In this paper, a folded reflectarray antenna (FRA) is developed using crossed-dipole based reflector. By the Pancharatnam–Berry phase theory, it theoretically demonstrated that reflector capable of providing both 90° polarization conversion and compensation for linearly polarized incident waves. Due to negligible mutual interaction between two orthogonally crossed dipoles, reflection phases waves with polarizations along dipoles can be controlled independently, making convenient at same...
