Abstract:
1. A mobile device comprising: an energy storage device configured to receive energy from a low frequency (LF) radio frequency (RF) signal; a high frequency (HF) RF transceiver coupled to a processing module, wherein the energy storage device is coupled to provide power to the storage module and to the HF-RF transceiver; and a multifunction antenna coupled to the HF-RF transceiver and coupled to the energy storage device, wherein one end of the multifunction antenna is grounded and the energy storage device is coupled to an opposite end of the multifunction antenna, and wherein the multifunction antenna is divided into a first segment and a second segment by a first impedance circuit and the HF-RF transceiver is coupled to the multifunction antenna adjacent to the first impedance circuit.
