An antenna reflector for a spacecraft, produced in an elastically deformable way and capable of changing from a folded position to a deployed position at least partly under the action of its own elasticity. The reflector includes at least one fold line, the general direction of which is at least approximately parallel to the axis of the casing and about which said reflector is folded in its folded state.

Elastically deformable antenna reflector for a spacecraft

An antenna reflector for a spacecraft is elastically deformable so as to be capable of changing from a folded position, when inside the spacecraft, to a deployed position, outside the spacecraft, at least partly under the action of its own elasticity. The reflector is separated into at least two parts by first opposing slot edges forming a crossing slot, so that in the folded position, the first opposing edges move with respect to each other so as to allow a protruding peripheral part of the reflector to be arranged closer to a longitudinal end of the spacecraft with damaging any portion of the reflector. In one embodiment, the two parts may be further separated by a radial slot which is arranged substantially orthogonal to the crossing slot.
