Kind Code:
A1
Abstract:
Disclosed is a power saving-type wireless communication system which is formed from a small and simple structure, can be produced at low cost, and uses a wireless IC device with a fast information transmission speed. A wireless communication system is provided with a reader/writer and a wireless IC device (1A) for processing a specified wireless signal. The wireless IC device (1A) is provided with a wireless IC element (50) and a radiating element (a loop electrode (30)), and is fixed to a frame (61). The directional characteristics of the wireless IC device (1A) are altered due to a metallic gate (60) coming into contact with the wireless IC device (1A), and then communication with the reader/writer becomes possible.
