The deployable space reflector antenna "E.V.M." comprises a tensioned frame and a deployable dome frame attached to the tensioned frame by means of connection joints at the outside of its periphery. The tensioned frame and the deployable dome frame create approximated surface of the entire reflector of the reflector antenna, whereto the reflector is attached. The approximated surface forms symmetrical and dissymetrical structures of offset reflectors having circular, oval, or polygonal outlines in plan. The tensioned frame is attached to the deployable rim by means of fastening joints and movable joint, or by movable joints solely. The deployable dome frame is connected to the deployable rim by means of fixed joints, movable joints, and/or the tensioned frame. In the process of being deployed, sizes of opposite contours of the deployable rim are equal or differ from one another by variable or constant value. The deployable rim is provided with a local deployment synchronization mechanism, local deployment fixation mechanism, and power-mechanical deployment system. In addition, the tensioned frame is provided with a common deployment stabilization system and common deployment orientation system.
