Abstract :
A circularly polarised millimetre-wave reflectarray antenna based on cross-slots of varying length couple through a patch as the cell element is introduced. Far-field radiation pattern, gain and axial ratio are presented and compared with a reflectarray that employs cross-dipoles as its cell element.
