FREQUENCY SELECTIVE SURFACE AIDS TO THE OPERATION OF RFID PRODUCTS |
摘要 |
The present invention is directed to systems that use frequency selective surfaces (FSS) to aid in the operation of radio frequency identification (RFID) devices and products. In one embodiment, a system for interrogating radio frequency identification (RFID) tags includes a conveyor belt and a RFID reader. The conveyor belt has a first surface and a second surface. The first surface is configured to receive an item in which an RFID tag is affixed and the second surface is configured to slide on a metal slide plate. The RFID reader is configured to transmit instructions embodied in a radio frequency (RF) signal to the RFID tag, wherein the metal slide plate is positioned between the RFID reader and the RFID tag and comprises a frequency selective surface that is substantially transparent to the RF signal. |
