METHOD OF MAKING LARGE UNFURLABLE DOUBLE-REFLECTOR ANTENNA FOR SPACECRAFT Russian patent published in 2012 - IPC H01Q15/00 

FIELD: physics.

SUBSTANCE: method of making said antenna involves an operation for assembling its main parabolic reflector by unfurling sections of reflecting surfaces made from rigid size-stable material and placing a hyperbolic subdish on support arms near the focus of the main reflector, taking ground test measurements of radio characteristics of the antenna, wherein during ground tests, a ground version of the subdish is placed on size-stable support arms, the hyperbolic surface of the subdish being matched with the parabolic surface of the main reflector in ground temperature conditions, and after ground tests, the ground version of the radiator is dismantled and an orbital version of the subdish is placed on the size-stable support arms, the hyperbolic surface of said subdish being matched with the parabolic surface of the main reflector at temperatures in orbital conditions.

EFFECT: high-quality manufacturing of the antenna.
