Abstract
A multi-layer, multi-turn structure for an inductor having a plurality of conductor layers separated by layers of insulator is described. The inductor further comprises a connector electrically connected between the conductor layers. The structure of the inductor may comprise a cavity therewithin. The structure of the inductor constructed such that electrical resistance is reduced therewithin, thus increasing the efficiency of the inductor. The inductor is particularly useful at operating within the radio frequency range and greater.
Claims36
An inductor comprising:
- a) a first conductor layer;
- b) a second conductor layer spaced apart from the first conductor layer, the first conductor layer and the second conductor layer being electrically conductive;
- c) an insulator layer positioned in the space between the first conductor layer and the second conductor layer thereby forming a structure, wherein an inductor cavity having an inductor cavity width, an inductor cavity length, and an inductor cavity depth resides therewithin;
- d) at least one connector electrically connecting the first conductor layer and the second conductor layer;
- and
- e) wherein when an electrical current is propagated within at least the first conductor layer, a magnetic flux is generated within the inductor;
- and
- f) wherein when a change in at least one of a frequency, a magnitude, or a waveform shape of the propagated electrical current occurs an inductance is generated.
