Abstract: A system for increasing the read range of a radio frequency identification (RFID) tag, comprising: a RFID antenna (960) configured to transmit a radio frequency (RF) signal to the RFID tag; and at least one frequency selective surface (930) configured to increase a power flux density of the RF signal enroute to the RFID tag such that an effective distance between the RFID antenna and RFID tag is reduced.
