Description
Technical Field
[0001] This utility model relates to the microwave field, and more specifically, to a feed support and a feed system. Background Technology
[0002] The feed is a fundamental component of parabolic antennas and Cassegrain antennas, serving as the primary radiator of a high-gain antenna. It converts high-frequency current or confined electromagnetic waves into radiated electromagnetic energy and is typically a weakly directional antenna. As an important part of an anechoic chamber compact field system, the feed is usually mounted on a feed bracket. By adjusting the X, Y, and Z axes, as well as the elevation and azimuth axes of the feed bracket, the phase center of the feed is aligned with the focal point of the compact field reflector. The higher the alignment accuracy, the higher the accuracy of the entire testing system.
[0003] Most existing feed supports use electronic control to achieve five-axis motion adjustment. Although the accuracy after adjustment can meet the requirements, the structure of the entire support is complex and the cost of shaft production and assembly is high. On the other hand, feed supports that use non-electronic control can only adjust the accuracy of the X, Y, and Z axes, but cannot make precise adjustments to the pitch and azimuth axes.

The multiple fine-tuning screws are connected to the azimuth plate and can be finely adjusted along the Z and pitch directions by adjusting the multiple fine-tuning screws. Mounting bracket, which is connected to multiple fine-tuning screws, is used to mount the feed source.
[0006] Optionally, the adjusting block is connected to the base, and the adjusting block is also connected to a fine-tuning screw, which is used to push the top plate to move along the X-axis and Y-axis to achieve fine-tuning in the X-axis and Y-axis.
[0007] Optionally, the adjusting block is also connected to an azimuth fine-tuning component, which is used to drive the azimuth plate to rotate.
[0008] Optionally, the top plate is provided with a circular protrusion, and the orientation plate is provided with a circular groove. The circular protrusion is accommodated in the circular groove, and the circular protrusion and the circular groove are concentrically fitted.

Fine-tuning of the feed along the X and Y axes can be achieved by adjusting the multiple adjusting blocks. The azimuth plate is rotatably connected to the top plate. Since the multiple fine-tuning screws are connected to the azimuth plate and the mounting base is connected to the multiple fine-tuning screws, adjusting the multiple adjusting blocks can drive the azimuth plate to rotate around the top plate, thereby driving the multiple fine-tuning screws and the mounting base to rotate, thus achieving azimuth adjustment of the feed. Fine-tuning of the feed along the Z and pitch axes can be achieved by adjusting the position of the mounting base on the multiple fine-tuning screws.

[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0028] With the rapid development of communication and aviation technologies, the demand for radar cross section (RCS) testing in microwave anechoic chambers has increased dramatically, and the requirements for the quiet zone performance of anechoic chambers are becoming increasingly stringent. The feed is a fundamental component of parabolic antennas and Cassegrain antennas, serving as the primary radiator of a high-gain antenna. The feed converts high-frequency current or confined electromagnetic waves into radiated electromagnetic energy, typically functioning as a weakly directional antenna. As an important part of the anechoic chamber's compact field system, the feed is usually mounted on a feed bracket. By adjusting the X, Y, and Z axes, as well as the elevation and azimuth axes of the feed bracket, the phase center of the feed is aligned with the focal point of the compact field reflector. The higher the alignment accuracy, the higher the overall accuracy of the testing system.
[0029] Existing feed supports mostly use electronic control to achieve five-axis motion adjustment. Although the accuracy after adjustment can meet the requirements, the structure of the entire support is complex and the cost of shaft production and assembly is high. On the other hand, feed supports that use non-electronic control can mostly only adjust the accuracy of the X, Y, and Z axes, but cannot accurately adjust the pitch and azimuth axes.
[0030] In view of the above problems, the present invention provides a feed bracket and a feed system, which can solve the above problems, and will be described in detail below.
[0031] Please refer to Figure 1 The feed support includes a base 1, a fine-tuning component 2, and a mounting base 3. The feed 4 is mounted on the mounting base 3. The fine-tuning component 2 includes a top plate 20, an azimuth plate 21, multiple adjusting blocks 22, and multiple fine-tuning screws 23. The top plate 20 is movably connected to the base 1 and can be finely adjusted along the X-axis and Y-axis by adjusting the multiple adjusting blocks 22. The azimuth plate 21 is rotatably engaged with the top plate 20 and can be finely adjusted in azimuth by adjusting the multiple adjusting blocks 22. The multiple fine-tuning screws 23 are connected to the azimuth plate 21 and can be finely adjusted in the Z-axis and pitch direction by adjusting the multiple fine-tuning screws 23.
[0032] The feed bracket of this utility model can achieve fine adjustment of the feed 4 in the X and Y axes by adjusting multiple adjusting blocks 22. The azimuth plate 21 and the top plate 20 are rotatably connected. Since multiple fine adjusting screws 23 are connected to the azimuth plate 21 and the mounting base 3 is connected to the multiple fine adjusting screws 23, the azimuth plate 21 can be rotated around the top plate 20 by adjusting multiple adjusting blocks 22, thereby driving the multiple fine adjusting screws 23 and the mounting base 3 to rotate, thereby realizing the azimuth adjustment of the feed 4 connected to the mounting base 3. By adjusting the position of the mounting base 3 on the multiple fine adjusting screws 23, the Z axis and pitch direction of the feed 4 can be finely adjusted. Compared to the complex structural design of existing electrically controlled feed brackets, the feed bracket of this utility model embodiment has a simple structure and low production and manufacturing costs. Compared with the same type of manually adjustable feed bracket, this feed bracket can achieve fine adjustment of the X-axis, Y-axis, Z-axis, azimuth axis and pitch direction through manual operation, which can meet the accuracy requirements of the coincidence of the feed 4 phase center and the focal point of the compact field reflecting surface.
[0033] Specifically, base 1 is placed on the ground, serving as support and for rough adjustment. (Reference) Figure 2 and Figure 3 The base 1 includes a hollow sleeve and an upper plate and a lower plate fixed to both ends of the hollow sleeve. Both the upper plate and the lower plate are rectangular plates. The lower plate has cross-shaped holes 11 near each of its four corners. Each cross-shaped hole 11 has two mutually perpendicular slots, which are interconnected at their midpoints and oriented towards the X-axis and Y-axis, respectively. Anchor bolts 12 are pre-embedded in the ground. The position of the anchor bolts 12 is fixed according to the layout of the darkroom. The upper end of the anchor bolts 12 is exposed and can pass through the cross-shaped holes 11. The lower plate of the base 1 can move horizontally along the X-axis and Y-axis relative to the position of the anchor bolts 12, thereby achieving coarse adjustment of the base 1 in the X-axis and Y-axis. The outer diameter of the anchor bolt 12 is slightly smaller than the width of the two slots in the cross-shaped hole 11. This allows the base 1 to move horizontally only relative to the anchor bolt 12 along the X and Y axes. Of course, the base 1 can also move along the anchor bolt 12 along the Z axis, thus enabling coarse adjustment of the base 1 in the X, Y, and Z axes. It should be noted that the length of the two slots in the cross-shaped hole 11 can be set as needed; the greater the length, the wider the adjustable range of the base 1. There is no limitation on the length of the two slots in the cross-shaped hole 11.
[0034] The upper plate of the base 1 is provided with multiple screw holes, which are distributed around the edge of the upper plate. The upper plate is used to install the fine adjustment component 2. The fine adjustment component 2 is connected and locked to the upper plate through the positioning locking component 10. Of course, the fine adjustment component 2 is connected and locked to the upper plate after it is adjusted to the correct position. During the adjustment process, the fine adjustment component 2 can move relative to the upper plate.
[0035] refer to Figure 4 and Figure 5 The fine-tuning component 2 includes a top plate 20, an orientation plate 21, an adjusting block 22, and a fine-tuning screw 23. The top plate 20 is a square plate with a circular protrusion 201 in its center. The orientation plate 21 is an annular flat plate with a circular groove 211 in its center. When the orientation plate 21 and the top plate 20 are assembled together, the circular protrusion 201 of the top plate 20 is accommodated in the circular groove 211 of the orientation plate 21. The circular protrusion 201 and the circular groove 211 are concentrically fitted, facilitating the rotation of the orientation plate 21 around the circular protrusion 201 to achieve fine-tuning in orientation.
[0036] Fine-tuning positioning holes 202 are provided near the four sides of the top plate 20. The fine-tuning positioning holes 202 can also be cross-shaped holes 11. The length of the cross-shaped holes 11 is smaller than that of the cross-shaped holes 11 on the base 1. The positioning locking member 10 connected to the upper plate of the base 1 passes through the cross-shaped holes 11 of the top plate 20. When the top plate 20 is finely adjusted along the X-axis and Y-axis, the positioning locking member 10 can move within the cross-shaped holes 11 of the top plate 20, so that the positioning locking member 10 does not interfere with the fine adjustment of the top plate 20. Optionally, the positioning locking member 10 is a bolt and a nut. The bolt passes through the screw hole of the upper plate of the base 1 and then through the cross-shaped holes 11 of the top plate 20. The nut is not installed during the fine adjustment of the top plate 20. After the fine adjustment is completed, the nut is tightened onto the bolt, thereby fixing the top plate 20 and the base 1 together and realizing the positioning after fine adjustment.
[0037] The number of cross-shaped holes 11 on the top plate 20 is not limited. In this embodiment, the top plate 20 has eight cross-shaped holes 11, four of which are distributed near the four corners of the top plate 20, and the other four are distributed in the middle near the four sides of the top plate 20, which corresponds to the screw hole position of the upper plate of the base 1.
[0038] An arc-shaped waist hole 212 is provided on the azimuth plate 21. The position of the arc-shaped waist hole 212 corresponds to the positioning locking member 10 connected to the middle of the side of the top plate 20. The top of the positioning locking member 10 passes through the fine adjustment positioning hole 202 in the middle of the side of the top plate 20 and then through the arc-shaped waist hole 212 of the azimuth plate 21 to facilitate positioning and locking of the azimuth plate 21 after fine adjustment of its orientation. When the positioning locking member 10 consists of a bolt and a nut, the bolt passes through the arc-shaped waist hole 212 and is exposed. The nut can be connected to the exposed part of the bolt. When it is necessary to position and lock the azimuth plate 21 onto the top plate 20, the nut on the bolt is turned so that the nut presses the azimuth plate 21 onto the top plate 20. When it is necessary to adjust the azimuth plate 21, the nut on the bolt is loosened. At this time, the bolt and nut do not affect the rotation of the azimuth plate 21. Among them, four arc-shaped waist holes 212 are opened along the outer periphery of the circular groove 211, and the four arc-shaped waist holes 212 can be on the same circumference.
[0039] The number of adjusting blocks 22 can also be four. The four adjusting blocks 22 are respectively set on the outer middle of the four sides of the top plate 20. The four adjusting blocks 22 have the same structure and can all be L-shaped blocks. The adjusting blocks 22 are fixed to the upper plate of the base 1 by two screws. The adjusting blocks 22 are also movably connected to the fine adjustment screws 221. After the fine adjustment screws 221 pass through the adjusting blocks 22, their end faces abut against the side walls of the top plate 20. When the fine adjustment screws 221 are turned, the fine adjustment screws 221 can push the top plate 20 to move in the X-axis and Y-axis, so as to achieve fine adjustment of the top plate 20 in the X-axis and Y-axis.
[0040] The outer peripheral wall of the azimuth plate 21 has protruding lugs, and the top of the adjusting block 22 is provided with a through slot, in which the lugs are engaged and movable. Specifically, azimuth fine-tuning threaded holes are provided on both side walls of the slot, along the X and Y axes. An azimuth fine-tuning component 222, which can be an azimuth screw, is installed in the azimuth fine-tuning threaded holes. The lugs also have threaded holes. The azimuth screw passes through the azimuth fine-tuning threaded holes and the threaded holes on the lugs in sequence, connecting the azimuth plate 21 and the adjusting block 22 together. When the azimuth of the azimuth plate 21 needs to be finely adjusted, the azimuth screw can be turned. The azimuth screw is equivalent to the adjusting block 22 rotating without moving, while the azimuth plate 21 moves relative to the azimuth screw. The azimuth plate 21 rotates around the circular protrusion 201, thereby achieving the azimuth fine-tuning of the azimuth plate 21.
[0041] The lower end of the fine-tuning screw 23 is connected to the orientation plate 21, and the fine-tuning screw 23 and the orientation plate 21 are fixedly fitted together. At least two nuts are threaded onto the fine-tuning screw 23.
[0042] refer to Figure 6 The mounting base 3 includes an upper plate 30, a lower plate 31, a side plate 32, and an inclined plate 33. The upper plate 30 and the lower plate 31 are arranged opposite each other, and the side plate 32 is arranged between the upper plate 30 and the lower plate 31, connecting the upper plate 30 and the lower plate 31 together. The width of the upper plate 30 is smaller than that of the lower plate 31. The inclined plate 33 is installed at an angle on the upper plate 30 and the lower plate 31, and the inclined plate 33 is also connected to the side plate 32. The lower plate 31 is provided with multiple large-diameter through holes, the positions of which correspond to the positions of multiple fine-tuning screws 23, and the diameter of the large-diameter through holes is larger than the outer diameter of the fine-tuning screws 23. When the mounting base 3 is connected to the fine adjustment screw 23, the upper end of the fine adjustment screw 23 passes through the large-diameter through hole of the lower plate 31. The upper and lower surfaces of the lower plate 31 are respectively connected to the two nuts sleeved on the fine adjustment screw 23. The lower plate 31 is positioned by the two nuts, thereby positioning the entire mounting base 3 and the feed source 4 on the mounting base 3.
[0043] When the two nuts on multiple fine-tuning screws 23 are turned at the same speed, the Z-axis accuracy of the mounting base 3 can be adjusted. When the two nuts on multiple fine-tuning screws 23 are turned at different speeds, the mounting base 3 can be tilted to the horizontal plane to achieve pitch adjustment. Since the diameter of the large-diameter through hole on the lower plate 31 of the mounting base 3 is larger than the outer diameter of the fine-tuning screw 23, the large-diameter through hole provides sufficient room for movement when the mounting base 3 is pitched, and the fine-tuning screw 23 will not be constrained.
[0044] Optionally, the side plate 32 and the top plate 20 are hollowed out to reduce the weight of the mounting base 3.
[0045] The inclined plate 33 is also provided with a mounting position 331 for mounting the feed source 4. In this embodiment, the mounting position 331 on the inclined plate 33 is a groove with a ring of screw holes inside.
[0046] Feed 4 is mounted on feed fixture 5, which is connected to inclined plate 33. For details, please refer to [reference needed]. Figure 7 The feed fixture 5 includes an annular plate 50, multiple support rods 51, and a mounting plate 52. One end of each support rod 51 is spaced apart and connected to the annular plate 50. The mounting plate 52 is connected to the other end of each support rod 51. The annular plate 50 has multiple threaded holes that correspond to the threaded holes on the inclined plate 33. The annular plate 50 and the inclined plate 33 can be connected together using screws. At the same time, the groove on the inclined plate 33 can limit the annular plate 50, facilitating quick alignment, preventing displacement of the annular plate 50, and ensuring the concentric positioning accuracy of the two. Multiple feed sources 4 can be arranged on the mounting plate 52, and the specific number can be set as needed.
[0047] Optionally, a reinforcing washer 13 is also provided between the anchor bolt 12 and the base 1, which increases the contact area and stability when connected by a nut. The reinforcing washer 13 can be a metal washer.
[0048] It is worth mentioning that in this embodiment, the X-axis, Y-axis, Z-axis, azimuth axis, and pitch direction are as follows: Figure 1 As shown in the image.
[0049] The feed bracket of this utility model embodiment is used as follows: According to the layout dimensions of the darkroom, first pre-embed four anchor bolts 12 to the ground at the installation position of the base 1. Then install the nut, reinforcing washer 13 (lower), base 1, reinforcing washer 13 (upper), and nut onto the anchor bolts 12 in sequence. Initially adjust the height of the base 1 from the ground (Z-axis) and the position of the X-axis and Y-axis. For example, the X-axis and Y-axis can be adjusted by ±20mm, and the Z-axis can be adjusted by ±50mm.
[0050] Then, the four adjusting blocks 22 are locked to the base 1 with three screws. The top plate 20 and the orientation plate 21 are then placed on the upper surface of the base 1. The L-shaped adjusting blocks 22 are inserted into the fine-tuning screws 221 in the initial state for adjustment. After the top plate 20 and the orientation plate 21 are assembled, the fine-tuning positioning holes 202 are aligned with the positioning locking parts 10. At this time, the nuts are not tightened. The mounting base 3 and the feed fixture 5 are connected into a component using screws.
[0051] Screw the lower ends of the three fine-tuning screws 23 (fine-thread screws) into the orientation plate 21 and lock them with nuts. Connect the upper ends to the mounting base 3 with double nuts. Adjustment is required.
[0052] Feed 4 is installed onto feed fixture 5. After installation, the focal coordinates of the reflector are first located using a laser tracker. Then, the phase center of feed 4 is coarsely adjusted to coincide with the focal point of the reflector using the cross-shaped hole 11 on base 1 and the anchor bolts 12, and the nuts on the anchor bolts 12 are tightened. A coordinate system is established using the laser tracker, and the nuts on the three fine-tuning screws 23 are finely adjusted until the pitch angle of feed 4 meets the design specifications, and then locked. Fine-tuning of the X-axis, Y-axis, and azimuth axis is achieved by turning the fine-tuning screws 221 on the L-shaped adjusting block 22 and the azimuth screw, so that the phase center coincides with the focal point with an accuracy of 0.001mm. Finally, the top plate 20 and the azimuth plate 21 are tightened, and the manual fine-tuning of the feed bracket is completed.
[0053] An embodiment of this utility model also provides a feed system, including at least one feed 4 and the aforementioned feed bracket, wherein the feed 4 is mounted on the mounting position 331 of the mounting base 3 via a feed fixture 5.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
