Abstract
A method of utilizing beamforming to selectively locate one or more ambient electromagnetic power harvesting (AEPH) chips, implemented by a reader apparatus comprising multiple antennas, the method comprises transmitting, to the AEPH chips, an interrogation signal from multiple transmit antennas by a reader application executing on a processor of the reader apparatus in a first frequency band to activate the AEPH chips; receiving, from at least one AEPH chip by multiple receive antennas of the reader apparatus, one or more signals in response to the interrogation signal; processing the one or more signals to determine a direction of the at least one AEPH chip; and adjusting, using a beamformer, a beam direction of the multiple transmit antennas of the reader apparatus in the direction of the at least one AEPH chip to deliver the maximum power to the at least one AEPH chip.
