Patent abstract
A coherent RFID tag design having no internal power source is disclosed. The design exhibits a longer detection range and less interference relative to conventional tag designs. The coherent RFID tag design operates in a locked or stabilized fashion, in that the frequency at which energy is parasitically coupled to the RFID tag (via its antenna) is the same as the frequency at which the RFID tag transmits information utilizing the same antenna. The RFID tag design allows a greater number of RFID tags to be deployed, without causing cross-tag interference issues and the like.
