Problems solved by technology

When using an open test site or an anechoic chamber for product electromagnetic compatibility testing, it is necessary to vertically lift the antenna and change the polarization direction of the antenna; and the existing antenna towers are all electric, and the motor will generate a large external noise during the test. The electromagnetic disturbance of the antenna will interfere with the test signal sent and received by the antenna, which will affect the effect of the electromagnetic compatibility test of the product; at the same time, there are currently two types of antennas used for electromagnetic compatibility testing, namely low-frequency antennas and high-frequency antennas, and the existing antenna towers are generally It is only used for one type of antenna, and cannot be applied to two types of antennas separately

Embodiment Construction

[0053] figure 1 , figure 2 with image 3 It shows an antenna tower provided by an embodiment of the present invention, which is used to install a high-frequency antenna 740 and / or a low-frequency antenna 750 for electromagnetic compatibility testing. The antenna tower includes a tower base 100 and a wire vertically installed on the tower base 100 Rod 200. The antenna tower further includes a slider 400 slidably sleeved on the screw rod 200 , and a high-frequency antenna steering device 500 and a low-frequency antenna steering device 900 fixedly installed on the slider 400 .

[0054] The tower base 100 has a built-in driver (not shown in the figure) for driving the slider 400 to vertically ascend and descend along the screw rod 200;

[0055] Specifically, in this embodiment, an external thread is provided on the outer wall of the screw rod 200 , and a first fixing hole penetrating through the slider 400 is opened on the slider 400 . The thread corresponds to the internal t...

Abstract

The invention provides an antenna tower and a using method thereof. A high-frequency antenna (740) and / or a low-frequency antenna (750) for electromagnetic compatibility testing are arranged on the antenna tower. The antenna tower comprises a tower base (100) and a screw rod (200) vertically arranged on the tower base (100), and is characterized in that the antenna tower further comprises a high-frequency antenna steering device (500), a low-frequency antenna steering device (900) and a sliding block (400) sleeving in a sliding mode the screw rod (200); the tower base (100) is internally provided with an actuator for driving the sliding block (400) to vertically rise and fall along the screw rod (200); and the actuator is connected with a pneumatic motor. According to the antenna tower, interference of burr signals generated during the test of the motor on test signals sent and received by the antenna can be avoided, and the result of the electromagnetic compatibility testing of the product is accurate.

Description

technical field [0001] The invention relates to ancillary equipment for electromagnetic compatibility testing, in particular to an antenna tower for electromagnetic compatibility testing and a usage method thereof. Background technique [0002] With the rapid development of society and economy, people's awareness of environmental protection is gradually increasing, and they pay more and more attention to the electromagnetic compatibility of products. For products included in the scope of national compulsory product certification, electromagnetic compatibility testing has become a must-test item. When using an open test site or an anechoic chamber for product electromagnetic compatibility testing, it is necessary to vertically lift the antenna and change the polarization direction of the antenna; and the existing antenna towers are all electric, and the motor will generate a large external noise during the test. The electromagnetic disturbance of the antenna will interfere w...
