Abstract: A step impedance resonator filter including a first resonator and a second resonator is disclosed. The first resonator includes a first coupled line and a first tapped line connected to the first coupled line. The second resonator includes a second coupled line and a second tapped line connected to the second coupled line. The second coupled line is coupled with the first coupled line. The first tapped line has a first central line which is spaced from an end face of the first coupled line at a first distance. The second tapped line has a second central line which is spaced from an end face of the second coupled line at a second distance. The first distance is larger than the second distance. As such, the performance of the step impedance resonator filter can be improved.
