IN-SERVICE RECONFIGURABLE ANTENNA REFLECTOR

摘要

The present invention relates to an in-service reconfigurable antenna reflector (10) comprising a rigid support (11) and a membrane (12), deformable and having radio-electric reflectivity properties. According to the invention, the reflector comprises a plurality of coupling means (13) connecting the rigid support (11) and the membrane (12), comprising a first link of finger ball joint type (14) connected to the rigid support (11), and a second link of finger ball joint type (15) connected to the membrane (12). Each coupling means (13) furthermore comprises a linear actuator (16), comprising a rotary motor (20) and a screw (21) - nut (22) assembly, connected to the two links of finger ball joint type (14, 15), and able to generate, in an operational configuration, a translational motion allowing the deformation of the membrane (12).
