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.](https://drbulja.com/wp-content/uploads/2023/03/fig-1-topology-of-the-ec-based-aperture-coupled-reflectarray-unit-cell-not-to-scale.jpg)
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.
