Axially symmetric dual-reflectarray antennas

An axially symmetric dual-reflectarray antenna is proposed. A main reflectarray is designed to mimic a paraboloidal main reflector, and a sub-reflectarray is designed to mimic a hyperboloidal or an ellipsoidal sub-reflector. The dual-reflectarray antenna is more compact than the conventional curved...

Zusammenfassung:	An axially symmetric dual-reflectarray antenna is proposed. A main reflectarray is designed to mimic a paraboloidal main reflector, and a sub-reflectarray is designed to mimic a hyperboloidal or an ellipsoidal sub-reflector. The dual-reflectarray antenna is more compact than the conventional curved dual reflector. The dual-reflectarray antenna is designed at W-band and compared with its equivalent Cassegrain antenna.
