Abstract

The invention provides a nonmetal air cylinder for an electromagnetic compatibility test and an antenna device and system with the adjustable rotation angle. The antenna device with the adjustable rotation angle comprises a nonmetal air cylinder, a first connecting piece and an antenna, wherein the antenna is sleeved with a rotary sleeve and then loaded into a first installation hole of the connecting piece and at least one end of the antenna extends out of the first installation hole; the first connecting piece is further provided with a second installation hole, a first piston rod of the nonmetal air cylinder penetrates to an end cover of the nonmetal air cylinder and the second installation hole of the first connecting piece in sequence and then is contained in a groove of the first connecting piece; and the first piston rod of the nonmetal air cylinder is connected with the rotary sleeve to drive the antenna to rotate from 0 degree to 90 degrees. By the adoption of the technical scheme, the work principle is simple, operation is convenient, reliability is high, and antenna multi-dimensional space localization can be achieved by controlling the rotation angle of the antenna and adjusting the pitch angle of the antenna.

Description

technical field [0001] The invention relates to supporting equipment for electromagnetic compatibility testing, in particular to a non-metallic cylinder, an antenna device with adjustable rotation angle and a system for electromagnetic compatibility testing. Background technique [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 caused by the antenna interferes with the test signal sent and received by the antenna, which affects the effect of the product electromagnetic compatibility test. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a non-metallic cylinder, an antenna device with adjustable rotation angl...
