PROBLEM TO BE SOLVED: To provide a dual-band coupler unit, capable of simultaneously coupling signals of two different frequency bands and markedly reducing the area.;SOLUTION: The dual-band coupler unit includes a first coupled line, a second coupled line, a short transmission line, a first transmission line, and a second transmission line. The first coupled line and the second coupled line are substantially in parallel with each other, and are substantially the same length. One end of the short transmission line is connected to one end of the first coupled line, and the other end of the short transmission line is connected to one end of the second coupled line. One end of the first transmission line is connected to the other end of the first coupled line, and one end of the second transmission line is connected to the other end of the second coupled line.;COPYRIGHT: (C)2011,JPO&INPIT
