[0002] In wireless communication testing within a reverberation chamber, the antenna's position significantly impacts the test results. Since reverberation chambers are typically small, the antenna is usually immovable. Traditionally, repositioning the antenna requires manual intervention within the chamber, which not only interrupts the wireless communication test but also necessitates repeated adjustments, hindering the testing process and reducing efficiency. Therefore, automatically controlling antenna movement within a reverberation chamber is a pressing issue that needs to be addressed. Utility Model Content

Detailed Implementation
[0016] like Figure 1 As shown, this utility model provides an antenna movement control device for a reverberation shielding room, used for installation within a reverberation shielding room. It includes: a planar frame 1, on which a first-direction support plate 2 and a second-direction support plate 3 are mounted. The first-direction support plate 2 has an antenna mounting block 4 and a first-direction movement mechanism, which drives the antenna mounting block 4 to move along a first direction. The second-direction support plate 3 has a second-direction movement mechanism connected to the first-direction support plate 2, which drives the first-direction support plate 2 to move along a second direction. The drive control terminals of both the first and second-direction movement mechanisms are connected to external control equipment to receive first-direction movement control signals and second-direction movement control signals, respectively. Specifically, the drive control terminals of both the first and second-direction movement mechanisms are connected to external control equipment via cables through the shielding room's filter port.
[0017] The first direction support plate 2 is set in the vertical direction, and the second direction support plate 3 is set in the horizontal direction.
[0018] like Figure 2 As shown, the first direction moving mechanism adopts a lead screw linear motion mechanism, including a first stepper motor 5 and a first lead screw 6. The first lead screw 6 is connected to the output shaft of the first stepper motor 5 through a coupling or other feasible connection method such as a key connection. The first lead screw 6 is rotatably supported on the first support unit 7. The first lead screw 6 is connected to the first slide block 8, and the antenna mounting block 4 is mounted on the first slide block 8. The first stepper motor 5 is used to drive the first lead screw 6 to rotate and drive the first slide block 8 to move in the first direction.
[0019] A first guide rail is provided on the first direction support plate 2, and the first slide 8 moves along the first guide rail in the first direction. The first guide rail can be a linear guide rail, which provides support and high-precision linear guidance for the first slide 8.
[0020] like Figure 3 As shown, the second direction moving mechanism adopts a lead screw linear motion mechanism, including a second stepper motor 9 and a second lead screw 10. The second lead screw 10 is connected to the output shaft of the second stepper motor 9 through a coupling or other feasible connection method such as a key connection. The second lead screw 10 is rotatably supported on the second support unit 11. The second lead screw 10 is connected to the second slide 12, and the first direction support plate 2 is installed on the second slide 12. The second stepper motor 9 is used to drive the second lead screw 10 to rotate and drive the second slide 12 to move in the first direction, thereby driving the first direction support plate 2 to move in the second direction.
[0021] A second guide rail is provided on the second direction support plate 3, and the second slide 12 moves along the second guide rail in the second direction. The second guide rail can also be a linear guide rail, which provides support and high-precision linear guidance for the second slide 12.
[0022] The planar frame 1 is made of aluminum alloy, and the second direction support plate 3 is fixed on the planar frame 1.
[0023] When the tester is outside the reverberation shield and needs to move the antenna vertically, the computer sends a first direction movement control signal to the first stepper motor 5 inside the reverberation shield. After receiving the first direction movement control signal, the first stepper motor 5 drives the first lead screw 6 to rotate and drives the first slide block 8 to move vertically. The movement of the first slide block 8 then drives the antenna mounting block 4 and the antenna on the antenna mounting block 4 to move, thereby realizing the vertical movement control of the antenna. When it is necessary to move the antenna in the horizontal direction, the computer sends a second direction movement control signal to the second stepper motor 9 in the reverberation shielding room. After receiving the second direction movement control signal, the second stepper motor 9 drives the second lead screw 10 to rotate and drives the second slide block 12 to move in the horizontal direction. The movement of the second slide block 12 then drives the first direction support plate 2 and the antenna on the antenna mounting block 4 on the first direction support plate 2 to move, thereby realizing the movement control of the antenna in the horizontal direction. When it is necessary to move the antenna in any direction within the plane, first move the antenna in the horizontal direction, and then move the antenna in the vertical direction, thereby achieving movement control of the antenna in any direction within the plane.
[0024] This invention enables personnel to control the movement of the antenna inside the shielded room, improving testing efficiency. By establishing vertical and horizontal movement mechanisms, the position of the antenna can be precisely controlled.

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 scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope defined in the claims.
