  • Reconfigurable Dual Reflector for a Realistic Mission Scenario in Ku Band | TICRA
    Scenario in Ku Band Abstract The possibility of employing the same spacecraft at several orbital locations changing the coverage region and compensating for varying weather conditions are the main reasons why reconfigurable antennas for contoured beam generation can provide significant advantages in satellite communications Though extremely attractive in terms of cost and manufacturing shaped reflectors lack so far the capability of being reconfigured in orbit while this feature can be
