A novel dual-band reflectarray for beam control of reflected waves at GSM and LTE bands is proposed in this paper. The reflectarray is constructed with two substrates separated at a distance form. Consisting of square ring and four stubs, the FSS cell element has the dual-band property for the changes of current distribution. A crossed-dipole element is printed on the surface of another substrate, and the progressive phase distribution is achieved for the reflected wave by adjusting the resonant length of the crossed-dipole element. The reflectarray can independently control the direction of both horizontally and vertically polarized reflect beams at two resonant frequencies. A reflectarray comprising 7 by 5 elements with operation at 1.7 GHz and 2.7 GHz is studied and measured, which can be applied in the GSM and LTE communication systems.
