Double layer patch element, which is added to an additional patch above dielectric layer, using nematic liquid crystal for 100 GHz band electrically tunable reflectarray is proposed. The maximum phase change is achieved to 360 degrees and the frequency range of over 360 degrees is between 90.5 GHz and 120 GHz. Phase change characteristics In this element are independent of the polarization of the incident wave and it is advantage for the application of the reflectarray.
