Problems solved by technology

[0003] When using an open test site or an anechoic chamber for product electromagnetic compatibility testing, it is necessary to lift or rotate the antenna to change the angle of the antenna so that the test distance from the object under test to the antenna remains at a constant value; and different objects under test The volume of the antenna is different, so the distance from the antenna to the object to be measured is also different. If the existing antenna bracket is used, the distance from the antenna bracket to the object to be measured needs to be moved as a whole to a fixed value, which is inconvenient to use, and each time the operator manually Positioning the antenna bracket is prone to improper positioning and affects the accuracy of the test
[0004] In addition, the currently commonly used antenna mounts are electric, and the motor will generate large electromagnetic disturbances during the test, which will interfere with the test signals sent and received by the antenna and affect the effect of the electromagnetic compatibility test of the product.

Abstract

The invention provides an antenna frame and an antenna position control system. The antenna frame provided by the invention comprises an antenna frame body, a connecting arm connected with the antenna frame body, a connecting piece fixedly connected with the connecting arm, and an antenna and a nonmetal cylinder which are arranged on the connecting piece, wherein the nonmetal cylinder can drive the antenna to perform 0-90-degree rotation. The antenna frame and the antenna position control system provided by the invention have the advantages of convenient operation and accurate positioning, can also adjust the position of the antenna frame in an X-axis direction, a Y-axis direction and a Z-axis direction, at the same time, can also control the horizontal pitch angle of the antenna and the rotation angle of the antenna, realize positioning of the antenna in multi-dimension space, and improve the applicability of the antenna frame and the antenna position control system accordingly.

Description

technical field [0001] The invention relates to supporting equipment for electromagnetic compatibility testing, in particular to an antenna frame and an antenna position control system. Background technique [0002] With the rapid development of society and economy, people 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. [0003] When using an open test site or an anechoic chamber for product electromagnetic compatibility testing, it is necessary to lift or rotate the antenna to change the angle of the antenna so that the test distance from the object under test to the antenna remains at a constant value; and different objects under test The volume of the antenna is different, so the distance from the antenna to the object to be measured is also different. If the existing antenna bracket is used, the ...
