    摘要： Disclosed is a resonator having a three dimensional Defected Ground Structure (DGS) in the transmission line which shows high quality factor. In order to achieve this object, the resonator having a three-dimensional DGS in the transmission line according to the first example of the present invention comprises a substrate installed at the center of the resonator floating in the air through supporting members installed on both ends of the substrate; a transmission line for transmitting signals installed on the upper surface of the substrate; an upper ground plane member installed on the upper surface of the substrate with predetermined interval from the surface of the substrate, wherein a DGS pattern with a predetermined shape is formed on each portion of the body of the ground plane member symmetrically with respect to the transmission line to form a resonator; a lower ground plane member installed on the lower surface of the substrate with predetermined interval from the surface of the substrate, wherein a DGS pattern with a predetermined shape is formed on each portion of the body of the ground plane member symmetrically with respect to the transmission line to form a resonator; an upper cover installed closely contacting the upper surface of the upper ground plane member to seal the upper opening of the DGS pattern formed on the upper ground plane member and to protect the upper ground plane member at the same time; and a lower cover installed closely contacting the lower surface of the lower ground plane member to seal the lower opening of the DGS pattern formed on the lower ground plane member and to protect the lower ground plane member at the same time.
