This paper describes a method to improve vibration isolation performance. The purpose of this research is to suppress the resonance without increasing the displacement transmissibility in the frequency region higher than the natural frequency of the plate-type support structure. Because it is impossible to be achieved with the viscous damping, we use hysteresis damping in this research. In this research, we use a method of amplifying the dielectric loss tangent of a piezoelectric element by using a negative capacitance circuit because the dielectric loss tangent of the piezoelectric element is categorized into the hysteresis damping. The effectiveness of the proposed method was verified through simulations and experiments.
