DETAILED DESCRIPTION

[0052] The embodiments of the present application solve the technical problem that the structure of the power distributor in the prior art is relatively complex by providing a power distributor, a distribution method, an assembly method and a distribution device.

[0053] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0054] The embodiment of the present application provides a power divider, comprising: a fixed plate, a movable plate rotatably connected to the fixed plate, an input end and at least two output ends; the fixed plate comprises a first microstrip line and a first connecting portion; the movable plate comprises a second microstrip line and a second connecting portion connected to the second microstrip line; the second connecting portion is rotatably connected to the first connecting portion; the first microstrip line is a first arc formed with the first connecting portion as an axis; the second microstrip line is a second arc formed with the second connecting portion as an axis; the first microstrip line and the second microstrip line have a projected overlapping area in a preset radial direction; the input end is connected to the first connecting portion or the second connecting portion; at least one output end is connected to the first microstrip line, and at least one output end is connected to the second microstrip line. It can be seen that by rotating the second connecting portion, the length of the projected overlapping area of ​​the first microstrip line and the second microstrip line in the preset radial direction is changed, thereby changing the power distribution ratio of the output end of the power divider, while accurately controlling the power distribution ratio, making the change of the power distribution ratio more flexible, the structure is simple and compact, the manufacturing cost is low, and the adaptability in various application scenarios is enhanced.

[0055] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0056] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0057] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those shown or described.

[0058] It should be understood that the orientations or positional relationships indicated by terms such as “center”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0059] It should be noted that, unless otherwise clearly specified and limited, the terms "connected", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] As a key communication electronic device, the power divider plays a vital role in RF and microwave equipment. It is mainly used to divide an input signal into two or more output signals according to a specific ratio. The power divider with arbitrary power distribution ratio function is widely used because it can flexibly adjust the power ratio of each output port and dynamically adjust the signal transmission efficiency between different circuits without changing the physical connection. For example: in phased array radar systems, it is used to adjust the excitation amplitude of each unit antenna to form different beam patterns; in multiple-input multiple-output systems, it optimizes the signal transmission path, improves the link quality and reduces the bit error rate; realizes the effective management and distribution of signals between base stations and mobile devices; and adjusts the output power and coverage between transmitters and antennas.

[0061] Existing power dividers mainly achieve the change of power distribution ratio in two ways: one is to use microwave switches combined with traditional power dividers; the other is to use reconfigurable impedance transformers as core components. The former changes the output ratio by switching different paths, while the latter relies on adjusting component parameters to achieve the same purpose.

[0062] However, both methods have certain limitations. The method based on microwave switches and traditional power dividers is relatively complex in structure, requires multiple functional devices to work together, and introduces additional losses. In addition, switching elements such as PIN diodes, gallium arsenide field-effect transistors (GaAs FETs), etc., will bring parasitic capacitance, resistance and other non-ideal factors, affecting the overall performance of the system, such as increasing insertion loss and reducing isolation, while also increasing manufacturing difficulty and cost. Although the use of reconfigurable impedance converters can solve the above problems to a certain extent, its core components usually include varactor diodes or switches, which will also introduce parasitic effects, and in order to control these core components, it is necessary to integrate additional control circuits or even microcontrollers or digital signal processors, further increasing the complexity and cost of the design.

[0063] In order to solve the above problems, the embodiments of the present application provide a power divider, a power distribution method matching the power divider, and a power divider assembly method.

[0064] First, the embodiment of the present application first describes the power divider. Figure 1 As shown, it is a structural schematic diagram of a power distributor provided in an embodiment of the present application, which is mainly composed of a fixed plate 1, a movable plate 2 rotatably connected to the fixed plate 1, an input terminal P1, a first output terminal P2 and a second output terminal P3.

[0065] It should be noted that the number of input terminals and output terminals of the power divider provided in the embodiment of the present application can be set according to actual conditions. In the subsequent embodiments of the present application, one input terminal and two output terminals are continued to be used as examples to introduce the power divider provided by the present application. The number of input terminals and output terminals is only described here according to a specific embodiment and cannot be used as a limitation to the scheme of the present application.

[0066] like Figure 1 , Figure 2a , Figure 2b , Figure 3a and Figure 3b As shown, the fixed plate 1 includes a first microstrip line 11 and a first connecting portion 12 , and the movable plate 2 includes a second microstrip line 21 and a second connecting portion 22 .

[0067] The first connection portion 12 is rotatably connected to the second connection portion 22, the first microstrip line 11 is a first arc formed with the first connection portion 12 as an axis, the second microstrip line 21 is a second arc formed with the second connection portion 22 as an axis, and the first microstrip line 11 and the second microstrip line 21 have a projected overlapping area in a preset radial direction. For example, Figure 2b As shown, the effective area A surrounded by the thicker dotted lines on the first microstrip line 11 and the second microstrip line 21 refers to the projection overlap area in the preset radial direction, where the preset radial direction refers to the second connecting portion 22 as the axial direction. Figure 2b In the direction corresponding to the upper left area in , the length of the effective area A is Lc.

[0068] It should be noted that the radial direction refers to a straight line path from a central point and extending outward or inward in the radial direction. In the embodiment of the present application, the preset radial direction may refer to a direction from the position where the first connecting portion 12 and the second connecting portion 22 are connected together, pointing to any point on the first arc or the second arc, or pointing to any point on a sphere formed by any of the first arc and the second arc.

[0069] When the second connection portion 22 rotates based on the first connection portion 12, the length of the projected overlapping area of ​​the first microstrip line 11 and the second microstrip line 21 in the preset radial direction is changed, that is, the length Lc of the effective area A is changed. In addition, the output ratio of the output signals of the output ends corresponding to the first microstrip line 11 and the second microstrip line 21 is changed, that is, the power distribution ratio of the power divider is changed.

[0070] In order to make the rotation process between the second connection part 22 and the first connection part 12 smoother, the geometric structure of the first connection part 12 and the second connection part 22 can be set to a sleeve-connected circular ring shape.

[0071] The first arc and the second arc have the same axis. The distance from each point on the first arc to the axis is equal. The distance from each point on the second arc to the axis is equal. The axis is the position where the first connecting portion 12 and the second connecting portion 22 are connected together.

[0072] like Figure 2b , Figure 3b and Figure 3c As shown, the radius R2 of the second arc can be smaller than the radius R1 of the first arc, that is, the arc length of the second arc is smaller than the arc length of the first arc. In some embodiments, the radius R2 of the second arc can also be larger than the radius R1 of the first arc, that is, the second microstrip line 21 of the movable plate 2 is located outside the first microstrip line 11 of the fixed plate 1.

[0073] Since the geometric dimensions of the microstrip line will affect the characteristic impedance of the microstrip line, and thus affect the reflection and transmission efficiency of the signal. In some embodiments, in order to change the power distribution ratio corresponding to the power divider, the line width W1 and thickness of the first microstrip line 11 can be changed, and the line width W2 and thickness of the second microstrip line 21 can be changed. The embodiment of the present application is only described by taking the example that the line width W1 of the first microstrip line 11 is equal to the line width W2 of the second microstrip line 21, and the thickness of the first microstrip line 11 is equal to the thickness of the second microstrip line 21.

[0074] The coupling effect generated by the effective area A will also affect the characteristic impedance of the first microstrip line 11 and the second microstrip line 21. Therefore, for any power divider provided in the present application, Figure 2a and Figure 2b As shown, by changing the length Lc of the effective area A or changing the spacing S between the first microstrip line 11 and the second microstrip line 21, the power distribution ratio of the output signal at the corresponding output end of the power divider is changed.

[0075] In order to achieve better input echo, reduce the possibility of the input signal input at the input end being reflected back, and transmit most of the input signal to the corresponding output end for output, the ratio between the first length of the first microstrip line 11 in the projection overlapping area and the second length not in the projection overlapping area is greater than the preset first ratio; the ratio between the third length of the second microstrip line 21 in the projection overlapping area and the fourth length not in the projection overlapping area is greater than the preset second ratio.

[0076] The preset first ratio and the preset second ratio may be equal or unequal, and are mainly set according to the characteristic impedance corresponding to the first microstrip line 11 and the second microstrip line 21 and the interval of the power distribution ratio corresponding to the power divider.

[0077] Exemplarily, the ratio of the L1 arc segment within the effective area A on the first microstrip line 11 to the L2 arc segment outside the effective area A is greater than 2, and the ratio of the L3 arc segment within the effective area A to the L4 arc segment outside the effective area A on the second microstrip line 21 is greater than 2.

[0078] like Figure 3a and Figure 3b As shown, the fixing plate 1 further includes a first feed line 141, a second feed line 142, a third feed line 143, a fixing plate dielectric substrate 13 and a grounding metal sheet.

[0079] The first feeder line 141 , the second feeder line 142 and the third feeder line 143 are all used to transmit signals and reduce signal loss and reflection during the transmission process.

[0080] The grounding metal sheet is used to provide a reference potential for the first microstrip line 11 and the second microstrip line 21, which helps to form a closed electromagnetic field environment and reduce external interference. At the same time, the grounding metal sheet can affect the characteristic impedance and signal propagation mode of the first microstrip line 11 and the second microstrip line 21.

[0081] The fixed plate dielectric substrate 13 is generally made of insulating material and is used to separate the grounded metal sheet from the first microstrip line 11 and the second microstrip line 21. The height (thickness) of the fixed plate dielectric substrate 13 affects the characteristic impedance of the first microstrip line 11 and the second microstrip line 21. When the height of the fixed plate dielectric substrate 13 is increased (the thickness is increased), the distance between the first microstrip line 11 and the second microstrip line 21 and the grounded metal sheet becomes farther, which usually increases the characteristic impedance; otherwise, the characteristic impedance is reduced.

[0082] The first end of the first feeder 141 is connected to the first connection portion 12 or the second connection portion 22, and the second end of the first feeder 141 serves as an input end; the second end of the second feeder 142 abuts against the outer side of the second microstrip line 21, and the first end of the second feeder 142 serves as at least one output end; the first end of the third feeder 143 is connected to the second end of the first microstrip line 11, and the second end of the third feeder 143 serves as at least one other output end.

[0083] For example, Figure 3a and Figure 3b As shown, the first microstrip line 11 , the first feed line 141 , the second feed line 142 , the third feed line 143 and the first connecting portion 12 are all arranged on the first surface of the fixed plate dielectric substrate 13 , and the grounding metal sheet covers the second surface of the fixed plate dielectric substrate 13 .

[0084] Among them, the first end of the first feeder 141 is connected to the first connecting portion 12, and the second end of the first feeder 141 serves as the input terminal P1; the second end of the second feeder 142 is located in the extension space of the first end of the first microstrip line 11, and abuts against the outer side of the second microstrip line 21 to receive the signal transmitted through the second microstrip line 21, and the first end of the second feeder 142 serves as the first output terminal P2; the first end of the third feeder 143 is connected to the second end of the first microstrip line 11 to receive the signal transmitted through the first microstrip line 11, and the second end of the third feeder 143 serves as the second output terminal P3.

[0085] like Figure 3c As shown, the movable plate 2 further includes a movable plate dielectric substrate 23, and the second connecting portion 22 further includes a rotating member and a connecting line. The connecting line connects the first end of the second microstrip line 21 with the rotating member, and the rotating member is rotatably connected to the first connecting portion 12, so that the signal can be transmitted in the first connecting portion 12 and the rotating member, and then transmitted to the first output end P2 corresponding to the second microstrip line 21 for output.

[0086] The second microstrip line 21, the rotating member and the connecting member are all arranged on the movable plate dielectric substrate 23, and the movable plate dielectric substrate 23 covers the fixed plate dielectric substrate 13. When the rotating member rotates based on the first connecting portion 12, the second microstrip line 21 is driven to rotate around the rotating member, so that the length Lc of the effective area A changes, thereby changing the influence of the coupling effect on the characteristic impedance.

[0087] The function of the movable plate dielectric substrate 23 can refer to the above description of the function of the fixed plate dielectric substrate 13, which will not be repeated here.

[0088] In summary, an embodiment of the present application provides a power divider, comprising: a fixed plate 1, a movable plate 2 rotatably connected to the fixed plate 1, an input end and at least two output ends; the fixed plate 1 comprises a first microstrip line 11 and a first connecting portion 12; the movable plate 2 comprises a second microstrip line 21 and a second connecting portion 22 connected to the second microstrip line 21; the second connecting portion 22 is rotatably connected to the first connecting portion 12; the first microstrip line 11 is a first arc formed with the first connecting portion 12 as an axis; the second microstrip line 21 is a second arc formed with the second connecting portion 22 as an axis; the first microstrip line 11 and the second microstrip line 21 have a projected overlapping area in a preset radial direction; the input end is connected to the first connecting portion 12 or the second connecting portion 22; at least one output end is connected to the first microstrip line 11, and at least one other output end is connected to the second microstrip line 21. It can be seen that by rotating the second connecting part 22 to change the length of the projected overlapping area of ​​the first microstrip line 11 and the second microstrip line 21 in the preset radial direction, the power distribution ratio at the output end of the power divider is changed. While accurately controlling the power distribution ratio, the change of the power distribution ratio is made more flexible, the structure is simple and compact, the manufacturing cost is low, and the adaptability in various application scenarios is enhanced.

[0089] Based on the same inventive concept, the embodiment of the present application provides a power distribution method, which matches the power distributor provided above. Figure 4 As shown, a power allocation method provided by the present application includes steps S41 and S42.

[0090] Step S41, determining a target rotation angle of the movable plate 2 according to a target power distribution ratio corresponding to the signal to be distributed;

[0091] Step S42, control the second connection part 22 to rotate and maintain the target rotation angle based on the first connection part 12, so that the signal to be distributed input from the input end is transmitted to the corresponding at least two output ends through the first microstrip line 11 and the second microstrip line 21, and at least two output signals that meet the target power distribution ratio are obtained.

[0092] Regarding step S41, the target rotation angle of the movable plate 2 is determined according to the target power distribution ratio corresponding to the signal to be distributed.

[0093] It should be noted that the signal to be distributed refers to the input signal received by the input end. The target power distribution ratio refers to the power distribution ratio that the power divider needs to provide under the current working state.

[0094] Regarding step S42, the second connection part 22 is controlled to rotate and maintain the target rotation angle based on the first connection part 12, so that the signal to be distributed input from the input end is transmitted to the corresponding at least two output ends through the first microstrip line 11 and the second microstrip line 21, and at least two output signals that meet the target power distribution ratio are obtained.

[0095] The second connection part 22 rotates and maintains the target rotation angle based on the first connection part 12, so that the length Lc of the effective area A on the first microstrip line 11 and the second microstrip line 21 is maintained at a length matching the target power distribution ratio, thereby changing the influence of the coupling effect on the characteristic impedance to change the power distribution ratio of the power divider in the current working state.

[0096] For example, Figure 5a , Figure 5b and Figure 5c When the target rotation angle θ is equal to 20°, 55° and 70° respectively, when the second connection part 22 rotates the corresponding target rotation angle based on the first connection part 12 and maintains it, the corresponding positional relationship between the movable plate 2 and the fixed plate 1 shows that the length Lc of the effective area A on the first microstrip line 11 and the second microstrip line 21 is maintained at a length matching the target power allocation ratio and also changes accordingly.

[0097] Figure 6 This is a schematic diagram of the functional relationship between the scattering parameters and the frequency before and after the target rotation angle changes. Figure 6 In the figure, (a) is the functional relationship between the scattering parameter and the frequency when the target rotates at an angle of 30°, and (b) is the functional relationship between the scattering parameter and the frequency when the target rotates at an angle of 45°. By comparing (a) and (b), the changes in signal transmission and reflection characteristics are clearly shown.

[0098] Among them, curve S11 represents the reflection coefficient of the input end, that is, when the signal to be allocated is input from the input end P1, the ratio of the power reflected back from the input end P1 to the incident power of the signal to be allocated. Curve S21 represents the transmission coefficient from the input end P1 to the first output end P2, that is, when the signal to be allocated is input from the input end P1, the ratio of the first output power output from the first output end P2 to the incident power of the signal to be allocated. Curve S31 represents the transmission coefficient from the input end P1 to the second output end P3, that is, when the signal to be allocated is input from the input end P1, the ratio of the second output power output from the second output end P3 to the incident power of the signal to be allocated.

[0099] It can be seen that as the target rotation angle changes, the transmission and reflection characteristics of the signal transmitted to the corresponding output end can be changed, thereby accurately and flexibly controlling the power distribution ratio of the power divider.

[0100] In summary, the embodiment of the present application provides a power distribution method, which matches the power divider provided above, determines the target rotation angle of the movable plate 2 according to the target power distribution ratio corresponding to the signal to be distributed; controls the second connection part 22 to rotate and maintain the target rotation angle based on the first connection part 12, so that the signal to be distributed input from the input end is transmitted to the corresponding at least two output ends through the first microstrip line 11 and the second microstrip line 21, and obtains at least two output signals that meet the target power distribution ratio. It can be seen that by rotating the second connection part 22 to change the influence of the coupling effect of the first microstrip line 11 and the second microstrip line 12 on the characteristic impedance, and then changes the power distribution ratio at the output end of the power divider, while accurately controlling the power distribution ratio, making the change of the power distribution ratio more flexible, the structure is simple and compact, the manufacturing cost is low, and the adaptability in various application scenarios is enhanced.

[0101] Based on the same inventive concept, the embodiment of the present application provides a method for assembling a target power divider, wherein the target power divider matches the power divider provided above. Figure 7 As shown, a target power device assembly method provided by the present application includes steps S71 to S73.

[0102] Step S71, determining the target design variables of the power divider to be assembled according to the interval of the power distribution ratio corresponding to the preset transmission signal;

[0103] Step S72, determining a target movable plate that meets the target design variables from at least one movable plate to be selected; determining a target fixed plate that meets the target design variables from at least one fixed plate to be selected;

[0104] Step S73, rotatably connecting the second connection portion 22 of the target movable plate to the first connection portion 12 of the target fixed plate, so as to assemble the target movable plate and the target fixed plate into a target power distributor.

[0105] Regarding step S71, the target design variables of the power divider to be assembled are determined according to the interval of the power distribution ratio corresponding to the preset transmission signal.

[0107] Exemplarily, when the power allocation ratio corresponding to the preset transmission signal is in the interval of 2.51 to 1.38 and the corresponding frequency variation range is 0.97 GHz to 1.58 GHz, the target design variables can be determined as the radius of the first arc is 11.5 mm, the radius of the second arc is 10 mm, the line widths of the first microstrip line 11 and the second microstrip line 21 are both 0.8 mm, and the spacing between the first microstrip line 11 and the second microstrip line 21 is 0.04 mm.

[0108] Regarding step S72, a target movable plate that meets the target design variables is determined among at least one movable plate to be selected; and a target fixed plate that meets the target design variables is determined among at least one fixed plate to be selected.

[0109] It can be understood that, in the case where there is only one movable plate to be selected and multiple fixed plates to be selected, the one movable plate to be selected is determined as the target movable plate, and the target fixed plate that meets the target design variables is determined from the multiple fixed plates to be selected. In the case where there is only one fixed plate to be selected and multiple movable plates to be selected, the one fixed plate to be selected is determined as the target fixed plate, and the target movable plate that meets the target design variables is determined from the multiple movable plates to be selected.
