Description

Technical Field

[0001] This invention relates to the field of antenna communication technology, and in particular to a radiating element and antenna. Background Technology

[0002] The radiating element is the core component of a base station antenna, responsible for transmitting and receiving electromagnetic waves. It is the decisive part for the antenna's proper functioning, and its design directly determines the antenna's radiation performance. Currently, radiating elements are typically manufactured using die-casting or similar methods, while the feed network usually uses coaxial cables. To weld the coaxial cable to the radiating element, the outer conductor of the coaxial cable needs to be soldered to the element. Therefore, electroplating is required on the surface of the radiating element, which not only increases material costs but also affects production efficiency and is environmentally unfriendly. Summary of the Invention

[0003] Therefore, it is necessary to provide a radiating unit and antenna that can achieve electroplating-free operation and has a more environmentally friendly production process.

[0007] Four radiating arms are disposed on an insulating base. Each radiating arm has a forked notch extending from one end of the radiating arm away from the insulating base to the other end closer to the insulating base, so as to divide the radiating arm into a first functional arm and a second functional arm. The first functional arm and the second functional arm of the same radiating arm are electrically connected. In each pair of adjacent radiating arms, the first functional arm of one radiating arm and the second functional arm of the other radiating arm are adjacent to each other and are electrically connected through a radiating strip line on the first circuit board.

[0020] In one embodiment, the second circuit board is further provided with pads, which are soldered to the connecting cables and are located on the same side surface of the second circuit board as the power divider line.

[0021] The power divider line includes an output terminal, with the pads located on the side of the output terminal near the insulating base.

[0022] In one embodiment, the number of second circuit boards is four;

[0023] The second circuit board with its pads located at one end in the first direction is defined as a power distribution board, and the second circuit board with its pads located at the other end in the first direction is defined as a power distribution board. The first direction is parallel to the second circuit board and perpendicular to the axis.

[0024] Of the four radiating arms, two of them are connected to a second circuit board that is a power divider, while the other two are connected to a mirror power divider.

[0025] In one embodiment, each radiating arm has a support arm at its end facing the insulating base, and the support arm is connected to the insulating base.

[0026] In one embodiment, the insulating base is constructed as a ring, and the support arm corresponding to each radiating arm is supported on the insulating base. The outline of the support arm facing the axis in the projection on the first plane partially coincides with the inner outline of the projection of the insulating base on the first plane, and the first plane is perpendicular to the axis.

[0027] In one embodiment, adjacent support arms are spaced apart; or

[0028] Of the four sets of radiating arms, the support arms of two adjacent radiating arms are integral pieces, and the support arms of the other two adjacent radiating arms are integral pieces.

[0029] In one embodiment, a first clearance hole is provided on the insulating base at the position corresponding to the connecting cable, and a guide sleeve is provided on the edge of the opening of the first clearance hole;

[0030] The connecting cable passes through the first clearance hole and the guide sleeve.

[0031] In one embodiment, the radiating unit further includes multiple positioning buckles, with the ends of the first and second functional arms of each radiating arm that are away from the insulating base positioned relative to each other by a positioning buckle.

[0032] In one embodiment, the positioning buckle includes a main body and two elastic arms connected to the main body. Slots are provided on both sides of the main body in opposite directions. The first functional arm and the second functional arm of the same radial arm are respectively inserted into the two slots.

Furthermore, each radiating arm is electrically connected to a corresponding second circuit board, and the power divider lines on each second circuit board are electrically connected to a corresponding connecting cable. Thus, each radiating arm is connected to the outside world via connecting cables. In addition, each radiating arm has a forked notch, thereby realizing the electrical function of the radiating unit. On the other hand, since the connecting cables are electrically connected to the power divider lines on the second circuit board, this connection can be achieved without electroplating the radiating unit, saving material costs, making the processing more environmentally friendly, and improving production efficiency.

[0068] The radiating element and antenna of the present application embodiment are described below with reference to the accompanying drawings.

[0069] Figure 1 This is a schematic diagram of the structure of the radiating unit provided in an embodiment of this application. Figure 2 This is an exploded structural diagram of the radiating element provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of the radiating arm in the radiating unit provided in the embodiment of this application. Figure 4 This is a schematic diagram of the structure of the insulating base in the radiating unit provided in the embodiment of this application.

[0070] Reference Figure 1 and Figure 2 The radiation unit 100 provided in this application embodiment includes an insulating base 40, a first circuit board 10, a second circuit board 20, a connecting cable 30, and four radiation arms 50.

[0071] The first circuit board 10 has radiating lines 11, and the second circuit board 20 has power splitting lines 21. Each power splitting line 21 is electrically connected to a corresponding connecting cable 30. Further, four radiating arms 50 are disposed on an insulating base 40. Each radiating arm 50 has a forked notch 501 extending from one end away from the insulating base 40 to the other end closer to the insulating base 40, thus branching the radiating arm 50 into a first functional arm 51 and a second functional arm 52. The first functional arm 51 and the second functional arm 52 of the same radiating arm 50 are electrically connected. In every two adjacent radiating arms 50, the first functional arm 51 of one radiating arm 50 and the second functional arm 52 of the other radiating arm 50 are adjacent and electrically connected through the radiating lines 11 on the first circuit board 10. The first functional arm 51 and the second functional arm 52 of each radiating arm 50 are each electrically connected to a corresponding second circuit board 20.

[0072] In each pair of adjacent radiating arms 50, the first functional arm 51 of one radiating arm 50 and the second functional arm 52 of the other radiating arm 50 are electrically connected via a radiating strip line 11 on a first circuit board 10. This ensures that the first functional arm 51 of one radiating arm 50 and the second functional arm 52 of the other radiating arm 50 are electrically connected to each other. Furthermore, each radiating arm 50 is electrically connected to a corresponding second circuit board 20, and the power divider strip line 21 on each second circuit board 20 is electrically connected to a corresponding connecting cable 30. Thus, each radiating arm 50 is connected to the outside world via the connecting cable 30. In addition, the four radiating arms 50 are arranged around an axis, and each radiating arm 50 has a forked notch 501 on its end face facing away from the insulating base 40, thereby realizing the electrical radiation function of the radiating unit 100. On the other hand, since the connecting cable 30 is electrically connected to the power divider strip line 21 on the second circuit board 20, the connection can be achieved without electroplating the radiating unit 100, which not only saves material costs and makes the processing more environmentally friendly, but also improves production efficiency.

[0073] Combination Figure 2 and Figure 4 The insulating base 40 can be, for example, a thin plate, which serves to insulate and isolate the radiating unit 100 and the reflector 210, effectively ensuring the intermodulation stability of the antenna 200. The insulating base 40 can be a one-piece molded part, which can be integrally molded into an injection mold. The insulating base 40 can be formed into a ring shape corresponding to the radiating unit 100.

[0074] The arrangement of the four radiating arms 50 around an axis means that the four radiating arms 50 are positioned around the same axis, which can be perpendicular to the insulating base 40. In other words, the four radiating arms 50 are arranged in a circle, with each pair of arms facing the other, to achieve the electrical radiation performance of the radiating unit 100. The four radiating arms 50 are connected to the same side of the insulating base 40, for example, all four radiating arms 50 are connected to the upper side of the insulating base 40 (the side away from the reflector).

[0075] In this embodiment, the first circuit board 10 and the second circuit board 20 can be PCB printed circuit boards. The first circuit board 10 is provided with a radiating strip line 11, and the second circuit board 20 is provided with a power dividing strip line 21. By adjusting the power dividing strip line 21 and the radiating strip line 11, the electrical performance of the radiating unit 100 can be adjusted, thereby solving the problem of solidifying the electrical performance of the die-cast radiating element. The radiating strip line 11 can be arranged towards the axis, that is, it is located on the inward side of the first circuit board 10. This application can achieve the adjustment of the electrical performance of the radiating element by adjusting the structure and size of the radiating strip line 11. The radiating strip line 11 can extend along the relative directions of two adjacent first functional arms 51 and second functional arms 52.

[0076] Additionally, refer to Figure 2 The second circuit board 20 is also provided with a solder pad 22, which is soldered to the connecting cable 30 and is located on the same side surface of the second circuit board 20 as the power divider line 21. The power divider line 21 includes an output end, and the solder pad 22 is located on the side of the output end near the insulating base 40.

[0077] Each power splitter line 21 is electrically connected to a corresponding connecting cable 30. In practice, the center conductor of the connecting cable 30 can be soldered to the output end of the power splitter line 21, and the braided layer of the connecting cable 30 can be soldered to the pad 22.

[0078] In this embodiment, each radiating arm 50 is provided with a bifurcated notch 501 extending from one end of the radiating arm 50 away from the insulating base 40 to the other end closer to the insulating base 40. In other words, each radiating arm 50 has a bifurcated notch 501 on the end face away from the insulating base 40 to bifurcate the radiating arm 50 into a first functional arm 51 and a second functional arm 52. The bifurcated notch 501 penetrates the thickness direction of the radiating arm 50 and extends towards the insulating base 40. The electrical radiation performance of the radiating unit 100 can be adjusted by adjusting the size of the bifurcated notch 501, for example by adjusting the extension length and width of the bifurcated notch 501.

[0079] In each pair of adjacent radiating arms 50, the first functional arm 51 of one radiating arm 50 and the second functional arm 52 of the other radiating arm 50 are electrically connected via a radiating strip 11 on a first circuit board 10. In other words, when the first functional arms 51 and second functional arms 52 of each radiating arm 50 are arranged circumferentially, for each pair of adjacent radiating arms 50, the two directly adjacent functional arms are electrically connected via the first circuit board 10. In this way, the pairwise connection of adjacent radiating arms 50 is achieved through a first circuit board 10, thereby constructing the overall basic framework of the radiating unit 100.

[0080] In specific implementation, refer to Figure 2 In two adjacent radiating arms 50, the first functional arm 51 of one radiating arm 50 and the second functional arm 52 of the other radiating arm 50 are both coupled to the radiating strip line 11 on the same first circuit board 10.

[0081] Furthermore, the first functional arm 51 and the second functional arm 52 of the same radiation arm 50 are respectively provided with a first mating part 510 and a second mating part 520, and the first mating part 510 and the second mating part 520 can extend from the first functional arm 51 and the second functional arm 52 respectively.

[0082] The first circuit board 10 includes a first connection region 101 and a second connection region 102 located at its two opposite ends. The radial lines 11 of the first circuit board 10 include a first terminal (not shown) disposed in the first connection region 101 and a second terminal (not shown) disposed in the second connection region 102. In two adjacent radial arms 50, the first mating portion 510 of one radial arm 50 is stacked with the first connection region 101 of one of the first circuit boards 10, thus enabling coupling connection or direct contact electrical connection between the first mating portion 510 and the first terminal of the first connection region 101. The second mating portion 520 of the other radial arm 50 is stacked with the second connection region 102 of the same first circuit board 10, thus enabling coupling connection or direct contact electrical connection between the second mating portion 520 and the second terminal of the second connection region 102. Of course, Figure 2 The following explanation uses a coupled connection as an example. The situation is similar for direct contact, and will not be elaborated here.

[0083] Combination Figure 2 and Figure 3 To facilitate connection, both the first mating part 510 and the second mating part 520 are folded towards the axis relative to the radiating arm 50. Furthermore, in two adjacent radiating arms 50, the first mating part 510 of one radiating arm 50 and the second mating part 520 of the other radiating arm 50 can be arranged parallel to the corresponding first circuit board 10 for easy connection.

[0084] In specific implementation, each radiating arm 50 has a first mating hole 5100 and a second mating hole 5200 on its first mating portion 510 and second mating portion 520, respectively. A first connecting region mating hole 1011 is provided on the first connecting region 101 corresponding to the first mating hole 5100, and a second connecting region mating hole 1021 is provided on the second connecting region 102 corresponding to the second mating hole 5200. Mechanical connection between the first circuit board 10 and the adjacent first functional arm 51 and second functional arm 52 can be achieved by insulating fasteners passing through the corresponding first mating holes 5100 and 1011, and by insulating fasteners passing through the corresponding second mating holes 5200 and 1021. In other words, the first circuit board 10 is detachably connected to the corresponding first functional arm 51 or second functional arm 52 via insulating fasteners.

[0085] Continue to refer to Figure 1 and Figure 2As shown in this embodiment, the number of second circuit boards 20 is four. The four radiating arms 50 include two radiating arms 50 arranged opposite each other along a first direction, and two radiating arms 50 arranged opposite each other along a second direction; the first direction and the second direction intersect; the surfaces of the two oppositely arranged radiating arms 50 that face away from each other are defined as the back surfaces of each radiating arm 50. Each second circuit board 20 is stacked on the back surface of the corresponding radiating arm 50.

[0086] The power divider line 21 on the second circuit board 20 is located on the side surface of the second circuit board 20 opposite to the corresponding radiating arm 50.

[0087] Furthermore, each radiating arm 50 is constructed as an elongated structure extending from the insulating base 40 in a direction away from the insulating base. At least a portion of the extending end of the radiating arm 50 is folded away from the axis to form a folded portion 53. A first circuit board 10 electrically connected to the radiating arm 50 is connected to the folded portion 53 of the radiating arm 50, and a second circuit board 20 electrically connected to the radiating arm 50 is connected to the end of the radiating arm 50 away from the folded portion 53. Thus, when viewed from above, the first circuit board 10 is located outside the second circuit board 20, which facilitates the realization of the electrical functions of the radiating unit 100.

[0088] In practice, the radiating arm 50 can be made of aluminum bent in the middle, which not only achieves lightweighting but also eliminates the need for electroplating on the surface, thus solving the environmental problems caused by electroplating.

[0089] Figure 5 This is a schematic diagram of the structure of the second circuit board 20 in the radiation unit 100 provided in the embodiment of this application.

[0090] Combination Figure 2 and Figure 5 The second circuit board 20 with pads 22 located on one side of the third direction F is defined as power divider board 60, and the second circuit board 20 with pads 22 located on the other side of the third direction F is defined as mirror power divider board 70. The third direction F is parallel to the second circuit board 20 and perpendicular to the axis. Here, the third direction F is actually the tangent direction of a circle centered on the axis.

[0091] Of the four radiating arms 50, two of the radiating arms 50 are connected to a second circuit board 20 which is a power divider board 60, and the other two radiating arms 50 are connected to a second circuit board 20 which is a mirror power divider board 70.

[0092] In this embodiment, the radiating arm 50 and the second circuit board 20 are detachably connected by insulating fasteners. Specifically, in combination with… Figure 3 and Figure 5The second circuit board 20 is provided with a second fixing hole 23, and the radiating arm 50 is provided with a number of third fixing holes 24 corresponding to the position of the second fixing hole 23. Considering that the third fixing holes 24 need to be adapted to the power divider board 60 and the mirror power divider board 70, the number of third fixing holes 24 is more than that of the second fixing holes 23.

[0093] The second circuit board 20 and the radiating arm 50 can be relatively fixed by passing the insulating fastener through the corresponding second fixing hole 23 and third fixing hole 24.

[0094] Combination Figure 2 and Figure 3 Each radiating arm 50 has a support arm 54 at its end facing the insulating base 40, and the support arm 54 is connected to the insulating base 40.

[0095] Furthermore, as mentioned above, the insulating base 40 is constructed as a ring-shaped component, and the support arm 54 corresponding to each radial arm 50 is supported on the insulating base 40. The outline of the support arm 54 on the side facing the axis in the projection on the first plane partially coincides with the inner outline of the projection of the insulating base 40 on the first plane, where the first plane is perpendicular to the aforementioned axis.

[0096] In practice, the support arm 54 is provided with a support arm mating hole 541, and the insulating base 40 is provided with a base mating hole 401 at the corresponding position of the support arm mating hole 541. An insulating fastener can be used to pass through the corresponding support arm mating hole 541 and base mating hole 401 to achieve a mechanical connection between the support arm 54 and the insulating base 40. This allows the radiating arm 50 and the insulating base 40 to be detachably connected via insulating fasteners.

[0097] Furthermore, referring to Figure 2 Alternatively, the support arms 54 can be spaced apart from each other. Or, in the four sets of radiating arms 50, the support arms 54 of two adjacent radiating arms 50 can be a single piece, and the support arms 54 of the other two adjacent radiating arms 50 can be a single piece.

[0098] In this embodiment of the application, combined with Figure 2 and Figure 4 An insulating base 40 has a first clearance hole 41 corresponding to the position of the connecting cable 30, and a guide sleeve 42 is provided on the edge of the opening of the first clearance hole 41. The guide sleeve 42 is located on the side of the insulating base away from the radiating arm 50. The connecting cable 30 passes through the first clearance hole 41 and the guide sleeve 42.

[0099] In this embodiment of the application, the radiation unit 100 further includes a plurality of positioning buckles 80, and the ends of the first functional arm 51 and the second functional arm 52 of each radiation arm 50 that are away from the insulating base 40 are positioned to each other by a positioning buckle 80.

[0100] The positioning buckle 80 can fix the first functional arm 51 and the second functional arm 52 in the radiation arm 50 relative to each other, and prevent the first functional arm 51 and the second functional arm 52 from deforming. At the same time, it ensures the dimensional stability of the functional gap of the radiation unit, that is, the bifurcation notch 501, thereby ensuring the stability of the electrical performance of the radiation unit 100.

[0101] In a specific implementation, the positioning buckle 80 includes a main body 81 and two elastic arms 82 connected to the main body 81. Slots 83 are provided on both sides of the main body 81 in opposite directions. The first functional arm 51 and the second functional arm 52 of the same radial arm 50 are respectively inserted into the two slots 83.

[0102] Two fixed elastic arms 82 are respectively engaged with the first functional arm 51 and the second functional arm 52. For example, each of the two elastic arms 82 is provided with a locking part 821, and the first functional arm 51 and the second functional arm 52 are provided with locking holes 822 at positions corresponding to the locking parts 821. The above-mentioned locking engagement is achieved by the cooperation of the locking parts 821 and the corresponding locking holes 822.

[0103] refer to Figure 1 and Figure 2 Four identical positioning buckles 80 are respectively installed on the four corresponding radial arms 50. For the installation of a single positioning buckle 80, the part of the main body 81 located between the two slots 83 slides into the bifurcation notch 501 of the radial arm 50 and slides downward along the bifurcation notch 501. The two locking parts 821 on the two elastic arms 82 press against the first functional arm 51 and the second functional arm 52, pushing the elastic arm 82 up and deforming it. When the locking part 821 slides to the position of the corresponding locking hole 822, the locking part 821 locks into the locking hole 822, and the elastic arm 82 returns to its shape.

[0104] Furthermore, the ends of the first functional arm 51 and the second functional arm 52 near the insulating base are connected to each other.

[0107] The insulating base 40 of the radiating unit 100 is connected to the reflector 210.

[0108] For example, a reflector mating hole 211 is provided on the reflector 210 at the position corresponding to the base mating hole 401. An insulating fastener passes through the support arm mating hole 541, the base mating hole 401 and the reflector mating hole 211 to fix the support arm 54, the insulating base 40 and the reflector 210 relative to each other.

[0109] In addition, a second clearance hole 212 is provided on the reflector plate 210 at the position corresponding to the first clearance hole 41, so that the connecting cable 30 can pass through. In other words, the connecting cable 30 passes through the first clearance hole 41 and the second clearance hole 212.

[0110] The antenna 200 also includes an antenna cover 220, which has a cavity inside, where the radiating element 100 and the reflector 210 are located.

[0111] It should be noted that when there are multiple radiating elements 100, the multiple radiating elements 100 are arranged in a linear array on the reflector 210. The reflector 210 is provided at a certain height from the bottom wall of the accommodating cavity of the antenna cover 220 to ensure the installation height of the radiating element and realize the normal radiation performance of the radiating element.
