Abstract:
A multi-protocol, multi-band array antenna system may be used in Radio Frequency Identification (RFID) system reader and sensory networks. The antenna array may include array elements with an integrated low noise amplifier. The system may employ digital beam forming techniques for transmission and steering of a beam to a specific sensor tag or group of tags in a cell. The receive beam forming network is optimized for detecting signals from each sensor tag. Narrow and wideband interferences may be excised by an interference nulling algorithm. Space division multiplexing may be used by the antenna system to enhance system processing capacity.

Claim (Index 13):
A method for deriving information from an RFID tag, comprising:\n modifying RFID tag interrogation signals to be transmitted by each of a set of antenna elements of a plurality of antenna elements to maximize the power of the output at a given spatial location of the RFID tag; transmitting RFID tag interrogation signals from the plurality of antenna elements to the RFID tag by adjusting relative phases of the RFID tag interrogation signals; receiving at least one backscattered sequence of RFID tag information from the RFID tag by at least one antenna element; and deriving information from the backscattered signal.
