[0049] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following will illustrate examples of implementation of the present application with reference to the accompanying drawings. The accompanying drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other accompanying drawings and other implementations can be obtained based on these drawings without creative work. Adjustments and improvements made without departing from the concept of the present application are all within the scope of protection of the present application.

[0050] In order to simplify the drawings, each figure only schematically shows the parts related to the embodiments, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only a part of the components with the same structure or function is schematically drawn, and there may be more or less components with the same structure or function in reality.

[0051] In this application, unless otherwise clearly specified and limited, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe associated objects, and cannot be understood as indicating or implying the relative importance or order between associated objects; in addition, they do not represent the number of associated objects. "Multiple" includes two or more, and other quantifiers are similar. " / " is used to describe the relationship between associated objects, which indicates the "or" relationship between associated objects. "And / or" is used to describe the relationship between associated objects, which includes any combination relationship between associated objects, such as "a and / or b" includes: "alone a", "alone b", or "a and b". "One or more" or "at least one" in multiple objects refers to any object or any combination of multiple objects, such as "one or more of a1, a2, a3" or "at least one of a1, a2, a3" includes: "alone a1", "alone a2", "alone a3", "a1 and a2", "a1 and a3", "a2 and a3" or "a1, a2 and a3".

[0052] In smart antennas, the calibration network is the first-level component of the smart antenna, which is used to collect amplitude and phase information of different ports in the smart antenna to compensate for the amplitude and phase deviations generated when the base station processor and the antenna are connected. In the prior art, the power division network and directional coupler included in the calibration network are often set on the same layer of the dielectric board, and the directional coupler needs to be welded to the coaxial cable. Such a layout is not conducive to the visualization of welding during the antenna production process. At the same time, other welding forms are likely to cause the antenna to be too large, affecting the flexibility of the antenna equipment.

[0053] The embodiment of the present application designs the power division network and the directional coupler to be incompletely coplanar, which makes it easier to connect the directional coupler and the coaxial cable connected to it during the overall welding process. At the same time, the volume of the calibration network is not enlarged, which is beneficial to the miniaturization of the antenna device.

[0054] The following is a description with reference to the accompanying drawings:

[0055] Please refer to Figure 1 , which shows an example structural diagram of a calibration network component provided in some embodiments of the present application. Figure 1 As shown, the calibration network component 100 at least includes: a dielectric plate 110 and a first power division network group 121, a second power division network group 131 and a directional coupler 132 arranged on the dielectric plate 110;

[0056] The first power division network group 121 is disposed on the first surface 120 of the dielectric plate 110, and the second power division network group 131 and the directional coupler 132 are disposed on the second surface 130 of the dielectric plate 110;

[0057] The output end of the first power division network group 121 is connected to the input end of the second power division network group 131 , and the output end of the second power division network group 131 is connected to the directional coupler 132 .

[0058] In the present application, the power division network of the calibration network component is divided into two parts, one part of which is the first power division network group 121 on the first surface 120 of the dielectric plate 110, and the other part of which is the second power division network group 131 and the directional coupler 132 arranged on the second surface 130 of the dielectric plate 110. Different from the traditional design method in which the power division network and the directional coupler 132 are all arranged on one side of the dielectric plate 110, the space of the dielectric plate 110 can be fully utilized, making the entire calibration network more compact, thereby realizing a smaller size design. The power division network has multiple levels, and the first power division network group 121 and the second power division network group 131 are distributed on different surfaces of the dielectric plate 110, which can reduce the mutual inductance and crosstalk effects between adjacent power division networks of different levels, improve the performance and stability of the power division network, and reduce interference during signal transmission. The type of the dielectric plate 110 can be a printed circuit board (i.e., PCB board), a flexible circuit board (i.e., FPC), a ceramic circuit board, a rigid-flexible board, etc., which are arranged according to specific application scenarios and design requirements, and are not specifically limited here. The calibration network components realized by the above structure are all within the protection scope of this application. The two groups of power division networks are distributed on both sides of the dielectric plate 110 to simplify the wiring design. The input and output of the first power division network group 121 on the first side 120 and the second power division network group 131 on the second side 130 are connected, and the connection method can be connected by vias. On the one hand, it is easier to wire on the dielectric plate 110, better control the signal transmission path, and reduce the length and loss of the transmission line. On the other hand, it is more flexible to adjust the layout of power division networks of different levels to meet different antenna designs and technical requirements. At the same time, conductors can also be used for electrical connection to achieve the above functions and purposes. Among them, the first side 120 can be the back side of the dielectric plate, and the second side 130 can be the front side of the dielectric plate. Under this layout, the directional coupler 132 on the second side 130 can be convenient for welding and installation when connected to components such as coaxial cables, thereby improving production and equipment maintenance efficiency. The first side 120 can be the front side of the dielectric plate, and the second side 130 can be the back side of the dielectric plate, thereby improving the flexibility of the layout of each component and wiring in the calibration network component.

[0059] In the first power division network group 121, a multi-level power division network can be set, for example, including two-level power division networks, wherein each level of power division network includes one or more power division networks, for example, the first level of power division network includes one power division network, and the second level of power division network includes two power division networks. The power division network in the first level of power division network can include two output ports, and they are respectively connected to the input ports of the two power division networks in the second level of power division network to realize the power division network construction. In the second power division network group 131, one or more levels of power division networks can also be set, for example, including a first level of power division network, which includes four power division networks, and the input port of each power division network is connected to the multiple output ports of the last level of power division network in the first power division network group 121. The input port of the power division network and the multiple output ports of the last level of power division network in the first power division network group 121 can be connected through vias to achieve a simpler wiring layout, or a conductor can be used for electrical connection to achieve a more flexible wiring design. The type and structure of the power division network can be one or more of a balanced power division network, an unbalanced power division network, a multi-way distributor or a bandpass power division network. For example, the power division network adopts a Wilkinson Power Divider structure in the balanced power division network type to achieve equal power distribution and phase matching.

[0060] On the second surface 130 of the dielectric plate 110, the directional coupler 132 is connected to the second power division network group 131, wherein the number of directional couplers 132 matches the number of output ports of the last level power division network of the second power division network group 131, and they are connected accordingly, and cooperate to realize the calibration function of the smart antenna.

[0061] Please refer to Figure 2 , which shows an example structural diagram of another calibration network component provided in some embodiments of the present application. Figure 2 As shown, the calibration network component 200 further includes:

[0062] The first network floor 233 is disposed on the second surface 230 of the dielectric board 210 , and the first power division network group 221 is connected to the first network floor 233 .

[0063] The second network floor 222 is disposed on the first surface 220 of the dielectric board 210 , and the second power division network group 231 is connected to the second network floor 222 .

[0064] The first network floor 233 is connected to the second network floor 222 .

[0065] In the present application, the second network floor 222 of the first power division network group 221 and the second power division network group 231 are placed on the same layer of the first surface 220 of the dielectric board 210, and the first network floor 233 of the second power division network group 231 and the first power division network group 221 are placed on the same layer of the second surface of the dielectric board 210, and the network floors of the first surface 220 and the second surface 230 of the dielectric board 210 can be connected through vias to improve the continuity of the grounding current of the two floors, or they can be electrically connected by conductors. At the same time, the floors of the two power division network groups are not on the same layer of the dielectric board as their corresponding power division network groups, which can reduce the interference of the power division network to the ground: the grounding plate of the power division network is not on the same surface as itself, which can reduce the interference of the ground loop conducted by the signal routing board of the power division network, which helps to improve the signal purity and anti-interference ability of the power division network, while improving the signal integrity and reducing signal distortion and loss.

[0066] In some implementations, the first power division network group includes multiple levels of first power division networks, wherein the Nth level of the first power division network includes 2 (N-1) A first power distribution network;

[0067] The first power division network includes: a first output port, a second output port and a first input port. The first output port is connected to the first input port of a first power division network of the next level, and the second output port is connected to the first input port of another first power division network of the next level.

[0068] In order to achieve more detailed power distribution in the antenna and enhance the flexibility of the system, multiple levels of first power division networks can be set in the first power division network group. For example, there are two levels of first power division networks in the first power division network group. Then, based on the content of the above embodiment, the first-level power division network has 1 first power division network, and the second-level power division network has 2 first power division networks. The two output ports of the first-level first power division network are respectively connected to the input ports of the two first power division networks of the second level, and together constitute the first power division network. The present application does not limit the number of levels of the first power division network group, which can be 1, 2, 3, or 4 levels. For example, when the number of levels is 3, the first-level power division network has 1 first power division network, the second-level power division network has 2 first power division networks, and the third-level power division network has 4 first power division networks, and so on, which will not be elaborated here.

[0069] In some embodiments, the second power division network group includes: a plurality of second power division networks, the number of the second power division networks being determined based on the number of first output ports of the last level first power division network in the first power division network group; the second power division network including: a third output port, a fourth output port, and a second input port;

[0070] The third output port and the fourth output port are respectively connected to the input ends of the corresponding directional couplers.

[0071] The number of second power division networks in the second power division network group needs to match the number of output ports of the last level first power division network in the first power division network group, so as to achieve the integrity and balance of the power distribution process. For example, if the first power division network group has two levels of first power division networks, then the last level of the first power division network includes two first power division networks and four first output ports, then in the second power division network group, the first level of the second power division network includes four second power division networks, and its input port is connected to the output port of the last level of the first power division network group of the first power division network group, forming a complete power division network structure of the calibration network component.

[0072] At the same time, since the first power division network group and the second power division network group belong to two sides of the dielectric board, the first output port of the last-level first power division network in the first power division network group can be connected to the second input end of a second power division network in the second power division network group through a via; the second output port of the last-level first power division network is connected to the second input end of another second power division network in the second power division network group through a via.

[0073] In some embodiments, the calibration network component further includes: a first resistor, one end of the first resistor is connected to the first output port, and the other end of the first resistor is connected to the second output port.

[0074] In the present application, the first power division network in the first power division network group can distribute the input signal equally or unequally to the multiple output ports it includes, and maintain the same output phase. When a first resistor is set between the first output port and the second output port of the first power division network, the resistor acts as an isolation resistor, which increases the isolation of the first power division network on the one hand. The isolation between the two output ports mainly depends on the resistance value between the two output ports. Adding the first resistor can increase the impedance difference between the two output ports, thereby improving the isolation and preventing the signal on one output port from affecting the other output port. The setting of the first resistor can reduce the reflection and interference between the first output port and the second output port, thereby reducing the harmonics and stray signals in the system, preventing nonlinear distortion of the signal, and improving the linearity and bandwidth of the system.

[0075] Please refer to Figure 3 , which shows an example structural diagram of a directional coupler in a calibration network component provided in some embodiments of the present application. Figure 3 As shown, the directional coupler 310 includes a first part 311 and a second part 312 ; the first end of the first part 311 is connected to the output end of the second power division network group 320 , and the second end of the first part 311 is grounded; the second part 312 is coupled to the first part 311 .

[0076] Meanwhile, in the second part 312, a convex step is symmetrically arranged inwardly at position A near the output end of the second part 312, and a convex step is symmetrically arranged inwardly at position B near the input end of the second part 312. The inwardly symmetrical convex step design can improve the impedance matching performance of the input port, achieve better impedance matching, thereby reducing the matching loss at the input port or the output port, and improving the overall performance of the system.

[0077] In some embodiments, it also includes: a second resistor 330, and the second end of the first part 311 is grounded through the second resistor 330. The second resistor 330 can be set on the second side of the dielectric board, or on the first side of the dielectric board, and the specific position is selected according to the routing or design requirements of the dielectric board. In order to be effectively grounded, the second resistor 330 can be connected to the second network ground plane set on the first side of the dielectric board through a via. The input port 340 of the second power division network group can be connected to the output port of the first power division network group through a via.

[0078] Please refer to Figure 4 , which shows an example structural diagram of a coaxial cable installation in a calibration network component provided in some embodiments of the present application. Figure 4 As shown, it includes: a first coaxial cable 410 and a second coaxial cable 420 ; the first coaxial cable 410 is connected to the input end of the second part 430 ; the second coaxial cable 420 is connected to the output end of the second part 430 .

[0079] The coaxial cables at the input and output ends of the second part of the directional coupler can achieve coplanar visual welding between the inner and outer conductors, see reference Figure 4 In the figure, the outer conductor 440 shows the outer conductor welding position and features, and the inner conductor 450 shows the inner conductor welding position and features. At the same time, the inner conductor pad uses a convex step feature to ensure impedance consistency in a wide frequency band. However, this part of the traditional calibration network component cannot be welded on the same side. For example, it is set on the upper and lower layers of the dielectric plate, and coplanar visible welding cannot be achieved, which increases the difficulty of welding and the complexity of equipment maintenance.

[0080] Please refer to Figure 5 , which shows an example structure diagram of a pad in a calibration network component provided in some embodiments of the present application. Figure 5 As shown, the calibration network component also includes: a pad 520, on which the dielectric plate 510 is mounted, and two longitudinal edges of the pad 520 are folded toward the first surface of the dielectric plate 510 to form a first flange 521 and a second flange 522 for supporting the dielectric plate 510.

[0081] Among them, the material of the pad 520 can be metal or plastic, and the weight and flatness support of each component on the dielectric plate can be achieved through the pads 520 of different materials. The first side of the dielectric plate 510 can be the back side of the calibration network component, and the second side of the dielectric plate 510 can be the front side of the calibration network component. The downward bending of the pad 520 can effectively improve the flatness of the dielectric plate support of the calibration network component, and prevent interference with the first power division network group set on the first side when routing on the second side of the dielectric plate, thereby affecting the phase consistency of the entire machine.

[0082] In some embodiments, the two longitudinal edges of the pad 520 can be folded toward the second surface of the dielectric plate 510 to form a third flange and a fourth flange, respectively, for supporting the dielectric plate 510. In this structure, when the coaxial cable is connected to the directional coupler, when the length of the coaxial cable after welding is greater than the width formed by the third flange and the fourth flange, through holes can be set on the third flange and the fourth flange to allow the coaxial cable to pass through.

[0083] Based on the calibration network components in the above embodiments, a calibration network component of a three-level power division network is provided and described with reference to the accompanying drawings.

The first power division network B and the first power division network C respectively have two output ports, which can be connected to the input port of the second power division network group on the second surface of the dielectric board through a plurality of vias 631, and the number of vias 631 is determined based on the number of output ports of the first power division network B and the first power division network C. For example, in this embodiment, the number of output ports of the first power division network B and the first power division network C is 4 in total, and the number of vias is also 4. A second network floor 640 is also arranged on the first surface of the dielectric board, and is connected to the first network floor on the second surface through a plurality of vias through the dielectric board. In the layout of the first surface of the dielectric board, the first power division network group can be arranged in the upper half of the first surface, and the second network floor 640 can be arranged in the lower half of the first surface.
