Micromechanical resonators having stub anchors are described. The micromechanical resonators may be suspended, being connected to a substrate or support by one or more anchors. The anchor(s) may include one or more stubs which can impact the acoustic impedance of the anchor(s). The stub(s) may have various shapes and sizes. In some instances, multiple resonators may be coupled together by a connector having one or more stubs.
