タ。In a microstrip circuit in which a ground conductor is arranged on the lower surface of a dielectric substrate and a line is arranged on the upper surface, first and second open-ended lines are arranged in parallel in the same direction perpendicular to the input and output lines in the vicinity of the input and output lines. Further, a third open-ended line is placed on an extension of the first line with a gap, a fourth open-ended line is placed on an extension of the second line with a gap, and a third open-ended line is placed on an extension of the second line with a gap. The first, third, second, and fourth strip lines are connected by conductors different from the conductors of the strip lines, respectively,
