An inflatable parabolic reflector antenna - Its realisation and electrical predictions

Results of investigations are presented for the potential electrical performances of an inflatable reflector antenna (prime-focus) illuminated by a three frequency coaxial feed. The feed has been deigned and tested, the reflector has been folded and deployed and assessed for its surface accuracy. The measured reflector surface data have been red into a physical optics program, in which the feed patterns as measured have been inserted also. Secundary pattern performances have been derived.
