Large deployable antenna for various space applications

The paper describes how an activity is going on for a design, development and realisation of a large 12-meter deployable reflector antenna for space applications. The reflector antenna system is subject of an ESA contract awarded to Alenia Spazio as a prime contractor. The Russian company NPO EGS is responsible as sub-contractor for an important element, which is the deployable reflector. Alenia has provided, together with ESA, instrumentation and testing expertises for assessment of passive intermodulation properties of the realised reflector, which is currently being prepared for environmental testing. Background knowledge was fed into the program from the Georgian antenna design, comparable to the one, which did fly on MIR station.
