To provide an RF communication system of a one-to-one correspondence method between RF chips each having a single antenna and readers to realize RF communication of the readers in structures each comprising the RF chip and the antenna by means of one-to-one correspondence through remote antennas of multiple of readers or multiple sets of readers / writers, the system comprising a plurality of the readers or readers / writers connected to a plurality of the remote antennas and to provide the structures each comprising the RF chip and the antenna.

The RF communication system is provided with: a containing section wherein the structures each comprising the RF chip and the single loop second antenna and including many RF chips and many antennas are arranged at least in a line so that the second antennas are adjacent to each other at a prescribed interval; many first antennas each respectively arranged to each second antenna so as to attain RF communication with each of the single second antennas when the structures comprising the RF chips and the antennas are arranged in the containing section; a paramagnetic material for minimizing communication interference between the first and second antennas, a signal level regulation circuit; a noise filter for eliminating noise from a power supply section; and a switching means for separately driving the first and second antennas.
