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.

Abstract: PURPOSE: A laminated transformer for high frequency is provided to ensure high impedance variation rate even in using inductor with a low capacity by using a capacitor. CONSTITUTION: A transformer is comprised of a first inductor(L1), a first capacitor(C1), a second inductor(L2) and a second capacitor(C). The first inductor(L1) has a ceramic sheet(300) which is provided with a ground terminal pattern(301) and a coil pattern(302). The first capacitor(C) has two ceramic sheets(330,340) which are provided with capacitor patterns(331,341), respectively. The second inductor(L2) has a ceramic sheet(350) which is provided with a first input terminal pattern(351) and a coil pattern(352). The second capacitor(C2) has two ceramic sheets(380,390) which are provided with capacitor patterns(381,391). Each sheet has via-holes filled with paste so that the coil patterns and capacity patterns are electrically connected via the conductive paste.
