BACKGROUND OF THE INVENTION

Field of Invention

The present disclosure relates to basic electronical elements. More particularly, the present disclosure relates to an inductor device.

Description of Related Art

The various inductors nowadays have advantages and disadvantages. For instance, a spiral type inductor has higher Q value and large mutual inductance if it is designed correctly. However, the mutual inductance and the coupling condition of the spiral type inductor occurs amongst its coils. When it comes to a 8-shaped inductor, the mutual inductance and the coupling condition occur at another coil of the 8-shaped inductor since magnetic orientations of two coils of an 8-shaped inductor are opposite. Furthermore, 8-shaped inductor occupies more space in a device other than another type of inductor. Therefore, the applications of the spiral type inductor and the 8-shaped inductor are limited.
