摘要:
A filter includes a resonant unit which has a plurality of resonators respectively formed of each microstrip line and connected in cascade with one another, and a coupling unit which has at least one inter-resonator coupling of the resonant unit in an area within a range of ±45° (⅛-wavelength) in an electrical length from a voltage maximum point at a intermediate of the microstrip line.
