1. An antenna system for determining a transit of a movable object through a detection area within a detection plane, the antenna system comprising:

  • at least one exciter antenna configured to provide an exciting electromagnetic field, wherein the exciting electromagnetic field or at least one spatial component thereof has a field strength above a field strength threshold in the detection area, wherein the exciting electromagnetic field is capable of exciting the movable object to emit an electromagnetic response signal comprising information on a position of the movable object; and

    at least one magnetic core of a sensor antenna for receiving the electromagnetic response signal, wherein the at least one magnetic core is positioned in a region of the exciting electromagnetic field where the field strength of the exciting electromagnetic field or at least one spatial component thereof is below the field strength threshold.
