RFID TAG READER AND ANTENNA UNIT FOR RFID TAG |
| 摘要 |
<p>A control unit 100 generates a control signal for selecting an antenna unit 200, and transmits the control signal to the antenna unit 200. Based on the antenna selecting control signal, each antenna unit 200 performs control so as to achieve impedance matching of a matching circuit 212 when the own antenna unit 200 is selected, and so as not to achieve impedance matching of the matching circuit 212 when the own antenna unit 200 is not selected.</p> |
