Description

Technical Field

[0001] This utility model relates to the field of communications, and more specifically to a dual-polarized radiating component and an antenna having the above-mentioned dual-polarized radiating component. Background Technology

[0002] The mainstream dual-polarized radiating element structures currently available fall into three categories: printed circuit board (PCB) vibrators, die-cast vibrators, and sheet metal vibrators. Among multi-band antennas, PCBs offer a significant advantage due to their higher decoupling requirements and higher manufacturing precision. Sheet metal processing, with its precision limitations and thickness requirements, makes achieving decoupling particularly difficult. Therefore, there are relatively few fully sheet metal vibrators on the market that effectively achieve decoupling.

[0003] In addition, the power feeding structure in the conventional sheet metal integrated oscillator design usually presents a cross structure to achieve power feeding. The planes where the two polarization power feeding structures are located intersect at 90°, which makes its unfolded diagram not compact enough and generates a lot of waste. At the same time, the fixing structure is relatively complex and inconvenient to install. Utility Model Content

[0004] To address the technical problems existing in the prior art, namely that the traditional sheet metal integrated vibrator typically uses a cross-shaped feeding structure, which is difficult to assemble and has poor performance, the inventors of this utility model innovatively conceived of adopting a microstrip form for the feeding structure. This allows for easy coplanar arrangement, simplifying the assembly process and improving performance. To achieve the above technical effects, the first aspect of this utility model proposes a dual-polarized radiation component, which includes:

[0005] First radiating element;

[0006] Second radiating element;

[0007] Third radiating element;

[0008] A fourth radiating element, wherein the first radiating element, the second radiating element, the third radiating element, and the fourth radiating element are arranged coplanarly, and the first radiating element and the third radiating element are arranged diagonally, and the second radiating element and the fourth radiating element are arranged diagonally; and

[0009] A power supply assembly includes a first inner conductor, a first outer conductor, a second inner conductor, and a second outer conductor. The first inner conductor and the first outer conductor are respectively configured to power a first radiating element and a third radiating element with the same polarization direction. The second inner conductor and the second outer conductor are respectively configured to power a second radiating element and a fourth radiating element with another polarization direction. The first outer conductor and the second outer conductor are coplanar.

[0010] In this way, in the design scheme of the dual-polarized radiation component according to the present invention, the first outer conductor and the second outer conductor are arranged in the same plane, which simplifies the assembly process and reduces costs. Moreover, the dual-polarized radiation component according to the present invention can be realized in the form of sheet metal parts, thereby improving performance.

[0011] Preferably, in one embodiment of the present invention, the first inner conductor and the second inner conductor are electrically coupled to the first radiating element and the second radiating element respectively in a staggered manner.

[0012] In one embodiment of the present invention, the dual-polarized radiating component further includes a feeding network that feeds the first inner conductor, the first outer conductor, the second inner conductor, and the second outer conductor respectively. In this manner, the feeding network can feed the first radiating element, the second radiating element, the third radiating element, and the fourth radiating element respectively via the first inner conductor, the first outer conductor, the second inner conductor, and the second outer conductor.

[0013] In one embodiment of the present invention, the first inner conductor and the second inner conductor are constructed as sheet metal parts. This allows for the implementation of the first inner conductor and the second inner conductor according to the present invention at a lower cost, and improves both the cost and performance of the dual-polarized radiating assembly including the first inner conductor and the second inner conductor.

[0014] In one embodiment of the present invention, the portion of the first inner conductor and the first outer conductor coupled together is closer to the second radiating element than to the first radiating element, and the portion of the second inner conductor and the second outer conductor coupled together is closer to the first radiating element than to the second radiating element. This arrangement enables electrical connection to the respective radiating elements by electrically connecting the first inner conductor and the second inner conductor to the first radiating element and the second radiating element respectively in a staggered manner.

[0015] In one embodiment of the present invention, the first inner conductor bends at the first bend toward the side away from the first outer conductor and then bends at the second bend toward the side of the first radiating element to form a first coupling surface. The second inner conductor bends at the third bend toward the side away from the second outer conductor and then bends at the fourth bend toward the side of the second radiating element to form a second coupling surface. The vertical distance between the first bend and the first radiating element is less than the vertical distance between the third bend and the second radiating element.

[0016] In one embodiment of the present invention, the distance between the second bend and the plane of the inner conductor in which the first inner conductor and the second inner conductor are located is greater than the distance between the fourth bend and the plane of the inner conductor in which the first inner conductor and the second inner conductor are located.

[0017] In one embodiment of the present invention, the dual-polarized radiation assembly further includes a first limiting bracket disposed between the first inner conductor and the first outer conductor to maintain the first inner conductor and the first outer conductor being substantially parallel.

[0018] In one embodiment of the present invention, the dual-polarized radiation assembly further includes a second limiting bracket disposed between the second inner conductor and the second outer conductor to maintain the second inner conductor and the second outer conductor being substantially parallel.

[0019] In one embodiment of the present invention, the first limiting bracket and the second limiting bracket are integrally formed.

[0020] In one embodiment of the present invention, the dual-polarized radiating component further includes a decoupling stub disposed inside the radiating element and extending toward the center of the radiating surface. This allows for the suppression of unwanted frequencies in a multi-frequency antenna. Optionally, in one embodiment of the present invention, the decoupling stub is L-shaped. Preferably, in one embodiment of the present invention, the decoupling stub includes a first decoupling stub, a second decoupling stub, and a third decoupling stub, wherein the lengths of the first, second, and third decoupling stubs increase sequentially. In this way, the dual-polarized radiating component mentioned in the present invention can suppress current in different frequency bands, and decoupling over a wider frequency band can be achieved through multiple decoupling stubs of different lengths.

[0021] In one embodiment of the present invention, the dual-polarized radiating assembly further includes a loading stub disposed at the outer edge of the radiating element and extending perpendicularly to the radiating surface. In this manner, the impedance matching of the dual-polarized radiating assembly according to the present invention can be effectively adjusted by means of the loading stub.

[0022] In one embodiment of the present invention, the dual-polarized radiation component further includes a support member configured to provide support for the dual-polarized radiation component.

[0023] Furthermore, a second aspect of this invention discloses an antenna comprising the dual-polarized radiating component described in the first aspect of this invention.

[0024] In summary, in the design scheme of the dual-polarized radiating component and the corresponding antenna according to this utility model, the first outer conductor and the second outer conductor are arranged in a coplanar manner, which simplifies the assembly process and reduces costs. Moreover, the dual-polarized radiating component according to this utility model can be realized in the form of sheet metal parts, thereby improving performance. Attached Figure Description

[0033] As mentioned above, the existing technology has the following technical problems: the power feeding structure of the traditional sheet metal integrated oscillator is generally a cross structure to achieve power feeding, which is difficult to assemble and has poor performance. The inventor of this utility model innovatively thought of adopting a microstrip form for the power feeding structure, which is easy to set in a coplanar manner, which can simplify the assembly process and improve performance. In summary, to achieve the aforementioned technical effects, a dual-polarization radiation component is proposed according to a first aspect of this utility model. The dual-polarization radiation component includes: a first radiation element; a second radiation element; a third radiation element; and a fourth radiation element, wherein the first, second, third, and fourth radiation elements are coplanar, and the first and third radiation elements are diagonally arranged, as are the second and fourth radiation elements; and a power supply component, comprising a first inner conductor, a first outer conductor, a second inner conductor, and a second outer conductor, wherein the first inner conductor and the first outer conductor are respectively configured to power the first and third radiation elements in the same polarization direction, and wherein the second inner conductor and the second outer conductor are respectively configured to power the second and fourth radiation elements in the opposite polarization direction, wherein the first and second outer conductors are coplanar. In this manner, the first outer conductor and the second outer conductor are arranged in a coplanar manner in the design scheme of the dual-polarized radiating component according to the present invention, thereby simplifying the assembly process and reducing costs. Furthermore, the dual-polarized radiating component according to the present invention can be implemented in the form of a sheet metal part, thus improving performance. Preferably, the first inner conductor and the second inner conductor are electrically coupled to the first radiating element and the second radiating element respectively in a staggered manner.

[0034] The following will refer to Figures 1 to 2. Figure 4 This describes the dual-polarized radiating component proposed according to the present invention. Among them, Figure 1A A perspective view of a dual-polarized radiation assembly 100 according to an embodiment of the present invention is shown. Figure 1B A perspective view of a dual-polarized radiating assembly 100 according to an embodiment of the present invention is shown. Figure 2 A perspective view of two outer conductors of a dual-polarized radiation assembly 100 according to an embodiment of the present invention is shown. Figure 3 A perspective view of a limiting bracket for a dual-polarized radiation assembly 200 according to another embodiment of the present invention is shown, while Figure 4 A perspective view of a dual-polarized radiation component 200 according to another embodiment of the present invention is shown.

[0035] Figure 1A , Figure 1B and Figure 2Perspective views of the dual-polarized radiating component according to this invention are shown from different angles, wherein... Figure 1A This is a three-dimensional view taken from the side and above. Figure 1B This is a 3D view taken from the lower side. (Combined with...) Figure 1A , Figure 1B and Figure 2 It can be seen that the feeding structure of the dual-polarized radiating component according to this utility model adopts a microstrip form, which is easy to arrange in a coplanar manner, simplifying the assembly process and improving performance. Specifically, the dual-polarized radiating component 100 according to this utility model includes the following parts: a first radiating element 111, a second radiating element 112, a third radiating element 113, a fourth radiating element 114, and a feeding component 120, wherein the first radiating element 111, the second radiating element 112, the third radiating element 113, and the fourth radiating element 114 are arranged in a coplanar manner, and the first radiating element 111 and the third radiating element 113 are arranged diagonally, and the second radiating element 112 and the fourth radiating element 114 are arranged diagonally; The power supply assembly 120 includes a first inner conductor 121, a first outer conductor 123, a second inner conductor 122, and a second outer conductor 124. The first inner conductor 121 and the first outer conductor 123 are respectively configured to power a first radiating element 111 and a third radiating element 113 with the same polarization direction. The second inner conductor 122 and the second outer conductor 124 are respectively configured to power a second radiating element 112 and a fourth radiating element 114 with the opposite polarization direction. The first outer conductor 123 and the second outer conductor 124 are coplanar. Figure 2 The first outer conductor 123 and the second outer conductor 124 are arranged in the same plane.

[0036] Preferably, the first inner conductor 121 and the second inner conductor 122 are electrically connected to the first radiating element 111 and the second radiating element 112 respectively in a staggered manner. Figure 1A , Figure 1B and Figure 2As can be seen, the second inner conductor 122, located on the left, actually powers the second radiating element 112, located on the right, while the first inner conductor 121, located on the right, powers the first radiating element 111, located on the left. In other words, in one embodiment of the present invention, the portion of the first inner conductor 121 coupled to the first outer conductor 123 is closer to the second radiating element 112 than to the first radiating element 121, and the portion of the second inner conductor 122 coupled to the second outer conductor 124 is closer to the first radiating element 111 than to the second radiating element 112. In other words, this arrangement allows for electrical connection of the respective radiating elements by interleaving the first inner conductor 121 and the second inner conductor 122 with couplings to the first radiating element 111 and the second radiating element 112, respectively.

[0037] To achieve this power supply structure, optionally or alternatively, the first inner conductor 121 and the second inner conductor 122 are staggered at the ends near the first radiating element 111 and the second radiating element 112. Specifically, in one embodiment of the present invention, the first inner conductor 121 bends at the first bend 1212 toward the side away from the first outer conductor 123 and then bends at the second bend 1213 toward the side of the first radiating element 111 to form a first coupling surface 1211. The second inner conductor 122 bends at the third bend 1222 toward the side away from the second outer conductor 124 and then bends at the fourth bend 1223 toward the side of the second radiating element 112 to form a second coupling surface 1221. Here, the first and second inner conductors of the power supply assembly are coupled to the corresponding radiating elements. As shown in the figure above, during coupling, the radiating elements do not need to be electroplated; only the portions of the first and second inner conductors coupled to the corresponding radiating elements need to be electroplated, which effectively reduces costs. Another part of the radiating element and the feeding part of this dual-polarized radiating assembly are integrally formed using sheet metal technology, which reduces connection points and effectively lowers costs. Furthermore, the vertical distance between the first bend 1212 and the first radiating element 111 is less than the vertical distance between the third bend 1222 and the second radiating element 112. Optionally, in one embodiment of the present invention, the distance between the second bend 1213 and the inner conductor plane where the first inner conductor 121 and the second inner conductor 122 are located is greater than the distance between the fourth bend 1223 and the inner conductor plane where the first inner conductor 121 and the second inner conductor 122 are located. Of course, those skilled in the art should understand that if such a setting is changed, the design concept of this utility model can also be achieved. That is to say, those skilled in the art can set it up as follows: in one embodiment of this utility model, the first inner conductor 121 bends at the first bend 1212 toward the side away from the first outer conductor 123 and then bends at the second bend 1213 toward the side of the first radiating element 111 to form a first coupling surface 1211. The second inner conductor 122 bends at the third bend 1222 toward the side away from the second outer conductor 124 and then bends at the fourth bend 1223 toward the side of the second radiating element 112 to form a second coupling surface 1221. The vertical distance between the first bend 1212 and the first radiating element 111 is greater than the vertical distance between the third bend 1222 and the second radiating element 112.Optionally or additionally, in one embodiment of the present invention, the distance from the second bend 1213 to the plane of the inner conductors where the first inner conductor 121 and the second inner conductor 122 are located is less than the distance from the fourth bend 1223 to the plane of the inner conductors where the first inner conductor 121 and the second inner conductor 122 are located. The bending of the inner conductors allows the feed structure to be coplanar, greatly simplifying antenna assembly. Simultaneously, separating the inner conductor of the feed portion from the radiating portion reduces electroplating. Furthermore, the use of an all-sheet metal design effectively reduces costs compared to PCB vibrators. The feed structure employs an air microstrip form, effectively reducing losses.

[0038] As above Figure 1A and Figure 1B As shown, when the two inner conductors of the feed structure cross, the minimum distance between them is preferably greater than 1.5 mm to ensure isolation and matching of the two polarizations. In addition, the conductor overlap portions 1211 and 1221 (the lower layer region integrally formed with the inner conductor in the figure) in the coupling area of ​​the radiating element are preferably larger than 3 mm * 3 mm in area to achieve good matching, while reducing the impact of manufacturing tolerances on return loss and other performance.

[0039] It should be understood by those skilled in the art that the first radiating element 111, the second radiating element 112, the third radiating element 113, and the fourth radiating element 114 shown in the figure are all square, but the shape of these radiating elements is not limited to square; they can be rhomboid or other shapes. In this way, in the design of the dual-polarized radiating assembly 100 according to the present invention, the portions of the first inner conductor 121 coupled to the first outer conductor 123 and the portions of the second inner conductor 122 coupled to the second outer conductor 124 are coplanarly arranged, thereby simplifying the assembly process, reducing costs, and enabling the dual-polarized radiating assembly 100 according to the present invention to be implemented in the form of sheet metal parts, thus improving performance.

[0040] To power the feeding assembly according to this invention, in one embodiment, the dual-polarized radiating assembly further includes a feeding network (not shown), which feeds the first inner conductor 121, the first outer conductor 123, the second inner conductor 122, and the second outer conductor 124 respectively. In this manner, the feeding network can feed the first radiating element 111, the second radiating element 112, the third radiating element 113, and the fourth radiating element 114 respectively via the first inner conductor 121, the first outer conductor 123, the second inner conductor 122, and the second outer conductor 124, wherein the first outer conductor 123 and the second outer conductor 124 are as follows: Figure 2 The diagram shows a coplanar arrangement. Optionally, in accordance with this utility model... Figure 1A , Figure 1B and Figure 2 In the illustrated embodiment, the first inner conductor 121 and the second inner conductor 122 are constructed as sheet metal parts. This allows for the implementation of the first inner conductor 121 and the second inner conductor 122 according to the present invention at a lower cost, and improves both the cost and performance of the dual-polarized radiating assembly including the first inner conductor 121 and the second inner conductor 122.

[0041] To fix the first inner conductor 121 and the second inner conductor 122, which are constructed as sheet metal parts, and to maintain an appropriate distance between them, and to fix an appropriate distance between the first inner conductor 121 and the first outer conductor 123, and between the second inner conductor 122 and the second outer conductor 124, a limiting bracket can be provided. Figure 3 The image shows such a limiting bracket 230. Among them, Figure 3 A perspective view of a limiting bracket for a dual-polarized radiation assembly 200 according to another embodiment of the present invention is shown, while Figure 4 A perspective view of a dual-polarized radiation assembly 200 including the aforementioned limiting bracket 230, according to another embodiment of the present invention, is shown. Figure 3 and Figure 4 As can be seen from this, in one embodiment of the present invention, the dual-polarized radiation component 200 further includes a first limiting bracket 230, which is disposed between the first inner conductor 121 and the first outer conductor 123 to maintain the first inner conductor 121 and the first outer conductor 123 being substantially parallel. For example Figure 3 The right half of each limiting bracket 230 can be used to limit the position between the first inner conductor 121 and the first outer conductor 123. Specifically, the right abutment surface 232 is used to fix the first inner conductor 121, and the right abutment surface 231 is used to abut and fix the first outer conductor 123, thereby limiting the distance between the first inner conductor 121 and the first outer conductor 123. Similarly, in one embodiment of the present invention, the dual-polarized radiation assembly 200 further includes a second limiting bracket 230, which is disposed between the second inner conductor 122 and the second outer conductor 124 to maintain the second inner conductor 122 and the second outer conductor 124 substantially parallel. Specifically... Figure 3 It can be seen that, Figure 3The left half of each limiting bracket 230 can be used to limit the position between the second inner conductor 122 and the second outer conductor 124; that is, the left abutment surface 232 is used to fix the second inner conductor 122, and the left abutment surface 231 is used to abut and fix the second outer conductor 124, thereby limiting the distance between the second inner conductor 122 and the second outer conductor 124. Similarly, it is possible to... Figure 3 As can be seen, in one embodiment of this utility model, the first limiting bracket 230 and the second limiting bracket 230 are integrally formed. In this utility model, the cross structure is achieved by bending the inner conductor, thereby making the two polarized feeding structures parallel and coplanar, thus simplifying the fixing structure and facilitating installation. For example... Figure 2 As shown, because the two polarized feeding structures, such as the first outer conductor 123 and the second outer conductor 124, are arranged parallel and coplanar, we can use a single fastener to fix them together, making installation simpler and tolerances easier to control. That is, from... Figure 2 As can be seen, due to the parallel and coplanar arrangement of the power supply structure, the sheet metal unfolding is very compact and will not generate too much waste.

[0042] Furthermore, in order to ensure the radiation performance of the dual-polarized radiation component 100 according to the present invention, preferably, in accordance with Figure 1 of the present invention, Figure 2 as well as Figure 4 In the illustrated embodiment, the dual-polarized radiation assembly 100 further includes decoupling stubs 1111, 1121, 1131, and 1141, which are disposed inside the radiation elements 111, 112, 113, and 114 and extend toward the center of the radiation surface. Figure 1A , Figure 1B and Figure 2 In the illustrated embodiment, each radiating element includes mutually perpendicular decoupling stubs 1111, 1121, 1131, and 1141 positioned at the four interior corners. Of course, more or fewer decoupling stubs can be used to suppress unwanted frequencies in a multi-frequency antenna. For example, as... Figure 4 As shown, a single radiating element (e.g.) Figure 4 The uppermost radiating element shown includes, for example, at least three L-shaped decoupling stubs. Preferably, in accordance with the present invention... Figure 4In the illustrated embodiment, the decoupling stub includes a first decoupling stub 201, a second decoupling stub 202, and a third decoupling stub 203, wherein the lengths of the first decoupling stub 201, the second decoupling stub 202, and the third decoupling stub 203 increase sequentially. For example, the first decoupling stub may decouple for a first frequency band, the second decoupling stub may decouple for a second frequency band, and the third decoupling stub may decouple for a third frequency band. Therefore, the radiating element including these three decoupling stubs can achieve decoupling for the first, second, and third frequency bands. In this way, the dual-polarized radiating component mentioned in this invention can suppress current in different frequency bands, and decoupling over a wider frequency band can be achieved through multiple decoupling stubs of different lengths. In other words, this invention achieves decoupling design of the oscillator by improving the decoupling structure while using sheet metal. Furthermore, as described above... Figure 1A , Figure 1B and Figure 2 As shown, the dual-polarized radiating component mentioned in this utility model adds a decoupling stub compared to conventional dual-polarized radiating components. This decoupling stub forms a groove structure parallel to the vibrator arm. This groove structure can generate a choking effect at a specific frequency band, thereby suppressing the current in that frequency band and achieving the desired decoupling effect. In this application, the dual-polarized radiating component operates in the low-frequency band, while the choking frequency band is set in the high-frequency band. From a circuit perspective, achieving low-frequency pass-through and high-frequency block-through requires an inductor structure. Inductance requires the wire to be as thin as possible, but in sheet metal processing, the thickness and width of the wire are significantly limited, making it difficult to achieve an ideal decoupling effect. However, this dual-polarized radiating component can achieve the decoupling effect within the requirements of sheet metal processing by setting a decoupling stub, thus effectively reducing costs compared to printed circuit board (PCB) processing.

[0043] Furthermore, to adjust impedance matching, in one embodiment according to the present invention, the dual-polarized radiating assembly 100 further includes loading stubs 1112, 1122, 1132, and 1142, which are disposed at the outer edges of the radiating elements 111, 112, 113, and 114 and extend perpendicularly to the radiating surface. In this way, the impedance matching of the dual-polarized radiating assembly 100 according to the present invention can be effectively adjusted by means of the loading stubs 1112, 1122, 1132, and 1142. (See Figure 1...) Figure 2 and Figure 4In the illustrated embodiment, the loading stubs 1112, 1122, 1132, and 1142 extend perpendicularly to the radiating surface toward the feed network (not shown). This arrangement allows the loading stubs 1112, 1122, 1132, and 1142 to be installed without increasing the height of the dual-polarized radiating component according to the present invention, thereby avoiding new height requirements for the radome and not affecting the miniaturization requirements of the antenna including the dual-polarized radiating component 100 according to the present invention.

[0044] In one embodiment of the present invention, the dual-polarized radiation assembly further includes a support (not shown in the figure) configured to provide support for the dual-polarized radiation assembly 100 or 200.

[0045] Furthermore, a second aspect of this invention discloses an antenna comprising a patch module for an antenna as described in the first aspect of this invention.

[0046] In summary, in the design scheme of the dual-polarized radiating component and the corresponding antenna according to this utility model, the portion of the first inner conductor coupled to the first outer conductor and the portion of the second inner conductor coupled to the second outer conductor are arranged in a coplanar manner, which simplifies the assembly process and reduces costs. Moreover, the dual-polarized radiating component according to this utility model can be realized in the form of sheet metal parts, thereby improving performance.
