摘要：
An RF tag system is provided, in which in addition to a method of easily sending back MPSK modulated sub-carrier signals on the RF tag side, communication protocols and circuit systems for accurately demodulating modulated waves on the RF tag reader side can be implemented, data transmission from an RF tag to an RF tag reader can be realized over a long operating distance at high speed, and an RF tag can be operated for a long lifetime.
