Abstract
In some embodiments, an RFID device may include a multilayer reactive strap having a first substrate, a first conductor portion, a second conductor portion, and a first connection. The first conductor portion may enclose a first area and may be disposed on a first side of first substrate. A second conductor portion may enclose a second area and may be disposed on a second side of the first substrate. A first connection may couple the first conductor portion and the second conductor portion together, and may thereby form a multiturn coil that includes both the first conductor portion and the second conductor portion.
Claims34
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.
A method of forming an RFID device comprising:
- forming a multilayer reactive strap by
- disposing a first conductor portion enclosing a first area on a first side of the first substrate,
- disposing a second conductor portion enclosing a second area on a second side of the first substrate,
- using 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 first conductor portion is connected to the second conductor portion by using a coupling capacitance.
