ABSTRACT:
A multilayer dielectric line circuit in which a dielectric line circuit has a multilayer structure so as to be easily formed with a small overall size. In one form of the invention, first and second dielectric strips and first and second dielectric resonators are provided between respective adjacent pairs of conductor plates. The first dielectric strip and the first dielectric resonator, the first and second dielectric resonators, and the second dielectric resonator and the second dielectric strip are each coupled electrically or magnetically so as to couple the respective dielectric strips in the different layers.
