Description

Technical Field

[0001] This invention belongs to the field of antenna technology, and in particular relates to a beam-reconfigurable horn antenna device and its usage method. Background Technology

[0002] With the rapid development of radio frequency and microwave technology, the types of horn antennas are also increasing, and meeting testing and usage requirements more quickly has gradually become a key indicator for various systems. For conventional horn antennas, the aperture and depth dimensions of horn antennas with different frequency bands and gains are one of the core reasons for the wide variety, and all of them are fixed horn antennas.

[0003] Currently, traditional fixed horn antennas have a fixed size. Different sizes due to different frequency bands and gains require each one to be manufactured. Their fixed size means that different horn antennas need to be repeatedly disassembled and replaced during use. There are many types, and the cost of use is high, the cycle is long, and the use is cumbersome. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a beam-reconfigurable horn antenna device and its usage method. By extending and retracting a three-axis telescopic frame, the aperture size and depth can be adjusted in the X, Y, and Z directions, thus covering horn specifications with different gains across all frequency bands. Compared to the traditional method of manufacturing a separate horn antenna for each specification, this device achieves "one device for multiple frequencies and multiple gains," significantly reducing the number of spare parts and inventory volume. After setting the specified dimensions, the control system adjusts and corrects the actual dimensions based on feedback data from three distance feedback devices. Simply covering the three-axis telescopic frame with a metal covering layer is sufficient for testing a single horn antenna. This device allows for greater efficiency and can be widely used in the microwave testing field, offering greater convenience.

The first trapezoidal lead screw is threadedly connected to the telescopic motor. The end of the first trapezoidal lead screw away from the telescopic motor is movably connected to the four corners of the radiating aperture of the horn antenna. The end of the fixing rod away from the telescopic motor is movably connected to the waveguide module.

[0018] As a preferred embodiment of the present invention, the transverse electronically controlled telescopic component includes a hollow stepper motor, a second trapezoidal lead screw that rotates in both directions, two push rods, and two support rods. The two support rods are respectively disposed on both sides of the hollow stepper motor. The output end of the hollow stepper motor is coaxially connected to the second trapezoidal lead screw. The forward thread section and the reverse thread section of the second trapezoidal lead screw are respectively threaded with the two push rods. The push rods are slidably sleeved inside the support rods, and the push rods are provided with pins. The surface of the support rods is provided with pin guide grooves that slide with the pins.

[0019] The outer end of each push rod is hinged to the retaining rod sidewall of the corresponding depth-direction electrically controlled telescopic component, allowing the push rod to rotate around the Z-axis. The transverse electrically controlled telescopic component has the same structure as the longitudinal electrically controlled telescopic component.

[0042] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0043] In this embodiment, as shown in Figure 8, the X direction is the horizontal direction; the Y direction is the vertical direction; and the Z direction is the depth direction.

[0044] like Figure 1 - Figure 8 As shown, this embodiment proposes a beam-reconfigurable horn antenna device, including: a beam-coordinated module 1, which is relatively fixedly disposed at the rear end of the antenna device; a three-axis telescopic frame, connected to the front end of the beam-coordinated module 1, the three-axis telescopic frame being composed of at least a lateral electrically controlled telescopic component 2, a longitudinal electrically controlled telescopic component 3, and a depth-direction electrically controlled telescopic component 4, used to change the aperture and depth dimensions of the horn antenna; a distance feedback device 5, disposed at the aperture position of the three-axis telescopic frame, used to detect and feed back the actual aperture size to the control unit in real time; and a control unit, electrically connected to the lateral electrically controlled telescopic component 2, the longitudinal electrically controlled telescopic component 3, the depth-direction electrically controlled telescopic component 4, and the distance feedback device 5, used to control the telescopic movement of each electrically controlled telescopic component according to the target size, and to correct the actual size in a closed loop based on the feedback signal from the distance feedback device 5.

[0045] The aperture and depth dimensions can be adjusted in the X, Y, and Z directions by the telescopic movement of the three-axis telescopic frame, thus covering horn specifications with different gains in all frequency bands. Compared to the traditional method of processing a separate horn antenna for each specification, this device achieves "one device for multiple frequencies and multiple gains," significantly reducing the number of spare parts and inventory volume. After setting the specified dimensions, the control system adjusts and corrects the actual dimensions based on feedback data from three distance feedback devices. Only the metal covering layer 6 needs to be placed on the three-axis telescopic frame to meet the testing needs of one horn antenna. This device can achieve greater efficiency and can be widely used in the microwave testing field. The distance feedback device 5 transmits the aperture dimensions back to the control unit in real time, and the control unit makes PID corrections based on the feedback. Therefore, the reconstructed horn antenna has the same or even higher repeatability in RF indicators such as VSWR and gain as traditional fixed-size horns. When the test frequency band or gain requirements change, you only need to input the new size into the human-machine interface, and the system will automatically complete the three-axis telescopic frame, size confirmation and re-attachment of the metal cover layer 6. The whole process does not require disassembly or assembly of any mechanical parts, realizing "one-time installation and multiple reconstructions", which significantly shortens the test preparation time.

[0046] Both the transverse electrically controlled telescopic component 2 and the longitudinal electrically controlled telescopic component 3 include a hollow stepper motor 12, a second trapezoidal lead screw 13 that rotates in both directions, two push rods 14, and two support rods 15. The two support rods 15 are respectively located on both sides of the hollow stepper motor 12. The output end of the hollow stepper motor 12 is coaxially connected to the second trapezoidal lead screw 13. The forward thread section and the reverse thread section of the second trapezoidal lead screw 13 are respectively threaded with the two push rods 14. The push rods 14 are slidably sleeved inside the support rods 15, and pins 21 are provided on the push rods 14 for support. The surface of rod 15 has a pin guide groove 16 that slides with pin 21; the outer end of each push rod 14 is hinged to the side wall of the retaining rod 10 of the corresponding depth-direction electrically controlled telescopic component 4, which can convert the rotational force of the second trapezoidal lead screw 13 into linear motion. When the hollow stepper motor 12 rotates, the two trapezoidal lead screws 13 in the positive and negative directions cause the two push rods 14 to move to the sides or center. When the motion occurs, the pin 21 slides in the pin guide groove 16, which can effectively control the torque generated during rotation and prevent the hollow stepper motor 12 from rotating on its own. The structures inside the transverse electrically controlled telescopic component 2 and the longitudinal electrically controlled telescopic component 3 are the same, except that they control the transverse and longitudinal areas of the rectangular opening frame, respectively.

[0047] The depth-direction electrically controlled telescopic component 4 includes a telescopic motor 8, a first trapezoidal lead screw 9, a retaining rod 10, and a fixing rod 11. The retaining rod 10 and the fixing rod 11 are respectively disposed at the Z-axis of the telescopic motor 8. To both sides, the first trapezoidal lead screw 9 passes sequentially through the retaining rod 10, the telescopic motor 8, and the fixing rod 11. The first trapezoidal lead screw 9 is threadedly connected to the telescopic motor 8. The end of the first trapezoidal lead screw 9 away from the telescopic motor 8 is movably connected to the four corners of the radiating port of the horn antenna. The end of the fixing rod 11 away from the telescopic motor 8 is movably connected to the wave module 1. When the output shaft of the telescopic motor 8 drives the first trapezoidal lead screw 9 to rotate, the two ends of the first trapezoidal lead screw 9 are guided by the through holes of the retaining rod 10 and the fixing rod 11. The right-angle connector 20 can rotate and limit the first trapezoidal lead screw 9, thereby converting the rotational motion into the linear telescopic motion of the first trapezoidal lead screw 9 along the Z direction, realizing the overall telescopic motion of the electrically controlled telescopic component 4 along the Z direction in the depth direction. The retaining rod 10 plays the role of supporting the first trapezoidal lead screw 9. When the telescopic motor 8 rotates, it drives the first trapezoidal lead screw 9 to telescopic, thereby changing the depth direction.

[0048] Four depth-direction electrically controlled telescopic components 4 are provided, and the four depth-direction electrically controlled telescopic components 4 are distributed in a rectangular quadrangle around the central axis of the wave-coating module 1; and the rear end of each depth-direction electrically controlled telescopic component 4 is movably connected to the absorbing plate 22, and the front end extends away from the wave-coating module 1 to form a Z-direction quadrangular structure; the surface of the Z-direction quadrangular structure formed by the four depth-direction electrically controlled telescopic components 4 is a variable cross-section horn antenna radiating aperture surface, and is covered with a metal covering layer 6.

[0049] The lateral electrically controlled telescopic component 2 spans between the two depth-direction electrically controlled telescopic components 4 along the X-direction, with its two ends rotatably connected to the corresponding depth-direction electrically controlled telescopic components 4; and there are two lateral electrically controlled telescopic components 2 in the three-axis telescopic frame, symmetrically distributed along the Y-direction; the longitudinal electrically controlled telescopic component 3 spans between the two depth-direction electrically controlled telescopic components 4 along the Y-direction, with its two ends rotatably connected to the corresponding depth-direction electrically controlled telescopic components 4; and there are two lateral electrically controlled telescopic components in the three-axis telescopic frame, symmetrically distributed along the X-direction.

[0050] The front end of the three-axis telescopic frame is provided with a rectangular opening frame formed by four guide telescopic components 7 connected end to end. The four corners of the rectangular opening frame are rotatably connected to the front ends of the four depth-direction electrically controlled telescopic components 4, and the four guide telescopic components 7 are connected end to end by right-angle connectors 20 to form the rectangular opening frame. The length and width of the rectangular opening frame change synchronously with the extension and retraction of the transverse electrically controlled telescopic component 2 and the longitudinal electrically controlled telescopic component 3, and after adjustment, the rectangular opening size is fastened and maintained by rotating the fastening knob 19.

[0051] The two ends of the depth-direction electrically controlled telescopic component 4 are movably connected to the wave module 1 and the guide telescopic component 7, respectively, so that the depth-direction electrically controlled telescopic component 4 can rotate around the X-axis and Y-axis. The two ends of the transverse electrically controlled telescopic component 2 and the longitudinal electrically controlled telescopic component 3 are movably connected to the corresponding depth-direction electrically controlled telescopic component 4, so that both the transverse electrically controlled telescopic component 2 and the longitudinal electrically controlled telescopic component 3 can rotate around the Z-axis.

[0052] The beam reconfigurable horn antenna device is mainly composed of 4 guide telescopic components 7, 2 transverse electrically controlled telescopic components 2 (X direction), 2 longitudinal electrically controlled telescopic components 3 (Y direction), 4 depth-direction electrically controlled telescopic components 4 (Z direction), 3 distance feedback devices 5, and 1 absorbing plate 22. The absorbing plate 22 is set between the beam reconfigurable module 1 and the triaxial telescopic frame and is fixed to the flange surface of the beam reconfigurable module 1 by adhesive or screw connection to reduce back radiation.

[0053] When the hollow stepper motor 12 rotates forward, the horizontal electronically controlled telescopic component 2 and the vertical electronically controlled telescopic component 3 extend to both sides, and retract in the opposite direction; the depth-direction electronically controlled telescopic component 4 extends forward as the telescopic motor 8 rotates forward and retracts backward in the opposite direction; the guide telescopic component 7 is located at the maximum opening position of the device and is equipped with a distance feedback device 5 for feedback of the final actual position.

[0054] The guide telescopic component 7 includes an outer rod 17, an inner rod 18, and a fastening knob 19. The inner rod 18 is slidably sleeved inside the outer rod 17. The fastening knob 19 is located on the side wall of the outer rod 17 and is used to lock and position the inner rod 18 after sliding. The ends of the outer rod 17 and the inner rod 18 that are far apart from each other are fixed to the right-angle connector 20 by threads. The guide telescopic component 7 is equipped with a manual fastening function. When it reaches the designated position, the guide telescopic component 7 can be manually fixed to ensure stability. The guide telescopic component 7 is a bidirectional free telescopic mechanism that follows the movement of the transverse electrically controlled telescopic component 2 and the longitudinal electrically controlled telescopic component 3.

[0055] Three distance feedback devices 5 are provided. The first distance feedback device 5 is installed in the middle of the outer rod 17 of the guide telescopic component 7, with the detection direction facing the Z direction, and is used for depth distance detection. The second distance feedback device 5 is set on one of the edges of the rectangular opening frame, with the detection direction facing the X direction, and is used for length distance detection. The third distance feedback device 5 is set on the other edge of the rectangular opening frame, with the detection direction facing the Y direction, and is used for width distance detection.

[0056] Generally, the beamwidth of horn antennas in different frequency bands is fixed, while the aperture and length of horn antennas with different gains vary. This structure and method are applicable to horn antennas with different gains in all frequency bands. The metal covering layer 6 can be made of metal materials such as copper foil that meet electromagnetic reflection shielding requirements, and is attached at a designated location to form a complete horn antenna. The control unit uses closed-loop control to ensure that the actual dimensions match the target dimensions. This beam-reconfigurable horn antenna device has a simple, compact, and high structural strength, and can be used for horn antennas in various frequency bands and gains, possessing high development and application potential.
