ABSTRACT:
The invention is an electromagnetic wave reflector for an antenna and its production method. The wave reflector comprises a rigid curved support provided with a convex front face coated with a heat-insulating paint, a metal fabric suitable for reflecting the electromagnetic waves and covering the paint, hook and loop strip type fixing means secured to the rear face of the support ensuring that the fabric is maintained on the support, and a thermal extra-insulating material situated on the entire rear face of the support, said extra-insulation material being kept in place by adhesive polyimide strips.
