<p>An RFID(Radio Frequency IDentification) bridge antenna is provided to increase a communication distance between a tag and a reader by coupling at least two RF antenna elements using long conductors. An RFID bridge antenna is configured to be arranged between a tag(12) and a reader(14). The tag includes a tag antenna(24). The reader includes a reader antenna(30). At least two RF antenna elements are coupled with each other by a conductor. The first RF antenna element is arranged to be close to the tag antenna, while the second RF antenna element is arranged to be close to the reader antenna. An electromagnetic carrier signal, which is transmitted by the reader antenna, is contained in the first RF antenna element. The electromagnetic carrier signal is retransmitted to the tag antenna by the second RF antenna element.</p> |
