Abstract:
1. An RFID device comprising: a booster antenna configured to extend the operational range of the RFID device; an RF module comprising an integrated circuit and a set of one or more conductive traces, wherein at least one conductive trace of said set of one or more conductive traces comprising said RF module is adapted to electrically couple to a coupling region of the booster antenna when said set of one or more conductive traces comprising said RF module is located in a first position relative to the coupling region of the booster antenna; and a switching mechanism configured to move the booster antenna to change the position of the booster antenna between the first position and a second position in which the coupling region of the booster antenna is not electrically coupled to said at least one conductive trace of said set of one or more conductive traces comprising said RF module, wherein at least a portion of the booster antenna is adapted to at least partially shield the RF module when the coupling region of the booster antenna is located in the second position relative to said set of one or more conductive traces comprising said RF module.
