Abstract: A coupler is provided to reduce reflection loss without increase of insertion loss by controlling a size and a shape of an inner ground layer formed between coupled lines. A coupler includes a coupler main body, two micro strip transmitting lines, and a ground layer. The coupler main body is made of ceramic dielectric. A ground electrode and a port electrode pattern are formed on a top surface and a bottom surface of the coupler main body. Two micro strip transmitting lines are formed inside the coupler main body. Two micro strip transmitting lines are broadside-coupled in order to form coupled lines(601,603) and port lines(701,703,705,707). The ground layer is positioned between two micro strip lines. The ground layer is connected to the ground electrode of the top surface and the bottom surface of the coupler main body.
