초록

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 an 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 divis...

청구항

The invention claimed is: 1. A method for deriving information from an RFID tag, comprising:transmitting RFID tag interrogation signals to an RFID tag;digitizing the signals received by each antenna element of an array of antenna elements from the RFID tag in response to the interrogation signals;performing signal processing on the digitized signals to determine relative phase and weight differences between the signals received by each of the antenna elements in the array of antenna elements from the RFID tag in response to the interrogation signals;dela...
