Abstract: PURPOSE: A band pass filter using a DGS is provided to increase the number of stages and a bandwidth by forming a defected ground structure having a constant pattern at a ground surface of a band pass filter. CONSTITUTION: One stage band pass filter includes micro scrip lines(1,3) of an input/output terminal, a micro scrip line(2), a dielectric substrate(4), and a ground surface(5). The micro scrip line(2) is arranged between the micro scrip lines(1,3). Lower ground surfaces of the micro scrip lines(1,3) are etched to form a defected ground structure(6). The defected ground structure(6) has an LC resonance circuit feature. The defected ground structure(6) is used for a small component such as a multi-layer or a monolithic microwave integrated circuit. A defected ground structure pattern is used in an input/output terminal of an active element.
