Abstract
Apparatus for reading an RFID tag includes an RF-blocking enclosure having a port and adapted to receive through the port a non-RFID-active object having an RFID tag affixed thereto. An RFID reader has a reader antenna located outside the enclosure. The antenna transmits an RF downlink signal in a particular direction. An RF grating is arranged between the reader antenna and the port so that, after the enclosure receives the object having the tag, the port is located in the transmit direction from the reader antenna, and RF energy transmitted from the reader antenna has a selected linear polarization after passing through the grating.
