ANTENNA SYSTEM AND METHOD FOR DETERMINING A TRANSIT OF A MOVING OBJECT THROUGH AN AREA OF INTEREST

摘要

An antenna system (2a-d) for determining a transit of a moving object (11) through an area of interest within a detection plane (22), the moving object (11) emitting an electromagnetic field (12), comprises at least one loop antenna (4c) for receiving the electromagnetic field (12), the at least one loop antenna (4c) comprising one or more antenna loops arranged only within an antenna plane, the antenna plane being perpendicular to the detection plane (22). The at least one loop antenna (4c) further comprises a signal terminal (60) for providing a receive signal (44a, 44b), the receive signal (44a, 44b) comprising information on a position of the moving object (11).
