Description

[Technical field]

[0001] The present application relates to the field of wireless communications, and in particular to a feed stripline, a phase shifter in which the feed stripline is disposed, an array antenna, and a base station. [Background technology]

[0002] The powered stripline is a common component in communication base stations, and can function as radio frequency functional devices such as power dividers, couplers, filters, and electronic tilts to realize the transmission of wireless microwave signals. Most existing powered striplines are planar structures. To ensure electrical performance, the power divider branches in the powered stripline extend along different transmission paths in a plane, avoiding signal series connection caused by crossing or overlapping. As a result, it is difficult to control the planar area of ​​the powered stripline, and part of the planar area may not be utilized. As a result, the area ratio of the powered stripline is large, which is not in line with the miniaturization trend of current communication devices such as base stations. Summary of the Invention

[0003] The present invention provides a three-dimensional feed stripline structure, a phase shifter including the three-dimensional feed stripline structure, an array antenna, and a base station, in order to reduce the area ratio of the feed stripline. The present application specifically includes the following technical solutions:

[0004] According to a first aspect, the present application provides a powered stripline, the powered stripline including a signal input line, a first power branch line, and a second power branch line, one end of the signal input line is conducted to an external signal source, and the other end is electrically connected to each of the first power branch line and the second power branch line, the first power branch line includes a jump structure, the first power branch line spans from one side of the second power branch line to the other side of the second power branch line by using the jump structure, and the jump structure and the second power branch line are spaced apart from each other.

[0005] In the power feed strip line in the present application, the first power branch line and the second power branch line are separately connected to the signal input line, so that an external electric signal input from the signal input line can be separately transmitted to the first power branch line and the second power branch line, and the electric signal is separately transmitted on the extension path of the first power branch line and on the extension path of the second power branch line. By setting the extension lengths of the first power branch line and the second power branch line to be different from each other, a phase difference can be generated between the electric signal output by the first power branch line and the electric signal output by the second power branch line, and a preset tilt can be obtained accordingly.

[0006] In the present application, in the feeding stripline, a jump structure is further disposed on the first power branch line, so that the first power branch line can extend a certain distance on one side of the second power branch line and also span to the other side of the second power branch line using the jump structure for further extension. The jump structure and the second power branch line are spaced apart from each other. Specifically, when the first power branch line spans from one side to the other side of the second power branch line, the first power branch line does not overlap with the second power branch line. This ensures the normal transmission of electrical signals in each of the first power branch line and the second power branch line. In addition, the jump structure extends the extension range of the first power branch line, improves the utilization rate of the spatial area of ​​the feeding stripline, reduces the overall volume of the feeding stripline, and ensures the electrical function of the feeding stripline.

[0007] In a possible implementation, the signal input line and the second power branch line are both located in a first plane, the first power branch line includes a first segment and a second segment located in the first plane, the first segment and the second segment are distributed on two opposing sides of the second power branch line, and the jump structure includes a connection segment located in the second plane, the connection segment being electrically connected to each of the first segment and the second segment.

[0008] In this implementation, the first power branch line is divided into a first segment and a second segment independent of each other, and the first segment and the second segment are distributed on two opposite sides of the second power branch line, so that the main structures of the first power branch line, the signal input line, and the second power branch line are all located in a first plane. This defines the planar structure of the body of the powered strip line in this application, and facilitates the synchronous manufacturing of the first segment, the second segment, the signal input line, and the second power branch line. The connecting segment located in the second plane cooperates with the first segment and the second segment separately to implement the electrical signal transmission between the first segment and the second segment. This can ensure the electrical signal transmission in the first power branch line under the condition that the jump structure and the second power branch line are spaced apart from each other.

[0009] In a possible implementation, the jump structure further includes a first pin and a second pin, the first pin and the second pin being distributed on two opposing ends of the connection segment, the connection segment being in contact with and conductive to the first segment via the first pin, and the connection segment being further in contact with and conductive to the second segment via the second pin.

[0010] In this implementation, the jump structure further includes a first pin and a second pin distributed at two opposite ends of the connection segment, the first pin and the second pin being connected between the first plane and the second plane, respectively, so that the two opposite ends of the connection segment are in contact with and conductive with the first segment and the second segment, respectively. An electrical signal transmitted within the first segment is transmitted sequentially through the first pin, the connection segment, and the second pin, and finally to the second segment, and continues to be transmitted through the second segment to an endpoint of the first power branch.

[0011] In a possible implementation, the first pin, the second pin, and the connecting segment are of one unitary construction.

[0012] In this implementation, the jump structure is integrally formed, and the connection between the connection segment and the first and second pins is more stable, thereby improving the reliability of the first power branch line.

[0013] In a possible implementation, the first pin and the first segment are welded together and the second pin and the second segment are also welded together.

[0014] In this implementation, the welding and fastening can ensure reliable contact and continuity between the first pin and the first segment, and can ensure reliable contact and continuity between the second pin and the second segment.

[0015] In a possible implementation, the first segment includes a first end remote from the signal input line, the second segment includes a second end close to the first segment, a first opening and a second opening are disposed at the first end and the second end, respectively, a first pin extends into the first opening and is in contact with and conductive to the first segment, and a second pin extends into the second opening and is in contact with and conductive to the second segment.

[0016] In this implementation, the first opening is located in the first segment near the second segment such that the first pin extends into the first opening, and the second opening is located in the second segment near the first segment such that the second pin also extends into the second opening, thereby ensuring reliable contact between the first pin and the first segment and ensuring reliable contact between the second pin and the second segment.

[0017] In a possible implementation, the jump structure is elastic, and when the jump structure extends into the first opening and the second opening separately, an elastic deformation is formed between the first pin and the second pin, and an elastic force exists that draws them toward or away from each other.

[0018] In this implementation, in addition to welding and electrical continuity, elastic deformation can ensure reliable overlapping contact between the first pin and the first opening. In addition to welding and electrical continuity, elastic deformation can ensure reliable overlapping contact between the second pin and the second opening. In addition, there is an elastic force between the first pin and the second pin that attracts or pulls away from each other, and the elastic force of the first pin and the elastic force of the second pin interact with each other to ensure reliable overlapping contact between the first pin and the second pin and the first opening and the second opening.

[0019] In a possible implementation, the connection segment includes opposing first and second coupling ends, a protrusion of the first coupling end in the first plane at least partially overlapping the first segment, and the first coupling end is electrically connected to the first segment through the coupling; The protrusion of the second coupling end in the first plane at least partially overlaps the second segment, and the second coupling end is also electrically connected to the second segment through the coupling.

[0020] In this implementation, the connecting segment is not in contact with the first segment and the second segment, but separately forms an interconnection structure with the first segment and the second segment through the first coupling end and the second coupling end, and the electrical signal transmitted in the first segment is transmitted to the jump structure through the coupling and then transmitted to the second segment, also through the coupling, so that the jump structure transmits the electrical signal in the first segment to the second segment.

[0021] In one implementation, a first coupling capacitor is formed between the first coupling end and the first segment, and a second coupling capacitor is formed between the second coupling end and the second segment.

[0022] In this implementation, the capacitor structure is separately formed between the jump structure and the first segment and the second segment, and the coupling electrical connection is implemented in the form of a first coupling capacitor and a second coupling capacitor.

[0023] In a possible implementation, an insulated isolation pad is filled separately between the first coupling end and the first segment and between the second coupling end and the second segment.

[0024] In this implementation, the isolation pad can be formed by injection molding or the like to form a fixation between the first coupling end and the first segment and a fixation between the second coupling end and the second segment. The isolation pad can ensure a relative position between the jump structure and the first segment and the second segment to ensure electrical stability of the first coupling capacitor and the second coupling capacitor.

[0025] In a possible implementation, the power feed stripline includes a printed circuit board, the printed circuit board including a first metal surface and a second metal surface arranged oppositely, the first metal surface configured as a first plane and the second metal surface configured as a second plane.

[0026] In this implementation, the power feed stripline is prepared on a printed circuit board (PCB) to form a form of a stripline. The PCB has a first metal surface and a second metal surface arranged oppositely. The first metal surface is configured as a first plane of the power feed stripline. The signal input line, the first segment, the second segment, and the second power branch line may be arranged on the first metal surface, and the connecting segment of the jump structure may be arranged on the second metal surface. In this case, the second metal surface is configured as a second plane, and the PCB substrate may form a reliable support for the power feed stripline.

[0027] In a possible implementation, the printed circuit board includes a via, the via is connected between the first plane and the second plane, and the first pin and the second pin are both configured as conductive elements that pass through the via.

[0028] In this implementation, the vias can be manufactured on the printed circuit board by using existing process technology. The vias are connected between the first plane and the second plane. In addition, the positions of the vias are arranged so that the vias can be located between the connection segment and the first segment and between the connection segment and the second segment. And the first pin and the second pin are respectively connected between the connection segment and the first segment and arranged to connect between the connection segment and the second segment through the vias, so that the jump structure can reliably overlap with each of the first segment and the second segment.

[0029] In a possible implementation, the first pin and the second pin are each configured as a conductive material filled in a via; or The first and second pins pass separately through the vias and are fixedly connected to the first and second segments, respectively.

[0030] In this implementation, the via is filled with metal or another conductive material to form a conductive via. This realizes the function of the first pin and the second pin, and ensures that the connection segment overlaps the first segment and the second segment, respectively. Alternatively, the first pin and the second pin may be configured as a conductive element, respectively. After passing through the via, the conductive element overlaps the connection segment and the first segment, and is connected between the connection segment and the second segment, thereby realizing the electrical signal transmission function of the jump structure between the first segment and the second segment.

[0031] In a possible implementation, the input matching line, the first power matching line, and the second power matching line are further disposed on a second metal plane; the input matching line extends parallel to the signal input line, the first power matching line extends parallel to the first power branch line, and the connection segment is configured as part of the first power matching line; The second power matching line includes a third segment and a fourth segment, the third segment being located on one side of the connection segment and extending parallel to the second power branch line, and the fourth segment being located on the other side of the connection segment and also extending parallel to the second power branch line.

[0032] In this implementation, an input matching line for the signal input line is further arranged on a second outer surface arranged opposite to the first outer surface, and the input matching line and the signal input line cooperate to transmit an electrical signal transmitted from a signal source. In addition, a first power matching line and a second power matching line are also arranged for the first power branch line and the second power branch line, respectively. The first power branch line and the first power matching line cooperate to transmit an electrical signal in the extension direction of the first power branch line, and the second power branch line and the second power matching line cooperate to transmit an electrical signal in the extension direction of the second power branch line. The feature of separation between the first outer surface and the second outer surface on the PCB fixes the positions of the lines on these two outer surfaces relatively, providing a basis for implementing signal conduction by cooperation.

[0033] When the first power matching line is disposed on the second outer surface, it may be understood that the connection segment may be configured as part of the first power matching line and configured to perform transmission of electrical signals between the first segment and the second segment and transmission of electrical signals in the first power matching line.

[0034] In a possible implementation, vias on the printed circuit board may alternatively be located between the signal input line and the input matching line, and / or between the first power branch line and the first power matching line, and / or between the second power branch line and the second power matching line, configured to form an electrical path between each line and its corresponding matching line and to adjust the equivalent dielectric constant.

[0035] In a possible implementation, the included angle α between the protrusion of the connection segment in the first plane and the second power branch satisfies the condition 45°≦α≦90°.

[0036] In this implementation, the connection segment spans the second power branch line and is spaced apart from the second power branch line, i.e., the connection segment and the second power branch line form a spatial intersection, so that the protrusion of the connection segment in the first plane partially overlaps with the second power branch line. An included angle between the connection segment and the second power branch line is set, so that the overlapping area between the connection segment and the second power branch line can be controlled, thereby avoiding electrical signal interference caused by an excessive overlapping area between the connection segment and the second power branch line.

[0037] In a possible implementation, the first plane is parallel to the second plane.

[0038] In this implementation, the first plane is the plane in which the second power branch is located, and the second plane is the plane in which the connection segment is located. Since the first plane is set to be parallel to the second plane, in the process of crossing the second power branch, the connection segment always maintains a stable height difference with the second power branch. This helps to control signal interference between the connection segment and the second power branch.

[0039] In a possible implementation, the powered stripline further includes a signal input port, a first output port, and a second output port, where one end of the signal input line remote from the first power branch line and the second power branch line is connected to the signal input port, one end of the first power branch line remote from the signal input line is connected to the first output port, and one end of the second power branch line remote from the signal input line is connected to the second output port.

[0040] In this implementation, the signal input line is connected to the signal input port to receive a signal source, and the first power branch line and the second power branch line separately output signals to the endpoints via the signal output ports respectively connected to the first power branch line and the second power branch line to realize the phase allocation function of the powered stripline.

[0041] In a possible implementation, the powered stripline further includes a shielded cavity, and the input line, the first power branch line, and the second power branch line are all contained and secured within the shielded cavity and are insulated from the shielded cavity.

[0042] In this implementation, the feeding stripline is configured as a suspended stripline, and the shielding cavity can shield external signal interference to reduce loss of the electrical signal transmitted by the feeding stripline within the shielding cavity in this application.

[0043] According to a second aspect, the present application provides a phase shifter. The phase shifter includes a sliding medium and the power strip line provided in the first aspect of the present application. The sliding medium overlaps the first power branch line and / or the second power branch line separately, and the sliding medium slides relative to the first power branch line and / or the second power branch line to adjust the phase of the signal output by the phase shifter.

[0044] According to a second aspect of the present application, a feed stripline is used as a power divider in a phase shifter, and a sliding medium can change the electrical lengths of the first power branch line and the second power branch line by sliding relative to the feed stripline to adjust a phase difference between an electrical signal transmitted in the first power branch line and an electrical signal transmitted in the second power branch line.

[0045] According to a third aspect, the present application provides an array antenna, the array antenna including the feed stripline provided in the first aspect of the present application and / or the phase shifter provided in the second aspect of the present application.

[0046] According to a fourth aspect, the present application further provides a base station, the base station including the feed stripline provided in the first aspect of the present application, and / or the phase shifter provided in the second aspect of the present application, and / or the array antenna provided in the third aspect of the present application.

[0047] In a possible implementation, the base station further includes a building baseband processing unit, a remote radio unit, and an antenna feeding system. The feeding strip line provided in the first aspect of the present application, and / or the phase shifter provided in the second aspect of the present application, and / or the array antenna provided in the third aspect of the present application are disposed in the antenna feeding system. The remote radio unit is connected between the building baseband processing unit and the antenna feeding system. The antenna feeding system is connected to the building baseband processing unit through the remote radio unit to realize a transceiver function of a wireless signal.

[0048] In the phase shifter, array antenna, and base station provided in the second to fourth aspects of the present application, since the feeding stripline in the present application is used, it can be seen that, similar to the feeding stripline in the first aspect of the present application, the first power branch line can be distributed on two sides of the second power branch line, improving the planar utilization rate of the feeding stripline, making the volume ratio of the feeding stripline smaller, and facilitating the overall volume control of the product in various aspects.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0050] The following describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. It is clear that the described embodiments are only a part, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0051] The base station in this application includes a building baseband processing unit (BBU), a remote radio unit (RRU), and an antenna feeding system 500, as shown in Fig. 1. The remote radio unit is connected between the building baseband processing unit and the antenna feeding system 500. There may be multiple antenna feeding systems 500, and there may be multiple remote radio units as many as the antenna feeding systems 500. Each antenna feeding system 500 cooperates with one remote radio unit, and each of the multiple antenna feeding systems 500 is connected to one building baseband processing unit through a corresponding remote radio unit to realize the function of transmitting and receiving radio signals.

[0052] Please refer to the schematic diagram of the structure of the antenna feeding system 500 shown in Figure 1. The antenna feeding system 500 includes an array antenna 400, a pole 502, an antenna support 503, a connector seal element 504, and a grounding device 501. The pole 502 is fixed relative to the ground. The antenna support 503 is connected between the array antenna 400 and the pole 502, and realizes the fixed connection between the array antenna 400 and the pole 502. In some embodiments, the antenna support 503 can be further arranged as an adjustable support, adjusting the orientation and angle of the array antenna 400 relative to the pole 502, cooperating with the signal transmission angle of the array antenna 400, and ensuring that there is a preset tilt formed between the signal transmitted by the antenna feeding system 500 and the ground. The base station in this application can be arranged in any public place or cell, and realizes the signal coverage function in the area corresponding to the base station.

[0053] The array antenna 400 is the array antenna in this application. The array antenna 400 is further electrically connected to a grounding device 501 to realize the grounding function of the array antenna 400. One end of the grounding device 501 remote from the array antenna 400 may be further connected and fixed to a pole 502 to realize the grounding function through the pole 502. Alternatively, it may be understood that the grounding device 501 may be directly fixed to the ground to ensure the reliable grounding function of the array antenna 400. The array antenna 400 is usually housed in a sealed box (radome). In terms of mechanical performance, the box needs to have sufficient rigidity and strength, as well as the ability of anti-dirt and waterproof, etc., to protect the internal components of the array antenna 400 from the external environment. In terms of electrical performance, the box needs to have good electromagnetic wave transmission characteristics to ensure the signal transmission and reception function of the array antenna 400. A connector seal element 504 may be further disposed between the grounding device 501 and the box of the array antenna 400. When the grounding device 501 is pulled out from the array antenna 400, a connector seal element 504 can be used to achieve a sealed connection between the grounding device 501 and the housing of the array antenna 400, and further achieve sealing protection of the components within the housing of the array antenna 400.

[0054] Please refer to the diagram of the internal architecture of the array antenna 400 in the present application shown in FIG. 2. A radiating unit 401, a metal reflecting panel 402, and a phase shifter 403 are arranged inside the box of the array antenna 400 in the present application. The radiating unit 401 is located on one side of the metal reflecting panel 402 and forms at least one independent radiating array together with the metal reflecting panel 402. The radiating unit 401 is an antenna element that transmits or receives radio waves. The frequencies of the multiple radiating units 401 in the independent radiating array may be the same or different to accommodate the reception and transmission of radio waves in different frequency bands. The metal reflecting panel 402 is the radiating unit 401When located on one side of the radiating unit 401, the metal reflective panel 402 can reflect the wireless signal and enable the wireless signal to be aggregated on the radiating unit 401 to enhance the wireless signal received by the radiating unit 401. The metal reflective panel 402 is further configured to reflect the wireless signal at the radiating unit 401 to transmit the wireless signal to the outside and enhance the strength of the signal transmitted by the radiating unit 401. Furthermore, the metal reflective panel 402 is further configured to block or shield the wireless signal from the other side (i.e., the reverse direction) of the radiating unit 401 to avoid interference of the wireless signal from the other side to the radiating unit 401.

[0055] The phase shifter 403 in the array antenna 400 may be understood to be the phase shifter in the present application. The phase shifter 403 is electrically connected to the radiating unit 401, and one side of the phase shifter 403 remote from the radiating unit 401 is further connected to the antenna interface 406, and is connected to a building baseband processing unit (not shown) of the base station through the antenna interface 406. The building baseband processing unit of the base station may be configured to generate a signal. After the phase assignment is performed on the signal by the phase shifter 403, the signal is transmitted to the radiating unit 401 to be transmitted to the outside. Alternatively, the building baseband processing unit is configured to receive the wireless signal transmitted by the radiating unit 401, and the wireless signal is obtained through the phase processing performed by the phase shifter 403. The phase shifter 403 in the present application is configured to perform phase adjustment on the wireless signal, change the tilt of the wireless signal beam, and optimize the communication network. Furthermore, functional components such as a transmitting or calibration network 404 and a combiner or filter 405 may be further disposed within the array antenna 400 and are separately configured to perform operations such as calibrating the radio signals and adjusting the amplitude of the radio signals.

[0056] Please refer to the schematic diagram of the structure of the phase shifter 403 in the present application shown in FIG. 3. The phase shifter 403 may include a feeding stripline 100 and a sliding medium 301. The sliding medium 301 may slide against the feeding stripline 100 and adjust the phase of the phase shifter 403 by changing the electrical length of the feeding stripline 100. In the phase shifter 403 in the present application, the feeding stripline 100 may be configured to realize the function of a power divider. In other words, the sliding medium 301 slides against the power divider formed by the feeding stripline 100 and changes the phase output of the phase shifter 403. In some other embodiments, it can be understood that the feeding stripline 100 provided in the present application may further be used as a coupler, electronic tilt, filter, etc., and used in the base station of the present application to realize functions such as microwave radio signal transmission and / or phase adjustment.

[0057] In this specification of the present application, in order to facilitate the description of the embodiment, the implementation is described in detail using the feeding stripline 100 as a power divider in the phase shifter 403. Furthermore, in this application, the feeding stripline 100 is further disposed in a shielded cavity to form a structure of a suspended stripline 300.

[0058] Please further refer to FIG. 3 and the schematic diagram of the suspension stripline 300 in the present application shown in FIG. 4. The suspension stripline 300 includes a cavity 200 and a feed stripline 100. The feed stripline 100 is located in the cavity 200 and fixed relative to the cavity 200. The feed stripline 100 is further insulatedly connected to the cavity 200. In some embodiments, a quarter-wavelength lightning shorting line for protection may be further disposed between the feed stripline 100 and the cavity 200. In one embodiment, the feed stripline 100 is integrally accommodated in the cavity 200. In addition, as can be seen from FIG. 4, the feed stripline 100 extends into the cavity 200 mainly along a first direction 001, and the first direction 001 may be defined as the main extension direction of the feed stripline 100.

[0059] The cavity 200 has electromagnetic shielding performance and can be used as a ground structure of the powered stripline 100. In addition, the cavity 200 shields external signal interference to ensure the electrical signal transmission of the powered stripline 100. In other words, the cavity 200 is used as a shielding cavity of the powered stripline 100. In one embodiment, the cavity 200 may be an integrally sealed structure, and the stripline 100 is housed in the integrally sealed cavity 200 to achieve a better shielding effect. In some other embodiments, a via 204 may be disposed in the cavity 200, as shown in FIG. 3 and FIG. 4. Specifically, in the cavity 200 shown in FIG. 3 and FIG. 4, the cavity 200 has an upper surface (not shown) and a lower surface 201 disposed opposite to each other, and a side surface 202 connected between the upper surface and the lower surface 201. There are two side surfaces 202, and the two side surfaces 202 are also arranged on two opposite sides of the stripline 100. The top surface, the bottom surface 201, and the two side surfaces 202 all extend along a first direction 001, and the cavity 200 is a structure in which a via 203 is provided in the length extension direction (first direction 001) of the power feed stripline 100. In other words, the cavity 200 forms a through structure in the length extension direction (first direction 001) of the power feed stripline 100, and the via 203 penetrates the cavity 200 along the first direction 001. Both of the cavities 200 of the two structures can achieve a reliable shielding effect for the power feed stripline 100. In addition, the cavity 200 provided with the vias 203 is more convenient to be manufactured by using molding processes such as extrusion and casting, and also facilitates the assembly of the power stripline 100 within the cavity 200.

[0060] The sliding medium 301 is slidably connected in the cavity 200 and located on one side of the feeding stripline 100. As shown in FIG. 3 and FIG. 4, the sliding medium 301 is located vertically above the feeding stripline 100. The sliding medium 301 can slide relative to the cavity 200 to adjust the position of the sliding medium 301 relative to the feeding stripline 100. Different positions of the sliding medium 301 relative to the feeding stripline 100 change the equivalent dielectric constant of the feeding stripline 100 accordingly. In other words, sliding the sliding medium 301 relative to the feeding stripline 100 can change the electrical length of the feeding stripline 100, and further change the phase output of the feeding stripline 100. In one embodiment, the sliding medium 301 slides relative to the feed stripline 100 along the extension direction of the feed stripline 100 (first direction 001) to achieve a phase shift effect over a wider range of the feed stripline 100.

[0061] Please refer to Fig. 4 further. The power feed stripline 100 includes a signal input line 150 and at least two power branches. As shown in Fig. 4, the at least two power branches include four power branches, a first power branch 110, a second power branch 120, a third power branch 130, and a fourth power branch 140. The power feed stripline 100 further includes a signal input port 101 and a signal output port 102. There are also multiple signal output ports 102, and each power branch is connected to one signal output port 102. As shown in FIG. 4, the first power branch line 110 is connected to the first signal output port 1021, the second power branch line 120 is connected to the second signal output port 1022, the third power branch line 130 is connected to the third signal output port 1023, and the fourth power branch line 140 is connected to the fourth signal output port 1024.

[0062] One end of the signal input line 150 is connected to the signal input port 101. The signal input line 150 receives or transmits a signal through the signal input port 101. In this embodiment of the present application, the signal input port 101 and the signal output port 102 may be independent interface structures. The signal input port 101 may also be defined as one end of the signal input line 150, and the signal output port 102 may also be defined as one end of the power branch line. It may be understood that notches (not shown) corresponding to the signal input port 101 and the signal output port 102 may be further disposed on the cavity 200 to realize signal transmission between the power feed stripline and the outside.

[0063] One end of the signal input line 150 remote from the signal input port 101 is conducted to a plurality of power branches. As shown in FIG. 4, the end of the signal input line 150 remote from the signal input port 101 is conducted to the first power branch 110, the second power branch 120, the third power branch 130, and the fourth power branch 140. In addition to the body 153 connected to the signal input port 101, the signal input line 150 further includes a first input segment 151 and a second input segment 152 separately connected to the body 153. One side of the body 153 remote from the signal input port 101 is initially connected to the first input segment 151 and the second input segment 152. After the first input segment 151 and the second input segment 152 extend separately in different directions, one end of the first input segment 151 far from the signal input port 101 is connected to the first power branch 110 and the second power branch 120, and one end of the second input segment 152 far from the signal input port 101 is connected to the third power branch 130 and the fourth power branch 140. In this way, an electrical signal input from the signal input port 101 can enter the power feed stripline 100 from the body 153 and then be transmitted to the power branches via the first input segment 151 and the second input segment 152.

[0064] It should be noted that the first input segment 151 and the second input segment 152 are used as connecting lines connecting the body 153 and the power branches, and may be considered as parts of the power branches. In other words, the first input segment 151 may also be considered as a line extending to the body 153 after the first power branch 110 and the second power branch 120 are coupled, and the second input segment 152 may also be considered as a line extending to the body 153 after the third power branch 130 and the fourth power branch 140 are coupled. The first input segment 151 and the second input segment 152 are simply used as two connecting segment structures in the power feed stripline 100. The specific homing division of the first input segment 151 and the second input segment 152 does not affect the functional implementation of the power feed stripline 100 in this application.

[0065] It can be understood that when the power feed stripline 100 includes four power branch lines, if the four power branch lines are directly conducted to the signal input line 150, in other words, if the four power branch lines are directly connected to the body 153 of the signal input line 150, when the electrical signal flows from the body 153 to the power branch lines, a phenomenon occurs in which the electrical signal flows from a large line width to a narrow line width, which does not lead to impedance matching of the power feed stripline 100. The first input segment 151 and the second input segment 152 can be arranged to provide a transition for the line width change on the transmission path of the electrical signal, so as to reduce the loss caused by the line width change in the transmission process of the electrical signal.

[0066] In another embodiment, the power feed stripline 100 of the present application is not limited to the arrangement of two input segments, the first input segment 151 and the second input segment 152. If the power feed stripline 100 includes more than four power branches, more input segments can be further arranged to be connected to different power branches. Alternatively, if there are two or three power branches of the power feed stripline 100, the input segment transition structure may not be arranged, and the first power branch 110 and the second power branch 120 are directly connected to the signal input line 150 (as shown in FIG. 5a and FIG. 5b), or the first power branch 110, the second power branch 120, and the third power branch 130 are connected to the signal input line 150 (as shown in FIG. 5c) to realize the phase allocation function of the power feed stripline 100 of the present application.

[0067] As shown in the implementations of Figures 5a, 5b, and 5c, at the location where the signal input line 150 is separately conducted to the first power branch 110 and the second power branch 120 (which may further include a third power branch 130 in Figure 5c), the signal sent by the signal input line 150 may be separately conducted to the first power branch 110 and the second power branch 120 (which may further include a third power branch 130), and the signal received by the signal input line 150 may also be separately obtained via the first power branch 110 and the second power branch 120 (which may further include a third power branch 130). The location where the signal input line 150 is connected to the first power branch 110 and the second power branch 120 (which may further include a third power branch 130) is a power splitter.

[0068] Please refer to FIG. 4. The first input segment 151 and the second input segment 152 have different extension lengths. Accordingly, the first power branch 110 and the second power branch 120 also have different extension lengths, and the equivalent dielectric constants of the first power branch 110 and the second power branch 120 are also different. The phase of the electrical signal flowing through the first input segment 151 and the first power branch 110 to the first signal output port 1021 is different from the phase of the electrical signal flowing through the first input segment 151 and the second power branch 120 to the second signal output port 1022. Accordingly, the third power branch 130 The extension lengths of the first and fourth power branch lines 140 are also different, and the phases of the third and fourth signal output ports 1023 and 1024 are also different. In this way, after an electrical signal flows from the signal input port 101 into the power feed strip line 100, when the electrical signal travels through different power branch lines to reach different signal output ports 102, the phases of the electrical signal are different.

[0069] Referring to FIG. 3, the phase shifter 403 In the case of , the sliding medium 301 further covers the first input segment 151, the second input segment 152, and each power branch. As described above, each power branch extends mainly along the first direction 001. After the first input segment 151 and the second input segment 152 are arranged to extend mainly along the first direction 001, the sliding medium 301 may cover the first input segment 151, the second input segment 152, and each power branch along the first direction 001. In this case, the sliding medium 301 slides relative to the cavity 200, and the lengths of the first input segment 151 and the second input segment 152 correspondingly covered by the sliding medium 301, and the lengths of each power branch correspondingly covered by the sliding medium 301 also change synchronously.

[0070] When the sliding medium 301 covers the first input segment 151 and the first power branch 110, the equivalent dielectric constant of the covering portion of the first input segment 151 and the first power branch 110 may change. When the equivalent dielectric constants of the first input segment 151 and the first power branch 110 change synchronously under the action of the sliding medium 301, the actual electrical length from the signal input port 101 to the first signal output port 1021 is also adjusted accordingly. It can be understood that the sliding of the sliding medium 301 further synchronously changes the covering length of the sliding medium 301 relative to the second power branch 120, causing the adjustment of the equivalent dielectric constant of the second power branch 120 and the corresponding adjustment of the electrical length of the second power branch 120. Furthermore, the electrical lengths of the third power branch 130 and the fourth power branch 140 are adjusted synchronously. In this application, the phase shifter 403 By sliding the sliding medium 301, the phase angle difference between the first output port 1021, the second output port 1022, the third output port 1023, and the fourth output port 1024 can be changed, thereby realizing the function of adjusting the phase angle of the electrical signal.

[0071] It can be understood that when electrical signals are input separately from the first output port 1021, the second output port 1022, the third output port 1023, and the fourth output port 1024 and transmitted to the signal input port 101, the electrical signal acquired by the signal input port 101 also undergoes phase adjustment due to the difference in electrical length between the first power branch line 110, the second power branch line 120, the third power branch line 130, and the fourth power branch line 140.

[0072] 3, it should be noted that the sliding medium 301 covers the first input segment 151, the second input segment 152, and each of the power branches. In some other embodiments, the sliding medium 301 may alternatively cover only the first input segment 151 and the second input segment 152, and adjust the phase difference between the signal output ports 102 by changing the electrical lengths of the first input segment 151 and the second input segment 152. Alternatively, the sliding medium 301 may cover only the first power branch 110, the second power branch 120, the third power branch 130, and the fourth power branch 140, and adjust the phase difference between the signal output ports 102 by changing the electrical lengths of the power branches.

[0073] Please refer to the schematic diagram of the structure of the power strip line 100 on one side of the first output segment 151 shown in FIG. 6. The first power branch 110 and the second power branch 120 are further arranged on the side of the first output segment 151. The first power branch 110 is cut into a first segment 10 and a second segment 20 along the extending direction of the first power branch 110. The first segment 10 is located on the side closer to the first output segment 151 and is connected to the first output segment 151. The second segment 20 is located on the side closer to the first signal output port 1021. In addition, the first segment 10 and the second segment 20 are distributed to two opposite sides of the second power branch 120. In other words, the first segment 10 includes a first end 11 that is far from the first output segment 151 along the extension direction of the first segment 10, the first end 11 being close to the second power branch 120 and located on one side of the second power branch 120, and the second segment 20 includes a second end 21 that is close to the second power branch 120, the second end 21 also being close to the second power branch 120 and located on the other side of the second power branch 120 with respect to the first end 11. The first segment 10 and the second segment 20 are distributed on two sides of the second power branch 120 and are disconnected from each other.

[0074] The first power branch 110 further includes a jump structure 30, which is located between the first segment 10 and the second segment 20 and spaced apart from the second power branch 120. The jump structure 30 is fixed relative to the first segment 10 and the second segment 20 and configured to provide a signal transmission function between the first segment 10 and the second segment 20. Specifically, the first power branch line 110 is cut into a first segment 10 and a second segment 20 spaced apart from each other, so that after the electrical signal transmitted on the first power branch line 110 reaches the first end 11, the signal at the first end 11 is transmitted to the second end 21 under the action of the jump structure 30 fixed relative to the first segment 10 and the second segment 20, and the electrical signal is further transmitted to the first signal output port 1021 via the second segment 20, thereby realizing the function of transmitting an electrical signal throughout the first power branch line 110.

[0075] Please refer to the structure of the existing power feed stripline 100a shown in FIG. 7. The existing power feed stripline 100a also includes an existing signal input line 150a, two existing output segments 151a, and a number of existing power branch lines 110a, and the existing signal input line 150a, the two existing output segments 151a, and the number of existing power branch lines 110a are all located in the same plane. The lines do not cross. In particular, at a position corresponding to one side of the first output segment 151 in the power feed stripline 100 in this application, the existing output segment 151a is also connected to the two existing power branch lines 110a. In addition, since the two existing power branch lines 110a do not cross, there is an idle area 103a in the existing power feed stripline 100a that cannot be used. In order to reach a preset extension length, the two existing power branch lines 110a can only extend to the area where the two power branch lines are located separately, forming a relative phase difference. It can be understood that when the two existing power branch lines 110a extend separately to the area where the two power branch lines are located separately, the area required by the two power branch lines 110a increases corresponding to the length required for extension. Referring to the area of ​​the idle area 103a formed because the existing power branch lines 110a cannot cross, the overall area of ​​the existing power feed strip line 100a increases accordingly, which is not conducive to the size control of the power feed strip line 100a. The larger the size, the more the transportation and installation costs of the existing power feed strip line 100a increase. In addition, the volume of products such as existing phase shifters, array antennas, and base stations that use the existing power feed strip line 100a also increases accordingly, which is also not conducive to transportation and installation.

[0076] However, in the present application, the feeding stripline 100 cuts the first power branch 110 into a first segment 10 and a second segment 20 independent of each other, and realizes signal transmission between the first segment 10 and the second segment 20 through the jump structure 30, so that the first segment 10 and the second segment 20 can be separately positioned on two opposite sides of the second power branch 120. In this way, the extension area of ​​the first power branch 110 is extended and the idle area is eliminated. The overall size of the feeding stripline 100 in the present application is controlled, and the transportation and installation costs of the feeding stripline 100 in the present application are reduced.

[0077] In particular, in the structure of the suspended stripline 300 provided in the embodiment of the present application, the internal space of the cavity 200 is limited by cost and processing. After the structure of the feeding stripline 100 in the present application is used, the plane area ratio of the feeding stripline 100 in the present application is small, so the size of the feeding stripline 100 can be compressed on the premise of implementing the same tilt, so that the overall volume of the suspended stripline 300 in the present application can also be controlled.

[0078] It can be understood that since the feeding stripline 100 in the present application is used or included, the phase shifter 403, the array antenna 400, and the base station in the present application each have a smaller volume, and the transportation and installation costs are also reduced.

[0079] It can be understood that for the multiple power branches in the power feed stripline 100, the jump structure 30 is provided, and the specific number of the power branches crossing another power branch is not limited in the present application. In other words, based on the specific extension length requirement of each power branch in the power feed stripline 100, the number of the multiple power branches cut into two relative segments connected via the jump structure 30 can be set randomly. For example, the jump structure 30 may be arranged for the third power branch 130, so that the third power branch 130 can extend to two opposite sides of the fourth power branch 140, and the second power branch 140 can be connected to the fourth power branch 140, which is the same as the second power branch 140 in the present application. input The area utilization is improved on the side of the feed stripline 100 closer to the segment 152. This application only illustrates the embodiment in which one of the multiple power branches includes the jump structure 30.

[0080] In another embodiment, for the first power branch 110, a third segment (not shown) obtained by cutting may be further arranged based on the first power branch 110 being cut into the first segment 10 and the second segment 20, and the third segment and the second segment 20 are cut from each other, and the third segment and the first segment 10 are located on one side of the second power branch 120. In this case, the signal transmission function between the second segment 20 and the third segment may also be realized through the jump structure 30, and the cable wiring form in which the first power branch 110 crosses the second power branch 120 twice does not lead to the arrangement of the first power branch 110. It may be understood that the first power branch 110 may further include disconnected structures such as a fourth segment and a fifth segment, and the first power branch 110 may be used with multiple jump structures 30 to achieve crossing of the first power branch 110 with the second power branch 120. The specific arrangement scheme may be determined based on the extension length and operational requirements of the first power branch 110.

[0081] In a possible implementation, to facilitate synchronous manufacturing of the first segment 10, the second segment 20, the signal input line 150, and the second power branch 120, both the signal input line 150 and the second power branch 120 are located in a first plane (not shown), and the first segment 10 and the second segment 20 of the first power branch 110 are also located in the first plane. The jump structure 30 is at least partially located outside the first plane to achieve mutual isolation between the jump structure 30 and the second power branch 120.

[0082] Please refer to the implementation of the jump structure 30 shown in Figures 8 and 9. As shown in Figures 8 and 9, the jump structure 30 is configured in the form of a bridge jumper 31. The jumper 31 is conductive and includes a connection segment 313, a first pin 311, and a second pin 312. The first pin 311 and the second pin 312 are distributed to two opposite ends of the connection segment 313, in other words, the connection segment 313 is connected between the first pin 311 and the second pin 312. The length direction of the connection segment 313 is arranged along the extension direction of the first power branch 110, and the first pin 311 is located on the side closer to the first segment 10, and the second pin 312 is located on the side closer to the second segment 20. The connection segment 313 and the second power branch 120 are arranged at an interval. The connection segment 313 is connected between the connection segment 313 and the first segment 10 via a first pin 311, and is fixed and conductive with respect to the first segment 10. The connection segment 313 is further connected between the connection segment 313 and the second segment 20 via a second pin 312, and is fixed and conductive with respect to the second segment 20.

[0083] In one implementation, the first pin 311, the second pin 312, and the connection segment 313 are of a unitary structure, i.e., the jump structure 30 is integrally formed. In this case, the connection between the connection segment 313 and the first pin 311 and the second pin 312 is more stable. This improves the reliability of the first power branch 110.

[0084] The specific shape of the jump structure 30 is not particularly limited in the embodiment of the present application. The jump structure 30 may be a circular arc intersecting with the second power branch 120, or may be any curved shape. As long as the jump structure is separated from the second power branch 120 and realizes the electrical connection between the first segment 10 and the second segment 20, the jump structure may be used as the jump structure in the powered strip line 100 in the present application. In an embodiment, the connection segment 313 is further located in a second plane, and the first plane is parallel to the second plane. Therefore, in the process of the connection segment 313 intersecting with the second power branch 120, the height difference between the connection segment 313 and the second power branch 120 is always stable. This helps to control the signal interference between the connection segment 313 and the second power branch 120.

[0085] As shown in FIG. 8 and FIG. 9, the first pin 311 can be fixed and conducted relatively to the first segment 10 by welding, and the second pin 312 can also be fixed and conducted relatively to the second segment 20 by welding. Solder 50 is further laminated between the jumper 31 and the first segment 10 and between the jumper 31 and the second segment 20. After reaching the first end 11, the electrical signal input from the first segment 10 is transmitted to the connection segment 313 through the first pin 311, and then transmitted to the second pin 312 through the connection segment 313 after crossing the two power branch lines 120. Finally, the electrical signal is transmitted from the second pin 312 through the second end 21 to the second segment 20 and output from the first signal output port 1021. On the contrary, when an electrical signal is input from the first signal output port 1021, the electrical signal is transmitted through the second segment 20 to the second pin 312, the connection segment 313, the first pin 311, the first segment 10, and finally to the signal input line 150 through the power distributor. The bridge jumper 31 is disposed above the first plane, crosses the second power branch line 120, and then is connected to and conducted by the first segment 10 and the second segment 20, thereby achieving the effect of transmitting an electrical signal between the first segment 10 and the second segment 20.

[0086] In the embodiment of FIG. 8 and FIG. 9, a first opening 111 is further disposed at the first end 11, and the appearance of the first opening 111 is disposed corresponding to the appearance of the first pin 311 so that the first pin 311 can pass through the first opening 111 (see FIG. 10). In this case, the first pin 311 can be separately welded and fixed to two opposing surfaces of the first segment 10 to further improve the stability of the connection between the first pin 311 and the first segment 10. In addition, the first opening 111 can be further configured to position the jumper 31 relative to the first segment 10. Accordingly, a second opening 211 is also disposed at the second end 21, and the appearance of the second opening 211 also matches the appearance of the second pin 312, and the second pin 312 can pass through the second opening 211 and be welded and fixed to two opposing surfaces of the second segment 20. The second opening 211 may also be used for positioning between the jumper 31 and the second segment 20 .

[0087] In one implementation, the jumper 31 is elastic. When the first pin 311 and the second pin 312 of the jumper 31 extend into the first opening 111 and the second opening 211, respectively, elastic deformation occurs between the first pin 311 and the second pin 312, and an elastic force F1 (see FIG. 11 ) is formed between the first pin 311 and the second pin 312, which draws them together. The elastic force F1 allows the first pin 311 to abut against an inner wall on one side of the first opening 111, and the second pin 312 to abut against an inner wall on one side of the second opening 211, so that the jumper 31 can maintain a reliable contact with the first segment 10 and the second segment 20. In this case, the jumper 31 can be abutted against the first segment 10 and the second segment 20, and can be welded based on the elastic jumper 31. Both can ensure reliable overlapping contact between the first pin 311 and the first opening 111 and between the second pin 312 and the second opening 211 .

[0088] It can be understood that when elastic deformation occurs between the first pin 311 and the second pin 312, a pulling elastic force F2 can be further formed between the first pin 311 and the second pin 312, and beneficial effects similar to those of the above-mentioned embodiment can also be achieved.

[0089] In another aspect, in addition to welding or butted conduction, the first pin 311 and the first segment 10 may alternatively be butted together in a manner such as buckling and gluing. Correspondingly, the second pin 312 and the second segment 20 may be butted together in a manner such as buckling and gluing. This does not affect the functional implementation of the powered stripline 100 in this application.

[0090] In one embodiment, the line width of the connection segment 313 is equal to or less than the line width of the first segment 10 and the second segment 20 This can be used to control the impedance matching between the jumper 31 and the first and second segments 10 and 20 to reduce losses in the jumper 31 and improve the overall electrical performance of the first power branch 110.

[0091] 12 and 13 show another embodiment of the jump structure 30. As shown in FIG. 12 and FIG. 13, the jump structure 30 is configured as a patch 32. The patch 32 includes a first coupling end 321, a second coupling end 322, and a connection segment 313 connected between the first coupling end 321 and the second coupling end 322. The patch 32, the first segment 10, and the second segment 20 are separately disposed, and the protrusion of the first coupling end 321 on the first plane at least partially overlaps with the first end 11. Thus, the first end 11 and the first coupling end 321 can form a coupled electrical connection, and the electrical signal on the first segment 10 is transmitted to the first coupling end 321 in a coupled manner. Similarly, the protrusion of the second coupling end 322 on the first plane also at least partially overlaps with the second end 21. Thus, the second coupling end 322 can transmit the electrical signal in a coupled manner to the second end 21 , where the electrical signal is further transmitted through the second segment 20 .

[0092] In one implementation, a first coupling capacitor is formed between the first coupling end 321 and the first segment 10, and a second coupling capacitor is formed between the second coupling end 322 and the second segment 20. The capacitor structure is formed by connecting the jump structure 30 to the first segment 10 and the second segment 20. 20 and the coupling electrical connections are implemented in the form of a first coupling capacitor and a second coupling capacitor. In some other embodiments, the coupling may alternatively be implemented between the first coupling end 321 and the first segment 10 and between the second coupling end 322 and the second segment 20 by forming an inductance.

[0093] See the embodiment of Fig. 14. In the jump structure 30 in the form of the patch 32, an isolation pad 324 is further sandwiched between the patch 32 and the first power branch 110. The isolation pad 324 is an insulating material and can be formed by injection molding. The isolation pad 324 is configured to perform insulation and fixation between the patch 32 and the first power branch 110 to form the first coupling capacitor and the second coupling capacitor.

[0094] Specifically, there are two isolation pads 324, which are separately located between the first coupling end 321 and the first segment 10 and between the second coupling end 322 and the second segment 20. The second end 12 and the first coupling end 321 of the first segment 10 are spaced apart, and the isolation pad 324 is configured to fixedly support the first coupling end 321. In one embodiment, the two isolation pads 324 are separately located at the first end 11 and the second end 21, and the first coupling end 321 is fixedly connected to the isolation pad 324 located at the first end 11, and the second coupling end 322 is fixedly connected to the isolation pad 324 located at the second end 21.

[0095] The power feed stripline 100 in the above embodiment is expanded based on the structure of a metal sheet strip. In some other embodiments, the power feed stripline 100 may alternatively be a PCB (Printed Circuit Board) strip fabricated on a printed circuit board, or another strip form.

[0096] Please refer to the structure shown in Figure 15 and Figure 16. The feed stripline 100 further includes a printed circuit board 40. When the feed stripline 100 is placed in the cavity 200 and forms a suspended stripline 300 together with the cavity 200, the printed circuit board 40 is further fixed in the cavity 200. The signal input line 150, the second power branch 120, the first power branch 110, and the jump structure 30 are all located on the printed circuit board 40. The printed circuit board 40 can form a solid support for the feed stripline 100 and realize the insulation and fixation of the feed stripline 100 to the cavity 200 in the implementation of the suspended stripline 300.

[0097] For details, please refer to FIG. 17. The printed circuit board 40 has a first outer surface 41. The signal input line 150, the second power branch 120, the first segment 10, and the second segment 20 are all attached to the first outer surface 41 and configured as a first plane on the first outer surface 41. In other words, the first plane formed by configuring the signal input line 150, the second power branch 120, the first segment 10, and the second segment 20 is attached to the first outer surface 41. The printed circuit board 40 further includes a second outer surface 42, which is disposed opposite the first outer surface 41. The connection segment 313 may be attached to the second outer surface 42 and configured to form a second plane (not shown) on the second outer surface 42. In other words, the second plane formed by configuring the connection segment 313 is attached to the second outer surface 42. In this way, the first plane and the second plane are formed as two metal surfaces arranged opposite to each other on the printed circuit board 40, with the first plane configured as the first metal surface and the second plane configured as the second metal surface. As shown in Fig. 17, the connection segment 313 and the second outer surface 42 are spaced apart from each other, and the signal transmission function of the jump structure 30 can also be realized.

[0098] In some other embodiments, grooves (not shown) may be further disposed on the first outer surface 41 and the second outer surface 42 accordingly. The grooves are configured to accommodate the lines of the power feed stripline 100, such that at least a portion of the lines of the power feed stripline 100 are accommodated in the grooves. In this case, the bottom surface of the power feed stripline 100 is lower than the first outer surface 41 and the second outer surface 42. In some embodiments, when the power feed stripline 100 is fully accommodated in the grooves, the top surface of the power feed stripline 100 is further flush with the first outer surface 41 and the second outer surface 42. These embodiments are all possible implementations of the PCB strip, and also implementations in which the power feed stripline 100 in this application is positioned on the printed circuit board 40.

[0099] See Fig. 16. The via 43 is disposed on the printed circuit board 40, passes through the first outer surface 41 and the second outer surface 42, and is connected between the first plane and the second plane. The first pin 311 and the second pin 312 are separately configured as conductive elements passing through the via 43, and are connected between the first segment 10 on the first plane and the connection segment 313 on the second plane, and between the second segment 20 on the first plane and the connection segment 313 on the second plane. The via 43 can be manufactured on the printed circuit board 40 by using an existing process, and then the first pin 311 and the second pin 312 are disposed to pass through the via 43 separately, so that the jump structure 30 can reliably overlap each of the first segment 10 and the second segment 20.

[0100] As shown in FIG. 16, the jump structure 30 is still arranged as a jumper 31. The first pin 311 and the second pin 312 of the jumper 31 pass through the via 43 separately, and are fixed and conducted to the first segment 10 and the second segment 20 by welding, respectively, to achieve the purpose of signal transmission. It can be understood that in the embodiment of FIG. 16, the via 43 is also configured to form the structure of the first opening 111 and the second opening 211. As shown in FIG. 17, the jumper 31 extends from the second outer surface 42 side of the printed circuit board 40 into the via 43, and extends from the first outer surface 41 side to the outside. In this case, the first segment 10 and the second segment 20 are fixed by welding to the first pin 311 and the second pin 312, respectively, on the first outer surface 41 side, and the first pin 311 and the second pin 312 are further firmly connected to the first segment 10 and the second segment 20 under the cooperative action of the welding and the via 43.

[0101] In some other implementations, the vias 43 may alternatively be separately configured as conductive vias (not shown). In this case, the vias 43 are filled with a conductive material such as metal. When the connection segment 313 is attached to the second outer surface 42 and the first segment 10 and the second segment 20 are attached to the first outer surface 41, the connection segment 313 is electrically connected to the first segment 10 and the second segment 20 through the conductive vias. In some other embodiments, the jump structure 30 is arranged as a patch 32. The patch 32 is configured as a second plane and attached to the second outer surface 42. The patch 32 performs signal transmission through coupling with the first segment 10 and the second segment 20, so that the function of transmitting a signal is also realized by the first power branch 110.

[0102] Please refer to the embodiment shown in FIG. 18. An input matching line 152, a first power matching line 112, and a second power matching line 122 are further disposed in the second metal surface. The input matching line 152, the first power matching line 112, and the second power matching line 122 are all attached to the second outer surface 42. Furthermore, the input matching line 152 extends parallel to the signal input line 150, the first power matching line 112 extends parallel to the first power branch 110, and the second power matching line 122 extends parallel to the second power branch 120. It can be understood that the input matching line 152 is also connected to the first power matching line 112 and the second power matching line 122. In addition, as shown in FIG. 18, the first power matching line 112 is also in a disconnected state, and the disconnection position of the first power matching line 112 corresponds to the disconnection position between the first segment 10 and the second segment 20 in the first power branch line 110.

[0103] In this case, on the extension path of the signal input line 150, the signal input line 150 and the input matching line 152 work together to transmit the electrical signal sent by the signal input port 101. The second power matching line 122 and the second power branch line 120 also work together to transmit the electrical signal to the second signal output port 1022. The first power matching line 122 and the first power branch line 110 work together with the jump structure 30 to transmit the electrical signal to the first signal output port 1021. As shown in FIG. 18, the jump structure 30 is configured in the form of a jumper 31. The jumper 31 passes through the via 43, contacts the first power branch line 110 and the first power matching line 112, and is conductive to both the first power branch line 110 and the first power matching line 112. In this way, the function of transmitting the electrical signal on the first power branch line 110 and the first power matching line 112 is realized.

[0104] In one embodiment, the printed circuit board 40 may further include a plurality of vias 43. The plurality of vias 43 are all conductive vias, are distributed at intervals along the extending direction of the signal input line 150, and are configured to connect the signal input line 150 and the input matching line 152, form an electrical path between the signal input line 150 and the input matching line 152, and perform impedance matching between the signal input line 150 and the input matching line 152. The plurality of vias 43 may further be disposed between the first power branch 110 and the first power matching line 112 and / or between the second power branch 120 and the second power matching line 122, form an electrical path between the two power branches and the matching lines corresponding to the two power branches, and adjust the equivalent dielectric constant of each of the two power branches.

[0105] For one embodiment, please refer to Fig. 19 and the plan view of the first metal surface shown in Fig. 20 and the plan view of the second metal surface shown in Fig. 21. As shown in Fig. 21, the first power matching line 112 is in a coherent connection state, and the connection segment 313 is configured as part of the line structure in the first power matching line 112. Furthermore, as shown in Fig. 21, the second power matching line 122 includes a third segment 123 and a fourth segment 124. The third segment 123 is located on one side of the connection segment 313 and extends parallel to the second power branch 120. The fourth segment 124 is located on the other side of the connection segment 313 and also extends parallel to the second power branch 120. In other words, the first power branch 110 is in a cut state on the first metal plane, and the cut first segment 10 and second segment 20 are distributed to two sides of the second power branch 120. The second power matching line 122 is also in a cut state on the second metal plane, and the cut third segment 123 and fourth segment 124 are distributed to two sides of the first power matching line 120. 112 are distributed on two sides.

[0106] A plurality of vias 43 are disposed between the first power branch 110 and the first power matching line 112, and the vias 43 are conductive vias, so that the connection segment 313 configured as a part of the line structure in the first power matching line 112 realizes the function of transmitting the electrical signal on the first segment 10 to the second segment 20 through the vias 43 distributed on two sides of the second power branch 120, and can further realize the transmission of the electrical signal on the first power branch 110. A plurality of vias 43 are also disposed between the second power branch 120 and the second power matching line 122, and the plurality of vias 43 are distributed on two sides of the connection segment 313. In this case, the electrical signal on the third segment 123 can be transmitted to the second segment 20 through the vias 43 distributed on two sides of the second power branch 120. The number is After being transmitted to the second power branch 120 through the via 43, the electrical signal crosses the connection segment 313 with the second power branch 120 and is transmitted to the fourth segment 124 through the via 43 on the other side of the connection segment 313 to realize transmission of the electrical signal on the second power matching line 122.

[0107] Please refer to the structure shown in FIG. 22 and FIG. 23. At the position where the connection segment 313 intersects with the second power branch 120, an included angle α is formed between the protrusion of the connection segment 313 in the first plane and the second power branch 120, and the included angle α should satisfy the condition of 45°≦α≦90°. In the embodiment of FIG. 22 and FIG. 23, the included angle α=90°. The protrusion of the connection segment 313 in the first plane partially overlaps with the second power branch 120, and the overlapping area increases as the included angle α decreases. It indicates that the larger the overlapping area between the connection segment 313 and the second power branch 120, the larger the signal interference formed between the connection segment 313 and the second power branch 120. It can be understood that when the connection segment 313 is parallel to the second power branch 120, i.e., when the included angle α=0°, the connection segment 313 completely overlaps with the second power branch 120. In this case, the overlapping area between the connection segment 313 and the second power branch 120 is the largest, and the electrical signal interference between the connection segment 313 and the second power branch 120 is also the strongest. After the range of the included angle α is limited, the overlapping area between the connection segment 313 and the second power branch 120 may be controlled to be in a small range, and when the included angle α=90°, the overlapping area between the connection segment 313 and the second power branch 120 is the smallest. Such a setting can limit the signal interference between the connection segment 313 and the second power branch 120 and ensure the stable transmission of the respective electrical signals between the first power branch 110 and the second power branch 120.
