Abstract :
This paper demonstrates that cross polarization in offset reflectarrays can be significantly reduced by properly adjusting the separation between layers and the patch dimensions in a three-layer reflectarray. The technique has been applied to design a 1-m reflectarray for a South American coverage seen from a satellite located at 61deg west stationary orbit.
