An embodiment of the present disclosure provides a circuit including an antenna having a tunable component. The tunable component can be operable to receive a variable signal to cause the tunable component to change a reactance of the antenna. The tunable component can include a first conductor coupled to the antenna, a second conductor, and a tunable material positioned between the first conductor and the second conductor, where at least one of the first conductor or the second conductor, or both are adapted to receive the variable signal to cause the change in the reactance of the antenna. Additional embodiments are disclosed.

Tunable microwave devices with auto-adjusting matching circuit

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.

An embodiment of the present invention provides an apparatus, comprising an input port and a dynamic impedance matching network capable of determining a mismatch at the input port and dynamically changing the RF match by using at least one matching element that includes at least one voltage tunable dielectric capacitor. The matching network may be a 'Pi', a 'T', or &#x201c;ladder&#x201d; type network and the apparatus may further comprise at least one directional coupler capable of signal collection by sampling a portion of an incident signal, a reflected signal or both. In an embodiment of the present invention, the apparatus may also include a control and power control & logic unit (PC LU) to convert input analog signals into digital signals and sensing VSWR phase and magnitude and processing the digital signals using an algorithm to give it a voltage value and wherein the voltage values may be compared to values coming from the coupler and once compared and matched, the values may be passed to a Hi Voltage Application Specific Integrated Circuit (HV ASIC) to transfer and distribute compensatory voltages to the matching network elements. Additional embodiments are disclosed.
