摘要: Method and system of determining a locational characteristic RFID tag. At least some the illustrative embodiments are systems comprising radio frequency identification (RFID) reader, phased-array reading antenna coupled to reader (the plurality elements). The is configured determine value indicative direction tag relative based on an analysis phase signals induced each elements by return signal from
