Abstract
Various embodiments of RFID switch devices are disclosed herein. Such RFID switch devices advantageously enable manual activation/deactivation of the RF module. The RFID switch device may include a RF module with an integrated circuit adapted to ohmically connect to a substantially coplanar conductive trace pattern, as well as booster antenna for extending the operational range of the RFID device. The operational range of the RFID switch device may be extended when a region of the booster antenna overlaps a region of the conductive trace pattern on the RF module via inductive or capacitive coupling. In some embodiments, all or a portion of the booster antenna may at least partially shield the RF module when the RFID switch device is in an inactive state.

An RFID device comprising:
- a first booster antenna adapted to extend an operational range of the RFID device;
- a second booster antenna adapted to extend the operational range of the RFID device;
- a first RF module comprising a first integrated circuit and a first set of one or more conductive traces, wherein at least one conductive trace of the first set of one or more conductive traces is configured to electrically couple to a coupling region of the first booster antenna when the coupling region of the first booster antenna is located in a first position relative to the first set of one or more conductive traces;
- a second RF module comprising a second integrated circuit and a second set of one or more conductive traces, wherein at least one conductive trace of the second set of one or more conductive traces is configured to electrically couple to the a coupling region of the second booster antenna when the coupling region of the second booster antenna is located in a second position relative to the second set of one or more conductive traces;
- and
- a switching mechanism adapted to selectively activate and deactivate the first RF module and the second RF module by changing a position of the coupling region of the first booster antenna relative to the first position relative to said first set of one or more conductive traces and by changing a position of the coupling region of the second booster antenna relative to the second position relative to said second set of one or more conductive traces.
An RFID transponder, comprising:
- a first substrate comprising a first conductive trace pattern and a second conductive trace pattern, wherein at least a first portion of the first substrate is configured to serve as a first antenna for the RFID transponder and at least a second portion of the first substrate is configured to serve as a second antenna for the RFID transponder;
- a second substrate comprising a first integrated circuit, a third conductive trace pattern, a second integrated circuit, and a fourth conductive trace pattern, wherein at least a portion of the third conductive trace pattern is configured to electrically couple with at least a portion of the first conductive trace pattern when the first substrate is located in a first position relative to the second substrate, and at least a portion of the fourth conductive trace pattern is configured to electrically couple with at least a portion of the second conductive trace pattern when the first substrate is located in a second position relative to the second substrate;
- and
- a switching mechanism adapted to selectively activate the first RF module by positioning the first substrate to position the coupling region of the first booster antenna relative to the first position relative to said first set of one or more conductive traces and to selectively activate the second RF module by positioning the first substrate to position the coupling region of the second booster antenna relative to the second position relative to said second set of one or more conductive traces.
