Popis:	This paper presents a single-layer single-sided dual-band MEMS reconfigurable reflectarray unit cell operating at 12 and 14 GHz. Each operating bands can continuously and independently be tuned using a pair of MEMS varactors at vertical and horizontal polarizations. A capacitance ratio of 2 provides more than 310 degree dynamic phase range with a very low loss. Therefore, the resulting reflectarray composed of this unit cell will have two beams that can independently be scanned at different operating frequencies and polarizations.
