Active re-configurable multibeam reflector antenna for satellite application

Recent results on active multifeed Ka-band developments for satellite communication are presented. Basically, the active multifeed system is an array-fed, single-offset reflector antenna. The antenna array is fed by an active microstrip beamforming network based on a low temperature cofired ceramics substrate with monolithic microwave integrated circuit based phase and amplitude actuators. In this paper, the benefits of such a technology are shown as well as first project results.
