Beschreibung
Zusammenfassung:	A 24 GHz band-pass filter includes a step impedance resonator, a first U-shape feeding portion, a second U-shape feeding portion, short-circuit stubs and open-circuit stubs. The step impedance resonator includes a first main portion, a second main portion, and a connection portion for connecting the main portions to each other. The first main portion and the second main portion are electrically connected to a first signal input/output port and a second signal input/output port. The first U-shape feeding portion is electrically connected between the first main portion and the first signal input/output port. The second U-shape feeding portion is electrically connected between the second main portion and the second signal input/output port. The short-circuit stubs are electrically connected to coupling segments of the step impedance resonator. The open-circuit stubs are electrically connected to the first U-shape feeding portion and the second U-shape feeding portion.
