Radio communication system
First Claim
1. A radio communication system, comprising:
- a radio IC chip used for identification;
a transmitting/receiving device for performing transmission and reception of information between the radio IC chip by a radio wave; and
a radio-wave directive unit provided in a space where a plurality of the radio IC chips are accumulated, wherein the radio-wave directive unit directs traveling direction of the radio wave irradiated from the transmitting/receiving device towards the radio IC chips.

Abstract
It is to provide a radio communication system capable of performing highly reliable reading/writing communication even though the RFID tags face in the random directions. The radio communication system comprises an RFID tag used for identification, a reader/writer for performing transmission and reception of information between the RFID tag by radio waves, and a plurality of reflecting plates in a space where a plurality of RFID tags are accumulated. The reflecting plates direct traveling direction of the radio wave irradiated from the reader/writer towards the RFID tags. A part of the radio waves irradiated from an antenna of the reader/writer is directed to travel three-dimensionally towards the space by the effect of the reflecting plates. Moreover, the radio waves traveling in the same direction among the reflected radio waves by the plurality of reflecting plates together allow attenuation caused due to distance to be reduced extremely.
