Patent ID: 8561911

Claim:
An RFID device comprising: a booster antenna adapted to extend the operational range of the RFID device; a first RF module comprising a first integrated circuit and a first conductive trace pattern, wherein at least a portion of the first conductive trace pattern is adapted to electrically couple to a coupling region of the booster antenna when the coupling region of the booster antenna is located in a first position relative to the first conductive trace pattern; a second RF module comprising a second integrated circuit and a second conductive trace pattern, wherein at least a portion of the second conductive trace pattern is adapted to electrically couple to the coupling region of the booster antenna when the coupling region of the booster antenna is located in a second position relative to the second conductive trace pattern; and a switching mechanism adapted to change the position of the coupling region of the booster antenna relative to the positions of said first and second RF modules.
