Patent number: 5786736Abstract: A non-reciprocal circuit element which can be miniaturized while still providing a matching capacitance having a large value. A circulator, for example, has central electrodes and a multilayer substrate for forming a matching capacitance. The multilayer substrate is formed by stacking a plurality of dielectric sheets provided with central electrodes or matching capacitive electrodes with each other and integrally firing the same.
