ABSTRACT:
A miniature, electrostatically actuated, stub tuner which is operable to dynamically tune a transmission line in response to control signals. With the use of integrated circuit processing the transmission line is fabricated on a substrate and at least one stub tuner is fabricated over the substrate and is movable relative to the transmission line in response to electrostatic fields produced when the control signals are selectively applied to rows of control electrodes.
