Abstract
An embodiment of the present disclosure provides an impedance matching circuit including a matching network. The matching network includes a first port and a second port, and one or more variable reactance components. The one or more variable reactance components are operable to receive one or more variable voltage signals to cause the one or more variable reactance components to change an impedance of the matching network. At least one of the one or more variable reactance components includes a first conductor coupled to one of the first port or the second port of the matching network, a second conductor, and a tunable material positioned between the first conductor and the second conductor. Additionally, at least one of the first conductor and the second conductor are adapted to receive the one or more variable voltage signals to cause the change in the impedance of the matching network. Additional embodiments are disclosed.
