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 11):
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; \n wherein the RFID tag device is a multilayered structure with a circuit board comprising one layer, said circuit board comprising the RF interface, the controller, the RF antenna assembly, wherein the circuit board is joined to an upper layer and to a lower layer of the multilayered structure via a low surface energy, press adhesive layer, wherein one of the layers of the multilayered structure is a foam layer, wherein the lower layer of the multilayered structure is an adhesive layer for coupling the RFID tag device to an exterior case of the mobile device, wherein the foam layer establishes a distance between the circuit board and the internal components of the mobile device that function as a ground plane to ensure the mobile device functions as the reflector to increase gain of the RFID antenna assembly as opposed to the ground plane attenuating a RF signal from the RFID antenna assembly, wherein the transmission range of the RFID tag device as improved by the mobile device functioning as the reflector is at least twenty feet.
