Abstract
An inductive switch comprises an inductor that has a primary metallic winding having a boundary configured in shape of a figure eight, such as in two loops, and a plurality of secondary metallic windings arranged within the boundary of the primary metallic winding. The inductive switch includes a plurality of switches, each switch arranged in series with a respective one of the plurality of secondary metallic windings. An equal number of the secondary windings is arranged within each loop. A tunable inductor comprises at least one main metallic loop and at least one secondary metallic loop, wherein the at least one secondary metallic loop comprises a switch that is arranged to configure the at least one secondary metallic loop into at least one shorted metallic loop or at least one closed metallic loop. The at least one shorted loop is floating.
