Antenna reflector has a reflector surface which forms a predetermined dish-like shape. The reflector surface includes an inner section which radially extends a first predetermined distance from a main dish axis. This inner section is immovably supported on a fixed backing structure. The reflector surface also includes an outer section comprising a deployable perimeter. A deployable support structure is comprised of a plurality of rib tips hingedly secured to the fixed backing structure, each having an elongated shape, and extending in a direction away from the main dish axis. The rib tips are configured to rotate on hinge members relative to the fixed backing structure from a first position in which the reflector antenna is made more compact for stowage, to a second position in which a diameter of the reflector surface is increased at a time of deployment.
