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.
