Patent attributes
An RFID apparatus includes at least two antennas that are positioned to increase the maximum effective range of the RFID device. The RFID apparatus includes an RFID device, and the RFID device includes an antenna connected to a circuit having a transmitter. The second antenna is positioned relative to the RFID device to increase the MER of the RFID apparatus relative to conventional RFID devices while remaining separated (i.e. no direct physical contact) from the RFID device. In at least one embodiment, the second antenna is separated from the RFID device and positioned relative to the RFID device to induce a coupling of a signal to the RFID device. In at least one embodiment, the second antenna is positioned to overlay at least a portion of the circuit of the RFID device. In at least one embodiment, the RFID device is a passive-type RFID device.
