Abstract:
An RFID tag device with an RFID antenna assembly that increases transmission range of the RFID tag device when adhesively coupled to a mobile device. The RFID tag device includes a RF interface that operates at a first RF frequency, a controller coupled to the RF interfaces, and the RFID antenna assembly. The RFID antenna assembly includes a first and a second dipole elements, each shaped as a half rectangle with an additional segment joining the respective element to a tuning element. The RFID antenna also includes a tuning element, which is a loop antenna, connecting the RF interface to the controller and a ferrite dielectric on the back of one of the dipole elements. A structure of the RF antennal assembly, when the RFID tag device is coupled to a mobile device, causes the mobile device to function as a reflector to increase gain of the RFID antenna assembly thereby improving transmission range.

Claim (Index 7):
A RFID tag device, comprising:\n a RF interface that operates at a first RF frequency; a controller coupled to the RF interface; an RFID antenna assembly comprising:\n a first and a second dipole elements disposed on a first side of a circuit board; \n a ferrite dielectric disposed on a second side of the circuit board, opposite the first side, wherein the ferrite dielectric is located in correspondence with one of the dipole elements; and \n a tuning element, which is a loop antenna connecting each of the first and the second dipole elements to each other; and \n a NFC antenna assembly for capturing RF energy emitted from a mobile device to which the RFID tag device is proximate, wherein the RF energy captured by the NFC antenna assembly powers circuitry of the RFID tag device to power signal transmissions from the RFID antenna assembly; wherein a structure of the RFID tag device establishes a distance between the RFID antenna assembly and the internal components of the mobile device that function as a ground plane such that, when the RFID tag device is coupled to the mobile device, the mobile device functions as a reflector to increase gain of the RFID antenna assembly thereby improving transmission range of the RFID tag device relative to a range of the RIFD tag device when not coupled to the mobile device, wherein the transmission range of the RIFID tag device when not coupled to the mobile device, wherein the transmission range of the RFID tag device as improved by the mobile device functioning as the reflector is at least twenty feet.
