NON-METALLIC CYLINDERS FOR ELECTROMAGNETIC COMPATIBILITY TEST, TURNING ANGLE ADJUSTABLE ANTENNA DEVICE AND SYSTEM

摘要

There are provided a non-metallic cylinder for electromagnetic compatibility testing, a rotational angle adjustable antenna device, and a rotational angle adjustable antenna system. The rotational angle-adjustable antenna device provided by the present disclosure includes a non-metallic cylinder, a first adapter, and an antenna; the antenna is mounted in the first mounting hole with an outwardly disposed rotary sleeve, wherein at least one end of the antenna extends from the first mounting hole; the first adapter is further provided with a second mounting hole, the first piston rod of the non-metallic cylinder being disposed in the empty slot of the first adapter after having passed through the end cap of the non-metallic cylinder, second mounting hole of the first adapter; the first piston rod of the non-metallic cylinder is connected to the rotary sleeve, whereby the first piston rod can turn the antenna in the range of 0-90 °. Not only do technical solutions provided by the present disclosure have a simple operation principle, ease of operation and high reliability, but also realize positioning of the antenna in a multi-dimensional space by controlling a horizontal tilt angle and a rotational angle of the antenna.
