Reconfigurable U-Shaped Microwave Resonator for the Construction of a Hydrogen Sensor

This paper describes the design, parameter optimization and simulation of a resonant device using the CST Studio Suite for the development of a sensor capable of detecting hydrogen at microwave frequencies. The device is reconfigurable as it comprises a U-shaped resonator that can slide relative to a static stripline. As a result of this strategy, it is possible to investigate a configuration that yields the best response for hydrogen detection, taking into account the frequency variation and insertion loss induced by hydrogen gas on the palladium present in the device.
