Miniature monolithic ceramic coupler for electronic circuits

摘要

An inductive coupling device for external circuitry to pass electric currents therethrough via inductively coupled electrodes, comprises a monolithic, dielectric, ceramic block made from a multiplicity of stacked dielectric ceramic plates or layers all bonded together. First and second flat rectangular Z-shaped electrodes are embedded in the block between the ceramic layers and bonded thereto. The electrodes are spaced apart by one dielectric layer and generally overlap at least in part for effectively coupling to each other. The block also carries electrically conductive grounding films or layers bonded to the underside of the top and bottom dielectric layers of the block. These films are coupled to adjacent ones of the Z-shaped electrodes. The block may be rectangular in configuration. Conductive stripes on lateral and end faces of the block contact ends of the Z-shaped electrodes and ends of the grounding films and serve as terminals for connecting external circuitry thereto.
