Abstract:
An RFID communication system comprising a near field coupler that is capable of selectively communicating with a targeted transponder positioned among a group of multiple adjacent transponders. The coupler is configured to receive communication signals from a transceiver and transmit the signals to a targeted transponder in a transponder operating region. The coupler includes a number of radiating elements spaced apart and a switching element. The switching element selectively couples one or more of the radiating elements to the transceiver. The coupled elements transmit the signals into the transponder operating region by emanating a near field effect. The pattern of the near field effect may be adjusted by changing the combination of the coupled radiating elements.
