MULTIBEAM MIRROR ANTENNA Russian patent published in 2021 - IPC H01Q15/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering, particularly to mirror antennas, and is intended for use in on-board antennae of artificial Earth satellites to provide multi-beam coverage of Earth's surface in microwave range. Technical result is achieved due to the fact that in a multi-beam mirror antenna consisting of an array of irradiators located on an offset scheme and a focusing system, said focusing system is in form of tripod, which includes at least three parabolic reflector, and the array of irradiators contains at least three subarrays corresponding to their parabolic reflector.

EFFECT: technical result is an increase in the surface area of the antenna, which in turn increases the antenna gain, reduces the level of intersection of adjacent beams, more efficient use of the surface of the focusing system, minimizes angular separation of beams from the focal axis of the parabolic reflector.
