Crossed ring anchored disk resonator for self-alignment of the anchor

open access: yesJournal of Advanced Research, 2014
Misalignment is a problematic challenge in RF MEMS resonators. It causes asymmetry in the ultra symmetric radial contour mode disk resonators and degrades their performance by increasing the insertion loss and decreasing their quality factors (Q).
