FIELD: elastically deformable antenna reflector for space vehicle such as an artificial satellite or an automatic interplanetary station; the invention also concerns a space vehicle provided at least with a single such reflector. SUBSTANCE: antenna reflector 1 has a radial slot. In the rolled up position of reflector 1 the edges (2A, 2B) of the radial slot positioned opposite each other are put over each other in such a way so that the reflector would take at least approximately a tapered shape that allows its installation in shell 7 vertically above space vehicle 8. EFFECT: enhanced dimensions of the reflector. 7 cl, 6 dwg
