FOUR-MIRROR ANTENNA WITH MECHANICAL SCANNING Russian patent published in 2024 - IPC H01Q3/08 H01Q19/18 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna technology, in particular to antennas with a fixed feed and a system of re-reflecting mirrors built on the periscope principle. Result is achieved by the fact that a four-mirror antenna with mechanical scanning is provided, comprising a system of rotary mirrors, where the first mirror is located at an angle to the axis of rotation in the horizontal plane, and second mirror is located at an angle to axis of rotation in vertical plane, drives of rotation of mirrors in horizontal plane and vertical plane, fixed feed, characterized in that the feed is made in the form of a multi-element waveguide antenna array, to each of the elements of which, using a separate waveguide path, microwave power is supplied from the transmitting device, on the second bracket, the third mirror and the fourth mirror are installed with the possibility of forming a narrow beam when they are successively irradiated by the field reflected from the second mirror, and the second mirror is configured to form a wide beam when the third mirror is taken out of the working position.

EFFECT: high radiated power and possibility of changing the shape of the directional pattern of the antenna, in particular, formation of a narrow or wide beam.
