Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to radiator assemblies and dual-polarized omnidirectional antennas, and methods for their fabrication. Background Technology

[0002] With the development of mobile communication technology, data services place higher demands on system bandwidth and multi-network coordination. To save resources and achieve wide coverage, omnidirectional antennas need to have wide bandwidth and dual polarization characteristics to be compatible with existing network standards and support multiple-input multiple-output (MIMO) technology, while maintaining omnidirectional radiation characteristics in the horizontal direction. Therefore, the use of wide-band dual-polarized omnidirectional antennas is becoming increasingly widespread.

[0003] In the existing technology, dual-polarized omnidirectional antennas generally adopt a structure that combines vertically polarized antennas and horizontally polarized antennas. Vertically polarized antennas mostly adopt a single-cone or double-cone structure, while horizontally polarized antennas require additional independent radiating elements and are larger in size, resulting in a complex structure and high cost for dual-polarized omnidirectional antennas.

[0004] Some dual-polarized omnidirectional antennas in related technologies design the vertically polarized upper conical structure as a cylinder and an upper conical part connected to the cylinder. Multiple slotted elements are arranged circumferentially on the cylindrical part to replace the traditional horizontally polarized antenna. This achieves horizontal polarization by reusing the vertically polarized upper conical structure, thus simplifying the antenna structure and reducing costs. However, the fabrication process for the upper conical structure of this dual-polarized omnidirectional antenna is complex and difficult. Summary of the Invention

[0005] Therefore, it is necessary to address the issues of complex manufacturing processes and high manufacturing difficulty of the upper conical structure of dual-polarized omnidirectional antennas in related technologies by providing a radiator assembly, a dual-polarized omnidirectional antenna, and their manufacturing methods.

[0062] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0063] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0064] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0065] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0066] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0067] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0068] As mentioned in the background section, some dual-polarized omnidirectional antennas in the related technology design a vertically polarized upper conical structure as a cylinder and an upper conical portion connected to the cylinder, with multiple slotted elements arranged circumferentially on the cylindrical portion. However, the manufacturing process of the upper conical structure of such a dual-polarized omnidirectional antenna is complex and difficult. Specifically, the manufacturing process of the upper conical structure of such a dual-polarized omnidirectional antenna requires first using processes such as drawing and spinning to form the cylinder and the upper conical portion connected to the cylinder, and then machining the slotted elements on the side wall of the cylinder. The side wall of the already formed upper conical structure has a circumferentially closed curved surface structure. Machining the slotted elements on the already formed upper conical structure cylinder can be achieved using processes such as laser processing, stamping, or milling. Therefore, it is evident that the manufacturing process of the upper conical structure of a dual-polarized omnidirectional antenna is complex and difficult.

[0069] Please refer to Figure 1 Combination Figure 2 and Figure 3 One embodiment of this application provides a radiator assembly 10, which includes a plurality of radiators 100, each radiator 100 including a connecting plate 110 and two bending plates 121.

[0070] The two ends of the connecting plate 110 along the first direction are the first end 110a and the second end 110b, respectively. From the first end 110a to the second end 110b, the width of the connecting plate 110 gradually narrows from both sides to the middle, wherein the width direction of the connecting plate 110 is the second direction.

[0071] Both bending plates 121 are located on the side of the first end 110a away from the second end 110b, and one end of each bending plate 121 is connected to both ends of the connecting plate 110 along the second direction. The two bending plates 121 are arranged opposite each other and are located on both sides of the plane of the connecting plate 110 along the third direction. Each bending plate 121 is provided with at least one slot vibrator 1211. The third direction, the second direction, and the first direction intersect each other.

[0072] In this assembly, the connecting plates 110 of the multiple radiators 100 are assembled in a cross-sectional manner with their respective width directions as the intersection area, so that the bending plates 121 of the multiple radiators 100 are arranged sequentially around the circumference of the radiator assembly 10.

[0073] Specifically, in Figures 1 to 3 In the illustrated embodiment, the radiator assembly 10 includes two radiators 100, namely a first radiator 100a and a second radiator 100b. The connecting plate 110 of the first radiator 100a is a first connecting plate 111, and the connecting plate 110 of the second radiator 100b is a second connecting plate 112. The first connecting plate 111 and the second connecting plate 112 are cross-assembled with their respective width directions intersecting at their midpoints, thereby allowing the two bent plates 121 connected to the first connecting plate 111 and the two bent plates 121 connected to the second connecting plate 112 to be arranged sequentially around the circumference of the radiator assembly 10.

[0074] Optionally, the third direction, the second direction, and the first direction are perpendicular to each other.

[0075] It is understandable that each radiator 100 has a corresponding first direction, second direction, and third direction. The second direction of each radiator 100 corresponds to the width direction of the connecting plate 110, and the third direction corresponds to the thickness direction of the connecting plate 110. Therefore, when the connecting plates 110 of multiple radiators 100 are cross-assembled, the first direction, second direction, and third direction corresponding to the multiple radiators 100 are different from each other.

[0076] Since one end of each of the two bent plates 121 is connected to both ends of the connecting plate 110 along the second direction, and the two bent plates 121 are arranged opposite each other and located on both sides of the plane of the connecting plate 110 along the third direction, it can be understood that the two bent plates 121 have an included angle with the plane of the connecting plate 110.

[0077] In the aforementioned radiator assembly 10, the bent plates 121 of the multiple radiators 100 are arranged sequentially around the circumference of the radiator assembly 10, such that the slotted vibrators 1211 on each bent plate 121 are arranged sequentially around the circumference of the radiator assembly 10, thereby achieving omnidirectional radiation along the circumference of the radiator assembly 10, which is equivalent to the function of a cylinder with multiple slotted vibrators in the upper conical structure of a traditional dual-polarized omnidirectional antenna. Since the connecting plate 110 gradually narrows from the first end 110a to the second end 110b, and the connecting plates 110 of the multiple radiators 100 are assembled to each other with their respective width directions intersecting at the middle, the intersecting multiple connecting plates 110, through the gradual width design, can ensure the stability of the broadband impedance of vertical polarization, which is equivalent to the function of the upper conical part in the upper conical structure of a traditional dual-polarized omnidirectional antenna. Since the bent plate 121 of the radiator 100 is not a circumferentially closed curved surface structure, the processing difficulty of fabricating the slotted vibrator 1211 on it is low. For example, the bent plate 121 with the slotted vibrator 1211 can be stamped out using an integral stamping process. When manufacturing the radiator assembly 10, multiple radiators 100 can be fabricated first, and then the connecting plates 110 of the multiple radiators can be cross-assembled, without the need for traditional negative pressure processes such as drawing and spinning. In summary, the above-mentioned radiator assembly 10 can replace the function of the upper cone structure of the traditional dual-polarized omnidirectional antenna, and the processing technology is simple and the processing difficulty is low.

[0078] Please combine Figures 1 to 3 In some embodiments, the number of radiators 100 is at least two, one of which is a first radiator 100a and the other is a second radiator 100b. The connecting plate 110 of the first radiator 100a is a first connecting plate 111, and the connecting plate 110 of the second radiator 100b is a second connecting plate 112.

[0079] The first end 110a of the first connecting plate 111 is provided with a first clearance gap 101, and the second end 110b of the second connecting plate 112 is provided with a second clearance gap 102. The first end 110a of the second connecting plate 112 is engaged with the first clearance gap 101, and the second end 110b of the first connecting plate 111 is engaged with the second clearance gap 102.

[0080] Understandably, the first clearance gap 101 is located at the middle of the first end 110a of the first connecting plate 111 along the corresponding second direction. The second clearance gap 102 is located at the middle of the second end 110b of the second connecting plate 112 along the corresponding second direction.

[0081] When assembling the first radiator 100a and the second radiator 100b, the second end 110b of the second connecting plate 112 can be aligned with the first clearance gap 101 of the first end 110a of the first connecting plate 111. The second connecting plate 112 is moved along the first direction (at this time, the first direction of the first connecting plate 111 and the second connecting plate 112 is the same) until the first end 110a of the second connecting plate 112 enters the first clearance gap 101, and at the same time, the second end 110b of the first connecting plate 111 enters the second clearance gap 102, thereby realizing the cross assembly of the first connecting plate 111 and the second connecting plate 112.

[0082] exist Figures 1 to 3 In the embodiment shown, the radiator assembly 10 includes two radiators (a first radiator 100a and a second radiator 100b), so it is only necessary to cross-assemble the first connecting plate 111 and the second connecting plate 112.

[0083] If the radiator assembly 10 includes three or more (e.g., four) radiators, then the connecting plates of the other radiators besides the first and second radiators need to be cross-assembled.

[0084] In this embodiment, a first clearance gap 101 is provided at the first end 110a of the first connecting plate 111, and a second clearance gap 102 is provided at the second end 110b of the second connecting plate 112. The first end 110a of the second connecting plate 112 cooperates with the first clearance gap 101, and the second end 110b of the first connecting plate 111 cooperates with the second clearance gap 102, thereby facilitating the cross-assembly of the first connecting plate 111 and the second connecting plate 112. The assembly method is simple and the structure is stable.

[0085] Please combine Figures 4 to 7 In some embodiments, the bent plate 121 extends in an arc shape or a straight line along the circumference of the radiator assembly 10.

[0086] exist Figure 4 and Figure 5 In the illustrated embodiment, the radiator assembly 10 includes two radiators 100, namely a first radiator 100a and a second radiator 100b. The connecting plate 110 of the first radiator 100a is a first connecting plate 111, and the two bent plates 121 of the first radiator 100a are two first bent plates 121a. The connecting plate 110 of the second radiator 100b is a second connecting plate 112, and the two bent plates 121 of the second radiator 100b are two second bent plates 121b. Figure 4 In the illustrated embodiment, the first bent plate 121a and the second bent plate 121b extend in a straight line along the circumference of the radiator assembly 10. Figure 5 In the illustrated embodiment, the first bent plate 121a and the second bent plate 121b extend in an arc shape along the circumference of the radiator assembly 10.

[0087] exist Figure 6 and Figure 7 In the illustrated embodiment, the radiator assembly 10 includes three radiators 100: a first radiator 100a, a second radiator 100b, and a third radiator 100c. The connecting plate 110 of the third radiator 100c is a third connecting plate 113, and the two bent plates 121 of the third radiator 100c are two third bent plates 121c. Figure 6 In the illustrated embodiment, the first bent plate 121a, the second bent plate 121b, and the third bent plate 121c extend in a straight line along the circumference of the radiator assembly 10. Figure 5 In the illustrated embodiment, the first bent plate 121a, the second bent plate 121b, and the third bent plate 121c extend in an arc shape along the circumference of the radiator assembly 10.

[0088] In this embodiment, multiple bending plates 121 extend in an arc or straight line along the circumference of the radiator assembly 10, which can flexibly adapt to different antenna design requirements, ensure that the slotted vibrators 1211 on the bending plates 121 are orderly distributed in the circumference, and ensure that the radiator assembly 10 achieves omnidirectional radiation function.

[0089] In one embodiment, each connecting plate 110 intersects at its midpoint in the width direction, thereby forming a cross center. The multiple connecting plates 110 that are cross-assembled intersect evenly around the cross center.

[0090] For example, in Figure 4 and Figure 5 In the middle, the two connecting plates 110 intersect perpendicularly. Figure 6 and Figure 7 In the middle, the acute angle between adjacent connecting plates 110 is 60°.

[0091] Multiple connecting plates 110 are evenly intersected around the intersection center, so that the bent plates 121 connected to each connecting plate 110 can be evenly arranged around the circumference of the radiator assembly 10, making the distribution of the slotted oscillators 1211 on the bent plates 121 more uniform. At the same time, the connecting plates 110 are evenly distributed around the circumference of the radiator assembly 10, with good symmetry.

[0092] Please refer to Figures 8 to 11 One embodiment of this application provides a method for manufacturing a radiator 100, comprising the following steps:

[0093] S100: Fabricate a preliminary radiator 100', wherein the preliminary radiator 100' includes a connecting plate 110 that is coplanar with each other and two plates 120 to be bent. The two ends of the connecting plate 110 along the first direction are a first end 110a and a second end 110b, respectively. From the first end 110a to the second end 110b, the width of the connecting plate 110 gradually narrows from both sides to the middle. The width direction of the connecting plate 110 is the second direction. The two plates 120 to be bent are both located on the side of the first end 110a away from the second end 110b, and one end of the two plates 120 to be bent is connected to the two ends of the connecting plate 110 along the second direction. Each plate 120 to be bent is provided with a slit vibrator 1211.

[0094] Specifically, the connecting plate 110 and the two plates to be bent 120 are integrally formed structures.

[0095] Specifically, the connecting plate 110 in the radiator prototype 100' is used to form the connecting plate 110 in the radiator 100, and the bending plate 120 in the radiator prototype 100' is used to form the bending plate 121 and the supporting narrow plate 122 in the radiator 100.

[0096] The radiator prototype 100' with the slotted vibrator 1211 can be manufactured in one piece using a stamping process. Alternatively, a connecting plate 110 without the slotted vibrator 1211 and two plates 120 to be bent can be manufactured first, and then the slotted vibrator 1211 can be machined on the plates 120 to be bent.

[0097] S200: The two plates 120 to be bent are bent respectively, so that each plate 120 to be bent forms a bent plate 121 and a supporting narrow plate 122 set at an angle. The supporting narrow plate 122 is coplanar with the connecting plate 110. The side 114 of the supporting narrow plate 122 along the second direction is connected to one side of the corresponding bent plate 121. The two bent plates 121 are set opposite to each other and are located on both sides of the plane of the connecting plate 110 along the third direction. The gap vibrator 1211 is located on the bent plate 121.

[0098] After step S100, the two plates 120 to be bent are bent respectively, as shown in the following reference. Figure 8 At the position indicated by the dashed line, after bending the plate 120 to be bent, each plate 120 will form a bent plate 121 and a supporting narrow plate 122 arranged at an angle. The supporting narrow plate 122 remains coplanar with the connecting plate 110. The bent plate 121 is bent relative to the supporting narrow plate 122, so that the two bent plates 120, after being bent, result in two bent plates 121 arranged opposite each other and located on opposite sides of the plane containing the connecting plate 110 along a third direction.

[0099] The method for manufacturing the radiator 100 described above involves first creating a preliminary radiator prototype 100', which includes a connecting plate 110 that is coplanar with each other and two plates 120 to be bent. Each plate 120 is provided with a slot vibrator 1211. The two plates 120 are then bent separately to form a bent plate 121 and a supporting narrow plate 122 arranged at an angle, thereby obtaining the radiator 100. The method for manufacturing the radiator 100 is simple and easy to process. When manufacturing the radiator assembly 10, multiple radiators 100 can be manufactured using this method, and then the connecting plates 110 of the multiple radiators can be cross-assembled. The resulting radiator assembly 10 can replace the function of the upper cone structure of a traditional dual-polarized omnidirectional antenna, and the processing technology is simple and easy to process.

[0100] In some embodiments, the connecting plate 110, the two bent plates 121, and the two supporting narrow plates 122 in the same radiator 100 are integrally formed structures.

[0101] Specifically, the radiator 100 of this embodiment can be manufactured using the above-described method for manufacturing the radiator 100. First, a preliminary radiator product 100' is manufactured using processes such as stamping, resulting in a single-piece structure of the connecting plate 110 and the plate to be bent 120. Then, the plate to be bent 120 is bent to form a bent plate 121 and a supporting narrow plate 122. Therefore, the connecting plate 110, the two bent plates 121, and the two supporting narrow plates 122 are a single-piece structure. The manufacturing process of the radiator 100 in this way is simple and convenient.

[0102] Please refer to Figure 2 and Figure 3 , Figures 8 to 11 In some embodiments, the radiator 100 further includes two support narrow plates 122, both of which are located on the side of the first end 110a away from the second end 110b, and one end of each of the two support narrow plates 122 is connected to the two ends of the connecting plate 110 along the second direction, and the length direction of the support narrow plates 122 is along the first direction.

[0103] Two supporting narrow plates 122 correspond one-to-one with two bending plates 121, and the side edge 114 of the supporting narrow plate 122 along the second direction is connected to one side of the corresponding bending plate 121.

[0104] In this embodiment, the narrow support plate 122 is connected to the bending plate 121 to facilitate the support of the bending plate 121, thereby indirectly connecting the bending plate 121 to the connecting plate 110.

[0105] When manufacturing the radiator 100 using the manufacturing method of the radiator 100 in the foregoing embodiment, by bending the plate to be bent 120, a support narrow plate 122 and a bending plate 121 that are connected to each other and set at an angle can be formed, thereby facilitating the manufacturing of the radiator 100.

[0106] Please refer to Figure 2 and Figure 3 , Figures 8 to 11 In some embodiments, the two support narrow plates 122 are connected to the corresponding bent plates 121 on the sides of the two support narrow plates 122 that are far apart from each other along the second direction.

[0107] Please refer to Figures 12 to 14 In other embodiments, the two support narrow plates 122 are respectively connected to the corresponding bent plates 121 on the side that is close to each other along the second direction.

[0108] Please refer to Figure 8 In some embodiments, the connecting plate 110 is arc-shaped along the extension direction of the side edges 114 on both sides of the second direction.

[0109] Please refer to Figure 9 In some embodiments, the connecting plate 110 is linear in the extension direction of the side edges 114 on both sides of the second direction.

[0110] Please refer to Figure 10 and Figure 11 In some embodiments, the side edges 114 of the connecting plate 110 along the second direction include multiple (e.g., two or three) extension segments 114a connected in sequence, and the extension direction of any one extension segment 114a is straight or arc-shaped.

[0111] For details, please refer to Figure 10 Each extension segment 114a in side 114 extends in a straight line. Please refer to... Figure 11 One of the extension segments 114a in the side 114 extends in an arc shape, while the other extension segment 114a extends in a straight line.

[0112] In other embodiments, the extension direction of the side 114 may also be other curves or broken lines, and there is no limitation thereto.

[0113] Please combine Figure 6 and Figure 7 ,as well as Figures 12 to 14There are three radiators 100: a first radiator 100a, a second radiator 100b, and a third radiator 100c. The first end 110a of the connecting plate 110 (i.e., the third connecting plate 113) of the third radiator 100c has a third clearance gap 103, and the second end 110b has a fourth clearance gap 104. The second end 110b of the first connecting plate 111 mates with the fourth clearance gap 104, and the first end 110a of the second connecting plate 112 mates with the third clearance gap 103.

[0114] Figures 12 to 14 The figures shown are a first radiator prototype 100a' for forming a first radiator 100a, a second radiator prototype 100b' for forming a second radiator 100b, and a third radiator prototype 100c' for forming a third radiator 100c.

[0115] Combination Figures 12 to 14 It is understandable that when the three radiators 100 are cross-assembled, the second end 110b of the third connecting plate 113 can be aligned with the first clearance gap 101 of the first end 110a of the first connecting plate 111. The third connecting plate 113 is then moved along the first direction (at this time, the first direction of the first connecting plate 111 and the third connecting plate 113 is the same) until the first end 110a of the third connecting plate 113 enters the first clearance gap 101, while the second end 110b of the first connecting plate 111 enters the fourth clearance gap 104, thus achieving the cross-assembly of the first connecting plate 111 and the third connecting plate 113. At this time, the third clearance gap 103 of the third connecting plate 113 and the first clearance gap 101 of the first connecting plate 111 are both located in the intersection area of ​​their first ends 110a.

[0116] Next, align the second end 110b of the second connecting plate 112 with the intersection area of ​​the first end 110a of the third connecting plate 113 and the first end 110a of the first connecting plate 111, that is, the intersection of the third clearance gap 103 and the first clearance gap 101. Move the second connecting plate 112 along the first direction, and the second clearance gap 102 of the second end 110b of the second connecting plate 112 can move along the intersection area until the first end 110a of the second connecting plate 112 is located in the third clearance gap 103 and the first clearance gap 101, and the second end 110b of the third connecting plate 113 and the second end 110b of the first connecting plate 111 are located in the second clearance gap 102.

[0117] In this embodiment, the number of radiators 100 is set to three. The first end 110a of the connecting plate 110 of the third radiator 100c is provided with a third clearance gap 103, and the second end 110b is provided with a fourth clearance gap 104.

[0118] The second end 110b of the first connecting plate 111 engages with the fourth clearance gap 104, and the first end 110a of the second connecting plate 112 engages with the third clearance gap 103, thereby facilitating the cross-assembly of the three radiators 100. This allows the bending plates 121 of each radiator 100 to be arranged more densely around the radiator assembly 10, making the distribution of the slot oscillators 1211 on the bending plates 121 more reasonable and numerous, and further optimizing the omnidirectional radiation characteristics in the horizontal direction.

[0119] Please combine Figure 15 and Figure 16 In some embodiments, the radiator assembly 10 further includes a power divider 200 mounted on the radiator 100. The power divider 200 is located within the space enclosed by each of the bending plates 121, and the slot vibrators 1211 on each of the bending plates 121 are electrically connected to the power divider 200.

[0120] Specifically, the power divider 200 can be fixedly connected to the radiator assembly 10. For example, by providing a flange at the first end 110a of the connecting plate 110, the power divider 200 can be fixed to the flange, thereby achieving reliable installation of the power divider 200.

[0121] In this embodiment, the power divider 200 is installed on the radiator 100 and placed in the space enclosed by each bending plate 121. The slot vibrators 1211 on each bending plate 121 are electrically connected to the power divider 200 to realize the signal distribution of each slot vibrator 1211, ensuring the stable transmission of horizontal polarization signals, thereby enabling the radiator assembly 10 to realize the omnidirectional radiation function.

[0122] Please combine Figure 15 and Figure 16 In some embodiments, the radiator assembly 10 further includes multiple radio frequency coaxial cables 300, and the power divider 200 includes multiple output ports 201. The slot vibrator 1211, the radio frequency coaxial cables 300, and the output ports 201 are arranged in a one-to-one correspondence, and the slot vibrator 1211 is electrically connected to the output port 201 through the corresponding radio frequency coaxial cable 300.

[0123] By making the slot vibrator 1211, the radio frequency coaxial cable 300 and the output port 201 of the power divider 200 correspond one-to-one, the slot vibrator 1211 is electrically connected to the output port 201 through the corresponding radio frequency coaxial cable 300, which facilitates the precise signal distribution of each slot vibrator 1211 by the power divider 200, ensures stable transmission of horizontally polarized signals, and facilitates the radiator assembly 10 to perform omnidirectional radiation.

[0124] Please refer to Figure 16In some embodiments, the slot vibrator 1211 is formed by a slot opened in the bent plate 121, the slot having opposing first sidewalls 1212 and second sidewalls 1213. The slot vibrator 1211 can be electrically connected to one end of the corresponding radio frequency coaxial cable 300 by electrically connecting the inner conductor 310 of the corresponding radio frequency coaxial cable 300 to the first sidewall 1212 and the outer conductor 320 to the second sidewall 1213.

[0125] Please combine Figure 15 and Figure 16 In some embodiments, the radiator assembly 10 further includes a horizontally polarized feed cable 400, and the power divider 200 includes an input port 202. One end of the horizontally polarized feed cable 400 is electrically connected to the input port 202, and the horizontally polarized feed cable 400 passes between two adjacent connecting plates 110. The other end of the horizontally polarized feed cable 400 is used for electrical connection to a horizontally polarized radio frequency signal source.

[0126] By electrically connecting the horizontally polarized feed cable 400 to the input port 202 of the power divider 200, and electrically connecting the other end of the horizontally polarized feed cable 400 away from the input port 202 to a horizontally polarized radio frequency signal source, external horizontally polarized signals can be transmitted to the power divider 200. Furthermore, by passing the horizontally polarized feed cable 400 between two adjacent connecting plates 110, the other end of the horizontally polarized feed cable 400 away from the input port 202 can extend out of the radiator 100 for electrical connection to the horizontally polarized radio frequency signal source.

[0127] Please combine Figures 8 to 11 In some embodiments, the slit oscillator 1211 can be in the shape of a long rectangle, a butterfly, or other shapes, and there are no restrictions on this.

[0128] In some embodiments, the number of slot oscillators 1211 on a single bent plate 121 may be one, two or more.

[0129] In one embodiment, all the bent plates 121 on the radiator assembly 10 form a centrally symmetrical structure, which allows the slot oscillators 1211 on the bent plates 121 to be distributed more evenly along the circumference of the radiator assembly 10. The evenly distributed slot oscillators 1211 can enable the entire slot oscillator array to generate a balanced horizontally polarized signal and have good omnidirectional signal radiation characteristics.

[0130] In one embodiment, the power divider 200 adopts an equal amplitude and in phase design, and all radio frequency coaxial cables 300 are also in phase, thereby enabling equal amplitude and in phase feeding of each slot element 1211, so that the antenna array composed of all slot elements 1211 generates a balanced horizontally polarized radiation signal and has good omnidirectional radiation characteristics.

[0131] Please combine Figure 15 and Figure 16 An embodiment of this application also provides a dual-polarized omnidirectional antenna, including: a reflector 20, a vertically polarized feed cable 30, and a radiator assembly 10 of any of the above embodiments. The reflector 20 is located on the side of the connecting plate 110 away from the bending plate 121. The inner conductor 31 of the vertically polarized feed cable 30 is electrically connected to the radiator 100, and the outer conductor 32 of the vertically polarized feed cable 30 is electrically connected to the reflector 20.

[0132] A vertically polarized antenna is formed by electrically connecting the inner conductor 31 of the vertically polarized feed cable 30 to the radiator 100 and the outer conductor 32 of the vertically polarized feed cable 30 to the reflector 20, thus enabling the transmission and radiation of vertically polarized signals. This vertically polarized antenna also exhibits circumferential symmetry, thereby generating a balanced vertically polarized signal and possessing excellent omnidirectional signal radiation characteristics. Combined with the horizontal polarization function of the radiator assembly 10, this allows the dual-polarized omnidirectional antenna to possess complete dual-polarization characteristics and omnidirectional radiation capability.

[0133] One embodiment of this application also provides a dual-polarized omnidirectional antenna, including: a conical element, a vertically polarized feed cable 30, and a radiator assembly 10 as described in any of the above embodiments. The conical element is located on the side of the connecting plate 110 away from the bending plate 121. The outer diameter of the conical element gradually increases along the direction from the first end 110a to the second end 110b. The inner conductor 31 of the vertically polarized feed cable 30 is electrically connected to the radiator 100, and the outer conductor 32 of the vertically polarized feed cable 30 is electrically connected to the conical element. The end of the vertically polarized feed cable 30 away from the radiator 100 is used for electrical connection to a vertically polarized radio frequency signal source.

[0134] The specific structure of the conical vibrator can be referenced from the lower conical structure of a traditional dual-polarized omnidirectional antenna.

[0135] The vertically polarized feed cable 30 is electrically connected to the radiator 100 via its inner conductor 31, and to the conical dipole via its outer conductor 32, thereby enabling the transmission and radiation of vertically polarized signals. Simultaneously, this vertically polarized antenna exhibits circumferential symmetry, thus generating a balanced vertically polarized signal and possessing excellent omnidirectional signal radiation characteristics. Combined with the horizontal polarization function of the radiator assembly 10, this allows the dual-polarized omnidirectional antenna to possess complete dual-polarization characteristics and omnidirectional radiation capability.

[0136] The aforementioned dual-polarized omnidirectional antenna has a radiator assembly 10 that can replace the upper cone structure of a traditional dual-polarized omnidirectional antenna, and its manufacturing process is simple and easy to manufacture.

[0137] An embodiment of this application also provides a method for manufacturing a radiator assembly 10, comprising: manufacturing a plurality of radiators 100 by the method for manufacturing radiators 100 in any of the above embodiments; and assembling the connecting plates 110 of the plurality of radiators 100 in a cross-sectional manner with their respective width directions as the intersection area, so that the bending plates 121 of the plurality of radiators 100 are arranged sequentially around the circumference of the radiator assembly 10.

[0138] In the above-mentioned method for manufacturing the radiator assembly 10, the method for manufacturing the radiator 100 is simple and easy to process. When manufacturing the radiator assembly 10, multiple radiators 100 can be manufactured first, and then the connecting plates 110 of the multiple radiators can be cross-assembled. The resulting radiator assembly 10 can replace the function of the upper cone structure of the traditional dual-polarized omnidirectional antenna, and the manufacturing process is simple and easy to process.

[0139] An embodiment of this application also provides a method for manufacturing a dual-polarized omnidirectional antenna, including the method for manufacturing the radiator assembly 10 of the above embodiment.

[0140] The above-described method for manufacturing a dual-polarized omnidirectional antenna is simple and easy to manufacture, with minimal processing difficulty. When manufacturing the radiator assembly 10, multiple radiators 100 can be fabricated first, and then the connecting plates 110 of these multiple radiators can be cross-assembled. This allows the radiator assembly 10 to replace the function of the upper cone structure in a traditional dual-polarized omnidirectional antenna, and the manufacturing process is simple and easy to manufacture.

[0141] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0142] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
