This paper presents a dual-band single layer printed
reflectarray antenna with closely separated frequency bands
centered at 12 and 14 GHz. The novel unit cell, with which the
antenna has been designed, consists of a printed cross-dipole and
a split ring element mounted on the same substrate, providing the
antenna with dual polarization capability at both bands. The
antenna is composed of 17 × 17 elements printed on a square
plate with area of 20 × 20 cm2. In order to facilitate the
simulations, the antenna has been designed as center-fed
configuration, having the beam direction at broadside at both
frequencies. However, the antenna can be designed to have
arbitrary beam shapes at each frequency which makes it an
attractive option to be employed in satellite communication
