Description

Technical Field

[0001] This invention relates to the field of antenna technology, and in particular to a feed network device and its adjustment method that are independently adjustable in amplitude and phase. Background Technology

[0002] As mobile communication technology evolves towards 5G-Advanced and 6G, base station antennas need to possess precise beamforming capabilities. The core of this capability lies in the precise and independent control of the amplitude and phase of the excitation signals for each radiating element in the array. The feed network, as a key component in achieving this function, directly affects parameters such as the antenna array's gain, beam pointing, and sidelobe level.

[0003] However, existing power supply network technologies still have shortcomings in achieving independent and flexible control of amplitude and phase.

[0004] 1) Passive networks lack flexibility. Traditional passive power supply networks, which consist of power dividers, fixed phase shifters, etc., have their amplitude and phase distributions determined during the design phase, making them unable to adapt to dynamically changing network requirements.

[0005] 2) The cost of all-digital solutions is too high. Although digital beamforming technology can achieve flexible amplitude and phase control, it requires an independent radio frequency channel for each radiating element, which significantly increases system complexity, cost and power consumption, making it difficult to widely use in passive base station antennas.

[0006] 3) Limited control capability of hybrid schemes: Improved schemes that introduce adjustable elements can usually only perform coarse phase adjustment or static compensation, which is difficult to meet the requirements of high-order beamforming for wide range, high precision and real-time independent adjustment of amplitude and phase.

[0007] Therefore, there is a need in the field for a new type of feed network device that can achieve independent and continuous adjustment of amplitude and phase, and that adjusting either amplitude or phase does not affect the other parameter or the overall impedance matching of the network. It should also be compact, easy to integrate, and easy to control, so as to meet the growing demand of modern communication systems for high-performance and miniaturized antennas. Summary of the Invention

[0008] To address the aforementioned issues, this application provides a power supply network device and its adjustment method with a reasonable structure and independently adjustable amplitude and phase, thereby overcoming the shortcomings of existing power supply networks, such as the mutual coupling of amplitude and phase adjustment, complex adjustable network design, and low integration of phase shifting components.

[0009] The technical solution adopted in this invention is as follows: An amplitude and phase independently adjustable power supply network device includes an amplitude adjustment unit and a phase adjustment unit. The amplitude adjustment unit includes a main feed line, an amplitude adjustment line, a rotating component, and a coupler. The main feed line is electrically connected to the amplitude adjustment line via the rotating component, and the two output terminals of the amplitude adjustment line are connected to the corresponding input terminals of the coupler. The phase adjustment unit includes a phase adjustment line, a translation component, and an output line. One end of the phase adjustment line is connected to the output terminal of the coupler, and the other end of the phase adjustment line is electrically connected to the output line via the translation component.

[0010] As a further improvement to the above technical solution: The rotating component includes a rotating part and a coupling plate 1 disposed on the rotating part. A pivot hole connected to the coupling plate 1 is provided on the main feed line. The amplitude adjustment line includes an arc-shaped line with the pivot hole as the center. The coupling plate 1 rotates with the rotating part with the pivot hole as the center. The arc-shaped part of the coupling plate 1 is connected to the arc-shaped line.

[0011] The rotating component is provided with a shaft, a drive unit, and a mounting guide unit. The shaft and the pivot hole are aligned and form a mechanical rotation structure. The drive unit is connected to an external driving power source to drive the rotating component to rotate around the shaft. The mounting guide unit is installed with an external object to limit the rotation range of the rotating component.

[0012] The shaft is located in the middle of the rotating part, and the drive part and the mounting guide part are located at both ends of the rotating part; the external object is a base plate, and an arc-shaped groove is provided on the base plate for the mounting guide part to be mounted and move relative to each other. The arc-shaped groove and the arc-shaped line are arranged concentrically.

[0013] The amplitude adjustment circuit also includes a connecting line one that connects to both ends of the arc-shaped circuit, and the connecting line one connects the arc-shaped circuit to the input end of the coupler.

[0014] The phase adjustment line and the output line are arranged independently and are provided with parallel lines that are parallel to each other. The translation component includes a translation component and a second coupling plate. The second coupling plate moves along the length of the parallel line with the translation component and connects the phase adjustment line and the output line at the parallel line.

[0015] The phase adjustment circuit also includes a connecting line two that connects the parallel line and the output of the coupler.

[0016] The phase adjustment unit includes two sets of phase shifting components. Each set of phase shifting components includes a phase adjustment line and an output line. The phase adjustment line of each set of phase shifting components is connected to the corresponding output terminal of the coupler. The two sets of phase shifting components share the same set of translation components.

[0017] It also includes a substrate, on which the amplitude adjustment unit and the phase adjustment unit are coplanarly arranged; or, the amplitude adjustment unit and the phase adjustment unit are arranged in layers and interconnected by metallized vias.

[0018] A method for adjusting the amplitude and phase of a power supply network device includes independent amplitude adjustment methods and phase adjustment methods. The amplitude adjustment method includes: the main feed line is formed into two signals with a phase difference through a rotating component and an amplitude adjustment line, and these signals are respectively input to the two input terminals of a coupler. The two signals are vector-combined in the coupler and then output to the phase adjustment unit. The phase difference between the two signals is adjusted by the continuous rotation of the rotating component, thereby realizing continuous adjustment of the signal amplitude. The phase adjustment method includes: the phase adjustment line receives the signal output from the coupler, and changes the actual transmission path length between the phase adjustment line and the output cable by the continuous translation of the translation component, thereby realizing continuous adjustment of the signal phase.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses an amplitude adjustment unit for amplitude adjustment and a phase adjustment unit for phase adjustment, so that the amplitude and phase can be adjusted independently and continuously by different physical units. This greatly ensures the continuous and smooth change of the antenna beam pointing, helps to enhance the flexibility of beam control, and the device is simplified and highly integrated, effectively promoting the miniaturization of the whole. The present invention also includes the following advantages: The amplitude adjustment unit and the phase adjustment unit are cascaded in the signal path. Adjusting the amplitude does not change the phase characteristics of the signal, and adjusting the phase does not affect the impedance matching and amplitude distribution of the network. Furthermore, the overall structure is compact, simplified, and highly modular, avoiding the use of discrete components and complex cable connections.

[0020] By rotating the rotary component in the amplitude adjustment unit and translating the translation component in the phase adjustment unit, mechanical adjustments of rotation and translation are flexibly applied to the adjustment of amplitude and phase. The design is novel and ingenious, and has good practicality. Attached Figure Description

[0032] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, this embodiment of a power supply network device with independently adjustable amplitude and phase includes an amplitude adjustment unit 2 and a phase adjustment unit 3. The amplitude adjustment unit 2 includes a main feed line 21, an amplitude adjustment line 22, a rotating component 23, and a coupler 24. The main feed line 21 is electrically connected to the amplitude adjustment line 22 via the rotating component 23, and the two output terminals of the amplitude adjustment line 22 are connected to the corresponding input terminals of the coupler 24. The phase adjustment unit 3 includes a phase adjustment line 31, a translation component 33, and an output line 32. One end of the phase adjustment line 31 is connected to the output terminal of the coupler 24, and the other end of the phase adjustment line 31 is electrically connected to the output line 32 via the translation component 33.

[0034] In this embodiment, amplitude adjustment unit 2 performs amplitude adjustment and phase adjustment unit 3 performs phase adjustment, so that different physical units can independently adjust the amplitude and phase respectively, and their respective adjustments do not affect each other and can achieve continuous adjustment.

[0035] Amplitude adjustment unit 2 and phase adjustment unit 3 are cascaded in the signal path. Adjusting the amplitude does not change the phase characteristics of the signal, and adjusting the phase does not affect the impedance matching and amplitude distribution of the network. Furthermore, they are integrated in the same power supply network architecture in a modular form, resulting in a compact, simplified, and highly modular structure that avoids the use of discrete components and complex cable connections.

[0036] In this embodiment, the mechanical adjustment of rotation and translation is flexibly applied to the adjustment of amplitude and phase by rotating the rotation component 23 in the amplitude adjustment unit 2 and translating the translation component 33 in the phase adjustment unit 3. The design is novel and ingenious and has good practicality.

[0037] like Figure 3 As shown, the rotating component 23 includes a rotating member 231 and a coupling plate 232 disposed on the rotating member 231. The main feed line 21 is provided with a pivot hole 211 that connects to the coupling plate 232. The amplitude adjustment line 22 includes an arc-shaped line 221 with the pivot hole 211 as the center. The coupling plate 232 rotates with the rotating member 231 with the pivot hole 211 as the center. The arc-shaped part 2321 of the coupling plate 232 is connected to the arc-shaped line 221.

[0038] In this embodiment, by rotating the rotating member 231 around the pivot hole 211, the relative rotation angle between the arc-shaped line 221 and the main feed line 21 is changed by mechanical rotation, and the connection position between the arc-shaped part 2321 of the coupling piece 232 and the arc-shaped line 221 is changed, thereby realizing the phase difference between the two signals output from both ends of the amplitude adjustment line 22, and this change and adjustment is continuous.

[0039] In this embodiment, the pivot hole 211 not only serves as the physical axis for the rotating component 231 to be rotatably mounted and rotated, but also forms an electrical connection with the coupling piece 232.

[0040] In this embodiment, the coupler 24 can be a common type, such as a 3dB directional coupler, whose input end receives two signals with a specific phase difference from the amplitude adjustment line 22; the output signal amplitude of the coupler 24 is the vector synthesis result of the two input signals, and the output end generates output signals with different amplitudes; by adjusting the phase difference of the two signals output by the amplitude adjustment line 22, the signal amplitude can be continuously adjusted at the output end of the coupler 24.

[0041] The rotating component 231 is provided with a shaft 2310, a drive unit, and a mounting guide unit 2312. The shaft 2310 is aligned with the pivot hole 211 and forms a mechanical rotation structure. The drive unit is connected to an external driving power source to drive the rotating component 231 to rotate around the shaft 2310. The mounting guide unit is installed with an external object to limit the rotation range of the rotating component 231 and provide a guiding function for the rotation.

[0042] In this embodiment, the external driving force can be rotational force, which drives the rotating component 231 to rotate around the axis 2310.

[0043] Of course, in another embodiment, the external driving force can also be linear power. The driving part of the rotating member 231 has an elongated slot 2311. The elongated slot 2311 and the mounting guide part 2312 are arranged on both sides of the shaft 2310. The power end of the linear power is pivotally connected to the elongated slot 2311 of the rotating member 231. The linear motion of the linear power combined with the movement relative to the elongated slot 2311 drives the rotating member 231 to rotate about the shaft 2310.

[0044] The shaft 2310 is located in the middle of the rotating part 231, and the drive part and the mounting guide part 2312 are located at both ends of the rotating part 231. The external object is the substrate 1, and the substrate 1 has an arc-shaped groove 11 for mounting and relative movement of the mounting guide part 2312. The arc-shaped groove 11 and the arc-shaped line 221 are arranged concentrically.

[0045] In actual operation, the rotation of the rotating component 231 can be guided by the arc groove 11 and the mounting guide 2312 fitted in the arc groove 11, and the rotation range of the rotating component 231 can be limited by the arc groove 11, so that the rotating component 231 can rotate within a preset angle range.

[0046] In this embodiment, the mounting guide 2312 can be installed in the arc-shaped groove 11 using a snap-fit ​​structure, or other conventional structures can be used to meet the relative sliding guidance requirements.

[0047] The amplitude adjustment line 22 also includes a connecting line 222 connecting the two ends of the arc-shaped line 221, which connects the arc-shaped line 221 to the input end of the coupler 24.

[0048] In one embodiment, such as Figure 2 As shown, the main feed line 21 and coupler 24 are arranged in parallel at intervals, and the arc-shaped line 221 of the amplitude adjustment line 22 is arranged between them. The two ends of the arc-shaped line 221 are connected to the input ends of the coupler 24 via connecting line 222. The overall layout is compact.

[0049] The phase adjustment line 31 and the output line 32 are independently laid out and equipped with parallel lines 312 that are parallel to each other, such as... Figure 4 As shown, the translation component 33 includes a translation member 331 and a coupling plate 332. The coupling plate 332 moves along the length of the parallel line 312 with the translation member 331. The coupling plate 332 connects the phase adjustment line 31 and the output line 32 at the parallel line 312.

[0050] In this embodiment, the physical length of the actual line is changed by the movement of the translation member 331 along the length direction of the parallel line 312, thereby continuously changing the phase delay of the signal in the corresponding path.

[0051] In practice, the parallel lines 312 can be either straight or curved, and are laid out in parallel with each other.

[0052] In this embodiment, the translation component 331 can be driven to translate by an external power mechanism, such as a cylinder, hydraulic cylinder, electric cylinder, or other linear drive power to move along a straight parallel line 312.

[0053] In one embodiment, a mounting element 333 is also included, which causes the coupling piece 332 to adhere to the parallel line 312, ensuring effective electrical contact.

[0054] In this embodiment, the mounting component 333 is mounted onto the substrate 1 to achieve reliable installation relative to the substrate 1. The mounting component 333 is provided with a support arm facing the translation component 331. The support arm applies force to the translation component 331 so that the coupling piece 332 on it is attached to the parallel line 312.

[0055] In this embodiment, a guide groove 3311 can be formed on the translation member 331, and the mounting member 333 is provided with a guide arm that extends into the guide groove 3311. During the movement of the translation member 331, the guide arm and the guide groove 3311 provide movement guidance.

[0056] The phase adjustment line 31 also includes a connecting line 311 that connects the parallel line 312 to the output of the coupler 24, and the connecting line 311 connects the parallel line 312 in the phase adjustment line 31 to the output of the coupler 24.

[0057] The phase adjustment unit 3 includes two sets of phase shifting components. Each set of phase shifting components includes a phase adjustment line 31 and an output line 32. The phase adjustment line 31 of each set of phase shifting components is connected to the corresponding output terminal of the coupler 24, so that the two sets of phase shifting components can independently perform phase compensation adjustment on the two signals that have completed amplitude adjustment, so as to realize beam pointing control.

[0058] In the power supply network device of this embodiment, the signal transmission path is configured in the order of amplitude adjustment unit 2 first and phase adjustment unit 3 second.

[0059] Two sets of phase-shifting components share the same set of translation components 33 to achieve synchronous phase adjustment of the two signals.

[0060] In one embodiment, such as Figure 1 As shown, it also includes a substrate 1, such as a PTFE (polytetrafluoroethylene) dielectric substrate. The amplitude adjustment unit 2 and the phase adjustment unit 3 are coplanarly arranged on the substrate 1, adopting a fully coplanar form, so that all transmission lines are arranged on the same dielectric layer plane.

[0061] In another embodiment, the amplitude adjustment unit 2 and the phase adjustment unit 3 are arranged in layers and interconnected by metallized vias, which can also achieve independent adjustment of amplitude and phase. For example, transmission lines with different functions can be arranged in different dielectric layers.

[0062] In this embodiment, the main feed line 21, amplitude adjustment line 22, phase adjustment line 31, etc. in the power supply network device can be made using microstrip line or stripline planar transmission line technology, or other existing forms, as long as they can meet the requirements of signal transmission.

[0063] This embodiment also proposes a method for adjusting a feeder network device with independently adjustable amplitude and phase, including mutually independent amplitude adjustment methods and phase adjustment methods: The amplitude adjustment method includes: the main feed line 21 is formed into two signals with a phase difference through the rotating component 23 and the amplitude adjustment line 22, and respectively input to the two input terminals of the coupler 24. The two signals are vector synthesized in the coupler 24 and output to the phase adjustment unit 3. The phase difference between the two signals is adjusted by the continuous rotation of the rotating component 23, so as to realize the continuous adjustment of the signal amplitude.

[0064] The phase adjustment method includes: the phase adjustment line 31 receives the signal output from the coupler 24, and the actual transmission path length between the phase adjustment line 31 and the output line 32 is changed by the continuous translation of the translation component 33, so as to realize the continuous adjustment of the signal phase.

[0065] exist Figure 5 , Figure 6 , Figure 7 The illustrated embodiment demonstrates the adjustment process of amplitude adjustment unit 2. An RF signal is fed in from the input of the main feed line 21; a rotation angle is set by adjusting the rotating component 23, which determines the phase difference (denoted as ΔΦ) between the two input signals arriving at coupler 24; coupler 24 vector-combines these two signals with a phase difference ΔΦ, producing a specific amplitude distribution at its two output ports. For example, when in… Figure 5 In state a1, the signal amplitudes at both output ports are equal; when in state a1... Figure 6 In state a2, the average amplitude ratio of the two output port signals is 1:0.3; when in state a2... Figure 7 In state a3, the average amplitude ratio of the two output ports is 1:0.03; as ΔΦ changes continuously, the amplitude ratio of the two output ports changes continuously accordingly. This completes the independent setting of the signal amplitudes of the two output channels.

[0066] In this embodiment, the sum of the output signal power of the two channels is constant, but the ratio is adjustable.

[0067] exist Figure 8 , Figure 9 , Figure 10 The illustrated embodiment demonstrates the adjustment process of the phase adjustment unit 3. Two amplitude-adjusted signals output from coupler 24 enter two sets of phase-shifting components, respectively. By independently sliding the translation component 33, the transmission path lengths of the two channels are changed, thereby independently introducing the desired phase delay. For example, when the translation component 33 is in... Figure 8 In state b1, the average phase values ​​of the two output ports are θ+Δθ1 and θ-Δθ1, respectively. When the sliding translation component 33 is in... Figure 9 In state b2, the average phase values ​​of the two output ports are θ and θ, respectively. When the sliding translation component 33 is in Figure 10 In state b3, the average phase values ​​of the two output ports are θ-Δθ1 and θ+Δθ1, respectively. When the continuous sliding translation component 33 is used, the phase difference between the two output port signals changes continuously, thereby realizing continuous control of beam pointing.

[0068] Ultimately, the amplitude and phase of the signals obtained from the two output lines 32 of the device have been independently and continuously controlled.

[0069] This invention allows for independent and continuous adjustment of amplitude and phase by different physical units, which greatly ensures the continuous and smooth change of antenna beam pointing, helps to enhance the flexibility of beam control, and the device is simplified and highly integrated, effectively promoting the miniaturization of the whole.
