that is common and readily available on the market. The threaded section of the screw or bolt passes through the through hole and is threadedly connected to the threaded hole on the base 400, and the large diameter section of the bolt or screw abuts against the PCB board 300.

[0031] In some embodiments, an elastic snap-fit ​​element can be provided on the small diameter section of the connector 500, and a slot can be provided on the inner wall of the connecting hole. The detachable connection is achieved by using the elastic snap-fit ​​element and the slot to form an elastic engagement structure. This will not be elaborated further here.

[0032] In one embodiment, please refer to Figure 2 , Figure 4 The PCB board 300 also has at least one positioning hole, and the power supply network assembly also includes at least one positioning body 600, one end of which is connected to the reflector 100 and the other end can be inserted into the positioning hole.

[0033] By setting up a structure in which positioning holes and positioning bodies 600 cooperate, the connection between the PCB and the reflector 100 is guided, thus facilitating installation by the user.

[0034] Furthermore, the positioning body 600 here is cylindrical.

[0035] In one embodiment, please refer to Figure 4 There are two positioning holes, which are spaced apart at both ends of the reflector plate 100, and the positioning body 600 is set in a one-to-one correspondence with the positioning hole.

[0036] Two positioning bodies 600 are set at intervals at both ends of the PCB board 300, which can improve the accuracy of the connection and facilitate user operation.

[0037] In one embodiment, please refer to Figure 4 Multiple bases 400 are arranged at intervals along the length and width of the reflector 100.

[0038] Multiple bases 400 and reflectors 100 are spaced apart in length and width, which can effectively control the installation distance between the PCB board 300 and the reflector 100 and effectively ensure the consistency of installation height.

[0039] In one embodiment, please refer to Figures 1 to 4 The power supply network assembly also includes two separator bars 700, which are parallel to each other and spaced apart, and are respectively connected to both sides of the reflector 100.

[0040] The separators 700 are parallel to each other and spaced apart, and are all connected to both sides of the reflector 100, which can effectively separate two adjacent power supply network components and avoid signal interference between them.

[0041] Furthermore, the setting of the separator 700 here is a conventional setting known to those skilled in the art. For reference, please refer to the Chinese utility model patent with publication number CN115832696A, entitled "An antenna device and a feed network component", which will not be described in detail here.

[0042] In one embodiment, please refer to Figure 4 The reflector 100 and the two separators 700 are an integral structure.

[0043] The reflector 100 and the two separators 700 form an integral structure, which can effectively improve the overall connection stability and connection strength.

[0044] In this embodiment, an antenna device is also provided, including a filter, at least one radiating element 800 and a feed network assembly. A reflector 100 is formed on the housing of the filter. A PCB board 300 is used to connect to the feed network layer 200, and the PCB board 300 is detachably connected to the reflector 100 via multiple bases 400. The radiating element 800 is connected to the PCB board 300 and electrically connected to the feed network layer 200.

[0045] At least one radiating element 800 is connected to the PCB board 300 and electrically connected to the feed network layer 200, thereby forming the overall structure of the antenna device.

[0046] Furthermore, the radiating element 800 here is an oscillator, which is a conventional setting known to those skilled in the art. For reference, please refer to Chinese Utility Model Patent No. CN115832696A, entitled "An Antenna Device and Feed Network Component", or Chinese Utility Model Patent No. CN216288962U, entitled "An AFU Antenna for Easy Testing". Further details will not be provided here.

[0047] Furthermore, in some embodiments, both the reflector 100 and the separator 700 are part of the filter's housing structure.

[0048] In some embodiments, the base 400 and the reflector 100 are integral structures, and the base 400 is also a housing structure of the filter, which is obtained by milling the housing of the filter, which will not be described in detail here.

[0049] Furthermore, the filter here is a cavity filter.

[0050] In one embodiment, please refer to Figure 1 , Figure 2 The antenna device also includes an antenna radome 900, which covers at least one radiating element 800.

[0051] The radome 900 is disposed over at least one radiating element 800 to form a protective structure for at least one radiating element 800.

[0052] Furthermore, the radome 900 here is a conventional configuration known to those skilled in the art, and will not be described in detail here.

[0053] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below: A plurality of bases 400 are provided on the reflector 100 connected to the filter. The PCB board 300 is spaced apart from the reflector 100 to form an air gap layer for connecting the power supply network layer 200. A plurality of connectors 500 are correspondingly provided with the plurality of bases 400, and one end of the connector 500 is connected to the PCB board 300 and the other end is detachably connected to the base 400, so that the PCB board 300 and the power supply network layer 200 are detachably connected to the reflector 100 and the PCB board 300 abuts against the plurality of bases 400. Compared to existing technologies, by placing multiple bases 400 between the PCB board 300 and the reflector 100, and detachably connecting the PCB board 300 and the reflector 100 through multiple connectors 500, the PCB board 300 and multiple bases 400 can all abut against each other. By using multiple bases 400 with the same height, the high consistency of the connection between the PCB board 300 and the reflector 100 can be effectively guaranteed. This not only improves the connection strength, but also effectively improves the performance of the power supply network.

[0054] Furthermore, in this application, the PCB board 300 is connected by a power supply network. The filter part uses the upper surface of the filter as an antenna reflector 100 and is connected to the antenna by a connector probe. The antenna reflector 100 or cavity filter surface is processed to form a certain number and height of bases 400. These bases 400 are threaded and integrally formed with the reflector 100 or filter. The bottom metal layer of the PCB board 300 with the power supply network is removed, and it is limited by the positioning body 600 on the reflector 100 and fixed to the reflector 100 or filter with screws.

[0055] Furthermore, since the PCB board 300 is fixed on the base 400, a certain height gap is formed between it and the metal reflector 100 or the filter housing surface, thus forming a new microstrip PCB board 300 with a lower dielectric constant. Compared with the traditional PCB board 300, the dielectric constant is reduced effectively and quickly, thereby reducing the loss caused by the transmission path, without increasing the cost burden, and is more convenient and faster.

[0056] This application, through the aforementioned structure, can solve the technical problem in the prior art where the inability to ensure uniform application of adhesive during bonding or welding affects the consistency of air height between the power supply network wiring and the ground plane, thereby affecting the performance of the power supply network.

[0057] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
