FOLDING RADIO FREQUENCY MEMBRANE ANTENNA Russian patent published in 2021 - IPC B64G1/22 

FIELD: electronics.

SUBSTANCE: invention relates to transformable, primarily large-sized constructions. Proposed antenna is comprised of a collector (combined with a space vehicle (SV)) and a load-bearing structure with a toroid (inflatable) outer frame and a celled net hoisted thereon. The SV is connected to the frame with three (or more) connectors. Tension ties ("strops" between nodes of the net and the SV) are attached to the net which when unfolded cause bending of the celled net which determine the required shape of the reflector fixated on the tension ties between the frame and the SV. The reflector may contain membranes wherein each of them is connected to the adjacent tension ties. Proposed are the variants of realization of uncoiling anntennae.

EFFECT: reduction of the volume taken by a large-sized antenna in folded configuration.
