摘要： A tunable phase shifter includes a waveguide, a finline substrate positioned within the waveguide, a tunable dielectric layer positioned on the finline substrate, a first conductor positioned on the tunable dielectric layer, and a second conductor positioned on the tunable dielectric layer, with the first and second conductors being separated to form a gap. By controlling a voltage applied to the tunable dielectric material, the phase of a signal passing through the waveguide can be controlled.

摘要： Tunable dielectric materials including an electronically tunable dielectric ceramic and a low loss glass additive are disclosed. The tunable dielectric may comprise a ferroelectric perskovite material such as barium strontium titanate. The glass additive may comprise boron, barium, calcium, lithium, manganese, silicon, zinc and/or aluminum-containing glasses having dielectric losses of less than 0.003 at 2 GHz. The materials may further include other additives such as non-tunable metal oxides and silicates. The low loss glass additive enables the materials to be sintered at relatively low temperatures while providing improved properties such as low microwave losses and high breakdown strengths.

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.

摘要： A multi-layered capacitor includes three or more capacitor layers. A first layer includes a first DC-biased, tunable capacitor. A second layer, acoustically coupled to the first layer, includes a second DC-biased, tunable capacitor. A third layer, acoustically coupled to the second layer, includes a third DC-biased, tunable capacitor. Each dielectric of the first, second, and third capacitors has a resonance of about the same frequency, within 5%, and inner electrodes of the first, second, and third capacitors have a resonance of about the same frequency, within 5%. The resonance of each layer is a function of at least thickness, density, and material. The first, second, and third layers are biased to generate destructive acoustic interference, and the multi-layer capacitor is operable at frequencies greater than 0.1 GHz.
