INDUCTIVE MODULE AND DEVICE

An inductive module with a miniaturized metamaterial structure includes an insulating substrate, two coil units, and a magnetic unit. The insulating substrate has opposing first and second surfaces and a through hole extending between the first and second surfaces. The coil units are respectively disposed on the first surface and the second surface of the insulating substrate, and are electrically connected to each other through the through hole. Each of the coil units includes a closed loop coil. The magnetic unit corresponds in position to a portion of the coil unit, surrounds said portion of the coil unit, and has an opening.
