Description

Technical Field

[0001] This utility model relates to the field of antenna testing, and more specifically, to a multi-band compatible compact field antenna testing system. Background Technology

[0002] Compact field antenna test systems, as an important antenna testing method, can simulate far-field conditions within a limited space and accurately measure the radiation characteristics of antennas. Traditional compact field antenna test systems are often designed for only a single frequency band or a few frequency bands, making it difficult to meet the needs of multi-band antenna testing. To adapt to the testing requirements of antennas in different frequency bands, it is necessary to develop a multi-band compatible compact field antenna test system.

[0003] Traditional compact field antenna test systems are typically designed for a single frequency band or a few frequency bands. In practical applications, different fields and scenarios have extremely diverse frequency band requirements for antennas. For example, 5G communication needs to support multiple frequency bands to achieve high-speed data transmission and wide coverage, while satellite communication involves multiple frequency bands such as L-band, S-band, C-band, and X-band. Such single-band or few-band test systems cannot meet the testing needs of multi-band antennas, leading to the need to change test systems when testing antennas of different frequency bands, increasing testing costs and time.

[0004] In traditional compact field antenna testing systems, the installation and adjustment methods for reflector panels are relatively fixed and singular. When testing antennas in different frequency bands, adjustments to the position and angle of the reflector panel may be necessary to optimize test results. However, the existing installation methods make the adjustment of the reflector panel difficult, hindering its quick and accurate adjustment to the required position and angle, thus affecting testing efficiency and accuracy.

[0005] Therefore, we have made improvements to this and proposed a multi-band compatible compact field antenna test system. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] 1. By setting up a connecting mechanism, slide rail and moving block, and driving the hydraulic rod, the angle of the reflector panel can be adjusted in conjunction with the fixed rod.

A connecting plate 502 is hinged to the other end of the fixing rod 501, and an installation frame 503 is connected to one side of the connecting plate 502. The installation frame 503 is fixedly installed on the back of the reflective panel 4. A slide rail 10 is fixedly installed on the upper surface of the base plate 1, and a movable block 11 is slidably connected to the outside of the slide rail 10. The fixed column 3 is fixedly installed on the upper surface of the movable block 11.

[0035] In this embodiment: the base plate 1 serves as the system base, integrating the feed antenna 2 and the reflector panel 4 adjustment module. The reflector panel 4 is connected to the fixed column 3 through the connecting mechanism 5. The hinge structure of the fixed rod 501 and the connecting plate 502, combined with the extension and retraction of the hydraulic rod 504, can precisely control the pitch angle of the reflector panel. Combined with the linear movement of the slide rail 10 and the moving block 11, the position of the reflector panel in the horizontal direction can be adjusted. The dual adjustment mechanism can be adjusted according to electromagnetic waves of different frequency bands to adapt to different antenna frequency bands.

[0036] refer to Figure 1 and Figure 2 Based on the above embodiments, in order to adjust the angle of the reflective panel 4, this embodiment provides the following design:

[0037] In a preferred embodiment, a hydraulic rod 504 is provided on one side surface of the fixed column 3 above the fixed rod 501, and the hydraulic rod 504 is connected to the fixed column 3 by a hinge connection, and the other end of the hydraulic rod 504 is hinged to the connecting plate 502.

[0038] In this embodiment, the hydraulic rod 504 adopts a double-hinged installation method.

[0039] refer to Figure 2 and Figure 3 Based on the above embodiments, in order to adapt to different antenna frequency bands and facilitate the replacement of different reflective panels 4, this embodiment provides the following design:

[0040] In a preferred embodiment, the mounting mechanism 6 includes a mounting block 601, and the mounting block 601 is connected to the mounting frame 503 by a snap-fit ​​connection, and the connecting plate 502 and the mounting frame 503 form a snap-fit ​​structure.

[0043] In this embodiment: In the grooves 602 symmetrically opened on both sides of the mounting block 601, the stop block 603 is kept in an outwardly extended state under the preload of the spring 606. The locking block 604 at its end engages with the locking grooves 605 on both sides of the mounting frame 503. When an external force is applied to press the stop block 603, the spring 606 is compressed, and the locking block 604 slides out of the locking groove 605 along the guide slope of the groove 602, thus releasing the lock and making disassembly easier.

[0044] refer to Figure 1 and Figure 4 Based on the above embodiments, in order to better clamp and fix the electromagnetic wave detection device, this embodiment provides the following design:

[0045] In a preferred embodiment, the clamping mechanism 9 includes a slider 901, and two sliders 901 are provided. Both sliders 901 are slidably connected inside the fixed frame 8.

[0046] In this embodiment: two sliders 901 are symmetrically distributed on the bidirectional threaded rod 904 inside the fixed frame 8, and move synchronously in opposite directions along the guide rail under the drive of the motor 905 to clamp the testing equipment. The rubber pad 903 covering the surface of the clamping plate 902 is made of nitrile rubber, which can effectively disperse pressure and avoid damage to the surface of the equipment;

[0047] When used in conjunction with the electric lifting rod 7, the testing equipment can be adjusted to different heights after the reflector plate 4 is adjusted, making the test more accurate.

[0048] In a preferred embodiment, a threaded rod 904 is rotatably connected inside the fixed frame 8, and the thread directions at both ends of the threaded rod 904 are opposite.

[0049] In this embodiment, the threaded rod 904 adopts a two-section reverse thread structure. When the motor 905 drives it to rotate, the two sliders 901 move synchronously in opposite directions on the guide rail of the fixed frame 8, thereby driving the clamping plate 902 to move and clamp the testing equipment.

[0050] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0051] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
