The invention relates to a wirelessly chargeable RFID electronic tag, comprising a signal receiving antenna, a signal processing module, an energy receiving antenna, a rectifying circuit module and an energy storage capacitor, wherein the rectifying circuit module comprises a low pass filter, a matching circuit, a rectifier diode and a direct-pass filter, wherein one end of the low pass filter is directly connected with the energy receiving antenna and the other end is connected with the matching circuit; the matching circuit is connected with the direct-pass filter via the rectifier diode, the other end of the direct-pass filter is directly connected with the energy storage capacitor, the other end of the energy storage capacitor is directly connected with the signal processing module, and the signal processing module is connected with the signal receiving antenna. The RFID electronic tag capable of being charged in a wireless mode has the following benefits that the advantages of an active RFID such as long recognition distance, large transmission data amount, low emission power and high compatibility and the like are reserved, and the problem that the service life of the existing active RFID electronic tag depends on the service life of cells is eliminated. The wirelessly chargeable RFID electronic tag has wide application prospect.
