Abstract

We present the design, simulation and fabrication of innovative tunable band stop filters realized using switching devices based on the fast, reversible Metal-Insulator Transition of vanadium dioxide thin films. The filters are designed to operate in the 11-13 GHz frequency range and consists in a transmission line coupled with four U-shaped resonators. We developed two types of tunable filters based on VO2 switches integration namely a ldquoswitchable stop band filterrdquo for which the rejection band can be switched on and off and a ldquodiscrete tunable stop-band filterrdquo for which the width and position of the stopband can be discretely tuned.
