| 发明名称 | Universal RFID tags and methods | ||
| 摘要 | Radio frequency identification (RFID) devices, and methods of manufacture are described herein. In one implementation, an RFID device comprises a near field only RFID tag that does not function as a far field RFID tag and is pre-manufactured; and a conductive element independent from the near field only RFID tag and configured to function as a far field antenna, wherein the conductive element extends a length and includes a central region and includes at least one distal region defining a voltage end of the conductive element. The near field only RFID tag and a distal region of the conductive element are coupled in proximity to each other such that the RFID device functions in both a near field and a far field. | ||
