Abstract:
A filter element (100) includes a flat dielectric substrate (1), a ground electrode (13) on a back main surface of the dielectric substrate, resonant lines each having a shorting end in the vicinity of a boarder between a side of the dielectric substrate (1) and the ground electrode (13) and extending from the side to a front main surface of the dielectric substrate (1). The resonant lines and the ground electrode (13) constitute strip-line resonators. In any of the strip-line resonators, the line width of the resonant-line side portion is different from the line width of the resonant-line main-surface portion.
