Abstract
A dielectric composition that can be fired at a temperature of below 900° C. The dielectric composition has a dielectric constant of 25–35 and a quality factor (Qxf) of 6,000–20,000 GHz. The composition comprises 3–16 wt % of KO—NaO—LiO—BO—SiOsystem glass frit and 84–97 wt % of BaO—TiOsystem dielectric ceramics. The composition can be effectively applied to construct a part of a ceramic multi-layer packaging as a resonator form such as a filter or an antenna, etc.
