ABSTRACT:
A frequency-variable high frequency filter comprises: a substrate; a ground conductor having an opening provided on one principal surface of the substrate; a center conductor provided in the opening to make up a coplanar line resonator with the substrate and the ground conductor; an input line and an output line provided on the other principal surface of the substrate and electromagnetically coupled with the center conductor; and a variable reactance element. The center conductor is divided into two conductor section at the position of the null point of the voltage displacement of a standing wave created in the coplanar line resonator so that the two conductor sections are separated in the longitudinal direction of the center conductor. The variable reactance element is inserted in the center conductor to connect the two conductor sections of the center conductor.
