LIMITED-POINTING ANTENNA POSITIONING DEVICE Russian patent published in 2004 - IPC

FIELD: antenna structures; developing limited-pointing beam antennas.

SUBSTANCE: proposed antenna positioning device with limited pointing sector has supporting structure, articulated attachment joint made in the form of attachment joint of antenna and disposed on top of supporting structure, two pushing actuators each hinged on one end to supporting structure and on other end eccentrically secured on antenna relative to axis of revolution; antenna attachment joint is made in the form of cardan joint whose flanges are fixed in position on antenna and on supporting structure, respectively, and each pushing actuator is eccentrically mounted on antenna relative to axes of revolution of cardan joint, these axes of revolution being aligned with azimuth and elevation axes of revolution of antenna; pushing actuators are coupled with antenna and supporting structure through cardan joints.

EFFECT: simplified design of antenna revolving part, reduced cost of its positioning device.
