1. A dielectric substrate having a multiturn inductor comprising:
- a) a multilayer dielectric body comprising a plurality of layers;
b) a multiturn inductor buried within the dielectric body, each turn of the inductor comprising a bottom portion, a top portion and two side portions, the bottom portion and top portion being parallel and in different layers of the dielectric body, the side portions being parallel to each other and extending between the top and bottom portions and comprising vias in the dielectric body, wherein the top and bottom portions have a lower crossectional area than the side portions and wherein the top and bottom portions each comprise two parallel wiring lines in juxtaposition.
