Abstract
A reconfigurable reflector for electromagnetic waves, comprising: a rigid support element () having a front surface (); an elastically deformable reflective membrane () lying over the front surface of said rigid support element; and a plurality of linear actuators () for deforming said reflective membrane by operating on predetermined points thereof; wherein said linear actuators are embedded within said rigid support element, and have shafts () protruding by the front surface thereof for operating on predetermined points of said elastically deformable reflective membrane. Preferably, the rigid support element comprises a reflector dish having a sandwich structure having a honeycomb core () made of CFRP or aluminum, in which the linear actuators are embedded by conventional potting techniques. Antenna system comprising such a reconfigurable reflector, possibly operating as a subreflector (SR), and spacecraft telecommunication.
