We have investigated impedance-loaded surface acoustic wave (SAW) sensor for structural health monitoring of bridge. Previous studies were mainly based primarily on measurements. However, it is difficult to optimize the SAW device only by the measurements. In this study, we report that the response signals of the impedance-loaded SAW sensor were analyzed by the combination of finite element method and circuit simulator.
