Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of communications, and more particularly to a dual-polarized radiation component and an antenna having the above dual-polarized radiation component. Background Art
[0002] The existing mainstream structural forms of dual-polarized radiation units are divided into the following three categories: printed circuit board (PCB) oscillators, die-cast oscillators, and sheet metal oscillators. Among current multi-band antennas, due to the relatively high requirement for decoupling, the PCB processing accuracy is relatively higher, so it has greater advantages. The sheet metal process makes it particularly difficult to achieve the decoupling effect due to its accuracy limitations and requirements for sheet metal thickness. Therefore, there are few sheet metal oscillators in the market that can effectively achieve decoupling.
[0003] In addition, the feeding structure in the design of a conventional sheet metal integrated oscillator generally presents a cross-shaped structure to achieve feeding. The planes where its two polarization feeding structures are located intersect at 90°, making its developed drawing not compact enough to generate a large amount of waste, and at the same time, the fixing structure is relatively complex and not convenient for installation. Summary of the Invention
[0004] In order to solve the technical problems existing in the prior art, that is, the feeding structure adopted by the traditional sheet metal integrated oscillator generally presents a cross-shaped structure to achieve feeding, which is difficult to assemble and has poor performance.

[0010] In this way, among the design schemes of the dual-polarization radiation component according to the present disclosure, the first outer conductor and the second outer conductor adopted are arranged coplanarly, so that the assembly process can be simplified and the cost can be reduced, and the dual-polarization radiation component according to the present disclosure can be realized in the form of a sheet metal part, improving the performance.
[0011] Preferably, in an embodiment according to the present disclosure, the first inner conductor and the second inner conductor are respectively electrically connected to the first radiation element and the second radiation element in a cross-misaligned and coupled manner.

[0014] In an embodiment according to the present disclosure, the part where the first inner conductor is coupled to the first outer conductor is closer to the second radiation element than to the first radiation element, and the part where the second inner conductor is coupled to the second outer conductor is closer to the first radiation element than to the second radiation element. Such an arrangement can realize the electrical connection to the corresponding radiation elements by electrically connecting the first inner conductor and the second inner conductor to the first radiation element and the second radiation element in a cross-misaligned and coupled manner.
[0015] In one embodiment according to the present disclosure, the first inner conductor bends toward the side away from the first outer conductor at the first bending portion, then bends toward the side of the first radiating element at the second bending portion and forms a first coupling surface. The second inner conductor bends toward the side away from the second outer conductor at the third bending portion, then bends toward the side of the second radiating element at the fourth bending portion and forms a second coupling surface.

[0033] As described above, the following technical problems exist in the prior art, that is, the feeding structure adopted by the traditional sheet metal integrated oscillator generally presents a cross structure to achieve feeding, which is difficult to assemble and has poor performance. The inventors of the present disclosure innovatively thought of adopting a microstrip form for the feeding structure, which is easy to be coplanarly arranged, can not only simplify the assembly process but also improve the performance. Generally speaking, in order to achieve the above technical effects, according to the first aspect of the present disclosure, a dual-polarization radiation component is proposed, and the dual-polarization radiation component includes: a first radiation element; a second radiation element; a third radiation element; a fourth radiation element, wherein the first radiation element, the second radiation element, the third radiation element, and the fourth radiation element are coplanarly arranged and the first radiation element and the third radiation element are diagonally arranged, and the second radiation element and the fourth radiation element are diagonally arranged; and a feeding component, the feeding component includes 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 feed the first radiation element and the third radiation element in the same polarization direction, and wherein the second inner conductor and the second outer conductor are respectively configured to feed the second radiation element and the fourth radiation element in another polarization direction, wherein the first outer conductor and the second outer conductor are coplanarly arranged. In this way, in the design scheme of the dual-polarization radiation component according to the present disclosure, the adopted first outer conductor and the second outer conductor are coplanarly arranged, so that the assembly process can be simplified and the cost can be reduced, and the dual-polarization radiation component according to the present disclosure can be realized in the form of a sheet metal part to improve the performance. Preferably, the first inner conductor and the second inner conductor are cross-misaligned and are respectively coupled and electrically connected to the first radiation element and the second radiation element.
[0034] The following will describe the dual-polarization radiation component proposed according to the present disclosure with reference to FIGS. 1 to Figure 4 to. Figure 1A FIG. shows a perspective three-dimensional view of a dual-polarization radiation component 100 according to an embodiment of the present disclosure, Figure 1B FIG. shows a perspective three-dimensional view of the dual-polarization radiation component 100 from another perspective according to an embodiment of the present disclosure, Figure 2 FIG. shows a perspective schematic view of two outer conductors of the dual-polarization radiation component 100 according to an embodiment of the present disclosure, Figure 3 FIG. shows a perspective three-dimensional view of a limiting bracket of a dual-polarization radiation component 200 according to another embodiment of the present disclosure, while Figure 4 FIG. shows a perspective three-dimensional view of the dual-polarization radiation component 200 according to another embodiment of the present disclosure.
[0035] Figure 1A 、 Figure 1B and Figure 2Perspective views of a dual-polarization radiation assembly in accordance with the present disclosure are shown from different perspectives, where Figure 1A is a perspective view looking from the upper side, and Figure 1B is a perspective view looking from the lower side. Combining Figure 1A , Figure 1B and Figure 2 it can be seen that the feeding structure of the dual-polarization radiation assembly in accordance with the present disclosure takes a microstrip form, which is easy to be arranged coplanarly, can simplify the assembly process and improve the performance. Specifically, the dual-polarization radiation assembly 100 in accordance with the present disclosure includes the following parts, namely: a first radiation element 111, a second radiation element 112, a third radiation element 113, a fourth radiation element 114 and a feeding assembly 120, where the first radiation element 111, the second radiation element 112, the third radiation element 113 and the fourth radiation element 114 are arranged coplanarly and the first radiation element 111 and the third radiation element 113 are arranged diagonally, and the second radiation element 112 and the fourth radiation element 114 are arranged diagonally; the feeding assembly 120 includes a first inner conductor 121, a first outer conductor 123, a second inner conductor 122 and a second outer conductor 124, where the first inner conductor 121 and the first outer conductor 123 are respectively configured to feed the first radiation element 111 and the third radiation element 113 in the same polarization direction, and where the second inner conductor 122 and the second outer conductor 124 are respectively configured to feed the second radiation element 112 and the fourth radiation element 114 in another polarization direction, where the first outer conductor 123 and the second outer conductor 124 are arranged coplanarly, that is Figure 2 the first outer conductor 123 and the second outer conductor 124 are arranged coplanarly in
[0036] Preferably, the first inner conductor 121 and the second inner conductor 122 are electrically connected to the first radiation element 111 and the second radiation element 112 respectively in a cross-misaligned manner and coupled. From Figure 1A , Figure 1B and Figure 2It can be seen that the second inner conductor 122 located relatively on the left actually feeds the second radiation element 112 located relatively on the right, while the first inner conductor 121 located relatively on the right actually feeds the first radiation element 111 located relatively on the left. In other words, in an embodiment according to the present disclosure, the portion where the first inner conductor 121 is coupled to the first outer conductor 123 is closer to the second radiation element 112 than to the first radiation element 121, and the portion where the second inner conductor 122 is coupled to the second outer conductor 124 is closer to the first radiation element 111 than to the second radiation element 112. In other words, such an arrangement can achieve the electrical connection to the corresponding radiation element by electrically connecting the first inner conductor 121 and the second inner conductor 122 to the first radiation element 111 and the second radiation element 112 respectively in a cross - staggered manner.
[0037] To implement such a feeding structure, optionally or alternatively, the first inner conductor 121 and the second inner conductor 122 are to be staggered at one end close to the first radiating element 111 and the second radiating element 112. Specifically, in an embodiment according to the present disclosure, the first inner conductor 121 is bent away from the first outer conductor 123 at the first bending portion 1212 and then bent towards the first radiating element 111 at the second bending portion 1213 to form a first coupling surface 1211, and the second inner conductor 122 is bent away from the second outer conductor 124 at the third bending portion 1222 and then bent towards the second radiating element 112 at the fourth bending portion 1223 to form a second coupling surface 1221. Here, the first inner conductor and the second inner conductor of the feeding assembly are coupled to the corresponding radiating elements. During the coupling connection, the radiating elements do not need to be electroplated, but only the portions of the first inner conductor and the second inner conductor that are coupled to the corresponding radiating elements need to be electroplated, which can effectively reduce the cost. Another part of the radiating elements of the dual-polarization radiating assembly and the feeding part are integrally formed by sheet metal processing, which can reduce the connection points and effectively reduce the cost. In addition, the vertical distance from the first bending portion 1212 to the first radiating element 111 is less than the vertical distance from the third bending portion 1222 to the second radiating element 112. Optionally, in an embodiment according to the present disclosure, the distance from the second bending portion 1213 to the inner conductor plane where the first inner conductor 121 and the second inner conductor 122 are located is greater than the distance from the fourth bending portion 1223 to 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 settings are swapped, the design concept according to the present disclosure can also be realized, that is: those skilled in the art can set it as follows. In an embodiment according to the present disclosure, the first inner conductor 121 is bent away from the first outer conductor 123 at the first bending portion 1212 and then bent towards the first radiating element 111 at the second bending portion 1213 to form a first coupling surface 1211, and the second inner conductor 122 is bent away from the second outer conductor 124 at the third bending portion 1222 and then bent towards the second radiating element 112 at the fourth bending portion 1223 to form a second coupling surface 1221, wherein the vertical distance from the first bending portion 1212 to the first radiating element 111 is greater than the vertical distance from the third bending portion 1222 to the second radiating element 112.Optionally or additionally, in one embodiment according to the present disclosure, the distance between the second bending portion 1213 and the inner conductor plane where the first inner conductor 121 and the second inner conductor 122 are located is less than the distance between the fourth bending portion 1223 and the inner conductor plane where the first inner conductor 121 and the second inner conductor 122 are located. By bending the inner conductors, the feeding structure is arranged coplanarly, greatly simplifying the assembly of the antenna. At the same time, by separating the inner conductors of the feeding part from the radiation part, electroplating can be reduced. And because a full sheet metal solution is used, the cost is effectively reduced compared to a PCB oscillator. The feeding structure adopts an air microstrip form, effectively reducing the loss.
[0038] As above Figure 1A and Figure 1B As shown, when the two inner conductors of the feeding structure cross, the minimum distance between them can preferably be greater than 1.5 mm to ensure the isolation and matching of the two polarizations. In addition, the overlapping portions 1211 and 1221 of the inner conductors in the coupling region of the radiation element (the lower layer region integrally formed with the inner conductor shown in the figure) can preferably be greater than 3 mm * 3 mm in area to achieve good matching and at the same time reduce the influence of manufacturing tolerances on return loss and other performances.
[0039] Here, those skilled in the art should understand that the illustrated first radiation element 111, second radiation element 112, third radiation element 113, and fourth radiation element 114 are all square, but the shapes of these radiation elements are not limited to square, and they can be rhombic or other shapes. In this way, in the design scheme of the dual-polarization radiation assembly 100 according to the present disclosure, 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 arranged coplanarly, so that the assembly process can be simplified and the cost can be reduced, and the dual-polarization radiation assembly 100 according to the present disclosure can be realized in the form of a sheet metal part, improving the performance.
[0040] In order to feed the feeding assembly introduced according to the present disclosure, in one embodiment according to the present disclosure, the dual-polarization radiation assembly further includes a feeding network (not shown in the figure), and the feeding network 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 way, the feeding network can feed the first radiation element 111, the second radiation element 112, the third radiation element 113, and the fourth radiation element 114 via the first inner conductor 121, the first outer conductor 123, the second inner conductor 122, and the second outer conductor 124 respectively, where the first outer conductor 123 and the second outer conductor 124 are asFigure 2 are arranged coplanarly. Optionally, among the embodiments shown in Figure 1A , Figure 1B and Figure 2 , the first inner conductor 121 and the second inner conductor 122 are configured as sheet metal parts. In this way, the first inner conductor 121 and the second inner conductor 122 according to the present disclosure can be realized at a lower cost, and the cost and performance of the dual-polarization radiation component including the first inner conductor 121 and the second inner conductor 122 are both improved.
[0041] In order to fix the first inner conductor 121 and the second inner conductor 122 configured as sheet metal parts, and keep an appropriate distance between them, and 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. Such a limiting bracket 230 is shown in Figure 3 . Among them, Figure 3 shows a perspective view of the limiting bracket of the dual-polarization radiation component 200 according to another embodiment of the present disclosure, while Figure 4 shows a perspective view of the dual-polarization radiation component 200 including the above-mentioned limiting bracket 230 according to another embodiment of the present disclosure. It can be seen from Figure 3 and Figure 4 that in an embodiment according to the present disclosure, the dual-polarization radiation component 200 further includes a first limiting bracket 230, and the first limiting bracket 230 is arranged between the first inner conductor 121 and the first outer conductor 123 to keep the first inner conductor 121 and the first outer conductor 123 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, that is, the right abutting surface 232 is used to fix the first inner conductor 121, and the right abutting surface 231 is used to abut and fix the first outer conductor 123, so as to be able to limit the distance between the first inner conductor 121 and the first outer conductor 123. Similarly, in an embodiment according to the present disclosure, the dual-polarization radiation component 200 further includes a second limiting bracket 230, and the second limiting bracket 230 is arranged between the second inner conductor 122 and the second outer conductor 124 to keep the second inner conductor 122 and the second outer conductor 124 substantially parallel. Specifically, it can be seen from Figure 3 that Figure 3Half of the left side 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 abutting surface 232 on the left side is used to fix the second inner conductor 122, and the left abutting surface 231 is used to abut and fix the second outer conductor 124, so as to be able to limit the distance between the second inner conductor 122 and the second outer conductor 124. Similarly, it can be seen from Figure 3 that in an embodiment according to the present disclosure, the first limiting bracket 230 and the second limiting bracket 230 are integrally formed. In the present disclosure, the cross structure is realized by bending the inner conductor, so that the two polarized feeding structures are arranged in parallel and coplanar, thus simplifying the fixing structure and facilitating installation. As Figure 2 shown, since the two polarized feeding structures, such as the first outer conductor 123 and the second outer conductor 124, are arranged in parallel and coplanar, we can share a fixing part to fix them, and the installation is simpler and it is easier to control the tolerance. That is, it can be seen from Figure 2 that due to the parallel and coplanar arrangement of the feeding structures, the sheet metal development drawing is very compact and does not generate too much waste.
[0042] In addition, in order to ensure the radiation performance of the dual-polarized radiation component 100 according to the present disclosure, preferably, in the embodiments shown in FIG. 1, Figure 2 and Figure 4 of the present disclosure, the dual-polarized radiation component 100 further includes decoupling stubs 1111, 1121, 1131 and 1141, and the decoupling stubs 1111, 1121, 1131 and 1141 are arranged inside the radiation elements 111, 112, 113 and 114 and extend towards the center of the radiation surface. In Figure 1A , Figure 1B and Figure 2 of the embodiments shown, each radiation element includes mutually perpendicular decoupling stubs 1111, 1121, 1131 and 1141 arranged at the four inner corners. Of course, more or fewer decoupling stubs can also be arranged, and in this way, the suppression of other non-desired frequencies can be realized in a multi-band antenna. For example, as Figure 4 shown, a single radiation element (such as Figure 4 the uppermost radiation element shown) includes, for example, at least three L-shaped decoupling stubs. Preferably, in Figure 4Among the illustrated embodiments, 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 in sequence. For example, if the first decoupling stub achieves a decoupling effect for a first frequency band, the second decoupling stub achieves a decoupling effect for a second frequency band, and the third decoupling stub achieves a decoupling effect for a third frequency band, then the radiating element including the above three decoupling stubs can achieve decoupling for the above-mentioned first frequency band, second frequency band, and third frequency band. In this way, the dual-polarization radiating assembly mentioned in the present disclosure can produce an inhibitory effect on currents of different frequency bands, and decoupling for a wider frequency band can be achieved through multiple decoupling stubs with different lengths. That is to say, the present disclosure realizes the decoupling design of the oscillator by improving the decoupling structure in the case of using sheet metal. In addition, as described above Figure 1A , Figure 1B and Figure 2 shown, the dual-polarization radiating assembly mentioned in the present disclosure has an increased decoupling stub compared with a conventional dual-polarization radiating assembly. The decoupling stub is parallel to the oscillator arm to form a groove structure, and this groove structure can produce a choking effect at a specific frequency band, thereby realizing the suppression of the current in this frequency band and achieving the desired decoupling effect. In this application, the dual-polarization radiating assembly operates in a low-frequency band, and the choking frequency band is set in a high-frequency band. From the perspective of the circuit, an inductor structure is required to achieve passing low frequencies and blocking high frequencies. The generation of an inductor requires the wire to be as thin as possible, and there are relatively large limitations on the thickness and width of the wire in the sheet metal process. Therefore, it is difficult to achieve an ideal decoupling effect. However, the dual-polarization radiating assembly can achieve the decoupling effect by setting the decoupling stub within the requirements of the sheet metal process, and thus is formed by the sheet metal process, effectively reducing the cost compared with the printed circuit board (PCB) process.
[0043] In addition, in order to adjust the impedance matching, in an embodiment according to the present disclosure, the dual-polarization radiating assembly 100 further includes loading stubs 1112, 1122, 1132, and 1142. The loading stubs 1112, 1122, 1132, and 1142 are arranged at the outer edges of the radiating elements 111, 112, 113, and 114 and extend perpendicular to the radiation surface. In this way, the impedance matching of the dual-polarization radiating assembly 100 according to the present disclosure can be effectively adjusted by means of the loading stubs 1112, 1122, 1132, and 1142. In FIGS. 1, Figure 2 and Figure 4Among the illustrated embodiments, the loading stubs 1112, 1122, 1132, and 1142 extend in a direction perpendicular to the radiation surface toward a feed network (not shown in the figure). Such an arrangement enables the above loading stubs 1112, 1122, 1132, and 1142 to be provided without increasing the height of the dual-polarization radiation assembly according to the present disclosure, thereby not imposing new height requirements on the radome and not affecting the miniaturization requirements of the antenna including the dual-polarization radiation assembly 100 according to the present disclosure.
[0044] In one embodiment according to the present disclosure, the dual-polarization radiation assembly further includes a support member (not shown in the figure), and the support member is configured to provide support for the dual-polarization radiation assembly 100 or 200.
[0045] In addition, a second aspect of the present disclosure also discloses an antenna, and the antenna includes the patch module for an antenna according to the first aspect of the present disclosure.
[0046] In summary, in the design of the dual-polarization radiation assembly and the corresponding antenna according to the present disclosure, the portions where the first inner conductor is coupled to the first outer conductor and the portions where the second inner conductor is coupled to the second outer conductor are arranged coplanarly, so that the assembly process can be simplified and the cost can be reduced, and moreover, the dual-polarization radiation assembly according to the present disclosure can be implemented in the form of a sheet metal part to improve performance.
[0047] The foregoing are only alternative embodiments of the embodiments of the present disclosure and are not intended to limit the embodiments of the present disclosure.
