Abstract
A directional coupler includes a main line, a sub line, and a first parasitic element. The main line includes a first main line portion. The sub line includes a first sub line portion electromagnetically coupled with the first main line portion. The first parasitic element receives a first magnetic flux which is generated by the first main line portion when a current flows through the first main line portion and generates a second magnetic flux passing through the first sub line portion due to electromagnetic induction.
