Patent abstract
A wireless communication system includes: a main antenna for radiating an electromagnetic wave to wireless IC chips; a reflecting plate for reflecting the electromagnetic wave from the main antenna to the wireless IC chips; and a control unit which supports the wireless IC chips. The control unit causes a difference between the receiving electromagnetic wave levels of a direct wave from the main antenna and a reflected wave from the reflecting plate received by the antenna of the wireless IC chip.
