Specifically, a test component 12 is position-adjustably mounted on the suspension 11, and the test component 12 is used for OTA testing of the 5G base station antenna to be tested. It should be noted that OTA testing is an abbreviation for Over The Air, i.e., over-The-Air testing. The alignment assembly 13 is used to align the testing assembly 12, so that the position of the testing assembly 12 can be quickly aligned with the 5G base station antenna to be tested. Further, the sliding beam 121 is slidably mounted on the suspension 11, that is, the sliding beam 121 can slide on the suspension 11 along a straight line reciprocating in a specified direction. Further, the slider 122 is slidably mounted on the sliding beam 121, that is, the slider 122 can perform reciprocating linear sliding along the sliding beam 121. Wherein the sliding direction of the slider 122 with respect to the sliding beam 121 and the sliding direction of the sliding beam 121 with respect to the suspension 11 are perpendicular to each other. And the test antenna 123 is installed on the slider 122, so that the test antenna 123 can be adjusted in position along the X direction and the Y direction of the horizontal plane through the mutual cooperation of the suspension 11, the sliding beam 121 and the slider 122. Thus, when the test component 12 is installed in the shielding box of the OTA test device, the test antenna 123 can be adjusted to point to any position in the shielding box according to actual needs, so that the test antenna 123 can be accurately aligned with the 5G base station antenna to be tested.

Further, as shown in fig. 1, the alignment assembly 13 includes a sliding base 131, a swinging plate 132 and an alignment meter 133, the sliding base 131 is slidably disposed on the sliding beam 121, the sliding base 131 is fixedly connected to the sliding block 122, the swinging plate 132 is rotatably disposed on the sliding base 131, the alignment meter 133 is disposed on the swinging plate 132, and the swinging plate 132 is used for driving the alignment meter 133 to rotate, so that the alignment meter 133 is aligned with the test antenna 123.

The swing plate 132 is rotatably mounted on the sliding base 131, for example, one end of the swing plate 132 is mounted on the sliding base 131 through a rotating shaft, so that the swing plate 132 can rotate relative to the rotating shaft, and the alignment instrument 133 is mounted on the swing plate 132, so that the swing plate 132 can drive the alignment instrument 133 to rotate. Thus, when the swing plate 132 rotates downward to the bottom, the alignment device 133 and the test antenna 123 can be brought into alignment, that is, the alignment device 133 and the test antenna 123 are collinear. In this way, the position of the test antenna 123 can be quickly adjusted by the aligner 133 so that the test antenna 123 and the 5G base station antenna to be tested are aligned with each other. After the position adjustment is completed, the swing plate 132 is rotated, so that the alignment instrument 133 rotates to be away from the test antenna 123, thereby preventing the test antenna 123 from being blocked. Thus, the test antenna 123 can be quickly adjusted in position.

Therefore, the slider 122 and the test antenna 123 can be quickly positioned by the matching of the marking groove 1223 and the alignment hole 1222.

As shown in fig. 3, the testing assembly 12 preferably further includes a locking screw 124, the locking screw 124 is screwed with the sliding block 122, and the locking screw 124 abuts against the sliding beam 121.
