Abstract
An inductor device includes an inductor element, a substrate and a ground plane is disclosed. The ground plane includes several sub ground planes. The inductor element is set above the substrate, and the substrate is set above the ground plane. When at least one of several connection relationships between the several sub ground planes change, an inductance value of the inductor element changes.
