Reconfigurable antenna reflector

摘要

The reflector (10) has a set of coupling units (13) for connecting a rigid support (11) and a deformable membrane (12), where the units are distributed on a surface of the membrane. The units include finger ball connections (14, 15) connected to the support and the membrane. Each coupling unit includes a linear actuator (16) comprising a rotary motor (20) and a screw (21) and a nut (22) assembly connected to the connections. The actuator generates translation movement in an operational configuration to allow deformation of the membrane. The membrane is not fixed to periphery of the support.
