Abstract :
The basic design equations for reflectarrays that emulate ellipsoidal and hyperboloidal sub-reflectors (hereafter referred to as sub-reflectarrays) are presented. Measurements performed on an example of the ellipsoidal type sub-reflectarray are described, showing the far-zone amplitude and phase patterns, in so doing validating the design equations.
