ANTENNA DEVICE Russian patent published in 2008 - IPC H01Q3/08 

FIELD: electrical engineering.

SUBSTANCE: invention consists in that the antenna device incorporates a fixed dish aerial, a reflector arranged at an angle to the said dish aerial, a reflector azimuth scanning and rotation drive, an azimuth rotation output hollow shaft housing coaxially arranged second shaft with a cam located on its end face to interact with the slot of a carriage fitted on the first shaft to reciprocate in the plane perpendicular to the shaft common axis and furnished with a rack interacting with a ratchet latch rigidly linked to the reflector fitted on the first shaft to swing relative to the axis perpendicular to the shafts common axis. Invention novelty consists in that the device incorporates an angle transducer linked to both shafts and outputting the data on the reflector azimuth rotation and inclination defined from the proposed formulae.

EFFECT: smaller weight and sizes and lower manufacturing costs.
