A tunable patch antenna is described herein that includes a ground plane on which there is located a substrate and on which there is located a patch. The patch is split into two parts (e.g., rectangular parts) which are connected to one another by one or more voltage-tunable series capacitors. Each part has a radiating edge which is connected to one or more voltage-tunable edge capacitors. Also described herein, is a method for electronically tuning the tunable patch antenna to any frequency within a band of operation which is in a range of about 30% of the center frequency of operation.

Conformal frequency-agile tunable patch antenna

A voltage-controlled tunable filter includes at least two cavity resonators electrically coupled to each other. A voltage tunable dielectric capacitor is positioned within each of the resonators. Connections are provided for applying a control voltage to the voltage tunable dielectric capacitors. An input is coupled to the one of the resonators, and an output is coupled to the other resonator.

Electronically tunable combline filters tuned by tunable dielectric capacitors

This invention provides a phased array antenna comprising an input, a feed network electronically coupled to the input, a plurality of radiating elements, a plurality of continuously voltage tunable phase shifters for receiving signals from the feed network and providing phase shifts for the signals prior to transmitting the signals to the radiating elements, and a controller for controlling the phase shift provided by the phase shifters. The phased array antennas can be configured to produce beams that can be scanned in one dimension (one-dimensional) or two dimensions (two-dimensional) by using continuously adjustable phase shifters that are based on low cost, low loss voltage-tunable dielectric materials.
