DUAL-MIRROR ANTENNAS WITH MECHANICAL TARGETING Russian patent published in 2018 - IPC H01Q3/08 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment, in particular to antennas of space vehicles. Dual-mirror antenna with mechanical targeting contains a system of rotary mirrors, where the mirror of the counter reflector is located at an angle of 45° to the axis of rotation in the horizontal plane, and the mirror of the reflector is located at an angle to the axis of rotation in the vertical plane, a rotation drive of mirrors in a horizontal plane with an electric motor, a rotation drive of mirrors in a vertical plane with an electric motor, a polarizer is introduced into the waveguide path of the irradiator, the output of which is rigidly connected to the input of the irradiator, made in the form of a conical horn, whose axis coincides with the axis of the polarizer. In this case, with respect to the polarizer axis, the first bracket with a counter-reflector rigidly mounted on it rotates horizontally in the horizontal plane, which ensures that the antenna beam is aimed in a horizontal plane within the sector ±180°, a second bracket is mounted on the first bracket, allowing to provide removal of the reflector which is mounted on it and rotated by means of an electric motor, and to ensure that the beam of the antenna is aimed in a vertical plane within a sector of at least ±105°.

EFFECT: technical result consists in the possibility of providing the angular targeting sectors of the antenna by the elevation angle of at least ±105°.
