Radio frequency identification (RFID) tag and RFID system including the same

The utility model provides an RFID tag and a radio frequency identification system including the same, belonging to the field of a radio frequency identification technology. The tag antenna of the RFID tag includes two symmetrical E type radiators, an inductance loop, a T type microstrip line and a bending feed line, wherein the E type radiators are used for realizing the capacitive match of the tag antenna and a tag chip, the inductance loop and the T type microstrip line are both used for realizing the inductive match of the tag antenna and the tag chip. The RFID tag antenna is flexibly designed, and the conjugate match of the impedance of the antenna and the tag chip impedance is flexible, thus being easy to realize the good conjugate match of the impedance of the tag antenna and the impedance of the tag chip; and the radiation characteristic is excellent, and the area is small.
