Abstract: In this invention a patch antenna and a reflect-array based on Electro-Chromic (EC) material is disclosed. The basic structure of the reflect-array unit cell is shown in Fig. 1 and the designed reflect-array operating at 300 GHz using the unit cell of Fig. 1 is shown in Fig. 2.

Fig. 1 Topology of the EC- based aperture- coupled reflectarray unit cell (not to scale), (a) front view and (b) side view.

The substrate for the patch can be any suitable dielectric such as SiO2 or BCB. The delay line is etched in the isolation layer, however, it is shown as a separate entity. The isolation layer can be any suitable dielectric such as SiO2 , SiN, BCB, to name but a few.
