Abstract:
1. An RFID antenna system for a goods identification system (GIS) comprising: at least one RFID antenna device read out from RFID tags equipped with a microchip, the at least one RFID antenna device being arranged at least on one side of a passageway or passage region for monitoring, and on two opposing sides with respect to a passageway or passage region extending therebetween, laterally offset from each other and therefore transversely to a passage direction, the RFID antenna device and/or a side limit receiving the RFID antenna device comprising at least two antennas the at least two antennas for the goods identification system (GIS) comprising patch antennas, the at least two patch antennas being arranged mutually offset in the direction of the passageway or passage region, or at least with one component mutually offset in the passage direction, and the at least two patch antennas being arranged at an equal spacing from a floor space of the passageway and/or on the same horizontal plane or offset thereto, in such a way that a straight line laid through the center points and/or centers of gravity of at least two adjacent patch antennas encloses an angle α with respect to a horizontal plane and/or a plane that is parallel to the floor space, which angle is ≦45°.
