FIELD: space engineering; artificial earth satellites or interplanetary probes. SUBSTANCE: proposed antenna reflector 1 for space vehicle 14 capable of sustaining elastic strain and of turning from folded to unfolded condition and vice versa at least partially under its inherent elasticity incorporates following characteristic features. Reflector 1 is divided into two parts 1A, 1B by slit with edges 5A, 5B facing each other. In folded condition of reflector 1 edges 5A, 5B of its parts are relatively displacing (in 11) so that protruding peripheral part 1S of reflector 1 approaches longitudinal edge 14S of mentioned space vehicle. EFFECT: improved dynamic equilibrium and reduced level of reflector vibrations with provision for enlarging its size. 15 cl, 15 dwg
