Description

Technical Field

[0001] This invention relates to the field of communication equipment technology, and in particular to a phase shifting device and an antenna. Background Technology

[0002] With the development of base station antenna technology, antennas are evolving towards multi-frequency, compact, and efficient designs, placing increasingly stringent requirements on control precision and size. As a key component for antenna downtilt adjustment, the phase shifter faces even higher demands on its transmission precision.

[0003] Currently, most phase shifter sliding devices use a transmission method that first converts the rotation of the motor into the horizontal sliding of the pull rod, and then converts the horizontal sliding of the pull rod into the curvilinear motion of the PCB slider. This structure has the following disadvantages: each conversion between rotation and sliding results in a loss of transmission efficiency; the threads cannot be perfectly matched, inevitably resulting in gaps; and there is a backlash, leading to large cumulative errors and reduced transmission accuracy. Furthermore, the multiple motion conversions between the phase shifter sliding device and the motor drive inevitably result in many parts and a complex structure, making assembly cumbersome and unable to meet the requirements of small sizes. Summary of the Invention

[0004] This invention provides a phase shifting device and antenna to solve the problems of low transmission accuracy, numerous parts, and cumbersome assembly in most existing phase shifter sliding devices.

There is a height difference between the plane where the horizontal portion is located and the plane where the turntable body is located, so that the receiving space can be formed between the turntable body and the phase shifting substrate.

[0011] According to a phase shifting device provided by the present invention, the turntable body, the connecting part, and the horizontal part are integrally formed.

[0012] According to a phase shifting device provided by the present invention, the turntable includes a turntable body and a mounting portion.

[0013] According to a phase shifting device provided by the present invention, the mounting portion includes a transition portion and a horizontal portion.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] like Figures 1 to 4 As shown, the phase shifting device of this embodiment includes: a turntable 1, a phase shifting substrate 2, and a driving component 3.

[0032] Both the turntable 1 and the phase-shifting substrate 2 are insulating dielectric substrates. The turntable 1 is rotatably mounted on the phase-shifting substrate 2. For example, the turntable 1 is rotatably mounted on the phase-shifting substrate 2 via a rotating shaft, or the turntable 1 is rotatably mounted on the phase-shifting substrate 2 via a guide rail. The phase-shifting substrate 2 is provided with an arc-shaped feed line 21, and the turntable 1 is provided with a coupling line 12211. The arc-shaped feed line 21 and the coupling line 12211 are intersecting. For example, the arc-shaped feed line 21 extends along the circumferential direction of the turntable 1, while the coupling line 12211 extends along the radial direction of the turntable 1.

[0033] Specifically, one or more main PCBs can be mounted on the phase-shifting substrate 2, and the arc-shaped feed line 21 can be mounted on the main PCB in the form of a microstrip line. One or more sub-PCBs can be mounted on the turntable 1, and the coupling line 12211 can be mounted on the sub-PCB in the form of a microstrip line. It should be noted that when the structure of the turntable 1 and the phase-shifting substrate 2 is relatively simple, the turntable 1 and the phase-shifting substrate 2 can also be directly made into a PCB as a whole and the corresponding microstrip lines can be etched on it.

[0034] It should be noted that when the turntable 1 is in contact with or close to the phase-shifting substrate 2, coupling can occur between the relatively arranged arc-shaped feed line 21 and the coupling line 12211. Furthermore, as the turntable 1 rotates relative to the phase-shifting substrate 2, the distance between the main feed port of the main feed line and the feed port of the arc-shaped feed line 21 changes, thereby producing a phase change effect and realizing phase shifting operation, which can achieve adjustment of the antenna's electrical downtilt angle.

[0035] The shapes of the turntable 1 and the phase-shifting substrate 2 are varied, but the shape of the turntable 1 should be adapted to the shape of the phase-shifting substrate 2 in order to improve the integration of the phase-shifting device.

[0036] For example, the phase-shifting substrate 2 can be an annular PCB board with multiple microstrip arc-shaped feed lines 21 evenly spaced along its radial direction. The arc-shaped feed lines 21 are concentric with the phase-shifting substrate 2, and each output terminal of the arc-shaped feed line 21 is connected to a radiating unit. The turntable 1 is an annular PCB board with an outer circumference approximately the same as that of the phase-shifting substrate 2, and is located directly above the phase-shifting substrate 2. The center of the turntable 1 is on the same straight line as the center of the phase-shifting substrate 2. The surface of the turntable 1 is provided with a microstrip coupling line 12211 that can couple with the arc-shaped feed lines 21, and the extension line of the extension path of the coupling line 12211 passes through its center. Further, the driving component 3 is connected to the turntable 1 in a transmission manner. Under the drive of the driving component 3, the turntable 1 can rotate relative to the phase-shifting substrate 2, so that the coupling line 12211 can move along the arc-shaped feed line 21, thereby changing the distance between the main feed port of the main feed line and the feed port of the arc-shaped feed line 21.

[0037] In this embodiment of the invention, the turntable 1 can rotate relative to the fixedly mounted phase-shifting substrate 2 under the drive of the driving component 3. As the turntable 1 and the phase-shifting substrate 2 move relative to each other, the distance between the main feed port of the main feed line and the feed port of the arc-shaped feed line 21 changes, thereby achieving phase adjustment. Compared with the phase shifter sliding device in the prior art, the transmission efficiency is improved to a certain extent, and the accuracy is high, which can improve the accuracy of the electrical indicators of the base station antenna.

[0038] In optional embodiments, such as Figure 1 and Figure 2As shown, one of the inner and outer circumferences of the turntable 1 is provided with teeth 111. The drive assembly 3 includes a drive motor 31 and an output gear 32. The drive motor 31 and the output gear 32 are connected in a transmission manner, and the output gear 32 is meshed with the teeth 111.

[0039] Specifically, the turntable 1 and the phase-shifting substrate 2 can be annular components with approximately equal shaft diameters. The turntable 1 is coaxially positioned above the phase-shifting substrate 2. To ensure that the turntable 1 remains directly above the phase-shifting substrate 2 during rotation and that the coupling line 12211 is always coupled to the corresponding arc-shaped feed line 21, the phase-shifting substrate 2 is provided with a guide portion, and correspondingly, the turntable 1 is provided with a sliding body.

[0040] For example, when the toothed portion 111 is provided on the inner periphery of the turntable 1, the outer periphery of the phase-shifting substrate 2 is provided with an annular groove as a guide portion. Correspondingly, the outer periphery of the turntable 1 is provided with a sliding portion 1222 that is adapted to the annular groove. The sliding portion 1222 can be engaged in the annular groove and slide along the annular groove. Alternatively, when the toothed portion 111 is provided on the outer periphery of the turntable 1, the inner periphery of the phase-shifting substrate 2 is provided with an annular groove as a guide portion along the rotation direction. The corresponding position of the turntable 1 is provided with a slider that is adapted to the annular groove. The slider can slide and engage with the annular groove.

[0041] It is understandable that placing the toothed portion 111 on the inner periphery of the turntable 1 makes the structure of the phase shifting device more compact; while placing the toothed portion 111 on the outer periphery of the turntable 1 allows the turntable 1 and the phase shifting substrate 2 to obtain a larger area for arranging the corresponding arc-shaped feed line 21 and coupling line 12211.

[0042] In this embodiment of the invention, when the output shaft of the drive motor 31 rotates, the output gear 32 rotates accordingly, and the output gear 32 drives the turntable 1 to rotate synchronously. The turntable 1 rotates relative to the phase-shifting substrate 2. Therefore, the coupling position between the coupling line 12211 on the turntable 1 and the arc-shaped feed line 21 on the phase-shifting substrate 2 changes, thereby realizing phase shifting.

[0043] It is particularly noteworthy that the output gear 32 not only provides a deceleration and vibration damping effect but also increases the phase shifting accuracy of the phase shifter. Each rotation of the output gear 32 by one tooth results in a change of one unit in the coupling line length between the coupling line 12211 and the arc-shaped feed line 21. The amount of phase shift in the phase shifting device can be controlled by the number of teeth rotated by the output gear 32. Furthermore, increasing the tooth profile density of the output gear 32 and the teeth 111 can improve the accuracy of the phase shifting device.

[0044] In optional embodiments, such as Figure 1As shown, the turntable 1 includes a turntable body 11 and a mounting part 12. The inner circumference of the turntable body 11 is provided with teeth 111. The outer circumference of the turntable body 11 extends in a direction away from the center of the turntable body 11 to form the mounting part 12. The mounting part 12 is provided with a mounting position 1221 and a coupling line 12211 is provided in the mounting position 1221.

[0045] For example, the turntable body 11 may be an annular structure, and the mounting portion 12 is uniformly disposed on the outer periphery of the turntable body 11 along the circumferential direction. The turntable body 11 and the mounting portion 12 are integrally formed.

[0046] It should be noted that the mounting position 1221 can be a recess, and a secondary PCB board with coupling lines 12211 on its surface is located in the recess. The secondary PCB board is detachably connected to the mounting position 1221, which facilitates the replacement and maintenance of the circuit board in the future.

[0047] Furthermore, a sliding part 1222 may be provided at the end of the mounting part 12 away from the turntable body 11. The sliding part 1222 can be engaged in the annular groove of the phase shifting substrate 2 and slide along the annular groove. The provision of the sliding part 1222 enables the turntable 1 and the phase shifting substrate 2 to rotate in the same circle, thereby ensuring that the coupling line 12211 is always coupled with the corresponding arc-shaped feed line 21, improving the coupling accuracy.

[0048] The turntable body 11 and the phase-shifting substrate 2 can form a receiving space 13, and the drive component 3 can be partially disposed within the receiving space 13. For example, the output gear 32 is arranged on the same plane as the turntable body 11, and the drive motor 31 can be disposed within the receiving space 13. Furthermore, if the phase-shifting substrate 2 is a ring-shaped PCB board, the bottom of the drive motor 31 can extend outside the receiving space 13 to facilitate the installation of the drive motor 31.

[0049] In optional embodiments, such as Figures 1 to 3 As shown, the mounting portion 12 includes a connecting portion 121 and a horizontal portion 122. The connecting portion 121 is formed by bending and extending the outer periphery of the turntable body 11. The horizontal portion 122 is formed by extending the connecting portion 121 in a direction away from the center of the turntable body 11. The horizontal portion 122 is provided with a mounting position 1221. There is a height difference between the plane where the horizontal portion 122 is located and the plane where the turntable body 11 is located, so that a receiving space 13 can be formed between the turntable body 11 and the phase shifting substrate 2. The end of the horizontal portion 122 away from the connecting portion 121 may be provided with a sliding portion 1222.

[0050] Overall, the turntable body 11 is arranged parallel to the horizontal portion 122, and the horizontal height of the turntable body 11 is higher than that of the horizontal portion 122. The upper end of the adapter portion 121 is connected to the outer periphery of the turntable body 11 at an angle, and the lower end of the adapter portion 121 is connected to one end of the horizontal portion 122 at an angle. For example, both ends of the adapter portion 121 are respectively arranged perpendicular to the turntable body 11 and the horizontal portion 122.

[0051] Understandably, as the height of the adapter 121 increases, the accommodating space 13 between the turntable body 11 and the phase-shifting substrate 2 correspondingly increases. The accommodating space 13 is used to house the drive assembly 3; in other words, the height of the adapter 121 can be determined according to the height of the drive motor 31. For example, the bottom end of the drive motor 31 is on the same plane as the phase-shifting substrate 2, and the top surface of the output gear 32 is on the same plane as the top of the turntable body 11, thereby improving the compactness of the phase-shifting device.

[0052] In optional embodiments, such as Figure 3 As shown, the turntable body 11, the adapter 121 and the horizontal part 122 are integrally formed.

[0053] It should be noted that since the turntable body 11, the connecting part 121 and the horizontal part 122 are integrally formed, assembly tolerances can be avoided among the turntable body 11, the connecting part 121 and the horizontal part 122. This ensures that the rotation of each tooth of the tooth 111 of the turntable body 11 corresponds to an accurate change in the coupled phase, thereby guaranteeing the phase shifting accuracy of the phase shifting device.

[0054] In optional embodiments, such as Figure 2 As shown, the turntable 1 includes a turntable body 11 and a mounting part 12. The outer periphery of the turntable body 11 is provided with teeth 111. The inner periphery of the turntable body 11 extends toward the center of the turntable body 11 to form the mounting part 12. The mounting part 12 is provided with a mounting position 1221 and a coupling line 12211 is provided in the mounting position 1221.

[0055] Specifically, the turntable body 11 may be a ring-shaped structure with teeth 111 on its outer periphery for meshing with the output gear 32. The mounting part 12 has a mounting position 1221 near the turntable body 11, and the coupling line 12211 is located at the mounting position.

[0056] In addition, a pivot hole is provided at the center of the mounting part 12, and a pivot that can slide relative to the pivot hole is protruded at the corresponding position of the phase shifting substrate 2, so as to ensure that the center position of the turntable 1 remains unchanged when it rotates relative to the phase shifting substrate 2.

[0057] It is understandable that a gap is formed between the turntable body 11 and the phase shifting substrate 2 to facilitate the installation of the drive motor 31, so that the output gear 32 can mesh with the tooth 111, and the output gear 32 will not collide with the phase shifting substrate 2 when it rotates, thereby improving the safety of the structure.

[0058] In optional embodiments, such as Figure 2 As shown, the mounting portion 12 includes a transition portion 121 and a horizontal portion 122. The transition portion 121 is formed by bending and extending the inner periphery of the turntable body 11. The horizontal portion 122 is formed by extending the transition portion 121 toward the center of the turntable body 11. The horizontal portion 122 is provided with a mounting position 1221. There is a height difference between the plane where the horizontal portion 122 is located and the plane where the turntable body 11 is located, so that a gap can be formed between the turntable body 11 and the phase shifting substrate 2.

[0059] It should be noted that the horizontal section 122 includes a first part and a second part. The first part is strip-shaped and evenly distributed along the inner circumference of the turntable body 11, while the second part is ring-shaped. That is, multiple first parts converge at the second part. The mounting position 1221 is located in the first part. The center of the turntable body 11 and the center of the second part are on the same straight line.

[0060] Overall, the turntable body 11 is arranged parallel to the horizontal portion 122, and the horizontal height of the turntable body 11 is higher than that of the horizontal portion 122. One end of the connecting portion 121 is set at an angle to the outer periphery of the turntable body 11, and the other end is set at an angle to the end of the horizontal portion 122. For example, both ends of the connecting portion 121 are respectively set perpendicular to the turntable body 11 and the horizontal portion 122.

[0061] It is understandable that the adapter 121 can adjust the height of the turntable body 11. As the height of the adapter 121 increases, the gap between the turntable body 11 and the phase shifting substrate 2 increases.

[0062] In optional embodiments, such as Figure 4 As shown, there are multiple arc-shaped feeder lines 21 arranged in a circle; there are multiple coupling lines 12211, and each coupling line corresponds to one of the multiple arc-shaped feeder lines 21.

[0063] For example, there are four arc-shaped feed lines 21, which are evenly distributed along the circumferential direction of the phase-shifting substrate 2. Each arc-shaped feed line 21 may include three arc-shaped microstrip lines, which are evenly distributed along the radial direction of the phase-shifting substrate 2, and each arc-shaped microstrip line is concentric with the phase-shifting substrate 2. This ensures that when the turntable 1 rotates relative to the phase-shifting substrate 2, the coupling line 12211 on it is always coupled with the corresponding arc-shaped microstrip line. The six output terminals formed by the three arc-shaped microstrip lines are respectively connected to different radiating elements of the antenna.

[0064] Furthermore, as the radius of the arc-shaped microstrip line decreases, the power of the antenna radiating element connected to the output end of the arc-shaped microstrip line increases, thus forming a set of six-element low-gain electrically tunable antennas. Correspondingly, four mounting sections 12 are provided on the turntable 1, each mounting section 12 having a coupling line 12211 coupled to each corresponding arc-shaped feed line 21. When there are four arc-shaped feed lines 21, four sets of electrically tunable antennas can be formed.

[0065] Furthermore, the drive motor 31 drives the output gear 32 to rotate at a certain angle, and the output gear 32 drives the tooth section 111 to rotate at a certain number of teeth, causing the turntable 1 to rotate at a certain angle relative to the phase shifting device. When a phase shifting device is equipped with four arc-shaped feed lines 21 and four coupling lines 12211, as the turntable 1 rotates, the four coupling lines 12211 can achieve a change in coupling phase with the corresponding arc-shaped feed lines 21, thereby enabling a phase shifting device to adjust four electrically adjustable antennas simultaneously.

[0066] In optional embodiments, such as Figure 4 As shown, the phase-shifting substrate 2 is also provided with an arc-shaped main feed line 22. When the turntable 1 rotates relative to the phase-shifting substrate 2, the coupling line 12211 can move along the arc-shaped main feed line 22 and be coupled to the arc-shaped main feed line 22.

[0067] Specifically, both the arc-shaped main feed line 22 and the arc-shaped feed line 21 are disposed on the phase-shifting substrate 2. Multiple arc-shaped microstrip lines of both the arc-shaped main feed line 22 and the arc-shaped feed line 21 are arranged concentrically, with the arc-shaped main feed line 22 positioned closer to the center of the phase-shifting substrate 2. The feed port of the arc-shaped main feed line 22 serves as an input terminal connected to the radio frequency unit, while multiple ports of the arc-shaped feed line 21 serve as output terminals connected to different radiating elements of the antenna. The coupling line 12211 can couple to the corresponding arc-shaped main feed line 22 and arc-shaped feed line 21 respectively.

[0068] Furthermore, embodiments of the present invention also provide an antenna including the phase-shifting device described above.

[0069] Specifically, since the antenna includes the phase-shifting device as described above, and the specific structure of the phase-shifting device is as described in the above embodiments, the antenna shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the above technical solutions, which will not be described in detail here.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
