Abstract
The design of microstrip reflectarrays requires the knowledge of the relation between the phase of the re-radiated field and the geometrical and electrical characteristics of the radiating elements. In this paper this parameter has been evaluated using a simplified approach based on a commercial simulator. The method uses the simulator to characterize the single radiating cell and evaluates the contribution of the finite ground plane with the physical optics approximation. The proposed design technique has been experimentally validated. Furthermore a new approach for beam steering in reflectarray applications is here introduced. Both active and passive reflectarrays have been designed and tested.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
