Abstract :
The objective of this work is the design of a 32×32 element X-band reflectarray, in which the re-radiated elements have no conventional shape and enough degrees of freedom to compensate both the spatial and frequency phase variation of the re-radiated field. In particular, here we focus on a re-radiating element consisting in two concentric square rings in which two different and quite independent geometric parameters are varied.
