Description

Technical Field

[0001] This utility model relates to the field of probe antenna technology, and in particular to a compact integrated structure for a dual-polarized probe antenna. Background Technology

[0002] A probe antenna is an important tool for measuring antenna parameters. It is typically used in near-field test systems, where the probe antenna is moved across a specific plane to capture the radiation characteristics of the antenna under test (AUT). This technique allows for the simulation of far-field conditions within a limited space, thereby obtaining the antenna's radiation pattern, gain, and other key performance indicators.

[0003] The compact dual-polarized probe antenna combines two orthogonal polarization directions, +45° and -45°, and is fixed together with the receiver, probe, and feed network to form a unified whole. This improves the antenna's stability and reliability, and allows it to operate in full-duplex mode. This design requires only one dual-polarized antenna per cell, significantly reducing the number of antennas needed for directional base stations. Furthermore, the dual-polarized antenna allows the system to employ polarization diversity reception technology, improving signal stability and reliability. The compact, integrated design also effectively reduces losses and interference from external connections, improving the overall performance and lifespan of the dual-polarized probe antenna.

[0004] In the prior art, some dual-polarized antennas are fixed to a positioning post with screws. However, over time, the screws will rust. If they need to be disassembled for inspection, it will increase the disassembly time and reduce the maintenance efficiency. To address this issue, a compact integrated structure for dual-polarized probe antennas is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a compact integrated structure for a dual-polarized probe antenna, aiming to improve the problem in the prior art where the screws used to fix the dual-polarized probe antenna rust after a period of time, which leads to inconvenience in disassembly and reduced maintenance efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The compact integrated structure of the dual-polarized probe antenna includes a receiver and a support plate. A probe is fixedly connected to the right side of the receiver, and a support block is fixedly connected to the left side of the receiver. A stabilizing component for providing support is detachably connected to the inner wall of the support block. Multiple pins are slidably connected to the side of the support plate away from the receiver. A main shaft is fixedly connected to the adjacent side of two pins. A rotating block is rotatably connected to the side of the main shaft away from the pins. A counterweight is fixedly connected to the bottom end of the rotating block.

[0008] As a further description of the above technical solution:

[0009] The stabilizing component includes a main rod, the main rod being detachably connected to the inner wall of the support block, and multiple side blocks being fixedly connected to the outside of the main rod;

[0010] As a further description of the above technical solution:

[0011] Two washers are slidably connected to the outer left side of the main shaft, and a spring is fixedly connected to the adjacent side of the two washers.

[0012] As a further description of the above technical solution:

[0013] Triangular plates are fixedly connected to all four sides of the bottom end of the main rod, and a base plate is fixedly connected to the bottom end of the main rod.

[0014] As a further description of the above technical solution:

[0015] The chassis has multiple fixed columns fixedly connected to its inner wall, and a conical column slidably connected to the inner wall of each fixed column. A pressure rod is fixedly connected to the top of each conical column, and limit blocks are fixedly connected to both outer sides of each conical column. The outer sides of the limit blocks are slidably connected to the inner wall of the fixed columns.

[0016] As a further description of the above technical solution:

[0017] The inner wall of the fixed column has two protrusions that are slidably connected. The bottom end of the protrusions is fixedly connected to a sliding column. A spring is fixedly connected to the adjacent side of the two sliding columns. Both sides of the outer side of the pressure rod are fixedly connected to a locking plate. The locking plate is engaged with the fixed column.

[0018] As a further description of the above technical solution:

[0019] The left side of the support block contacts the right side of the support plate, and the inner wall of the support block is detachably connected to the outside of the main rod;

[0020] As a further description of the above technical solution:

[0021] The bottom end of the tapered column is in contact with the outside of the protrusion, and the bottom end of the sliding column is slidably connected to the bottom end of the inner wall of the fixed column.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the receiver needs to be disassembled and repaired, the counterweight can be rotated first so that the rotating block, the counterweight and the main shaft are horizontally related. Then the insert can be pulled to remove the main shaft and then normal maintenance work can be carried out. In addition, the position of the receiver can be selected according to the usage scenario, which improves the flexibility of this device.

[0024] 2. In this utility model, when the device needs to be installed as a whole, the fixed column can be used to break the surface of the ground first, and then inserted into the ground. Then, the pressure rod is pressed down, so that the conical column squeezes the protrusion and moves it to both sides. When it is inserted into the surrounding soil, the clamping plate will also engage with the groove on the outside of the fixed column, thus completing the installation. Compared with the bolt fixing method in the prior art, the presence of the protrusion widens the contact area between it and the ground, thereby improving the overall stability of the device.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 One embodiment of this utility model is a compact integrated structure of a dual-polarized probe antenna, including a receiver 1 and a support plate 4. The receiver 1 is used to receive signals, and a probe 2 is fixedly connected to the right side of the receiver 1. The probe 2 is used for near-field antenna measurement and can capture the radiation data of the antenna under test (AUT) in the near field. By using this data and performing near-field and far-field transformation, the far-field characteristics of the antenna radiation can be obtained. At the same time, the receiver 1 and probe 2 are fixed together to form a complete and compact integrated structure to improve the stability and reliability of the antenna, thereby reducing the loss and interference caused by external connections. A support block 3 is fixedly connected to the left side of the receiver 1. The left side of the support block 3 is in contact with the right side of the support plate 4. A stabilizing component for providing support is detachably connected to the inner wall of the support block 3. The stabilizing component includes a main rod 5. The outside of the main rod 5 is detachably connected to the inner wall of the support block 3. The support block 3 is used to fix the receiver 1 and the main rod 5 together. The inner wall of the support block 3 is detachably connected to the outside of the main rod 5. Multiple side blocks 6 are fixedly connected to the outside of the main rod 5. The side blocks 6 can adjust the position of the receiver 1 fixed on the main rod 5 according to the usage scenario. Multiple pins 7 are slidably connected to the side of the support plate 4 away from the receiver 1. The pins 7 are a locking mechanism.

[0033] A main shaft 8 is fixedly connected to the adjacent side of the two insertion posts 7. The insertion posts 7 here can cooperate with the main shaft 8 to fix the receiver 1 and the main rod 5 together. Two washers 9 are slidably connected to the outer left side of the main shaft 8. A spring 10 is fixedly connected to the adjacent side of the two washers 9. The washers 9 here provide stable support for the spring 10. A rotating block 11 is rotatably connected to the side of the main shaft 8 away from the insertion posts 7. A counterweight 12 is fixedly connected to the bottom end of the rotating block 11. The counterweight 12 here is heavier than the rotating block 11. So after the main rod 5 passes through the support block 3, it can drive the rotating block 11 to rotate, so that the rotating block 11 and the support block 3 form a perpendicular state. Thus, under the action of the spring 10, the connection between the receiver 1 and the main rod 5 is ensured.

[0034] Reference Figure 1 , Figure 2 and Figure 4Triangular plates 13 are fixedly connected to the four sides of the bottom end of the main rod 5, and a base plate 14 is fixedly connected to the bottom end of the main rod 5. The triangular plates 13 here can ensure the stability of the main rod 5 on the base plate 14. Multiple fixed columns 15 are fixedly connected to the inner wall of the chassis 14. A conical column 16 is slidably connected to the inner wall of the fixed column 15. A pressure rod 17 is fixedly connected to the top of the conical column 16. The pressure rod 17 is where the operator presses. When the pressure rod 17 is pressed, the conical column 16 can be driven to descend. Limiting blocks 18 are fixedly connected to both sides of the outer side of the conical column 16. The outer side of the limiting blocks 18 is slidably connected to the inner wall of the fixed column 15. The limiting blocks 18 here ensure the maximum distance of the conical column 16 descending. Two protrusions 19 are slidably connected to the inner wall of the fixed column 15. When the conical column 16 descends, the protrusions 19 can be squeezed to move outward and insert into the adjacent soil, thereby increasing the contact area between the device and the soil and improving stability. The bottom end of the conical column 16 contacts the outer side of the protrusion 19.

[0035] A sliding post 20 is fixedly connected to the bottom end of the protrusion 19. The sliding post 20 provides stable support for the sliding of the protrusion 19. The bottom end of the sliding post 20 is slidably connected to the bottom end of the inner wall of the fixed post 15. A spring 21 is fixedly connected to the adjacent side of the two sliding posts 20. The spring 21 is used to ensure that the two protrusions 19 can be retracted into the interior of the fixed post 15 when this fixing mechanism is not used. A locking plate 22 is fixedly connected to both sides of the external side of the pressure rod 17. The locking plate 22 is engaged with the fixed post 15. The distance that the locking plate 22 can slide outside the fixed post 15 is the same as the distance that the limiting block 18 can slide inside the fixed post 15. This ensures that the tapered post 16 does not contact the spring 21 while ensuring the engaged state of the device.

[0036] Working principle: First, depending on the scenario requirements, the receiver 1 is fixed to the main rod 5 at the desired position. Then, the support block 3 is inserted into the outside of the main rod 5, followed by the support plate 4 covering the left side of the support block 3. Next, the two main shafts 8 are inserted, connecting the side block 6, support block 3, and support plate 4 together. Simultaneously, the counterweight 12, being heavier than the rotating block 11, causes the rotating block 11 to rotate, making it perpendicular to the support plate 4. The spring 10, under the pressure of the support plate 4 and the insertion post 7, generates a reaction force, locking the mechanism in place, thus completing the installation of the receiver 1. For disassembly, simply rotate the counterweight 12 until the rotating block 11 is horizontal with the support block 3, allowing the main shaft 8 to be pulled out, completing the disassembly of the receiver 1.

[0037] When it is necessary to fix this device to the ground, first insert the fixed column 15 into the ground, then press the pressure rod 17 to squeeze the conical column 16. The conical column 16 continues to squeeze the protrusion 19, causing the protrusion 19 to move to both sides, thus inserting the protrusion 19 into the surrounding soil. At the same time, the locking plate 22 will also engage with the fixed column 15, thus completing the installation and effectively improving the stability of the device. The spring 21 here ensures that when retracting the device, the two protrusions 19 can be retracted into the fixed column 15.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
