Signal line structure for a radio-frequency identification system |
摘要 |
<p>The invention provides one or more signal line structures that produce an electromagnetic field having a magnitude of at least an interrogation threshold of a radio frequency identification (RFID) tag for a substantial portion of an interrogation region. The signal lines may be made from copper and laid across a shelf in a storage area. The electromagnetic field may cause the tag to backscatter radio frequency (RF) signals to an RFID reader via the signal line.</p> |
