摘要： An RFID system (200) includes an RFID reader (202), an antenna array (204) and a length compensation unit (215). The RFID reader (202) is configured to interrogate RFID antennas. The antenna array (204) includes two or more RFID antennas (206) connectable to the RFID reader (202) via a series of cable links (208). Each RFID antenna (206) is associated with a respective cable link (208), and each cable link (208) has a cable length. The length compensation unit (215) is associated with each RFID antenna (206), and is configured to adjust a total cable length between the RFID reader (202) and a respective RFID antenna (206) to be an effective cable length.
