A reflectarray with independently controllable beam is proposed for the fifth-generation (5G) communication systems in this letter. A unit cell of the reflectarray is composed of an asymmetrical crossed-dipole element to realize dual-polarized operation. The cross-dipole element is printed by a transparent conductive film on an optically transparent substrate. In order to validate its performance, a 20 × 10-element (100 mm × 50 mm) reflectarray operating at 28 GHz is designed and analyzed numerically. Simulation results demonstrate that the reflectarray can independently control dual-polarized scattering beams and produce expected shaped radiation patterns.
