Document Type and Number:
WIPO Patent Application WO/2017/118358
Kind Code:
A1
Abstract:
A non-metal pneumatic cylinder for use in an electromagnetic compatibility test (01), an antenna device (001) having an adaptable angle of rotation, and a system (003). The antenna device (001) having the adaptable angle of rotation comprises a non-metal pneumatic cylinder (01), a first connection member (02), and an antenna (03). A rotational cover (31) is fit on the antenna and then installed in a first installation hole (23) of the connection member. At least one end of the antenna extends outward from the first installation hole. A second installation hole (24) is provided at the first connection member. A first piston rod (14) of the non-metal pneumatic cylinder sequentially passes through an end cap (12) of the non-metal pneumatic cylinder and the second installation hole of the first connection member, and is then accommodated in a chamber (22) of the first connection member. The first piston rod of the non-metal pneumatic cylinder is connected to the rotational cover to drive the antenna to rotate 0-90°. The technical solution is simple in operation principle, easy to operate, high in reliability, and can realize position limit of an antenna in a multi-dimensional space by controlling a rotation angle of the antenna and adjusting a tilt angle of the antenna.
