  • METHOD AND APPARATUS FOR RFID READER/ANTENNA
    Publication number: 20080129512
    Abstract: A radio frequency identification (RFID) system include a reader and a tag. The RFID reader includes at least one reader antenna, the reader antenna is configured as a lossy loop antenna with a beam coverage area. The RFID tag includes a loop antenna, the tag loop antenna cooperates with the reader antenna to receive and transmit radio frequency signals between the reader antenna and the tag antenna when the tag is located with a near field distance from the reader antenna.
