Abstract
An RFID antenna system for providing an interrogation zone over a width of a dock bay door comprises a horizontally arranged array of antennas, each of the antennas being substantially coplanar with all of the other antenna(s), and a circuit operatively coupled to the array for providing a respective signal to each of the antennas to enable each of the antennas to emit an interrogation field. The interrogation fields emitted from the respective antennas jointly form an interrogation zone in a volume positioned above each of the antennas. Each of the antennas is mounted on, within or beneath a portion of the floor which is close to the dock bay door.
