An improved bi-mesa structure optimized for resonator mounting is proposed. To evaluate mounting influences, the frequency differences between clamp and free X-edge conditions are calculated using a two-dimensional finite element method in the X-Y' region. When the outer mesa height was lower than 20% of the thick area, the frequency differences are less than 10% of standard-type bi-mesa resonator values. These results indicate that the improved bi-mesa structure has good separation from the mounting influences.
