Problems solved by technology

[0002] 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; however, the commonly used antenna driving equipment is electric, and the motor will generate a large external force 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.

Abstract

The invention provides a non-metallic cylinder, an antenna device with adjustable rotation angle and a system for electromagnetic compatibility testing. The antenna device with adjustable rotation angle provided by the present invention includes a non-metallic cylinder, a first connecting piece, and an antenna; the antenna sleeve is provided with a rotating sleeve and then loaded in the first mounting hole of the connecting piece, and at least one end of the antenna extends out of the first mounting hole ; The first connector is also provided with a second mounting hole, the first piston rod of the non-metallic cylinder passes through the end cover of the non-metallic cylinder and the second mounting hole of the first connector, and is accommodated in the second mounting hole. In a hollow slot of a connecting piece; the first piston rod of the non-metallic cylinder is connected with the rotating sleeve to drive the antenna to rotate by 0-90°. The technical solution provided by the present invention not only has simple working principle, convenient operation and high reliability, but also realizes multi-dimensional spatial positioning of the antenna by controlling the rotation angle of the antenna and adjusting the pitch angle of the antenna.
