Abstract :
This paper addresses the design of a broadband reflectarray which takes advantage of the introduction of a suitable non-conventional shape radiating element to assure a large gain bandwidth. The element shape presents sufficient degrees of freedom to compensate the frequency variation of the differential spatial phase delay even when single-layer printed patches are employed.
