Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication, and more particularly to a feed line, a phase shifter configured with the feed line, an array antenna, and a base station. Background Technology
[0002] Feeder strips are common components in communication base stations, serving as radio frequency functional devices such as power dividers, couplers, filters, and power conditioners to transmit wireless microwave signals. Existing feeder strips are mostly planar structures. To ensure electrical performance, the various power branches extend along different transmission paths in the plane, avoiding crossings or overlaps that could cause signal series connection issues. Consequently, the planar area of the feeder strip is difficult to control, and some planar areas may become unusable, resulting in a large area proportion for the feeder strip, which is detrimental to the current trend of miniaturization in base stations and other communication equipment. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a three-dimensional feed line structure, and a phase shifter, array antenna, and base station including this three-dimensional feed line structure, thereby reducing the area ratio of the feed line. This application specifically includes the following technical solutions:
[0004] In a first aspect, this application provides a power supply line, including a signal input line, a first power branch and a second power branch. One end of the signal input line is connected to an external signal source, and the other end is electrically connected to the first power branch and the second power branch respectively. The first power branch includes a jumper structure, and the first power branch crosses from one side of the second power branch to the other side of the second power branch through the jumper structure. The jumper structure and the second power branch are spaced apart from each other.
[0005] In the power supply line of this application, the first power branch and the second power branch are respectively connected to the signal input line, so that the external electrical signal input from the signal input line can be transmitted to the first power branch and the second power branch respectively. The electrical signal can be transmitted on the extension path of the first power branch and the extension path of the second power branch respectively. After setting the extension lengths of the first power branch and the second power branch to be different from each other, the electrical signal output by the first power branch can form a phase difference with the electrical signal output by the second power branch, and a preset downtilt angle can be obtained accordingly.
[0006] This application's power supply line also utilizes a jumper structure on the first power branch line, allowing the first power branch line to extend a certain distance on one side of the second power branch line and then cross over to the other side to continue extending. The jumper structure is spaced apart from the second power branch line, meaning that the first power branch line will not overlap with the second power branch line when crossing from one side to the other, ensuring normal transmission of electrical signals on both lines. Simultaneously, the jumper structure expands the extension range of the first power branch line, improving the utilization rate of the power supply line's space area, thereby reducing the overall volume of the power supply line while maintaining its electrical functionality.
[0007] In one possible implementation, both the signal input line and the second power branch are located in a first plane. The first power branch includes a first segment and a second segment located in the first plane. The first segment and the second segment are distributed on opposite sides of the second power branch. The jumper structure includes a connecting segment located in the second plane. The connecting segment is electrically connected to the first segment and the second segment, respectively.
[0008] In this implementation, the first power branch is divided into two independent segments, the first and second, which are located on opposite sides of the second power branch. This allows the main structure of the first power branch, along with the signal input line and the second power branch, to lie within a first plane, forming the planar structure of the power supply line body of this application. This also facilitates the synchronous fabrication of the first segment, the second segment, the signal input line, and the second power branch. Connecting segments located in the second plane cooperate with the first and second segments respectively to achieve electrical signal transmission between them. This ensures that the switching structure, while spaced from the second power branch, guarantees electrical signal transmission on the first power branch.
[0009] In one possible implementation, the jump structure also includes a first pin and a second pin, which are distributed at opposite ends of the connecting segment. The connecting segment is connected to the first segment through the first pin, and the connecting segment is also connected to the second segment through the second pin.
[0010] In this implementation, the jumper structure further includes a first pin and a second pin at opposite ends of the distributed connecting segment. The first pin and the second pin are respectively connected between the first plane and the second plane to achieve contact and conduction between opposite ends of the connecting segment and the first segment and the second segment, respectively. The electrical signal transmitted on the first segment is transmitted sequentially through the first pin, the connecting segment, and the second pin to the second segment, and then continues to be transmitted through the second segment to the rear end of the first power branch.
[0011] In one possible implementation, the first foot, the second foot, and the connecting segment are a single integrated structure.
[0012] In this implementation, the jump structure is formed as a single unit, and the connection between the connecting segment and the first and second pins is more stable, thus improving the reliability of the first power branch.
[0013] In one possible implementation, the first leg is welded to the first segment, and the second leg is also welded to the second segment.
[0014] In this implementation, reliable contact and conductivity between the first leg and the first segment, as well as between the second leg and the second segment, can be ensured by welding.
[0015] In one possible implementation, the first segment includes a first end away from the signal input line, and the second segment includes a second end close to the first segment. A first opening and a second opening are respectively provided on the first end and the second end. A first leg extends into the first opening and contacts the first segment to conduct electricity, and a second leg extends into the second opening and contacts the second segment to conduct electricity.
[0016] In this implementation, a first opening is provided at a position near the second segment in the first segment, allowing the first leg to extend into the first opening; and a second opening is provided at a position near the first segment in the second segment, allowing the second leg to also extend into the second opening. This ensures reliable contact between the first leg and the first segment, as well as reliable contact between the second leg and the second segment.
[0017] In one possible implementation, the jump structure is elastic, and when the jump structure is inserted into the first opening and the second opening respectively, the first leg and the second leg undergo elastic deformation and have elastic forces that bring them closer together or spread them apart.
[0018] In this implementation, in addition to welding, the first leg and the first opening can also be reliably connected by elastic deformation; similarly, the second leg and the second opening can also be reliably connected by elastic deformation, in addition to welding. Furthermore, the first leg and the second leg have an elastic force that pulls them closer together or an elastic force that spreads them apart, allowing the elastic forces of the first leg and the second leg to interact and ensure reliable contact between each leg and the first and second openings.
[0019] In one possible implementation, the connecting segment includes opposing first coupling ends and second coupling ends, the projection of the first coupling end onto a first plane at least partially coincides with the first segment, and the first coupling end and the first segment are electrically connected by coupling.
[0020] The projection of the second coupling end onto the first plane at least partially coincides with the second segment, and the second coupling end and the second segment are also electrically connected by coupling.
[0021] In this implementation, the connecting segment does not contact the first segment or the second segment. Instead, it forms a mutually coupled structure with the first segment and the second segment through the first coupling end and the second coupling end, respectively. The electrical signal transmitted on the first segment is coupled to the jump structure and then coupled to the second segment again, thus realizing the function of the jump structure to transmit the electrical signal on the first segment to the second segment.
[0022] 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.
[0023] In this implementation, the jump structure forms a capacitor structure with the first segment and the second segment respectively, and the coupling electrical connection is achieved through the first coupling capacitor and the second coupling capacitor.
[0024] In one possible implementation, insulating spacers are filled between the first coupling end and the first segment, and between the second coupling end and the second segment.
[0025] In this implementation, the isolation pad can be formed by injection molding or other methods, thereby securing the first coupling end to the first segment and the second coupling end to the second segment. The isolation pad ensures the relative position of the jump structure with respect to the first and second segments, thus guaranteeing the stable electrical performance of the first and second coupling capacitors.
[0026] In one possible implementation, the power supply line includes a printed circuit board, which includes a first metal surface and a second metal surface disposed opposite to each other, the first metal surface being configured as a first plane and the second metal surface being configured as a second plane.
[0027] In this implementation, the power supply strip is fabricated on a printed circuit board (PCB) to form a PCB strip. The PCB has a first metal surface and a second metal surface opposite to each other. The first metal surface is configured as the first plane of the power supply strip. The signal input line, the first segment, the second segment, and the second power branch line can be disposed within the first metal surface, while the connection segment of the jumper structure can be disposed within the second metal surface. In this case, the second metal surface is configured as the second plane, and the PCB substrate can provide reliable support for the power supply strip.
[0028] In one possible implementation, the printed circuit board includes vias communicating between a first plane and a second plane, and the first pin and the second pin are respectively configured as conductive elements passing through the vias.
[0029] In this implementation, vias can be fabricated on a printed circuit board using existing technology. These vias connect the first and second planes, and by setting the via positions, they can be located between the connecting segment and the first segment, and between the connecting segment and the second segment. Then, a first pin and a second pin are respectively connected through the vias between the connecting segment and the first segment, and between the connecting segment and the second segment, thus achieving a reliable connection between the jump structure and the first and second segments respectively.
[0030] In one possible implementation, the first and second pins are respectively constructed as conductive materials filling the via; or,
[0031] The first leg and the second leg pass through the through hole and are fixedly connected to the first segment and the second segment respectively.
[0032] In this implementation, a conductive via is formed by filling the via with metal or other conductive material, thereby realizing the functions of the first and second pins and ensuring reliable connection between the connecting segment and the first and second segments respectively. The first and second pins can also be constructed as conductive elements, which pass through the via and connect between the connecting segment and the first segment, as well as between the connecting segment and the second segment, to realize the electrical signal transmission function of the jump structure between the first and second segments.
[0033] In one possible implementation, the second metal surface is further provided with an input matching line, a first power matching line, and a second power matching line;
[0034] The input matching line extends parallel to the signal input line, the first power matching line extends parallel to the first power branch, and the connecting segment is constructed as a part of the first power matching line;
[0035] The second power matching line includes a third segment and a fourth segment. The third segment is located on one side of the connecting segment and extends parallel to the second power branch line. The fourth segment is located on the other side of the connecting segment and also extends parallel to the second power branch line.
[0036] In this implementation, an input matching line is also provided on the second outer surface opposite to the first outer surface for the signal input line. The input matching line works together with the signal input line to transmit the electrical signal from the signal source. Simultaneously, a first power matching line and a second power matching line are also provided for the first power branch and the second power branch, respectively. The first power branch and the first power matching line work together to achieve the transmission of the electrical signal in the extension direction of the first power branch, and the second power branch and the second power matching line work together to achieve the transmission of the electrical signal in the extension direction of the second power branch. Due to the isolation characteristics of the first and second outer surfaces on the PCB, the positions of the lines on the two outer surfaces are relatively fixed, providing a basis for mutual cooperation to achieve signal conduction.
[0037] Understandably, when the first power matching line is disposed on the second outer surface, the connecting segment can be constructed as a part of the first power matching line, which is used to realize the transmission of electrical signals between the first segment and the second segment, as well as the transmission of electrical signals in the first power matching line.
[0038] In one possible implementation, vias on the printed circuit board may also be located between signal input lines and input matching lines, and / or between first power branches and first power matching lines, and / or between second power branches and second power matching lines, to form electrical paths between each line and its corresponding matching line and to adjust the equivalent dielectric constant.
[0039] In one possible implementation, the angle α between the projection of the connecting segment in the first plane and the second power branch satisfies the condition: 45°≤α≤90°.
[0040] In this implementation, because the connecting segment crosses the second power branch and is spaced apart from it, meaning the connecting segment and the second power branch intersect in space, the projection of the connecting segment onto the first plane will partially overlap with the second power branch. By setting the angle between the connecting segment and the second power branch, the overlap area between them can be controlled, thereby avoiding electrical signal interference caused by excessive overlap.
[0041] In one possible implementation, the first plane is parallel to the second plane.
[0042] In this implementation, the first plane is the plane where the second power branch is located, and the second plane is the plane where the connecting segment is located. Setting the first plane and the second plane to be parallel can ensure that the connecting segment maintains a stable height difference with the second power branch as it crosses over it, which is beneficial for controlling signal interference between the connecting segment and the second power branch.
[0043] In one possible implementation, the power supply line further includes a signal input port, a first output port, and a second output port. The end of the signal input line away from the first power branch and the second power branch is connected to the signal input port. The end of the first power branch away from the signal input line is connected to the first output port. The end of the second power branch away from the signal input line is connected to the second output port.
[0044] In this implementation, the signal input line is connected to the signal input port to receive the signal source. The first power branch and the second power branch output signals to the back end through their respective connected signal output ports, realizing the phase distribution function of the power supply line.
[0045] In one possible implementation, the power supply line further includes a shielded cavity, in which the input line, the first power branch line, and the second power branch line are all housed and fixed, and are insulated from the shielded cavity.
[0046] In this implementation, the power supply line is constructed as a suspended line, and the shielding cavity can shield external signal interference, reducing the signal loss of the power supply line transmitted within the shielding cavity.
[0047] Secondly, this application provides a phase shifter, including a sliding medium and a power supply line provided in the first aspect of this application. The sliding medium is connected to a first power branch and / or a second power branch, respectively. The sliding medium slides relative to the first power branch and / or the second power branch to adjust the phase of the phase shifter output signal.
[0048] In a second aspect of this application, the power feed line is used as a power divider in a phase shifter. By sliding the sliding medium relative to the power feed line, the electrical lengths of the first power branch and the second power branch can be changed, thereby adjusting the phase difference between the electrical signals transmitted in the first power branch and the second power branch.
[0049] Thirdly, this application provides an array antenna, including the feed strip provided in the first aspect of this application, and / or the phase shifter provided in the second aspect of this application.
[0050] Fourthly, this application also provides a base station, including the feed line provided in the first aspect of this application, and / or the phase shifter provided in the second aspect of this application, and / or the array antenna provided in the third aspect of this application.
[0051] In one possible implementation, the base station further includes an indoor baseband processing unit, a radio frequency remote unit, and an antenna feeder system. The feeder cable provided in the first aspect of this application, and / or the phase shifter provided in the second aspect of this application, and / or the array antenna provided in the third aspect of this application, are disposed in the antenna feeder system. The radio frequency remote unit is connected between the indoor baseband processing unit and the antenna feeder system, and the antenna feeder system is connected to the indoor baseband processing unit through the radio frequency remote unit to realize the wireless signal transmission and reception function.
[0052] As can be seen, the phase shifter, array antenna and base station provided in the second to fourth aspects of this application all use the feed line of this application. Therefore, like the feed line in the first aspect of this application, the planar utilization rate of the feed line can be improved by arranging the first power branch on both sides of the second power branch, thereby obtaining a feed line with a smaller volume ratio, which is also beneficial to the control of the overall volume of the products in various aspects.

[0076] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0077] The base stations involved in this application include indoor baseband processing units (BBU), remote radio units (RRU), and... Figure 1The antenna feeder system 500 is shown. The radio frequency remote unit is connected between the indoor baseband processing unit and the antenna feeder system 500. There can be multiple antenna feeder systems 500, and there can also be multiple radio frequency remote units. Each antenna feeder system 500 cooperates with one radio frequency remote unit. Multiple antenna feeder systems 500 are connected to an indoor baseband processing unit through their corresponding radio frequency remote units to realize the function of wireless signal transmission and reception.
[0078] Please see Figure 1 The diagram shows the structure of the antenna feeder system 500. The antenna feeder system 500 includes an array antenna 400, a mast 502, an antenna bracket 503, a connector seal 504, and a grounding device 501. The mast 502 is fixed relative to the ground, and the antenna bracket 503 connects the array antenna 400 and the mast 502, providing a fixed connection between the array antenna 400 and the mast 502. In some embodiments, the antenna bracket 503 can also be configured as an adjustable bracket, used to adjust the azimuth and angle of the array antenna 400 relative to the mast 502, thereby coordinating with the signal transmission angle of the array antenna 400 to ensure that the signal emitted by the antenna feeder system 500 forms a preset downtilt angle with the ground. The base station of this application can be installed in any public place or cell to achieve signal coverage in its corresponding area.
[0079] The array antenna 400 is the array antenna involved in this application. The array antenna 400 is also electrically connected to the grounding device 501 to achieve the grounding function of the array antenna 400. The end of the grounding device 501 furthest from the array antenna 400 can also be connected and fixed to a mounting pole 502, achieving the grounding function through the mounting pole 502. Understandably, the grounding device 501 can also be directly fixed to the ground to ensure the reliable grounding function of the array antenna 400. The array antenna 400 is typically housed in a sealed enclosure (antenna radome). This enclosure needs to possess sufficient mechanical strength and resistance to contamination and water to protect the internal components of the array antenna 400 from external environmental influences. Electrically, the enclosure needs to have good electromagnetic wave penetration characteristics to ensure the signal transmission and reception functions of the array antenna 400. A connector seal 504 can also be provided between the grounding device 501 and the enclosure of the array antenna 400. When the grounding device 501 is led out from the array antenna 400, it can achieve a sealed connection between itself and the housing of the array antenna 400 through the connector seal 504, thereby achieving sealed protection of the components inside the housing of the array antenna 400.
[0080] Please see Figure 2The diagram shows the internal architecture of the array antenna 400 involved in this application. Inside the housing of the array antenna 400, there are radiating elements 401, a metal reflector 402, and a phase shifter 403. The radiating elements 401 are located on one side of the metal reflector 402 and together with the metal reflector 402, form at least one independent radiating array. The radiating elements 401, also known as antenna elements, are used to transmit or receive radio waves. The frequencies of the multiple radiating elements 401 in the independent radiating array can be the same or different, thus corresponding to the transmission and reception of radio waves in different frequency bands. When the metal reflector 402 is located on one side of the radiating elements 402, it can reflect the radio signal and concentrate the radio signal on the radiating elements 401 to enhance the radio signal received by the radiating elements 401; the metal reflector 402 is also used to reflect and transmit the radio signal at the radiating elements 401 outward to enhance the strength of the signal emitted by the radiating elements 401. Furthermore, the metal reflector 402 is also used to block or shield wireless signals from the other side (i.e., the opposite direction) of the radiating unit 401, so as to prevent the wireless signals from the other side from interfering with the radiating unit 401.
[0081] Understandably, the phase shifter 403 in the array antenna 400 is the same as the phase shifter involved in this application. The phase shifter 403 is electrically connected to the radiating unit 401, and the side of the phase shifter 403 facing away from the radiating unit 401 is also connected to the antenna interface 406, and through the antenna interface 406, it is connected to the indoor baseband processing unit of the base station (not shown in the figure). The indoor baseband processing unit of the base station can be used to generate signals, which are then transmitted to the radiating unit 401 for external transmission after phase distribution by the phase shifter 403; or, the indoor baseband processing unit can be used to receive the wireless signals transmitted by the radiating unit 401, and the wireless signals are processed by the phase shifter 403 according to a certain phase. In this application, the phase shifter 403 is used to adjust the phase of the wireless signal, thereby changing the downtilt angle of the wireless signal beam and optimizing the communication network. Furthermore, the array antenna 400 can also be equipped with functional devices such as a transmission or calibration network 404, and a combiner or filter 405, which are used for operations such as calibrating the wireless signal and adjusting the amplitude of the wireless signal.
[0082] Please see Figure 3The diagram shows the structure of the phase shifter 403 of this application. The phase shifter 403 may include a feed line 100 and a sliding medium 301. The sliding medium 301 can slide relative to the feed line 100, thereby adjusting the phase of the phase shifter 403 by changing the electrical length of the feed line 100. Within the phase shifter 403 of this application, the feed line 100 can be used to implement the function of a power divider. That is, the sliding medium 301 slides relative to the power divider composed of the feed line 100 to change the phase output of the phase shifter 403. It is understood that in other embodiments, the feed line 100 provided in this application can also be used as a coupler, power conditioner, or filter, and applied in the base station involved in this application to realize functions such as microwave wireless signal transmission and / or phase adjustment.
[0083] In this application specification, for the convenience of describing the various embodiments, the power supply line 100 is used as a power divider in the phase shifter 403 to describe the various implementation methods. Furthermore, the power supply line 100 of this application is also disposed in a shielded cavity, forming a structure for suspending the line 300.
[0084] Please continue reading Figure 3 and simultaneously combined Figure 4 This is a schematic diagram of the suspended wire 300 of this application. The suspended wire 300 includes a cavity 200 and a feed wire 100. The feed wire 100 is located within the cavity 200 and fixed relative to the cavity 200. The feed wire 100 is also insulated from the cavity 200. In some embodiments, a 1 / 4 wavelength lightning protection short-circuit line may also be provided between the feed wire 100 and the cavity 200 for protection. In one embodiment, the feed wire 100 is entirely housed within the cavity 200. Figure 4 It can be seen that the power supply line 100 extends mainly along the first direction 001 within the cavity 200, and the first direction 001 can also be defined as the main extension direction of the power supply line 100.
[0085] The cavity 200 has electromagnetic shielding properties, serving as a grounding structure for the feed line 100 and simultaneously shielding against external signal interference, ensuring the electrical signal transmission of the feed line 100. That is, the cavity 200 is used as a shielding cavity for the feed line 100. In one embodiment, the cavity 200 can be a completely sealed structure, with the feed line 100 housed within the sealed cavity 200, achieving better shielding. In other embodiments, the cavity 200 can be as follows... Figure 3 and Figure 4 The diagram shows a through-hole 204. Specifically, in... Figure 3 and Figure 4In the schematic cavity 200, the cavity 200 has an opposing upper surface (not shown) and a lower surface 201, and a side surface 202 connecting the upper and lower surfaces 201. There are two side surfaces 202, which are also located on opposite sides of the feed line 100. The upper surface, lower surface 201, and both side surfaces 202 extend along a first direction 001. In the length extension direction (first direction 001) of the feed line 100, the cavity 200 has a through-hole 203. That is, the cavity 200 forms a through structure in the direction along the length extension direction (first direction 001) of the feed line 100, and the through-hole 203 penetrates the cavity 200 along the first direction 001. Both types of cavity 200 can provide reliable shielding for the power supply line 100. The cavity 200 with through hole 203 is also easy to manufacture using molding processes such as extrusion and casting, and is also convenient for assembling the power supply line 100 in the cavity 200.
[0086] The sliding medium 301 is slidably connected within the cavity 200 and located on one side of the power supply line 100. Figure 3 and Figure 4 In the schematic diagram, the sliding medium 301 is located vertically above the feed line 100. The sliding medium 301 can slide relative to the cavity 200 and adjust its relative position with the feed line 100. Different relative positions of the sliding medium 301 and the feed line 100 will cause a corresponding change in the equivalent dielectric constant of the feed line 100, that is, the sliding of the sliding medium 301 relative to the feed line 100 can change the electrical length of the feed line 100, thereby changing the phase output of the feed line 100. In one embodiment, the sliding medium 301 slides relative to the feed line 100 along the extension direction (first direction 001) of the feed line 100 to form a larger range of phase shift effect on the feed line 100.
[0087] Please continue reading Figure 4 The power supply line 100 includes a signal input line 150 and at least two power branches. Figure 4 In the schematic diagram, at least two power branches are included, comprising 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 supply line 100 also includes a signal input port 101 and a signal output port 102. There are multiple signal output ports 102, and each power branch is connected to one signal output port 102. Figure 4 In the diagram, the first power branch 110 is connected to the first signal output port 1021, the second power branch 120 is connected to the second signal output port 1022, the third power branch 130 is connected to the third signal output port 1023, and the fourth power branch 140 is connected to the fourth signal output port 1024.
[0088] One end of the signal input line 150 is connected to the signal input port 101. The signal input line 150 receives or transmits signals through the signal input port 101. In this embodiment, the signal input port 101 and the signal output port 102 can be independent interface structures. The signal input port 101 can also be defined as one end of the signal input line 150, and the signal output port 102 can also be defined as one end of the power branch line. It is understood that notches (not shown in the figure) corresponding to the positions of the signal input port 101 and the signal output port 102 can also be provided on the cavity 200 to realize signal transmission between the power supply line and the outside.
[0089] The end of signal input line 150 furthest from signal input port 101 is connected to multiple power branches. Figure 4 In the schematic diagram, the end of the signal input line 150 away from the signal input port 101 is connected to the first power branch 110, the second power branch 120, the third power branch 130, and the fourth power branch 140, respectively. In addition to the main body 153 connected to the signal input port 101, the signal input line 150 also includes a first input segment 151 and a second input segment 152, which are respectively connected to the main body 153. The side of the main body 153 away from the signal input port 101 is first 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 in different directions, the end of the first input segment 151 away from the signal input port 101 is connected to the first power branch 110 and the second power branch 120, respectively, while the end of the second input segment 152 away from the signal input port 101 is connected to the third power branch 130 and the fourth power branch 140, respectively. Thus, the electrical signal transmitted from the signal input port 101 can enter the power supply line 100 from the main body 153, and then be transmitted to each power branch line via the first input section 151 and the second input section 152 respectively.
[0090] It should be noted that the first input segment 151 and the second input segment 152, as connecting lines between the main body 153 and each power branch line, can also be considered as part of each power branch line. That is, the first input segment 151 can also be considered as a line extending towards the main body 153 after the first power branch line 110 and the second power branch line 120 are merged, and the second input segment 152 can also be considered as a line extending towards the main body 153 after the third power branch line 130 and the fourth power branch line 140 are merged. The first input segment 151 and the second input segment 152 only serve as two connecting segments in the feeder line 100, and their specific classification does not affect the functional realization of the feeder line 100 of this application.
[0091] Understandably, when the power supply line 100 includes four power branches, if these four power branches are directly connected to the signal input line 150 (i.e., if the four power branches are directly connected to the main body 153 of the signal input line 150), the electrical signal will flow from a larger line width to a narrower line width when it travels from the main body 153 to each power branch. This is detrimental to the impedance matching of the power supply line 100. The configuration of the first input segment 151 and the second input segment 152 can provide a transition in line width variation along the path of electrical signal transmission, reducing signal loss caused by line width variation during transmission.
[0092] On the other hand, the power supply line 100 of this application is not limited to the configuration of only two input segments: the first input segment 151 and the second input segment 152. When the power supply line 100 includes four or more power branches, more input segments can be configured to connect to different power branches respectively. Alternatively, when the power supply line 100 has two or three power branches, a transition structure for the input segments may not be required, and the first power branch 110 and the second power branch 120 can be directly connected to the signal input line 150 (e.g., ...). Figure 5a , Figure 5b (as shown), or connect the first power branch 110, the second power branch 120, and the third power branch 130 to the signal input line 150 (as shown). Figure 5c As shown, all of them can realize the function of 100 phase allocation of the power supply line in this application.
[0093] exist Figure 5a , Figure 5b and Figure 5c In the illustrations of various implementation methods, at the positions where the signal input line 150 is connected to the first power branch 110 and the second power branch 120 respectively ( Figure 5c It also includes a third power branch 130. The signal emitted by the signal input line 150 can be conducted to the first power branch 110 and the second power branch 120 (which may also include the third power branch 130), respectively. The signal received by the signal input line 150 can also be obtained through the first power branch 110 and the second power branch 120 (which may also include the third power branch 130), respectively. The position where the signal input line 150 connects with the first power branch 110 and the second power branch 120 (which may also include the third power branch 130) is the power divider.
[0094] Please see back Figure 4The first input segment 151 and the second input segment 152 have different extension lengths, which, in conjunction with the inconsistent extension lengths of the first power branch 110 and the second power branch 120, results in differences in their equivalent dielectric constants. Consequently, 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 differs 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. Correspondingly, the extension lengths of the third power branch 110 and the fourth power branch 140 are also inconsistent, leading to different phases at the third signal output port 1023 and the fourth signal output port 1024. Therefore, after the electrical signal flows from the signal input port 101 into the feed line 100, its phase differs as it travels through different power branches to reach different signal output ports 102.
[0095] Please see back Figure 3 In the phase shifter 300 of this application, the sliding medium 301 also simultaneously covers the first input segment 151, the second input segment 152, and each power branch line. As mentioned above, each power branch line mainly extends along the first direction 001. After setting the first input segment 151 and the second input segment 152 to also mainly extend along the first direction 001, the sliding medium 301 can simultaneously cover the first input segment 151, the second input segment 152, and each power branch line along the first direction 001. At this time, the sliding of the sliding medium 301 relative to the cavity 200 causes its corresponding length covering the first input segment 151 and the second input segment 152, as well as its corresponding length covering each power branch line, to change synchronously.
[0096] The sliding medium 301 covers the first input segment 151 and the first power branch 110, changing the equivalent dielectric constant of the covered portion. 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 is understandable that the sliding of the sliding medium 301 also synchronously changes its coverage length over the second power branch 120, causing an adjustment in the equivalent dielectric constant of the second power branch 120, and consequently adjusting 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 also adjusted synchronously. The phase shifter 400 of this application, through the sliding of the sliding medium 301, can change 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, thereby achieving the function of adjusting the phase angle of the electrical signal.
[0097] Understandably, when electrical signals are input and transmitted to signal input port 101 from the first output port 1021, the second output port 1022, the third output port 1023, and the fourth output port 1024 respectively, the electrical signals obtained by signal input port 101 will also undergo phase adjustment due to the difference in electrical length of the first power branch 110, the second power branch 120, the third power branch 130, and the fourth power branch 140.
[0098] It should be noted that, Figure 3 In the schematic structure, the sliding medium 301 simultaneously covers the first input segment 151, the second input segment 152, and each power branch. In other embodiments, the sliding medium 301 may cover only the first input segment 151 and the second input segment 152, adjusting the phase difference at each signal output port 102 by changing the electrical length of the first input segment 151 and the second input segment 152; or, 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, adjusting the phase difference at each signal output port 102 by changing the electrical length of each power branch.
[0099] Please see Figure 6 The diagram shows the structure of the power supply line 100 on one side of the first output section 151. A first power branch 110 and a second power branch 120 are also provided on one side of the first output section 151. The first power branch 110 is broken into a first segment 10 and a second segment 20 along its extension direction. The first segment 10 is located near the first output section 151 and is connected to it. The second segment 20 is located near the first signal output terminal 1021. The first segment 10 and the second segment 20 are distributed on opposite sides of the second power branch 120. Specifically, the first segment 10 includes a first end 11 extending away from the first output section 151, and this first end 11 is close to and located on one side of the second power branch 120; the second segment 20 includes a second end 21 close to the second power branch 120, and this second end 21 is also close to the second power branch 120, and is located on the other side of the second power branch 120 compared to the first end 11. The first segment 10 and the second segment 20 are distributed on both sides of the second power branch 120 and are disconnected from each other.
[0100] The first power branch 110 also includes a jumper structure 30, which is located between the first segment 10 and the second segment 20 and is spaced apart from the second power branch 120. The jumper structure 30 is fixed relative to the first segment 10 and the second segment 20 respectively, and is used to realize the signal transmission function between the first segment 10 and the second segment 20. Specifically, because the first power branch 110 is broken into the first segment 10 and the second segment 20 that are spaced apart, after the electrical signal reaches the first end 11 on the first power branch 110, it is transmitted to the second end 21 by the jumper structure 30, which is fixed relative to the first segment 10 and the second segment 20 respectively. The signal is then further transmitted to the first signal output port 1021 via the second segment 20, thus realizing the transmission function of the electrical signal on the entire first power branch 110.
[0101] Please see Figure 7 The existing power supply line 100a is shown in the diagram. The existing power supply line 100a also includes an existing signal input line 150a, two existing output sections 151a, and multiple existing power branches 110a, all of which are located in the same plane. There is no intersection between the lines. Specifically, on the side corresponding to the first output section 151 in the power supply line 100a, the existing output section 151a is also connected to two existing power branches 110a. Because the two existing power branches 110a do not intersect, there is an unusable idle area 103a in the existing power supply line 100a. To achieve the preset extension length, these two existing power branches 110a can only extend within their respective areas, thus creating a relative phase difference. Understandably, when the two existing power branches 110a extend within their respective areas, the required area increases accordingly with the length of extension. Considering the area of the unused region 103a formed because the existing power branches 110a cannot intersect, the overall area of the existing feed line 100a also increases, which is detrimental to the size control of the feed line 100a. The larger size also increases the transportation and installation costs of the existing feed line 100a, and the volume of existing phase shifters, array antennas, and base stations using the existing feed line 100a also increases accordingly, which is also detrimental to transportation and installation.
[0102] The power supply line 100 of this application, by breaking the first power branch line 110 into two independent segments, a first segment 10 and a second segment 20, and using a jumper structure 30 to achieve signal transmission between the first segment 10 and the second segment 20, allows the first segment 10 and the second segment 20 to be located on opposite sides of the second power branch line 120, thereby widening the extension area of the first power branch line 110 and eliminating the existence of idle areas. The overall size of the power supply line 100 of this application is controlled, and the transportation and installation costs of the power supply line 100 of this application are reduced.
[0103] Especially in the structure of the suspension line 300 provided in the embodiment of this application, the internal space of the cavity 200 is relatively limited due to cost and processing technology. After adopting the structure of the power supply line 100 of this application, because the planar area of the power supply line 100 of this application is smaller, the size of the power supply line 100 can be compressed under the premise of achieving the same downward tilt angle, so that the overall volume of the suspension line 300 of this application can also be controlled.
[0104] Understandably, because the use or inclusion of the feed line 100 of this application results in a smaller size for the phase shifter 403, the array antenna 400, and the base station, and also reduces transportation and installation costs.
[0105] It is understood that, for the multiple power branches in the feeder line 100, this application does not limit the specific number of power branches equipped with the jumper structure 30 and crossing another power branch. That is, based on the specific extension length requirements of each power branch in the feeder line 100, the number of power branches that are broken into two relative segments and connected by the jumper structure 30 can be arbitrarily set. For example, the third power branch 130 can also be equipped with the jumper structure 30 so that the third power branch 130 can extend on opposite sides of the fourth power branch 140, thereby improving the area utilization rate of the feeder line 100 near the second transmission section 152. This application only illustrates an embodiment in which one of the multiple power branches includes the jumper structure 30.
[0106] On the other hand, for the first power branch 110, it can be further divided into a third segment (not shown in the figure) in addition to being broken into a first segment 10 and a second segment 20. The third segment is disconnected from the second segment 20, and both the third segment and the first segment 10 are located on the same side of the second power branch 120. In this case, signal transmission can also be achieved between the second segment 20 and the third segment through a jump structure 30. Furthermore, the routing of the first power branch 110 crossing the second power branch 120 twice is more conducive to the arrangement of the first power branch 110. It is understandable that the first power branch 110 can also be divided into a fourth segment, a fifth segment, etc., and multiple jump structures 30 can be used to achieve the crossing of the first power branch 110 relative to the second power branch 120. The specific configuration can be based on the extension length of the first power branch 110 and the operational requirements.
[0107] In one possible implementation, both the signal input line 150 and the second power branch 120 are located within a first plane (not shown in the figure), and the first segment 10 and the second segment 20 of the first power branch 110 are also located within the first plane, thereby facilitating the synchronous fabrication of the first segment 10, the second segment 20, the signal input line 150, and the second power branch 120. 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.
[0108] Please see Figure 8 and Figure 9 One implementation of the jump structure 30 shown. Figure 8 and Figure 9 In the schematic diagram, the jumper structure 30 is constructed as a bridging jumper 31. The jumper 31 is conductive and includes a connecting segment 313, a first pin 311, and a second pin 312. The first pin 311 and the second pin 312 are distributed at opposite ends of the connecting segment 313, that is, the connecting segment 313 is connected between the first pin 311 and the second pin 312. The length direction of the connecting segment 313 is arranged along the extension direction of the first power branch line 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 connecting segment 313 and the second power branch line 120 are spaced apart. The connecting segment 313 is connected to the first segment 10 through the first pin 311 and is fixedly conductive relative to the first segment 10; the connecting segment 313 is also connected to the second segment 20 through the second pin 312 and is fixedly conductive relative to the second segment 20.
[0109] In one implementation, the first pin 311, the second pin 312, and the connecting segment 313 are integrated into a single structure, meaning the jumper structure 30 is integrally formed. In this case, the connection between the connecting segment 313 and the first pin 311 and the second pin 312 is more stable, improving the reliability of the first power branch line 110.
[0110] This application does not impose a specific limitation on the shape of the jumper structure 30. The jumper structure 30 can be an arc shape that crosses the second power branch line 120, or any other curved shape. As long as the jumper structure is isolated from the second power branch line 120 and achieves an electrical connection between the first segment 10 and the second segment 20, it can be used as the jumper structure in the feed line 100 of this application. In one embodiment, the connecting segment 313 is also located in the second plane, and the first plane is parallel to the second plane. Thus, the connecting segment 313 maintains a stable height difference with the second power branch line 120 during the process of crossing the second power branch line 120, which is beneficial for controlling signal interference between the connecting segment 313 and the second power branch line 120.
[0111] exist Figure 8 and Figure 9 In the diagram, the first pin 311 can be fixed and connected to the first segment 10 by soldering, and the second pin 312 can also be fixed and connected to the second segment 20 by soldering. Solder 50 is also piled between the jumper 31 and the first segment 10 and the second segment 20. After the electrical signal input from the first segment 10 reaches the first terminal 11, it can be transmitted to the connecting segment 313 through the first pin 311, and then across the second power branch line 120 through the connecting segment 313 to the second pin 312. Finally, it is transmitted from the second pin 312 to the second segment 20 through the second terminal 21 and output from the first signal output port 1021. Conversely, when the electrical signal is input from the first signal output port 1021, it can be transmitted sequentially through the second segment 20 to the second pin 312, the connecting segment 313, the first pin 311, and the first segment 10, and finally transmitted to the signal input line 150 through the power divider. The bridging jumper 31 is suspended on the first plane and crosses the second power branch line 120, and then connects to the first segment 10 and the second segment 20 respectively, achieving the effect of transmitting electrical signals between the first segment 10 and the second segment 20.
[0112] exist Figure 8 and Figure 9 In the embodiment, a first opening 111 is also provided at the first end 11. The shape of the first opening 111 corresponds to the shape of the first leg 311, so that the first leg 311 can pass through the first opening 111 (see...). Figure 10At this point, the first support leg 311 can be welded and fixed to the opposite sides of the first segment 10, further improving the stability of the connection between the first support leg 311 and the first segment 10. Simultaneously, the first opening 111 can also be used for positioning the jumper 31 relative to the first segment 10; correspondingly, a second opening 211 is also provided at the second end 21, the shape of which matches the second support leg 312. The second support leg 312 can pass through the second opening 211 and be welded and fixed to the opposite sides of the second segment 20. The second opening 211 can also be used for positioning the jumper 31 and the second segment 20.
[0113] In one implementation, the spring clip 31 is elastic. When the first leg 311 and the second leg 312 of the spring clip 31 are respectively inserted into the first opening 111 and the second opening 211, elastic deformation occurs between the first leg 311 and the second leg 312, and an elastic force F1 is formed between the first leg 311 and the second leg 312 to move towards each other (see...). Figure 11 The elastic force F1 causes the first leg 311 to make abutting contact with one side of the inner wall of the first opening 111, and simultaneously causes the second leg 312 to make abutting contact with one side of the inner wall of the second opening 211. It also maintains reliable contact between the spring clip 31 and the first segment 10 and the second segment 20. At this time, the spring clip 31 can abut against the first segment 10 and the second segment 20 respectively, or it can be welded onto the elastic spring clip 31, both ensuring reliable overlapping contact between the first leg 311 and the second leg 312 and the first opening 111 and the second opening 211 respectively.
[0114] It is understandable that when elastic deformation occurs between the first leg 311 and the second leg 312, a relatively expanding elastic force F2 can also be formed between the first leg 311 and the second leg 312, which can also achieve the same beneficial effect as the above embodiment.
[0115] On the other hand, in addition to welding or overlapping for conduction, the first leg 311 and the first segment 10 can also be overlapped by snapping or bonding; correspondingly, the second leg 312 and the second segment 20 can also be overlapped by snapping or bonding, which does not affect the functional realization of the power supply line 100 of this application.
[0116] In one embodiment, the line width of the connecting segment 313 can also be set to be less than or equal to the line width of the first segment 10, and simultaneously less than or equal to the line width of the second segment 10. This is used to control the impedance matching between the jumper 31 and the first segment 10 and the second segment 20, thereby reducing the loss at the jumper 31 and improving the overall electrical performance of the first power branch 110.
[0117] Figure 12 and Figure 13 Another embodiment of the jump structure 30 is illustrated. Figure 12 and Figure 13 In the schematic diagram, the jump structure 30 is constructed as a patch 32. The patch 32 includes a first coupling end 321 and a second coupling end 322, as well as a connecting segment 313 connecting the first coupling end 321 and the second coupling end 322. The patch 32 is separated from both the first segment 10 and the second segment 20. The projection 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 can be transmitted to the first coupling end 321 through coupling. Similarly, the projection of the second coupling end 322 on the first plane also at least partially overlaps with the second end 21, so the second coupling end 322 can transmit the electrical signal to the second end 21 through coupling, and further transmit the electrical signal via the second segment 20.
[0118] In one implementation, a first coupling capacitor is formed between the first coupling terminal 321 and the first segment 10, and a second coupling capacitor is formed between the second coupling terminal 322 and the second segment 20. The jump structure 30 forms a capacitor structure with the first segment 10 and the second segment 10 respectively, and the coupling electrical connection is achieved through the first coupling capacitor and the second coupling capacitor. In other embodiments, coupling between the first coupling terminal 321 and the first segment 10, and between the second coupling terminal 322 and the second segment 20, can also be achieved by forming an inductor.
[0119] Please see Figure 14 An embodiment is described. In the jumper structure 30 in the form of a patch 32, an insulating pad 324 is also sandwiched between the patch 32 and the first power branch line 110. The insulating pad 324 is an insulating material and can be injection molded. The insulating pad 324 is used to achieve insulation fixation between the patch 32 and the first power branch line 110 to form a first coupling capacitor and a second coupling capacitor.
[0120] Specifically, there are two isolation pads 324, located between the first coupling end 321 and the first segment 10, and between the second coupling segment 322 and the second segment 20, respectively. The first coupling end 321 and the second end 12 of the first segment 10 are spaced apart from each other, and the isolation pads 324 are used to fix and support the first coupling end 321. In one embodiment, the two isolation pads 324 are located at the first end 11 and the second end 21, respectively. 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.
[0121] The power supply strip 100 in the above embodiments is based on the structure of sheet metal strip. In other embodiments, the power supply strip 100 may also be a PCB strip fabricated on a printed circuit board, or other types of strip.
[0122] Please see Figure 15 and Figure 16 The schematic structure is shown. The power supply line 100 also includes a printed circuit board 40. When the power supply line 100 is placed inside the cavity 200 and forms a suspended line 300 together with the cavity 200, the printed circuit board 40 is also fixed inside the cavity 200. The signal input line 150, the second power branch line 120, the first power branch line 110, and the jumper structure 30 are all located on the printed circuit board 40. The printed circuit board 40 can provide reliable support for the power supply line 100 and achieve insulation and fixation of the power supply line 100 relative to the cavity 200 in the embodiment of the suspended line 300.
[0123] For details, please refer to the following: Figure 17 The printed circuit board 40 has a first outer surface 41. Signal input line 150, second power branch line 120, first segment 10, and second segment 20 are all attached to the first outer surface 41, forming a first plane on the first outer surface 41. That is, the first plane formed by the signal input line 150, second power branch line 120, first segment 10, and second segment 20 is attached to the first outer surface 41. The printed circuit board 40 also includes a second outer surface 42, which is disposed opposite to the first outer surface 41. A connecting segment 313 can be attached to the second outer surface 42, forming a second plane (not shown). That is, the second plane formed by the connecting segment 313 is attached to the second outer surface 42. Thus, the first plane and the second plane form two opposing metal surfaces on the printed circuit board 40, wherein the first plane is constructed as a first metal surface, and the second plane is constructed as a second metal surface. Figure 17 In the illustration, the position of the connecting segment 313 is spaced apart from the second outer surface 42, which can also realize the signal transmission function of the jump structure 30.
[0124] In other embodiments, grooves (not shown) may be correspondingly formed on the first outer surface 41 and the second outer surface 42. These grooves are used to accommodate each line of the power supply strip 100, such that each line of the power supply strip 100 is at least partially accommodated in the groove. In this case, the bottom surface of the power supply strip 100 will be lower than the first outer surface 41 and the second outer surface 42. In some embodiments, when the power supply strip 100 can be completely accommodated in the groove, the top surface of the power supply strip 100 is also flush with the first outer surface 41 and the second outer surface 42. These embodiments are all possible implementations of PCB strips and also belong to one implementation of the power supply strip 100 located on the printed circuit board 40 in this application.
[0125] Please continue reading Figure 16 The printed circuit board 40 is provided with a via 43, which penetrates the first outer surface 41 and the second outer surface 42 and connects between the first plane and the second plane. The first pin 311 and the second pin 312 are respectively configured as conductive elements passing through the via 43, and connect between the first segment 10 on the first plane and the connecting segment 313 on the second plane, and between the second segment 20 on the first plane and the connecting segment 313 on the second plane. Using existing technology, the via 43 can be fabricated on the printed circuit board 40, and by setting the first pin 311 and the second pin 312 to pass through the via 43, a reliable connection can be achieved between the jump structure 30 and the first segment 10 and the second segment 20 respectively.
[0126] exist Figure 16 In the illustration, the jump structure 30 is still set as a jumper 31. The first pin 311 and the second pin 312 of the jumper 31 pass through the via 43 and are fixedly connected to the first segment 10 and the second segment 20 by soldering, thereby achieving the purpose of signal transmission. It is understandable that in Figure 16 In some embodiments, the via 43 is also used to form the structure of the first opening 111 and the second opening 211 described above. For example... Figure 17 As illustrated, the jumper 31 extends from one side of the second outer surface 42 of the printed circuit board 40 into the via 43 and extends out from one side of the first outer surface 41. At this time, the first segment 10 and the second segment 20 are respectively soldered and fixed to the first leg 311 and the second leg 312 on one side of the first outer surface 41. Under the combined action of soldering and via 43, the connection between the first leg 311 and the second leg 312 and the first segment 10 and the second segment 20 is more stable.
[0127] In some embodiments, the via 43 can also be constructed as a conductive via (not shown in the figure). In this case, the via 43 is filled with a conductive material, such as metal. When the connecting 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 conductive via enables the connecting segment 313 to be electrically connected to the first segment 10 and the second segment 20, respectively. In some embodiments, the jumper structure 30 is set as a patch 32. The patch 32 is constructed as a second plane and attached to the second outer surface 42. The patch 32 transmits signals to the first segment 10 and the second segment 20 through coupling, thus realizing the function of the first power branch 110 transmitting signals.
[0128] Please see Figure 18 In one embodiment shown, an input matching line 152, a first power matching line 112, and a second power matching line 122 are further provided within 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. Further, 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 line 110, and the second power matching line 122 extends parallel to the second power branch line 120. It is understood that the input matching line 152 is also connected to the first power matching line 112 and the second power matching line 122, respectively. Figure 18 In the illustration, the first power matching line 112 is also in a disconnected state, and its disconnection position corresponds to the disconnection position of the first segment 10 and the second segment 20 in the first power branch line 110.
[0129] At this time, along the extension path of signal input line 150, signal input line 150 and input matching line 152 work together to transmit the electrical signal sent to signal input port 101. Second power matching line 122 also works with second power branch line 120 to transmit the electrical signal to second signal output port 1022. First power matching line 122 and first power branch line 110 cooperate with jumper structure 30 to transmit the electrical signal to first signal output port 1021. Figure 18 In the schematic diagram, the jumper structure 30 is constructed in the form of a jumper 31. The jumper 31 passes through the via 43 and contacts the first power branch 110 and the first power matching line 112 respectively, and simultaneously conducts the first power branch 110 and the first power matching line 112, thereby realizing the transmission function of electrical signals on the first power branch 110 and the first power matching line 112.
[0130] In one embodiment, there may be multiple vias 43 on the printed circuit board 40. All vias 43 are conductive vias. The multiple vias 43 are spaced apart along the extension direction of the signal input line 150 and are used to connect the signal input line 150 and the input matching line 152 to form an electrical path between the signal input line 150 and the input matching line 152, thereby achieving impedance matching between the two. The multiple vias 43 may also be disposed between the first power branch line 110 and the first power matching line 112, and / or between the second power branch line 120 and the second power matching line 122, to form an electrical path between the two power branches and their corresponding matching lines, and to adjust their respective equivalent dielectric constants.
[0131] Please refer to one embodiment. Figure 19 See also Figure 20 The first metal surface shown and Figure 21 The plan view of the second metal surface is shown. Figure 21 In the illustration, the first power matching line 112 is continuous and unbroken, and the connecting segment 313 is constructed as a portion of the line structure within the first power matching line 112. Furthermore, in Figure 21 In the schematic diagram, 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 connecting segment 313 and extends parallel to the second power branch line 120. The fourth segment 124 is located on the other side of the connecting segment 313 and also extends parallel to the second power branch line 120. That is, the first power branch line 110 is in a broken state within the first metal surface, and the broken first segment 10 and the second segment 20 are distributed on both sides of the second power branch line 120; the second power matching line 122 is also in a broken state within the second metal surface, and the broken third segment 123 and the fourth segment 124 are distributed on both sides of the first power matching line 110.
[0132] Because multiple vias 43 are provided between the first power branch 110 and the first power matching line 112, and these vias 43 are conductive, the connecting segment 313, which is constructed as a part of the wire structure of the first power matching line 112, can transmit the electrical signal on the first segment 10 to the second segment 20 through the vias 43 distributed on both sides of the second power branch 120, thereby realizing the transmission of the electrical signal on the first power branch 110. Multiple vias 43 are also provided between the second power branch 120 and the second power matching line 122, and these vias 43 are distributed on both sides of the connecting segment 313. At this time, the electrical signal 123 on the third segment 123 can be transmitted through the vias 43 to the second power branch 120, then cross the connecting segment 313 with the second power branch 120, and be transmitted through the vias 43 located on the other side of the connecting segment 313 to the fourth segment 124, thereby realizing the transmission of the electrical signal on the second power matching line 122.
[0133] Please see also Figure 22 and Figure 23 In the schematic structure, at the position where the connecting segment 313 crosses the second power branch 120, the projection of the connecting segment 313 in the first plane forms an angle α with the second power branch 120, and the angle α needs to satisfy the condition: 45°≤α≤90°. Figure 22 and Figure 23 In this embodiment, the included angle α = 90°. The projection of the connecting segment 313 onto the first plane partially overlaps with the second power branch 120, and the area of this overlap increases as the included angle α decreases. The larger the overlap area between the connecting segment 313 and the second power branch 120, the greater the signal interference between them. It is understandable that when the connecting segment 313 and the second power branch 120 are parallel to each other, i.e., when the included angle α = 0°, the connecting segment 313 and the second power branch 120 completely overlap, at which point the overlap area is the largest, and the electrical signal interference between them is the strongest. By limiting the range of the included angle α, the overlap area between the connecting segment 313 and the second power branch 120 can be controlled to be within a relatively small range, and when the included angle α = 90°, the overlap area between the connecting segment 313 and the second power branch 120 is the smallest. This setting can limit the signal interference between the connecting segment 313 and the second power branch 120, ensuring the stable transmission of the electrical signals between the first power branch 110 and the second power branch 120.
