AMPLIFYING LENS FOR DOUBLE-REFLECTOR ANTENNA Russian patent published in 2014 - IPC H01Q15/02 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to antenna engineering, particularly large-diameter antennae and large parabolic reflectors, and can be used in fields where there is need to considerably increase antenna sensitivity for observing small-size sources. The engineering problem is increasing sensitivity of a double-reflector antenna for observing point sources without considerably increasing overall weight of the structure and enabling deployment of the structure in space. Said problem is solved by combining a double-reflector antenna with an additional amplifying lens, which is a truncated right circular cone whose diameter is greater than the diameter of the main parabolic reflector, the height is approximately 3 times shorter than the diameter of the main parabolic reflector, and a cone-shaped convergent mirror for the additional amplifying lens.

EFFECT: high information value of observation data by increasing antenna sensitivity in point source observation mode without considerably increasing overall weight of the antenna structure.
