BATTERY-ASSISTED BACKSCATTER RFID TRANSPONDER

摘要

A kind of radio frequency transponder (28) includes at least one battery (60), it, which is coupled to, provides electric power to operate transponder and at least one antenna (52), is configured to receive and backscattering RF interrogation radiations are from inquiry equipment (32). Integrated circuit (56) is arranged to the code that storage includes information, and only and the energy that is provided by battery of power, to change the radiation characteristic of antenna in response to code to modulate the information to the backscattered radiation.
