Dual-carrier-powered RFID tag circuit and data transceiving method

A data transceiving method of a dual-carrier-powered Radio Frequency Identification (RFID) tag circuit, comprising an RFID chip and an antenna, wherein the RFID chip comprises a signal receiving connection terminal, a signal transmitting connection terminal, and a power supply connection terminal;

• the antenna comprises a first antenna module and a second antenna module;
• the first antenna module and the second antenna module are independent of each other;
• the power supply connection terminal of the RFID chip is connected to the first antenna module;
• the signal transmitting connection terminal and the signal receiving connection terminal of the RFID chip are connected to the second antenna module, and the data transceiving method of the dual-carrier-powered RFID tag circuit comprises:
• providing power supply, comprising obtaining, by the first antenna module, energy from radio electromagnetic waves, and supplying power to the RFID chip;
• signal receiving, comprising receiving, by the second antenna module, a wireless radio frequency signal, and transmitting the wireless radio frequency signal to the RFID chip;
• and
• signal transmitting, comprising emitting, by the RFID chip, a signal through the second antenna module.
