Influence of topological parameters of MEMS-enabled tunable microstrip resonators on their characteristics

Article is devoted to the resonant elements topological parameters optimization for maximum resonance frequency tuning efficiency. Stub and ring resonators based on microstrip lines are presented. The maximum length of the movable stub resonator part with micromechanical tuning was determined. Criteria for optimal ring resonator width were obtained. Such recommendations for stub and ring resonators increasing the maximum frequency tuning limit and allowing to avoid distortion in resonator's transmission coefficient.
