Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of antenna testing, in particular to an antenna positioning device and an antenna testing system. Background Art
[0002] During antenna testing, the angle of the antenna under test relative to the receiving antenna must be constantly adjusted to more comprehensively evaluate its performance. Mechanical adjustments, such as those using a gear and rack mechanism, can wear out over repeated use, reducing adjustment accuracy. Directly calibrating the angle with the human eye is also prone to errors and requires significant effort.

Certain specific details are described in detail in the detailed description of the present invention below. Those skilled in the art will be able to fully understand the present invention without these details. To avoid obscuring the essence of the present invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0080] Figure 1 Schematic diagram of the antenna positioning device of this embodiment. Figure 2Schematic diagram of an exploded view of the antenna positioning device of this embodiment.
[0081] In some embodiments, as Figure 1-Figure 2 As shown, the antenna positioning device in this embodiment includes a magnetic component 1, a support portion 2, and a bearing portion 3. The support portion 2 includes an axis core 21. The bearing portion 3 includes an antenna receiving frame 31 and a sleeve 32. The bearing portion 3 is rotatably mounted on the axis core 21 via the sleeve 32.
[0082] Specifically, the shaft core 21 is a cylinder, and the sleeve 32 is a tubular structure. The sleeve 32 and the shaft core 21 have the same length, and the sleeve 32 and the shaft core 21 are clearance-matched.
[0083] Figure 3 Schematic diagram of the structure of the support portion 2 and the bearing portion 3 of this embodiment. Figure 4 It is a partial schematic diagram of the supporting portion 2 and the bearing portion 3 of this embodiment. Figure 5 3 is a schematic cross-sectional view of the supporting portion 2 and the bearing portion 3 of this embodiment.
[0084] Further reference Figure 3-Figure 5 As shown, the magnetic component 1 includes a first magnetic member 11 provided on the socket 32 and a second magnetic member 12 provided on the shaft core 21. The materials of the first magnetic member 11 and the second magnetic member 12 include but are not limited to neodymium iron boron strong magnets, permanent ferrite magnets, samarium cobalt magnets, aluminum nickel cobalt magnets or iron chromium cobalt magnets.
[0085] Figure 6 3 is an exploded view of the support portion 2 and the bearing portion 3 of this embodiment. The magnetic component 1 of this embodiment further includes a third magnetic member 13 disposed on the sleeve 32 and a fourth magnetic member 14 disposed on the connecting rod 22.
[0086] Figure 7 1 is a schematic structural diagram of the first magnetic member 11 of this embodiment. The structure of the second magnetic member 12 can be configured to be the same as that of the first magnetic member 11, so as to facilitate the assembly of the antenna positioning device.
[0087] Figures 8-13 Schematic diagram of the position of the magnetic component 1 in different implementations of this embodiment.
[0088] Further reference Figures 8-10 As shown, in the rotation direction of the carrying portion 3, the antenna accommodating frame 31 has multiple target states 6. When the antenna accommodating frame 31 rotates to different target states 6, the antenna A to be tested installed in the antenna accommodating frame 31 will face different directions.
[0089] Therefore, when the antenna A to be tested is in different target states 6 , the relative position of the antenna A to be tested and the signal receiving antenna in a fixed position changes, so as to test the radiation performance of the antenna A to be tested.
[0090] In some embodiments, as Figures 8-12 As shown, the magnetic component 1 is configured such that there are multiple first magnetic members 11, and the multiple first magnetic members 11 are spaced apart along the circumference of the socket 32, and there is at least one second magnetic member 12. In this embodiment, when there are multiple first magnetic members 11, there is one second magnetic member 12 or multiple second magnetic members 12 spaced apart.
[0091] In other embodiments, Figures 8-11 As shown, the magnetic component 1 is configured such that there are multiple second magnetic members 12, and the multiple second magnetic members 12 are spaced apart along the circumference of the shaft core 21, and there is at least one first magnetic member 11. In this embodiment, when there are multiple second magnetic members 12, there is one first magnetic member 11 or multiple first magnetic members 11 spaced apart.
[0092] In some embodiments, as Figures 8-12 As shown, the magnetic component 1 is further configured so that when the antenna housing 31 is in any target state 6, the at least one first magnetic member 11 and the at least one second magnetic member 12 attract each other to relative positions. Thus, the first magnetic member 11 and the second magnetic member 12 are used to position the support portion 2 relative to the carrier portion 3, maintaining the position accuracy of the antenna A under test.
[0093] In some embodiments, as Figure 13 As shown, the magnetic component 1 is further configured so that when the antenna housing 31 is located between two adjacent target states 6, the first magnetic member 11 is staggered from all the second magnetic members 12. This allows the operator to continuously rotate the carrier 3 to adjust the orientation of the antenna A under test, preventing the magnetic force of the magnetic component 1 from affecting the rotation of the antenna housing 31.
[0094] In summary, the antenna positioning device in this embodiment rotatably connects the socket 32 to the shaft core 21 so that the support part 2 and the bearing part 3 form a rotating pair. Thus, the operator can adjust the setting angle of the antenna A to be tested by rotating the bearing part 3. Therefore, on the one hand, the first magnetic part 11 is set on the socket 32, and the second magnetic part 12 is set on the shaft core 21. When the antenna accommodating frame 31 is rotated to the target state 6, the first magnetic part 11 can just attract the second magnetic part 12 to accurately position the relative position of the support part 2 and the bearing part 3. On the other hand, when the antenna accommodating frame 31 is staggered from the target state 6, the first magnetic part 11 is also staggered from the second magnetic part 12. When the operator rotates the antenna accommodating frame 31, he can feel the change in magnetic attraction. Thus, by the magnitude of the magnetic attraction, it is determined whether the current antenna A to be tested is in the target state 6.
[0095] In some embodiments, as Figure 7-Figure 8 As shown, the first magnetic member 11 and the second magnetic member 12 both include a first magnetic pole 41 and a second magnetic pole 42 with opposite polarities. The first magnetic pole 41 of the first magnetic member 11 is arranged close to the shaft core 21, and the second magnetic pole 42 of the second magnetic member 12 is arranged close to the socket 32.
[0096] Optionally, the first magnetic pole 41 is an N pole and the second magnetic pole 42 is an S pole. The arrangement positions of the first magnetic member 11 and the second magnetic member 12 in this embodiment can ensure that the magnetic component 1 provides sufficient magnetic attraction.
[0097] In some embodiments, as Figure 7-Figure 8 As shown, the first magnetic member 11 and the second magnetic member 12 are both strip-shaped structures, with the first magnetic pole 41 and the second magnetic pole 42 at both ends of the strip-shaped structure, and the length direction of the strip-shaped structure is arranged along the radial direction of the shaft core 21.
[0098] This helps to arrange the first magnetic part 11 and the second magnetic part 12, especially when the number of the first magnetic part 11 and the second magnetic part 12 is large, so that the magnetic field of the magnetic component 1 can be effectively distributed, ensuring that when the antenna accommodating frame 31 is in the target state 6, the first magnetic part 11 and the second magnetic part 12 attract each other, and at the same time, when the antenna accommodating frame 31 is in a position offset from the target state 6, the first magnetic part 11 and the second magnetic part 12 can also be offset from each other.
[0099] In some embodiments, as Figure 4 and Figure 8As shown, the sleeve 32 is loosely fitted with the shaft core 21. The end surface of the first magnetic pole 41 of the first magnetic member 11 is exposed to the inner sidewall of the sleeve 32, and the end surface of the second magnetic pole 42 of the second magnetic member 12 is exposed to the outer sidewall of the shaft core 21. This increases the magnetic attraction between the first magnetic member 11 and the second magnetic member 12, facilitates the relative rotation of the shaft core 21 and the sleeve 32, and reduces the resistance between the two.
[0100] In some embodiments, as Figure 7 As shown, the strip structure includes a fixing body 43. In the direction of extension of the strip structure, the cross-sectional area of the fixing body 43 is larger than the cross-sectional area of the first magnetic pole 41 and the second magnetic pole 42. As a result, the magnetic component 1 can be stably connected to the support portion 2 and the bearing portion 3, preventing the first magnetic member 11 and the second magnetic member 12 from attracting each other and causing the first magnetic member 11 and the second magnetic member 12 to become loose.
[0101] In some embodiments, as Figure 4-Figure 5 As shown, the support portion 2 further includes a connecting rod 22, and the shaft core 21 is protruding from the side of the connecting rod 22. The sleeve 32 and the shaft core 21 both have a plurality of fixing grooves 51, which are respectively located at the ends of the sleeve 32 and the shaft core 21 away from the connecting rod 22, and the first magnetic member 11 and the second magnetic member 12 are disposed in the fixing grooves 51.
[0102] Specifically, the fixing groove 51 on the socket 32 and the shaft core 21 has a notch, and the fixing groove 51 is open toward the side away from the connecting rod 22 through the notch, so that the operator can insert the first magnetic component 11 and the second magnetic component 12 into the fixing groove 51 from the end of the socket 32 and the shaft core 21, thereby simplifying the installation method of the magnetic component 1.
[0103] In other embodiments, Figure 1-Figure 4 As shown, the shaft core 21 and the socket 32 are both injection-molded parts. Furthermore, at least a portion of the first magnetic member 11 and at least a portion of the second magnetic member 12 are disposed within the injection-molded part. In this embodiment, the magnetic component 1 is positioned as an insert within the injection-molded part, making the antenna positioning device more compact. This simplifies the installation of the magnetic component 1, particularly when the first and second magnetic members 11, 12 are relatively small.
[0104] In some embodiments, as Figure 3 As shown, the connecting rod 22 has a support surface 221, the shaft core 21 is protruding from the support surface 221, and the end of the sleeve 32 away from the fixing groove 51 abuts against the support surface 221. In this embodiment, the shaft core 21 stands upright on the top of the connecting rod 22, and the support surface 221 is used to support the sleeve 32 so that it can rotate on the support surface 221.
[0105] In some embodiments, as Figure 3As shown, there are multiple first magnetic members 11, which form multiple groups of first magnetic members 11. The multiple groups of first magnetic members 11 are distributed along the axial direction of the sleeve 32. There are multiple second magnetic members 12, which form multiple groups of second magnetic members 12 corresponding to the multiple groups of first magnetic members 11.
[0106] Therefore, by arranging multiple groups of first magnetic members 11 and multiple groups of second magnetic members 12 in the bearing portion 3 and the supporting portion 2 , the internal space of the two can be fully utilized, while greatly increasing the magnetic attraction of the magnetic component 1 .
[0107] In some embodiments, as Figure 3 As shown, the support portion 2 further includes a connecting rod 22, the connecting rod 22 has a supporting surface 221, and the shaft core 21 is protruded from the supporting surface 221. Figure 6 As shown, the magnetic component 1 further includes a plurality of third magnetic members 13 disposed at the end of the sleeve member 32 and a plurality of fourth magnetic members 14 disposed on the connecting rod 22 .
[0108] The sleeve 32 abuts the support surface 221 and rotates relative to it. The at least one third magnetic member 13 and the at least one fourth magnetic member 14 are attracted to each other and positioned relative to each other. The at least one first magnetic member 11 and the at least one second magnetic member 12 are positioned relative to each other. The third magnetic member 13 and all fourth magnetic members 14 are staggered, and the first magnetic member 11 and all second magnetic members 12 are staggered.
[0109] In this embodiment, the number and position of the third magnetic members 13 and the fourth magnetic members 14 can be respectively arranged to correspond to the first magnetic member 11 and the second magnetic member 12. The third magnetic members 13 and the fourth magnetic members 14 can increase the magnetic attraction of the magnetic component 1. In addition, when the sleeve 32 and the shaft core 21 are connected to each other, the third magnetic members 13 and the fourth magnetic members 14 can ensure a quick connection between the two, so that the end of the sleeve 32 abuts against the support surface 221.
[0110] In some embodiments, as Figures 1-8 As shown, the material of the carrier portion 3 and the support portion 2 is configured to be at least one of plastic, rubber, or plastic (which can be a plastic material with low dielectric loss). The antenna housing 31 extends from the outer side of the sleeve 32. The first magnetic member 11 is disposed on the side of the sleeve 32 away from the antenna housing 31.
[0111] Thus, on the one hand, the support portion 2 and the bearing portion 3 can be manufactured by injection molding. On the other hand, the use of metal materials for the support portion 2 and the bearing portion 3 can be avoided, thereby preventing interference with the performance test of the antenna A under test. On the other hand, the influence of the magnetic component 1 on the test of the antenna A under test can be reduced.
[0112] Furthermore, the material of the magnetic component 1 is ferrite. For example, the material of the magnetic component 1 can be configured as permanent ferrite. The resistivity of permanent ferrite is much greater than that of most metal and alloy magnetic materials, and it also has a high magnetic permeability at high frequencies. Therefore, the use of permanent ferrite can reduce the impact on test results.
[0113] In some embodiments, as Figure 8 and Figure 9 As shown, the number of first magnetic members 11 and second magnetic members 12 is the same. When the antenna housing 31 is in one target state 6, the multiple first magnetic members 11 correspond one-to-one with the multiple second magnetic members 12. That is, in this embodiment, when the antenna housing 31 is in another target state 6, some of the first magnetic members 11 correspond one-to-one with some of the second magnetic members 12.
[0114] It is easy to understand that when the operator rotates the antenna accommodating frame 31, for example, Figure 8 Status turns to Figure 9 The magnetic attraction generated by the magnetic component 1 will gradually decrease. This can prompt the operator to know the rotation range of the current antenna holder 31. Furthermore, when the operator resets the antenna A to be tested, the change in magnetic attraction can also be used to determine whether the antenna A to be tested is in the initial position ( Figure 8 shown).
[0115] In some embodiments, as Figure 11 and Figure 12 As shown, there are multiple first magnetic members 11 and the number of first magnetic members 11 is greater than the number of second magnetic members 12. When the antenna receiving frame 31 rotates from one target state 6 to another target state 6, the first magnetic members 11 correspond to different second magnetic members 12 respectively.
[0116] It is easy to understand that when the antenna positioning device is in Figure 8 In the state, the magnetic component 1 is far away from the antenna A to be tested. However, when the sleeve 32 is rotated 90 degrees clockwise (such as Figure 10 As shown), the distance between the first magnetic component 11 and the antenna A to be tested remains unchanged, but most of the second magnetic components 12 will be close to the antenna A to be tested, so that the influence of the magnetic component 1 on the antenna A to be tested changes with the angle of the antenna A to be tested, thereby affecting the detection of the antenna A to be tested.
[0117] To this end, the number of second magnetic members 12 in this embodiment is configured to be relatively small, for example, the number of second magnetic members 12 can be 1, 2, 3, or 4. Furthermore, the number of second magnetic members 12 can be 13. Thus, even when the antenna housing 31 is rotated to the 90-degree position, the second magnetic member 12 can still maintain a relatively large distance from the antenna A under test.
[0118] In some embodiments, as Figures 8-11 As shown, the spacing between the plurality of first magnetic members 11 is the same, and the spacing between the plurality of second magnetic members 12 is the same and consistent with the spacing between the plurality of first magnetic members 11. Thus, the antenna accommodating frame 31 can have a larger number of target states 6 with closer spacing.
[0119] Specifically, in the circumferential direction of the shaft core 21 , the angle between two adjacent first magnetic members 11 is 15 degrees, and the angle between two adjacent second magnetic members 12 is also 15 degrees.
[0120] Thus, the angle of the antenna accommodating frame 31 can be adjusted evenly, which helps the antenna positioning device to adjust the antenna A to be tested at multiple angles. On the other hand, when the first magnetic member 11 and the second magnetic member 12 are staggered (such as Figure 13 As shown in FIG6 , the magnetic force of the two adjacent second magnetic members 12 can still act on the first magnetic member 11 to drive the antenna housing 31 to rotate. The antenna housing 31 rotates clockwise or counterclockwise to a state corresponding to one of the first magnetic members 11, preventing the antenna housing 31 from staying between the two target states 6.
[0121] In some embodiments, as Figure 1-Figure 2 As shown, the antenna positioning device also includes a stopper 7. Stopper 7 has a stopper surface 71. Stopper 7 is detachably connected to the end of shaft core 21, and stopper surface 71 is disposed opposite the end surface of sleeve 32. This embodiment utilizes stopper 7 to prevent axial movement of antenna housing 31 along shaft core 21 during rotation.
[0122] In some embodiments, as Figure 1-Figure 5 As shown, a threaded hole 211 is formed on the end surface of the shaft core 21 , and the limiting member 7 includes a stud 72 threadedly connected to the threaded hole 211 , and the length of the stud 72 is less than the depth of the threaded hole 211 .
[0123] In an optional implementation, the antenna positioning device in this embodiment can be used in the following manner: First, the antenna A to be tested is mounted on the antenna receiving frame 31, and the socket 32 is sleeved on the shaft core 21. Secondly, the stud 72 is screwed into the threaded hole 211, and it is ensured that there is a gap between the limit surface 71 and the end surface of the socket 32. Again, after adjusting the angle of the antenna receiving frame 31 to the first target state 6, the limiter 7 is tightened so that the limit surface 71 abuts against the socket 32, thereby preventing the socket 32 and the shaft core 21 from rotating relative to each other. Again, the antenna A to be tested in the first target state 6 is tested once. Again, the limiter 7 is loosened so that there is a gap between the limit surface 71 and the end surface of the socket 32, and the antenna receiving frame 31 is adjusted to the second target state 6, and the limiter 7 is tightened again. Finally, after the second test is completed, the limiter 7 is unscrewed from the threaded hole 211, and the supporting part 3 is removed.
[0124] In some embodiments, as Figure 6 As shown, the support surface 221 has an angle mark 8. In the axial direction of the shaft core 21, the antenna housing 31 partially overlaps with the angle mark 8. When the operator rotates the antenna housing 31, by observing the corresponding position of the antenna housing 31 on the angle mark 8, the angle of the antenna housing 31 can be quickly adjusted by cooperating with the magnetic component 1.
[0125] In some embodiments, as Figure 1-Figure 3 As shown, a substrate connection hole 311 is defined at the end of the antenna housing 31 away from the sleeve 32 , and the axial direction of the substrate connection hole 311 is tangent to the circumference of the sleeve 32 .
[0126] Specifically, the antenna A under test in this embodiment is a patch antenna with a through-hole formed therein for connection to the substrate connection hole 311. When the antenna A under test is mounted in the substrate connection hole 311, the thickness of the patch antenna is perpendicular to the rotation direction of the antenna mounting bracket 31. This facilitates detection of the spatial distribution of the beam in a direction perpendicular to the patch antenna substrate.
[0127] Figure 14 2 is a schematic structural diagram of the antenna testing system of this embodiment.
[0128] In some embodiments, as Figure 14 As shown, the antenna positioning device in the above embodiment can be applied to an antenna test system. The antenna test system also includes a shielding box 9. The antenna positioning device is arranged inside the shielding box 9 and is fixedly connected to the shielding box 9 through the support part 2.
[0129] Specifically, if Figure 2 As shown, the support portion 2 also includes a connecting plate 23 connected to the connecting rod 22. The connecting plate 23 is fixedly connected to the inner wall of the shielding box 9. The detachable supporting portion 3 simplifies the installation steps of the antenna A to be tested. The signal receiving antenna is set on the outside of the shielding box 9 and is opened through the side opening of the shielding box 9 (such as Figure 9 as shown) is arranged opposite to the antenna A to be tested.
[0130] In summary, the antenna testing system in this embodiment rotatably connects the socket 32 of the antenna positioning device to the shaft core 21, and uses the antenna accommodating frame 31 to install the antenna A to be tested, so that the operator can adjust the setting angle of the antenna A to be tested by rotating the bearing portion 3. Thus, on the one hand, the first magnetic member 11 is set on the socket 32, and the second magnetic member 12 is set on the shaft core 21. When the antenna accommodating frame 31 is rotated to the target state 6, the first magnetic member 11 can just attract the second magnetic member 12 to accurately locate the relative position of the support portion 2 and the bearing portion 3. On the other hand, when the antenna accommodating frame 31 is offset from the target state 6, the first magnetic member 11 is also offset from the second magnetic member 12. When the operator rotates the antenna accommodating frame 31, he can feel the change in magnetic attraction. Therefore, by the magnitude of the magnetic attraction, it is determined whether the current antenna A to be tested is in the target state 6.
