An RFID(Radio Frequency IDentification) antenna, an RFID tag, and an RFID system are provided to increase the utilization of the RFID tag by performing communication in dual frequency bands by the RFID antenna. An RFID tag(100) includes an IC chip(101) and an RFID antenna(140). The RFID tag communicates with different readers in dual frequency bands. The RFID antenna includes first and second electric conductors(105,107) and first and second conductors(120,121) having an open slot structure on both surfaces of a supporter(110). The supporter is realized in a rectangular structure so as to irradiate an RF(Radio Frequency) signal. The IC chip is electrically connected between the first and second electric conductors. The first and second electric conductors supply a current fed by the IC chip at a feeding point to the conductors. A slot(130) is formed between the first and second conductors. |
