  • RFID TAG READER AND METHOD FOR READING AN RFID TAG
    Publication number: 20130300538
    Abstract: An RFID reader and method for reading an RFID tag is provided herein. The RFID reader operates in a “bistatic” mode, utilizing two RF antennas, one for transmitting an RF signal, and one for receiving an RF signal. The transmit and receive antennas do not “point” in a same direction resulting in lobe patterns that will intersect at an angle.
