Abstract :
This article presents a new approach to analyze a reflectarray antenna and calculate the phase shifts needed to generate a beam in a given direction. The method is used with a two layer reflectarray including local ports. Reactive loads on the rear panel allow a beam control. The method described combine full-wave simulation and analytical formulation to obtain both accuracy and versatility.
