Voltage tunable laminated dielectric materials for microwave applications

摘要: A tunable dielectric structure includes a first layer of material, second material positioned adjacent to the with having constant that is less than and electrodes for applying controllable voltage across thereby controlling wherein at least one between layers material. The materials can be formed in various shapes assembled orientations respect each other. used devices including coaxial cables, cavity antennas, microstrip lines, coplanar waveguides.
