Abstract
A variable capacitor includes first and second movable capacitor plate assemblies disposed in the interior of an enclosure and include a first and second movable capacitor plates. A first fixed capacitor plate and a second fixed capacitor plate are respectively disposed proximal to the first and second movable capacitor plates. The capacitor plates may comprise variably interdigitated concentric cylindrical blades. The first movable capacitor plate and the first fixed capacitor plate may be coaxial with the second movable capacitor plate and the second fixed capacitor plate. Actuators may be provided for independently advancing and retracting the first and second movable capacitor plate assemblies with respect to the first and second fixed capacitor plate assemblies to vary the capacitance of the variable capacitor by independently adjusting an amount of interdigitization of the capacitor plates of respective capacitor plate assembly pairs.
