Patent

CA 2153040

An electronic article security system (10) includes a transmitter (100) for generating electromagnetic energy and a single antenna (150) for emitting electromagnetic energy received from the transmitter (100) to establish an electromagnetic field within the detection zone and for sensing disturbances within the electromagnetic field, including disturbances resulting from a security tag (12) within the detection zone. A receiver (200) processes signals from the antenna (150) relating to sensed disturbances and provides output signals. A data processing and control section (300) analyzes the output signals and determines whether a sensed disturbance within the electromagnetic field is caused by the presence of a security tag (12) within the detection zone. The output signals from the receiver (200) are analyzed in accordance with predetermined criteria and pattern recognition techniques based upon receiver output signals which would be expected if a security tag (12) were present in the detection zone to establish a security tag probability percentage.
