Abstract (en)
[origin: CA2683799A1] The invention relates to an improved RFID-antenna-system for a goods iden tification system (WIS), said RFID antenna system being characterised by the following characteristics: the at least two patch antennas (21) form a grou p of patch antennas (A, B) for grouping and for reducing the size of the mon itoring area in the direction of the passage (3') and the at least two patch antennas (21) are arranged at the same distance in relation to the surface of the base (5) of the path of the passage (3) and/or on the same horizontal plane or are offset in relation thereto, such that a straight line passes t hrough the centre and/or centre of gravity of at least two adjacent patch an tennas (21) formed with the horizontal plane and/or a plane that is parallel to the surface of the base (5) at an angle .alpha. that is
