Abstract
A balun transformer and inductor are proposed having geometries that provide several windings of conductors in small areas. In one embodiment, the windings of the balun transformer and inductor have octagonal shapes with a lower and upper layer of wound conductors. The upper layer lies on supporting posts that stand on pedestals. The lower layer of conductors shadow the upper layer while curving to avoid the pedestals.
