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 1):
A radio frequency identification (RFID) tag device, comprising:\n a radio frequency (RF) interface that operates at a first RF frequency; a controller coupled to the RF interface; and an RFID antenna assembly comprising:\n a first and a second dipole elements a first side of a circuit board, wherein the first and second dipole elements are shaped as a half rectangle with an additional segment joining the respective element to a tuning element; \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 the tuning element, which is a loop antenna, wherein the first and second dipole elements are printed on a surface of a printed circuit board, \n wherein a structure of the RFID tag device establishes a distance between the RFID antenna assembly and the internal components of a mobile device that functions 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, whereby improving transmission range of the RFID tag device relative to a range of the RFID tag device when not coupled to the mobile device, wherein the transmission range of the RFID tag device is improved by the mobile device functioning as the reflector is at least twenty feet.
