Abstract:
An embedded capacitor including a dielectric layer disposed between opposing faces of electrodes, in which the dielectric layer includes a high-loss dielectric layer and one or more insulating layers in contact with the high-loss dielectric layer. The dielectric layer may have a two-layer structure or a three-layer structure in which an insulating layer is additionally interposed between the high-loss dielectric layer and the electrode, thereby decreasing the dielectric loss while maintaining a high dielectric constant, compared to capacitors including a single-layer dielectric structure.

Thus, there are no restrictions in the aspects of installation and maintenance, and accurate lane recognition is possible without an influence on the weather conditions around the road.
