Embodiment Construction
[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0050] The overall test environment of the embodiment of the present invention is as figure 1 As shown, the mixing shielding chamber is equipped with two mechanical stirrers 101, 102 and a turntable 103, which can be rotated so that the antenna mounted on the turntable can rotate along X, Y and Z directions. Establish a three-dimensional rectangular coordinate system with the antenna itself. When the Z-axis of the antenna is placed vertically on the turntable and the turntable is turned, the antenna can complete the effect of rotating around the Z-axis. Similarly, when the Y-axis and X-axis of the antenna are placed on the turntable perpendicular to the turntable and the turntable is turned, the antenna Rotation effects around the Y and X axes can be achieved. Meanwhile, in the test environment, the load absorber 104, the antenna to be tested 105 and the cal...
