- Abstract: <jats:sec><jats:label /><jats:p>An approach to a design of tunable frequency‐selective surfaces (FSSs) for radio frequency (RF) domain based on vanadium dioxide (VO<jats:sub>2</jats:sub>) thin films is proposed. As an example, a thermally tunable annular slot FSS with integrated VO<jats:sub>2</jats:sub> switchable elements for C‐band of the RF domain is described. Switching is based on abrupt change of conductivity of the VO<jats:sub>2</jats:sub> film, initiated by heating from room temperature to a temperature of the metal–insulator phase transition of 44 °C. A tuning mechanism of the FSS allows continuous change of frequency response from room temperature state, where the FSS acts as a band‐pass filter, to high‐temperature state, where the FSS works as a reflector. In the process of tuning, a reflection coefficient at a central frequency of the filter can be increased from −26.4 dB up to −2.2 dB. The proposed approach can be used for the design of tunable FSS for applications that allow thermal control of the frequency response.</jats:p></jats:sec>
