Abstract
A tunable capacitor. The tunable capacitor has a first fixed capacitor electrode and a second fixed capacitor electrode opposite to one another. The tunable capacitor also has a movable element formed of a conductive material. The movable element is moveable between the first fixed capacitor electrode and the second fixed capacitor electrode to adjust the capacitance between the first fixed capacitor electrode and the second fixed capacitor electrode.
