ABSTRACT:
A coupled line element has a plurality of coupled lines equalized to each other in line length to set a phase difference between output signals within a desired range. The coupled lines are wound to form a spiral section. An extension is formed continuously with an end of one or more of the coupled lines forming an inner winding in the spiral section. The line length of this coupled line is thereby equalized to that of the coupled line forming an outermost winding in the spiral section. Alternatively, the coupled lines can be formed into two spiral sections which are wound in opposite directions.
