1. An RFID device comprising:
a multilayer reactive strap having
a first substrate;
a first conductor portion enclosing a first area and being disposed on a first side of first substrate;
a second conductor portion enclosing a second area and being disposed on a second side of the first substrate, and
a first connection coupling the first conductor portion and the second conductor portion together, thereby forming a multiturn coil that includes both the first conductor portion and the second conductor portion, wherein the multiturn coil of the connected first conductor portion and second conductor portion provides more inductance within a given area than a conductor having a single turn enclosing the same area.
