Coupled stripline device e.g. for microwave stripline filter structure, has dielectric tuning element for adjusting coupling positioned on outside of coupling slit between coupled striplines

摘要

The stripline device has striplines (1,2,3) which are coupled via at least one coupling slit (11,21,23), with adjustment of each coupling via a dielectric tuning element (4,5,6) positioned on the outside of the coupling slit. The tuning element may be displaced perpendicular to the plane in which the striplines are positioned for altering the coupling. An Independent claim for application of a coupled stripline device for a superconductive microwave filter structure is also included.
