FIELD: antenna devices.
SUBSTANCE: invention relates to antenna devices with mechanical scanning and can be used on moving objects. In an antenna device with an electromechanical drive, the shafts of azimuth and elevation rotation located coaxially are set in motion by different motors independently of each other. On the basis, rigidly connected with the shaft of azimuth rotation, there is a carriage that performs reciprocating movements under the action of an eccentric installed at the end of the shaft of elevation rotation. A suspension is installed on the base with the possibility of rotation around the fixing axis under the action of the carriage. A holder is installed on the suspension by means of a bearing with a bracket fixed on it with the possibility of rotation around the fixing axis, having toothed sectors interacting with gears fixed on the housing, while the movable reflector is rigidly mounted on the holder.
EFFECT: invention provides the ability to view the target area at a high speed according to the spiral law with the ability to control the trajectory of the scanning beam in the process of operation, as well as expanding the scope of application due to the possibility of building an antenna with a rotation of the polarization plane.
