摘要： A multi-mode RFID tag includes a power generating and signal detection module, a baseband processing module, a transmit section, a configurable coupling circuit, and an antenna section. In near field mode, the configurable coupling circuit is operable to couple the transmit section to a coil or inductor in the configurable coupling circuit to transmit an outbound transmit signal using electromagnetic or inductive coupling to an RFID reader. In far field mode, the configurable coupling circuit is operable to couple the transmit section to the antenna section, and the multi-mode RFID tag then utilizes a back-scattering RF technology to transmit the outbound transmit signal to RFID readers.
