Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0033] See attached Figure 1-6 , shown is a wireless test component with an adjustable interference antenna, the wireless test component includes a storage platform part 1 and an antenna part 2; the storage platform part 1 includes a base 100, a chassis 101 and a storage turntable 103102, the chassis 101 can be installed on the base 100 for horizontal linear movement, and the storage turntable 103102 can be installed on the chassis 101 for horizontal rotation; the antenna part 2 includes a base 20, a lifting member 21, a steering plate 22 and an antenna module 23, the lifting member 21 can be installed on the base 20 for up and down movement, the steering plate 22 can be rotatably installed on the lifting member 21, and the antenna module 23 is installed on the steering plate 22.

[0034] The antenna module 23 is installed on the steering plate 22, and the steering plate 22 rotates on the lifting member 21 to adjust the angle of the antenna module 23. At the same time, the lifting member 21 is lifted and lowered along the base 20 to adjust the height of the antenna module 23; the storage turntable 103102 of the storage table part 1 is used to place the product under test, and the storage turntable 103102 rotates along the chassis 101 to adjust the angle of the product under test, and the chassis 101 moves linearly compared to the base 100, thereby adjusting the position of the product under test.
