Abstract
A DC block with a band-notch characteristic using a defected ground structure (DGS), includes a pair of coupled lines for being formed parallel to each other on one surface of a dielectric and blocking a flow of a DC, and at least one DGS for being formed on an area of the rear surface of the dielectric corresponding to each coupled line and comprising an etched region formed by etching a part of a ground surface bonded to the dielectric and a metal region formed in the etched region. Accordingly, the stop band of the desired bandwidth in the desired communications band can be formed and the size of the communications system can be reduced.
