Directional coupler

摘要

A directional coupler includes a first conductive track, a second conductive track, and a conductive structure. The conductive structure includes a first partial region that is arranged nearer to the first conductive track than the first conductive track is to the second conductive track. The conductive structure also includes a second partial region that is arranged nearer to the second conductive track than the first conductive track is to the second conductive track.

1. A directional coupler comprising:
a substrate; a first conductive track provided on the substrate, wherein the first conductive track comprises a first port for forward transmitted waves and a second port for reflected transmitted waves; a second conductive track provided on the substrate, wherein the second conductive track comprises a third port for input and a fourth port for output; a conductive structure provided on the substrate and configured as a coupling loop or coupling frame operable to couple the first conductive track with the second conductive track, the conductive structure comprising:
a first partial region that is arranged nearer to the first conductive track than the first conductive track is to the second conductive track;a second partial region that is arranged nearer to the second conductive track than the first conductive track is to the second conductive track; andwherein the conductive structure is arranged on a different plane of the substrate than the first conductive track and the second conductive track.
