An RFID antenna, an RFID tag, and an RFID system are provided to improve the reliability of a product by generating isotropic radiation pattern with the RFID antenna and removing a shadow area of the RFID tag(RFID). An RFID antenna(140) comprises a closed loop-type conductive body(120) and an opened loop-type conductive body(130). The closed loop-type conductive body is used to supply electricity. The opened loop-type conductive body is separated at one side of the closed loop-type conductive body and formed along the closed loop-type conductive body. The closed and opened loop-type conductive bodies are formed rectangularly or ovally. The closed and opened loop-type conductive bodies are bent at least once and formed with a same shape on a same plain surface. The RFID tag(100) includes an IC(Integrated Circuit) chip(110) contacted with the conductive body. The RFID system includes a reader communicated with an RFID. |
