This invention provides a universal dielectric structure, a cavity phase shifter, and an antenna device, relating to the field of mobile communication base station antenna technology. The universal dielectric structure includes a first dielectric group, a second dielectric group, and a third dielectric group; the first dielectric group is arranged in pairs, comprising a first dielectric and a second dielectric; the second dielectric group includes a third dielectric and a fourth dielectric; the third dielectric group includes a fifth dielectric and a sixth dielectric; both the first and second dielectric groups are 1x phase-shifting dielectrics, and the third dielectric group is a 1.5x phase-shifting dielectric. The universal dielectric structure uses fewer types of phase-shifting dielectrics, requiring less mold investment and eliminating the need for frequent mold making, thus shortening the development cycle; furthermore, the phase-shifting dielectrics are standardized designs, so shifters with different power division ratios do not require redesigning the phase-shifting dielectrics, but can simply select from the standardized dielectrics, further shortening the development cycle.

Description

Technical Field

[0001] This invention relates to the field of mobile communication base station antenna technology, and in particular to a universal dielectric structure, a cavity phase shifter, and an antenna device. Background Technology

[0002] With the rapid development of mobile communication services, green antennas have become the main theme of future base station antenna technology evolution and industrial development. In order to improve antenna gain and reduce phase shifter loss, most current green antennas use short cables or cableless phase shifters. Therefore, the length of the cavity phase shifter is relatively long, resulting in a relatively long dielectric length of the phase shifter.

[0003] Since the dielectric material is generally narrow and elongated, direct molding would result in a large mold and high mold costs. Furthermore, the long length of the dielectric material makes it difficult to guarantee the forming dimensions and precision. Therefore, individual dielectric materials cannot be too long; typically, a design is adopted where the entire dielectric material is molded in segments and then assembled into a single unit. However, phase shifters with different numbers of output ports require independent dielectric structures, resulting in a large number of molds and materials, high investment costs, and long development cycles.

[0010] The first and second media groups are both one-time phase-shifting media, and the third media group is one-and-a-half-time phase-shifting media.

[0011] As a further optional solution to the general structure of the medium, the first tooth assembly includes a first tooth body and a first tooth groove, the first tooth body and the first tooth groove being arranged along the length direction of the first medium;

[0012] The second tooth assembly includes a second tooth body and a second tooth groove, the second tooth body and the second tooth groove being arranged along the length direction of the third medium;

[0019] As a further alternative to the general structure of the medium, the third medium has a second protrusion on at least one side along the width direction, and the fourth medium has a second buckle on the side facing the third medium along the thickness direction, the second buckle engaging with the second protrusion.

[0020] As a further optional embodiment of the general structure of the medium, the fifth medium has a third protrusion on at least one side along the width direction, and the sixth medium has a third buckle on the side facing the fifth medium along the thickness direction, the third buckle engaging with the third protrusion.

[0028] An antenna device includes the aforementioned cavity phase shifter.

[0029] The embodiments of the present invention have the following beneficial effects:

[0030] In the aforementioned general dielectric structure, the first dielectric groups are arranged in pairs, with the hook on the first dielectric in one first dielectric group nested with the slot on the second dielectric in the other first dielectric group, and the slot on the second dielectric in one first dielectric group nested with the hook on the first dielectric in the other first dielectric group, thereby connecting the two first dielectric groups to each other. Furthermore, since the second tooth assembly can engage with the first or second tooth assembly along its width, and the third tooth assembly can engage with the first, second, or third tooth assembly along its width, the free ends of the aforementioned two first dielectric groups can be further connected to the second or third dielectric group, and more first, second, or third dielectric groups can be connected through the second or third dielectric group. Thus, the first, second, and third dielectric groups can ensure strong versatility while meeting basic phase-shifting functions. In the design of phase shifters with different port numbers in the same frequency band, it is only necessary to connect the single and multiple phase-shifting dielectric units according to the phase-shifting multiple relationship based on the different port numbers to achieve the overall phase shifting ratio required by the phase shifter and complete the phase shifter topology design. At the same time, the general structure of the above-mentioned media has fewer types of phase-shifting media, requires less mold investment, does not require frequent mold opening, and shortens the development cycle; moreover, the phase-shifting media is a standardized design, and shifters with different power divisions do not need to redesign the phase-shifting media, but only need to select from the standardized media, which can also shorten the development cycle.

Detailed Implementation

[0051] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0052] It should be noted that when an element is said to be "fixed" to another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly" on another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0053] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0056] The inventors of this application have discovered that the media in current green cavity phase shifters are mostly spliced. Phase shifters with different numbers of output ports require the design of independent media structures, resulting in a large number of molds and materials, high investment costs, and long development cycles. Alternatively, multiple sets of the same media are used. Although this solution reduces the types of media and the number of molds, its application scope is limited. Under the current short cable phase shifter and cableless phase shifter technologies, it only supports the use of a small number of port phase shifters. When facing phase shifters with more than six ports, because the short cable or cableless phase shifter is relatively long, and excessively long coaxial cables cannot be used to compensate for the phase, it is impossible to design the overall phase shift ratio required by the phase shifter by using only one multiple of the phase shifting media.

[0057] To resolve the above issues, please refer to the following: Figures 1 to 6 This embodiment provides a universal dielectric structure, specifically a universal dielectric structure for a base station antenna cavity phase shifter. The universal dielectric structure includes a first dielectric group 100, a second dielectric group 200, and a third dielectric group 300.

[0058] Please refer to the following: Figure 1 and Figure 2 The first medium group 100 is arranged in pairs, and the first medium group 100 includes a first medium 100a and a second medium 100b.

[0059] It should be noted that the first medium 100a and the second medium 100b are arranged in the form of sheets or plates, and the first medium 100a and the second medium 100b are narrow and long, having a length direction (shown in the X direction in the figure), a width direction (shown in the Y direction in the figure) and a thickness direction (shown in the Z direction in the figure).

[0060] Specifically, the first medium 100a and the second medium 100b are engaged along the thickness direction. One end of the first medium 100a along the length direction is provided with a hook 110, and one end of the second medium 100b along the length direction is provided with a slot 120. The hook 110 on the first medium 100a in one first medium group 100 is nested with the slot 120 on the second medium 100b in another first medium group 100. Furthermore, the other end of the first medium 100a and / or the second medium 100b along the length direction is provided with a first locking tooth assembly 130.

[0061] Optionally, the other end of the first medium 100a along the length direction and the other end of the second medium 100b along the length direction are respectively provided with the first tooth assembly 130. Alternatively, only the other end of the first medium 100a along the length direction is provided with the first tooth assembly 130. Or, only the other end of the second medium 100b along the length direction is provided with the first tooth assembly 130. This embodiment does not limit this.

[0062] Please refer to the following: Figure 3 and Figure 4 The second medium group 200 includes a third medium 200a and a fourth medium 200b.

[0063] Similar to the first medium 100a and the second medium 100b, the third medium 200a and the fourth medium 200b are arranged in a sheet or plate shape, and are narrow and elongated in shape, having a length direction, a width direction, and a thickness direction. During assembly, the length direction of the third medium 200a and the fourth medium 200b is parallel to the length direction of the first medium 100a and the second medium 100b; the width direction of the third medium 200a and the fourth medium 200b is parallel to the width direction of the first medium 100a and the second medium 100b; and the thickness direction of the third medium 200a and the fourth medium 200b is parallel to the thickness direction of the first medium 100a and the second medium 100b.

[0064] Specifically, the third medium 200a and the fourth medium 200b are engaged along the thickness direction. The third medium 200a and / or the fourth medium 200b are respectively provided with second tooth assemblies 210 at both ends along the length direction. The second tooth assemblies 210 are used to engage with the first tooth assembly 130 or the second tooth assembly 210 along the width direction.

[0065] Optionally, the second tooth assembly 210 is provided at both ends of the third medium 200a along the length direction and at both ends of the fourth medium 200b along the length direction. Alternatively, the second tooth assembly 210 is provided only at both ends of the third medium 200a along the length direction. Or, the second tooth assembly 210 is provided only at both ends of the fourth medium 200b along the length direction. This embodiment does not limit this.

[0066] It should be noted that the second tooth assembly 210 is used to engage with the first tooth assembly 130 or the second tooth assembly 210 in the width direction, meaning that the second tooth assembly 210 can engage with the first tooth assembly 130 in the width direction, and can also engage with the second tooth assembly 210 in another second medium group 200 in the width direction.

[0067] Please refer to the following: Figure 5 and Figure 6The third medium group 300 includes the fifth medium 300a and the sixth medium 300b.

[0068] Similar to the first medium 100a, second medium 100b, third medium 200a, and fourth medium 200b, the fifth medium 300a and sixth medium 300b are arranged in a sheet or plate shape, and are narrow and elongated in shape, having a length direction, a width direction, and a thickness direction. During assembly, the length direction of the fifth medium 300a and sixth medium 300b is parallel to the length direction of the first medium 100a and the second medium 100b; the width direction of the fifth medium 300a and sixth medium 300b is parallel to the width direction of the first medium 100a and the second medium 100b; and the thickness direction of the fifth medium 300a and sixth medium 300b is parallel to the thickness direction of the first medium 100a and the second medium 100b.

[0069] Specifically, the fifth medium 300a and the sixth medium 300b are engaged along the thickness direction. The fifth medium 300a and / or the sixth medium 300b are respectively provided with a third tooth assembly 310 at both ends along the length direction. The third tooth assembly 310 is used to engage with the first tooth assembly 130, the second tooth assembly 210 or the third tooth assembly 310 along the width direction.

[0070] Optionally, third tooth assemblies 310 are respectively provided at both ends of the fifth medium 300a along the length direction and at both ends of the sixth medium 300b along the length direction. Alternatively, only the third tooth assemblies 310 are provided at both ends of the fifth medium 300a along the length direction. Or, only the third tooth assemblies 310 are provided at both ends of the sixth medium 300b along the length direction. This embodiment does not limit this.

[0071] It should be noted that the third tooth assembly 310 is used to engage with the first tooth assembly 130, the second tooth assembly 210 or the third tooth assembly 310 in the width direction, which means that the second tooth assembly 210 can engage with the first tooth assembly 130 in the width direction, engage with the second tooth assembly 210 in the width direction, and engage with the second tooth assembly 210 in another third medium group 300 in the width direction.

[0072] Among them, the first dielectric group 100 and the second dielectric group 200 are both one-time phase-shifting dielectrics, and the third dielectric group 300 is a one-and-a-half-time phase-shifting dielectric.

[0073] In the above-mentioned general medium structure, the first medium groups 100 are arranged in pairs, and the hook 110 on the first medium 100a in one of the first medium groups 100 is nested and connected with the slot 120 on the second medium 100b in the other first medium group 100. The slot 120 on the second medium 100b in one of the first medium groups 100 is nested and connected with the hook 110 on the first medium 100a in the other first medium group 100, thereby connecting the two first medium groups 100 to each other.

[0074] Based on this, since the second tooth assembly 210 can engage with the first tooth assembly 130 or the second tooth assembly 210 along the width direction, and the third tooth assembly 310 can engage with the first tooth assembly 130, the second tooth assembly 210 or the third tooth assembly 310 along the width direction, the free ends of the aforementioned two first media groups 100 (i.e., the ends without the hooks 110 and slots 120) can be further connected to the second media group 200 or the third media group 300, and more first media groups 100, second media groups 200 or third media groups 300 can be connected through the second media group 200 or the third media group 300. Therefore, the first dielectric group 100, the second dielectric group 200, and the third dielectric group 300 can ensure strong versatility while meeting basic phase-shifting functions. In the design of phase shifters with different port numbers in the same frequency band, it is only necessary to connect the single and multiple phase-shifting dielectric units according to the phase shifting ratio relationship based on the different port numbers to achieve the overall required phase shift ratio of the phase shifter and complete the phase shifter topology design. For example, in the conventional MF band, this architecture can effectively cover topologies from six ports to ten ports.

[0075] At the same time, the general structure of the above-mentioned media has fewer types of phase-shifting media, requires less mold investment, does not require frequent mold opening, and shortens the development cycle; moreover, the phase-shifting media is a standardized design, and shifters with different power divisions do not need to redesign the phase-shifting media, but only need to select from the standardized media, which can also shorten the development cycle.

[0076] Please refer to it again. Figure 1 and Figure 2 In some embodiments, the first tooth assembly 130 includes a first tooth body 131 and a first tooth groove 132, which are arranged along the length direction of the first medium 100a.

[0077] Please refer to it again. Figure 3 and Figure 4 Similarly, the second tooth assembly 210 includes a second tooth body 211 and a second tooth groove 212, which are arranged along the length direction of the third medium 200a.

[0078] Please refer to it again. Figure 5 and Figure 6 The third tooth assembly 310 includes a third tooth body 311 and a third tooth groove 312, which are arranged along the length direction of the fifth medium 300a.

[0079] The widths of the first tooth body 131, the second tooth body 211, and the third tooth body 311 are equal, the widths of the first tooth groove 132, the second tooth groove 212, and the third tooth groove 312 are equal, and the width of the first tooth body 131 is adapted to the width of the first tooth groove 132.

[0080] Therefore, the second tooth 211 can be nested with the first tooth groove 132, so that the second tooth assembly 210 engages with the first tooth assembly 130 along the width direction; or it can be nested with the second tooth groove 212 in another second medium group 200, so that the second tooth assembly 210 engages with the second tooth assembly 210 in another second medium group 200 along the width direction. Alternatively, the first tooth 131 can be nested with the second tooth groove 212, so that the second tooth assembly 210 engages with the first tooth assembly 130 along the width direction.

[0081] The third tooth 311 can be nested with the first tooth groove 132, so that the third locking tooth assembly 310 engages with the first locking tooth assembly 130 along the width direction; it can also be nested with the second tooth groove 212, so that the third locking tooth assembly 310 engages with the second locking tooth assembly 210 along the width direction; or it can be nested with the third tooth groove 312 in another third medium group 300, so that the third locking tooth assembly 310 engages with the third locking tooth assembly 310 in another third medium group 300 along the width direction. Alternatively, the first tooth 131 can be nested with the third tooth groove 312, so that the third locking tooth assembly 310 engages with the first locking tooth assembly 130 along the width direction; the second tooth 211 can be nested with the third tooth groove 312, so that the third locking tooth assembly 310 engages with the second locking tooth assembly 210 along the width direction.

[0082] In use, the toothed components on each medium group can be interchanged and combined, allowing different numbers of medium groups to be connected in different orders, thus adapting to different phase shifters and exhibiting strong versatility.

[0083] Understandably, the first tooth body 131 and the first tooth groove 132 are disposed on the side of the first medium 100a or the second medium 100b along the width direction, the second tooth body 211 and the second tooth groove 212 are disposed on the side of the third medium 200a or the fourth medium 200b along the width direction, and the third tooth body 311 and the third tooth groove 312 are disposed on the side of the fifth medium 300a or the sixth medium 300b along the width direction.

[0084] Furthermore, the width of the first tooth 131 matching the width of the first tooth groove 132 means that the width of the first tooth 131 is slightly larger than the width of the first tooth groove 132. When the first tooth 131 is engaged with the first tooth groove 132, an interference fit is formed between the first tooth 131 and the inner wall of the first tooth groove 132, thereby ensuring a stable connection. The second tooth 211, the third tooth 311, the second tooth groove 212, and the third tooth groove 312 are similar and will not be described in detail here.

[0085] Furthermore, the first tooth assembly 130 includes at least two first teeth 131.

[0086] By nesting different first tooth bodies 131 with the second tooth groove 212, the relative positions of the first medium group 100 and the second medium group 200 can be adjusted. By nesting different first tooth bodies 131 with the third tooth groove 312, the relative positions of the first medium group 100 and the third medium group 300 can be adjusted.

[0087] Similarly, the second tooth assembly 210 includes at least two second teeth 211.

[0088] By nesting different second teeth 211 with the first tooth groove 132, the relative positions of the first medium group 100 and the second medium group 200 can be adjusted. By nesting different second teeth 211 with the second tooth groove 212 in another second medium group 200, the relative positions of two consecutively arranged second medium groups 200 can be adjusted. By nesting different second teeth 211 with the third tooth groove 312, the relative positions of the second medium group 200 and the third medium group 300 can be adjusted.

[0089] Similarly, the third tooth assembly 310 includes at least two third teeth 311.

[0090] By nesting different third teeth 311 with the first tooth groove 132, the relative positions of the first medium group 100 and the third medium group 300 can be adjusted. Similarly, by nesting different third teeth 311 with the second tooth groove 212, the relative positions of the second medium group 200 and the third medium group 300 can be adjusted. Furthermore, by nesting different third teeth 311 with the third tooth groove 312 in another third medium group 300, the relative positions of two consecutively arranged third medium groups 300 can be adjusted.

[0091] Therefore, by adjusting the relative positions of two interconnected media groups through different nesting positions of several toothed components, the adjustment becomes more flexible and the adaptability is better.

[0092] Please refer to it again. Figure 1 and Figure 2In some embodiments, the first medium 100a has a first protrusion 140 on at least one side along the width direction, and the second medium 100b has a first buckle 150 on the side along the thickness direction facing the first medium 100a, and the first buckle 150 engages with the first protrusion 140.

[0093] When the above-mentioned general dielectric structure is applied to a phase shifter, the first dielectric 100a and the second dielectric 100b are located on both sides of the PCB board in the phase shifter along the thickness direction. During assembly, the first snap-fit ​​150 passes through the clearance guide groove on the PCB board and engages with the first protrusion 140, so that the first dielectric 100a and the second dielectric 100b are engaged to form the first dielectric assembly 100.

[0094] In this embodiment, a groove is formed on the first tooth body 131. The groove separates the first tooth body 131 into a first tooth portion 131a and a second tooth portion 131b, and a first protrusion 140 is disposed at the bottom of the groove. At this time, the first tooth body 131, the first tooth groove 132, the first protrusion 140 and the first latch 150 are all disposed at the end of the first medium 100a or the second medium 100b, making the structure of the first medium 100a and the second medium 100b more compact.

[0095] Please refer to it again. Figure 3 and Figure 4 In some embodiments, the third medium 200a has a second protrusion 220 on at least one side along the width direction, and the fourth medium 200b has a second buckle 230 on the side along the thickness direction facing the third medium 200a, and the second buckle 230 engages with the second protrusion 220.

[0096] Similar to the first medium 100a and the second medium 100b, the second latch 230 passes through the clearance guide groove on the PCB board and engages with the second protrusion 220, so that the third medium 200a and the fourth medium 200b are engaged to form the second medium group 200. In addition, the second tooth 211 also has a groove to accommodate the second protrusion 220, which will not be described in detail here.

[0097] Please refer to it again. Figure 5 and Figure 6 In some embodiments, the fifth medium 300a has a third protrusion 320 on at least one side along the width direction, and the sixth medium 300b has a third buckle 330 on the side along the thickness direction facing the fifth medium 300a, and the third buckle 330 engages with the third protrusion 320.

[0098] Similar to the first medium 100a, second medium 100b, third medium 200a, and fourth medium 200b, the third latch 330 passes through the clearance guide groove on the PCB board and engages with the third protrusion 320, so that the fifth medium 300a and the sixth medium 300b are engaged to form the third medium group 300. In addition, the third tooth 311 also has a groove to accommodate the third protrusion 320, which will not be described in detail here.

[0099] In some embodiments, the length of the first medium group 100 is less than the length of the second medium group 200, and the length of the first medium group 100 is less than the length of the third medium group 300.

[0100] Specifically, the first dielectric group 100 and the second dielectric group 200 have the same phase-shifting characteristics, differing only in length and connection characteristics. The third dielectric group 300 differs from both the first dielectric group 100 and the second dielectric group 200 in length, width, and phase-shifting characteristics.

[0101] The first dielectric group 100 facilitates the design of a symmetrical structure for the phase shifter. Designers only need to perform topology design for half the number of phase shifter ports, thereby reducing the number of ports required for phase shifter development and lowering the R&D difficulty. Simultaneously, the shorter length of the first dielectric group 100, used for intermediate connection sections, saves space in the phase shifter's length. Conversely, the second dielectric group 200 and the third dielectric group 300 are used for non-intermediate connection sections to meet the topology design requirements of their respective phase shifters.

[0102] Please refer to it again. Figure 3 and Figure 4 In some embodiments, the third medium 200a and / or the fourth medium 200b are provided with a through-hole 240 extending along the thickness direction, the through-hole 240 being used to attach the pull rod adapter.

[0103] In use, the pull rod adapter is inserted into the adapter hole 240 from the outside of the phase shifter. By pulling the pull rod adapter, the position of the second dielectric group 200 can be adjusted along the length direction, thereby adjusting the position of the entire dielectric general structure relative to the PCB board.

[0104] In summary, the aforementioned universal dielectric structure features fewer types of phase-shifting dielectrics, requires less mold investment, eliminates the need for frequent mold opening, and shortens the development cycle. The phase-shifting dielectric is a standardized design; shifters with different power division ratios do not require redesigning the phase-shifting dielectric, but can simply select from the standardized dielectrics, further shortening the development cycle. Simultaneously, the phase-shifting dielectric is smaller in size, requiring smaller molds with lower tonnage requirements and higher dimensional accuracy, thus reducing manufacturing costs and improving product quality. Furthermore, the interlocking of several locking tooth components on the dielectric assembly allows for not only interchangeable combinations but also adjustments to the relative positions of two dielectric assemblies through different nesting positions of these components, making adjustments more flexible and adaptable to different phase shifters, achieving dielectric versatility.
