摘要： Filter circuitry is provided with a series element and a parallel element. The filter circuitry transmits signals that fall within a certain passband and attenuates signals that don't fall within the certain passband. The series element is comprised of a resonance element having antiresonance characteristics, and the parallel element is comprised of a series circuit including an inductor and a capacitor.

摘要： On each surface of a dielectric substrate, arranged are a first conductor line pattern having a plurality of first line segments and a second conductor line pattern having a plurality of second line segments. Ends of each first conductor line segment overlap the second conductor line segments, and the first and second line segments are connected via through-holes, thereby forming a single spiral conductor line. Each second conductor line segment for connecting adjacent first conductor line segments has a pair of end parts connected to the first conductor line segments via through-holes and a halfway part having a smaller width.
