Reading RFID tag using antenna within enclosure |
| 摘要 |
A method of reading an RFID tag using an RFID reader includes providing an RF-blocking enclosure having a port. The RFID reader has an antenna located within the enclosure. The enclosure is positioned so that the port is adjacent to a conductive surface and the RFID tag is within the enclosure. The RFID reader is activated at a selected read power level to read the tag in the enclosure. |

1. A method of reading an RFID tag using an RFID reader, comprising:
providing an RF-blocking enclosure having a port, wherein an antenna of the RFID reader is located within the enclosure; positioning the enclosure so that the port is adjacent to a conductive surface and the RFID tag is within the enclosure; activating the RFID reader at a selected read power level to read the tag in the enclosure; and wherein the RFID reader transmits on a selected wavelength, the enclosure is configured so that the port and the antenna are separated by a distance substantially equal to a multiple of one-quarter of the selected wavelength, and the positioning step includes positioning the RFID tag in the port. |
