Abstract
The present invention relates to a coupler, which includes: a coupler body having an external ground formed on an outer surface thereof; a coupler line positioned inside the coupler body and electrically connected to a port electrode for signal connection with the outside; an internal ground arranged between the external ground and the coupler line and electrically connected to the external ground; and a port line having one end electrically connected to the port electrode and the other end electrically connected to the coupler line.
Claims11
A coupler comprising:
- a coupler body having an external ground formed on an outer surface thereof;
- a coupler line located inside the coupler body and electrically connected to a port electrode for signal connection with an outside source;
- an internal ground disposed between the external ground and the coupler line and electrically connected to the external ground;
- and
- a port line having one end electrically connected to the port electrode and the other end electrically connected to the coupler line,
- wherein the external ground comprises:
- a first external ground configuring a lower surface of the coupler body;
- and
- a second external ground configuring an upper surface of the coupler body,
- wherein the internal ground further includes:
- a first internal ground disposed between the first external ground and the second external ground;
- and
- a second internal ground disposed between the first external ground and the second external ground and disposed to be spaced apart at a first interval from the first internal ground,
- wherein an interval between the first internal ground and the first external ground is narrower than an interval between the second internal ground and the second external ground.
