    Abstract: This disclosure provides systems, methods and apparatus for providing an in-plane electromechanical systems (EMS) varactor. In one aspect, the in-plane EMS varactor may include in-plane relative translation between a second portion and a first portion. Such translation may cause a change in a gap or overlap between first electrodes that remain fixed with respect to the first portion and second electrodes that remain fixed with respect to the second portion that may cause a change in capacitance between the first and second electrodes. In some implementations, the configuration of the second portion and the first portion may be either of two mechanically bi-stable states.
