US 12,542,342 B2 · Directional coupler

Abstract

A directional coupler includes a conductor serving as a primary line disposed in a multilayer body and conductors serving as a plurality of secondary lines that are disposed in the multilayer body and each of which is capable of being electromagnetically coupled to the conductor serving as the primary line. A facing area where the conductor serving as the secondary line and the conductor serving as the secondary line face each other is smaller than a facing area where the conductor serving as the secondary line and the conductor serving as the primary line face each other. A distance between the conductor serving as the secondary line and the conductor serving as the secondary line is longer than a distance between the conductor serving as the secondary line and the conductor serving as the primary line.

Dependent claims

A directional coupler comprising:

a multilayer body comprising a plurality of insulator layers that are stacked;
a primary line in the multilayer body;
and
a first secondary line and a second secondary line, which are in the multilayer body and each of which is electromagnetically coupled to the primary line,
wherein
the first secondary line and the second secondary line are at different positions in a stacking direction of the plurality of insulator layers, and
a first facing area, where the first secondary line and the second secondary line face each other, is smaller than a second facing area where the first secondary line and the primary line face each other and a third facing area where the second secondary line and the primary line face each other.
