The main objective for this research is to study tungsten-doped vanadium dioxide (WVO2) phase change thin films. The (0.8% ratio of W) tungsten doped vanadium dioxide (WVO2) thin films were fabricated and tested. The tungsten doping shifted the transition temperature closer to room temperature, compared to 68C in undoped VO2. For this research, a coplanar waveguide (CPW) bowtie patch antenna was integrated with WVO2 thin films and the resonant frequency of the antenna can be shifted from 6.953 GHz at low temperature (20°C) to 6.538 GHz in mid temperature range (35°C) and then made inactive in high temperature range (50°C). The overall size of the CPW bowtie patch antenna is 6.45mm×6mm and the substrate of the antenna is sapphire.
