Abstract :
The electromechanical tune method for microwave filters based on coplanar lines are proposed. The simulation of the proposed filter structure was made by finite differences method in the time domain. This method allows tuning for resonance frequency about 80 percents with the air gap between the substrate and the signal electrode width about 50 μm. The proposed method can be realized with MEMS technology and piezoelectric actuators.
