Abstract :
The design of a broadband reflectarray exploiting a non-conventional shape radiating element to assure a large gain bandwidth is proposed. The element shape presents sufficient degrees of freedom to compensate for the frequency variation of the differential spatial phase delay even when single-layer printed patches are employed.
