Phase shifter and antenna

Abstract

The present disclosure relates to a phase shifter and an antenna, and relates to the technical field of antennas. The phase shifter comprises a first carrier plate, a first conductor strip, a second conductor strip, a first rotating support and a first phase-shifting conductor strip. The first conductor strip, the second conductor strip and the first rotating support are arranged on a first surface. The first phase-shifting conductor strip is located on a side of the first rotating support facing the first surface and is connected to the first rotating support. The first phase-shifting conductor strip is coupled to the first conductor strip and is coupled to the second conductor strip. When the first rotating support drives the first phase-shifting conductor strip to rotate, a vertical projection of the first phase-shifting conductor strip on the first carrier plate coincides with a vertical projection of the second conductor strip on the first carrier plate at different positions, so as to change a signal transmission path between a first signal coupling end and a second signal coupling end. The phase shifter described above can facilitate maintenance of the first conductor strip and the second conductor strip.

Description

Technical Field

[0001] This disclosure relates to the field of antenna technology, and more particularly to a phase shifter and antenna. Background Technology

[0002] The phase shifter is a key component of an antenna. While the radiator's primary function is to transmit and receive electromagnetic waves, the phase shifter shifts the signal's phase by an angle. In related technologies, some of the phase shifter's traces are formed on the PCB (printed circuit board), making repair inconvenient. Utility Model Content

[0003] To address the aforementioned technical problems, this disclosure provides a phase shifter and an antenna.

[0004] This disclosure provides a phase shifter comprising: a first carrier plate, a first conductor strip, a second conductor strip, a first rotating support member, and a first phase-shifting conductor strip. The first carrier plate includes a first surface. The first conductor strip and the second conductor strip are spaced apart on the first surface, wherein the first conductor strip includes a first signal coupling terminal, and the second conductor strip includes a second signal coupling terminal. The first rotating support member is disposed on the first surface and rotatably connected to the first carrier plate. The first phase-shifting conductor strip is located on the side of the first rotating support member facing the first surface and is connected to the first rotating support member. The vertical projection of the first phase-shifting conductor strip on the first carrier plate overlaps with a portion of the vertical projection of the first conductor strip on the first carrier plate, and the first phase-shifting conductor strip is coupled to the first conductor strip. The vertical projection of the first phase-shifting conductor strip on the first carrier plate overlaps with a portion of the vertical projection of the second conductor strip on the first carrier plate, and the first phase-shifting conductor strip and the second conductor strip are coupled to each other. When the first rotating support drives the first phase-shifting conductor strip to rotate, the vertical projection of the first phase-shifting conductor strip on the first carrier plate coincides with the vertical projection of the second conductor strip on the first carrier plate at different positions, so that the first phase-shifting conductor strip and the second conductor strip are coupled and connected at different positions, thereby changing the signal transmission path between the first signal coupling end and the second signal coupling end.

[0005] This disclosure also provides an antenna comprising: a phase shifter and a radiator as provided in some of the above embodiments, wherein the radiator is connected to the phase shifter.

[0006] Compared with the prior art, the technical solution provided in this disclosure has the following advantages: In the phase shifter provided in this disclosure, since the first conductor strip and the second conductor strip are structures independent of the first carrier board, in the event of a problem with the first conductor strip and the second conductor strip, the first conductor strip and the second conductor strip can be repaired or replaced separately, thereby facilitating the repair of the first conductor strip and the second conductor strip. In addition, the first conductor strip and the second conductor strip are not formed using PCB etching process, which can reduce contamination. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0016] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0017] Figure 1 This is a schematic diagram of the antenna structure provided in an embodiment of this disclosure.

[0018] Please see Figure 1 The antenna 3000 may include a radiator 2000 and a phase shifter 1000, wherein the radiator 2000 and the phase shifter 1000 are connected.

[0019] The main function of the radiator 2000 is to emit and receive electromagnetic waves. Specifically, the radiator 2000 is responsible for converting electrical signals into electromagnetic waves and radiating them into space, or for converting received electromagnetic waves into electrical signals.

[0020] The function of phase shifter 1000 is to shift the phase of a signal by an angle.

[0021] In some examples, the phase shifter 1000 may include at least one port group, the port group including a positive port and a negative port, the antenna 3000 may also include a wire group, the wire group including a first coaxial cable and a second coaxial cable, and the radiator 1000 may include a first polarization terminal and a second polarization terminal, wherein the first coaxial cable is connected between the positive port and the first polarization terminal, and the second coaxial cable is connected between the negative port and the second polarization terminal.

[0022] For example, the phase shifter 1000 may include multiple port groups, and the number of radiators may be multiple. A port group can be connected to a radiator through a line group.

[0023] In related technologies, some of the traces in the phase shifter 1000 are formed in the PCB (printed circuit board), which makes maintenance inconvenient.

[0024] Based on this, this disclosure provides a phase shifter 1000.

[0025] Figure 2 This is a schematic diagram of the structure of the phase shifter 1000 provided in the embodiments of this disclosure. Figure 3 for Figure 2 Another schematic diagram of the phase shifter 1000 is shown. Figure 4 for Figure 2 Another structural schematic diagram of the phase shifter 1000 in the diagram.

[0026] Please see Figure 2 , Figure 3 and Figure 4The phase shifter 1000 includes: a first carrier plate 100, a first conductor strip 210, a second conductor strip 220, a first rotating support member 300, and a first phase-shifting conductor strip 400.

[0027] The first conductor strip 210, the second conductor strip 220, and the first phase-shifting conductor strip 400 can be used to form the positive electrode feed module of the phase shifter 1000, or they can be used to form the negative electrode feed module of the phase shifter 1000. The negative electrode feed module can include at least one positive electrode port. The positive electrode feed module is used to transmit signals to the radiator, and the negative electrode feed module is used to receive signals from the radiator. The negative electrode feed module can include at least one positive electrode port.

[0028] The first carrier plate 100 includes a first surface.

[0029] The first carrier plate 100 can support the first conductor strip 210, the second conductor strip 220, the first rotating support member 300, and the first phase-shifting conductor strip 400.

[0030] In some examples, the first carrier plate 100 is a plastic plate.

[0031] The first carrier plate 100 is made of plastic. Therefore, plastic plates with different dielectric constants can be used according to the power supply scheme of the phase shifter 1000, thereby improving the power supply efficiency of the phase shifter 1000.

[0032] A first conductor strip 210 and a second conductor strip 220 are spaced apart on a first surface, wherein the first conductor strip 210 includes a first signal coupling terminal and the second conductor strip 220 includes a second signal coupling terminal.

[0033] In the case where the first conductor strip 210, the second conductor strip 220 and the first phase-shifting conductor strip 400 can be used to form the positive electrode feeding module of the phase shifter 1000, the second signal coupling terminal can be used as the positive electrode port and the first signal coupling terminal is used to receive the radiated signal.

[0034] When the first conductor strip 210, the second conductor strip 220 and the first phase-shifting conductor strip 400 can be used to form the negative electrode feeding module of the phase shifter 1000, the second signal coupling terminal can be used as the negative electrode port and the first signal coupling terminal is used to radiate signals outward.

[0035] For example, the second conductor strip 220 is strip-shaped; for instance, the extended trajectory of the second conductor strip 220 may be arc-shaped.

[0036] The second conductor strip 220 may include two second signal coupling terminals, which are located at the two ends of the second conductor strip 220 respectively.

[0037] The first conductor strip 210 can be fixedly connected to the first carrier plate 100, or the first conductor strip 210 can be detachably connected to the first carrier plate 100.

[0038] The second conductor strip 220 can be fixedly connected to the first carrier plate 100, or the second conductor strip 220 can be detachably connected to the first carrier plate 100.

[0039] The first conductor strip 210 and the second conductor strip 220 can be made of conductive materials.

[0040] The first rotating support 300 is disposed on the first surface and is rotatably connected to the first carrier plate 100.

[0041] For example, the first rotating support 300 may include a plastic support structure, wherein the plastic support structure may be supported by plastic.

[0042] The first rotating support 300 can rotate along the first surface.

[0043] The first phase-shifting conductor strip 400 is located on the side of the first rotating support 300 facing the first surface and is connected to the first rotating support 300.

[0044] The first phase-shifting conductor strip 400 can be fixedly connected to or detachably connected to the first rotating support 300. For example, the first phase-shifting conductor strip 400 can be bonded to the first rotating support 300 through an adhesive layer.

[0045] The first phase-shifting conductor strip 400 can be made of a conductive material.

[0046] The first phase-shifting conductor strip 400 is located on the side of the first rotating support 300 facing the first surface and is connected to the first rotating support 300. The vertical projection of the first phase-shifting conductor strip 400 on the first carrier plate 100 partially overlaps with the vertical projection of the first conductor strip 210 on the first carrier plate 100, and the first phase-shifting conductor strip 400 and the first conductor strip 210 are coupled together. The overlapping portion of the first phase-shifting conductor strip 400 and the first conductor strip 210 in the second direction F2 is also coupled together.

[0047] The vertical projection of the first phase-shifting conductor strip 400 on the first carrier plate 100 partially overlaps with the vertical projection of the second conductor strip 220 on the first carrier plate 100, and the first phase-shifting conductor strip 400 and the second conductor strip 220 are coupled together. Specifically, the overlapping portion of the first phase-shifting conductor strip 400 and the second conductor strip 220 in the second direction F2 is coupled together.

[0048] Therefore, the first signal coupling end of the first conductor strip 210 can be used to receive signals, and the signals can be coupled from the first conductor strip 210 to the first phase-shifting conductor strip 400, and then coupled from the first phase-shifting conductor strip 400 to the second conductor strip 220, or the signals can be coupled from the second conductor strip 220 to the first phase-shifting conductor strip 400, and then coupled from the first phase-shifting conductor strip 400 to the first conductor strip 210, and then radiated from the first conductor strip 210.

[0049] When the first rotating support 300 drives the first phase-shifting conductor strip 400 to rotate, the vertical projection of the first phase-shifting conductor strip 400 on the first carrier plate 100 coincides with the different positions of the vertical projection of the second conductor strip 220 on the first carrier plate 100, so that the first phase-shifting conductor strip 400 and the second conductor strip 220 are coupled and connected at different positions, thereby changing the signal transmission path between the first signal coupling end and the second signal coupling end.

[0050] When the first rotating support 300 rotates, the first phase-shifting conductor strip 400 moves accordingly, so that the vertical projection of the first phase-shifting conductor strip 400 on the first surface can cover different positions of the second conductor strip 220. In this way, the first phase-shifting conductor strip 400 can contact and couple with different positions of the second conductor strip 220, thereby changing the transmission distance of the signal on the second conductor strip 220 and thus changing the phase of the signal.

[0051] In the phase shifter 1000 provided in this disclosure, since the first conductor strip 210 and the second conductor strip 220 are independent of the structure of the first carrier plate 100, in the event of a problem with the first conductor strip 210 and the second conductor strip 220, the first conductor strip 210 and the second conductor strip 220 can be repaired or replaced separately, thereby facilitating the repair of the first conductor strip 210 and the second conductor strip 220.

[0052] In addition, the first conductor strip 210 and the second conductor strip 220 were not formed using PCB etching process, which can reduce contamination.

[0055] For example, the number of first connecting parts 212 can be one or more.

[0056] The second conductor strip 220 includes a second strip body 221 and a second connecting part 222, the second connecting part 222 being connected to the second strip body 221.

[0057] For example, the second strip body 221 may be strip-shaped, and the extension trajectory of the second strip body 221 may be arc-shaped. The second strip body 221 may include a second side, and the second connecting part 222 may connect to the second side of the second strip body 221.

[0058] In some examples, the second strip body 221 may include a serpentine routing section. By providing the serpentine routing section, the length of the second strip body 221 can be increased, thereby improving the phase adjustment range of the second strip body 221.

[0059] For example, the number of second connecting parts 222 can be one or more.

[0067] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the first connector 510 includes a first adhesive layer that adheres between the first connector 212 and the first carrier plate 100.

[0068] For example, the first adhesive layer can be hot melt adhesive. The first connecting part 212 of the first wire body 211 and the first carrier plate 100 are connected through the first adhesive layer. The method is simple and the cost is low.

[0069] The second connector 520 includes a second adhesive layer, which is adhered between the second connector 222 and the first carrier plate 100.

[0070] For example, the second adhesive layer can be hot melt adhesive. The second adhesive layer is used to connect the second connecting part 222 of the second wire body 221 and the first carrier plate 100. This method is simple and low in cost.

A first insulating layer and a third insulating layer are provided between the first sheet metal strip section and the third sheet metal strip section. The thickness of the first insulating layer and the thickness of the third insulating layer are relatively small, and the first sheet metal strip section and the third sheet metal strip section can be coupled and connected.

[0105] By adjusting the position of the first phase-shifting conductor strip 400, the distance the signal travels from the first conductor strip 210 to the first end 223 can be changed, thereby changing the phase of the signal.

[0106] The phase shifter 1000 may further include a first grounding conductor strip 230, wherein the first grounding conductor strip 230 is disposed on a first surface and is spaced apart from the first conductor strip 210 and the second conductor strip 220.

[0111] Furthermore, by providing a first opening in the second insulation layer, it is convenient to connect the first end 223 to the coaxial cable.

[0115] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the phase shifter 1000 may further include a first cable management component 800. The first cable management component 800 is disposed on the first carrier plate 100, and a first cable management groove 801 is provided on the first cable management component 800 for accommodating the first coaxial cable.

[0116] The first cable management component 800 and the first cable management groove 801 can fix the first coaxial cable and facilitate the organization of the first coaxial cable.

[0117] In some examples, there are two first cable management components 800, which are respectively disposed at both ends of the first carrier plate 100 in the third direction F3. The first conductor strip 210, the second conductor strip 220, the first rotating support 300 and the first phase-shifting conductor strip 400 can be disposed between the two first cable management components 800.

[0118] The first conductor strip 210, the second conductor strip 220, the first rotating support 300, and the first phase-shifting conductor strip 400 can form the first power supply module.

[0119] Please see Figure 2 , Figure 3 and Figure 4 In some embodiments, the phase shifter 1000 may further include: a zero-point substrate 600, a second carrier 710, and a second power supply module. The second power supply module may include: a third conductor strip 720, a fourth conductor strip 730, and a second phase-shifting conductor strip 750. The third conductor strip 720 includes a third signal coupling terminal, and the fourth conductor strip 730 includes a fourth signal coupling terminal.

[0120] The zero-point substrate 600 is located on the side of the first carrier plate 100 that is away from the first surface.

[0121] The zero-point substrate 600 is used to provide a zero-point potential. For example, the zero-point substrate 600 may include a metal plate.

[0122] For example, the zero-point substrate 600 can be bonded to the first carrier plate 100 by an adhesive layer.

[0123] The second carrier plate 710 is located on the side of the zero-point substrate 600 away from the first carrier plate 100, and the second carrier plate includes a second surface facing the zero-point substrate 600.

[0124] For example, the second carrier plate 710 can be bonded to the zero-point substrate 600.

[0125] The third conductor strip 720 and the fourth conductor strip 730 are disposed at intervals on the second surface.

[0126] The second rotating support 740 is disposed on the second surface and is rotatably connected to the second carrier plate 710.

[0127] The second phase-shifting conductor strip 750 is located on the side of the second rotating support 740 facing the second surface and is connected to the second rotating support 740. The vertical projection of the second phase-shifting conductor strip 750 on the second carrier plate 710 partially overlaps with the vertical projection of the third conductor strip 720 on the second carrier plate 710, and the second phase-shifting conductor strip 750 is coupled to the third conductor strip 720. The vertical projection of the second phase-shifting conductor strip 750 on the second carrier plate 710 partially overlaps with the vertical projection of the fourth conductor strip 730 on the second carrier plate 710, and the second phase-shifting conductor strip 750 is coupled to the fourth conductor strip 730.

[0128] When the second rotating support 740 drives the second phase-shifting conductor strip 750 to rotate, the vertical projection of the second phase-shifting conductor strip 750 on the second carrier plate 710 coincides with the different positions of the vertical projection of the second conductor strip 220 on the second carrier plate 710, so that the second phase-shifting conductor strip 750 and the second conductor strip 220 are coupled and connected at different positions, thereby changing the signal transmission path between the third signal coupling end and the fourth signal coupling end.

[0129] One of the first and second feeding modules can be used as the positive feeding module, and the other can be used as the negative feeding module.

[0130] The structure of the second power supply module is the same as that of the first power supply module, which facilitates assembly. Furthermore, in the event of a failure in either the first or second power supply module, the first carrier board 100 and the second carrier board 710 can be separated to repair the faulty power supply module individually, thereby improving the flexibility of the installation process.

[0131] Please see Figure 2 , Figure 3 and Figure 4In some embodiments, the first cable management component 800 may also be disposed on the second carrier plate 710. The first cable management groove 801 of the first cable management component 800 on the second carrier plate 710 can fix the second coaxial cable and facilitate the organization of the second coaxial cable.

[0132] In some embodiments, the phase shifter 1000 may further include a snap-fit ​​member 900 disposed on one side of the first cable management member 800 in the first direction F1.

[0133] For example, a first cable management component 800 has snap-fit ​​components 900 on both sides in the first direction F1.

[0134] The snap-fit ​​component 900 includes a snap-fit ​​portion 910 and a fastening portion 940. The snap-fit ​​portion 910 includes a fixing portion 930 and a snap-fit ​​protrusion 920. The fixing portion 930 is connected to one side of the first cable management component 800 in the first direction F1, and the snap-fit ​​protrusion 920 is disposed on the side of the fixing portion 930 away from the first cable management component 800.

[0135] The fastening part 940 is connected to one side of the first cable management component 800 in the first direction F1, and the fastening part 940 is provided with a snap-fit ​​opening 941.

[0136] The snap-fit ​​opening 941 of the snap-fit ​​portion 940 of the snap-fit ​​member 900 provided on the first cable management member 800 on the first carrier plate 100 can snap with the snap-fit ​​protrusion 920 of the snap-fit ​​portion 910 of the snap-fit ​​member 900 provided on the first cable management member 800 of the second carrier plate 710, thereby fixing the first carrier plate 100 and the second carrier plate 710, thereby improving the reliability of the connection between the first carrier plate 100 and the second carrier plate 710.

[0138] Please see Figure 5 and Figure 6 In other embodiments, the first carrier plate 100 further includes a third surface disposed opposite to the first surface, and the first carrier plate 100 further includes a receiving cavity disposed between the first surface and the second surface.

[0139] The first carrier plate 100 is also provided with a cavity, which is located on the side of the first carrier plate 100 and is connected to the receiving cavity.

[0140] The phase shifter 1000 also includes a zero-point substrate 600, which is located within the receiving cavity.

[0141] The third conductor strip 720 and the fourth conductor strip 730 are spaced apart on the third surface. The third conductor strip 720 includes a third signal coupling terminal, and the fourth conductor strip 730 includes a fourth signal coupling terminal.

[0142] The second rotating support 740 is disposed on the third surface and is rotatably connected to the second carrier plate 710.

[0143] The second phase-shifting conductor strip 750 is located on the side of the second rotating support 740 facing the third surface and is connected to the second rotating support 740. The vertical projection of the second phase-shifting conductor strip 750 on the first carrier plate 100 partially overlaps with the vertical projection of the third conductor strip 720 on the first carrier plate 100, and the second phase-shifting conductor strip 750 is coupled to the third conductor strip 720. The vertical projection of the second phase-shifting conductor strip 750 on the first carrier plate 100 partially overlaps with the vertical projection of the fourth conductor strip 730 on the first carrier plate 100, and the second phase-shifting conductor strip 750 is coupled to the fourth conductor strip 730.

[0144] When the second rotating support 740 drives the second phase-shifting conductor strip 750 to rotate, the vertical projection of the second phase-shifting conductor strip 750 on the first carrier plate 100 coincides with the different positions of the vertical projection of the second conductor strip 220 on the first carrier plate 100, so that the second phase-shifting conductor strip 750 and the second conductor strip 220 are coupled and connected at different positions, thereby changing the signal transmission path between the third signal coupling end and the fourth signal coupling end.

[0145] In this embodiment, the second feed module and the first feed module can be respectively disposed on two opposite surfaces of the first carrier plate 100. Therefore, the second feed module and the first feed module can share a first carrier plate 100, thereby effectively saving space, which can reduce the thickness of the phase shifter 1000 and has high space utilization in the height direction, which is advantageous in complex antenna internal layout.
