Abstract

This research reports the finite element modeling (FEM) simulation of ZnO based film bulk acoustic resonator (FBAR). The design, FEM simulation, and analysis of the FBAR is covered, which is needful for the development of RF filters and duplexers. Different electrical parameters of FBAR such as impedance, phase, quality factor, and total stored electromechanical energy have been simulated with respect to frequency using COMSOL Multiphysics 4.4 software. The back cavity based FBAR structure is used for the confinement of the acoustic energy within the piezoelectric layer. The resonant frequency , anti-resonant , bandwidth, and effective coupling factor of the simulated resonator are 1.4 GHz and 1.441 GHz, 41 MHz, and 7.01%, respectively.
