Abstract:

 The double coil sensor based on mutual inductance coupling principle was developed in order to detect performance parameters of electronic article surveillance (EAS) radio frequency (RF) tag. The physical model and dynamic mathematical model of detection sensor were constructed according to the results of analysis for the model of EAS RF tag. Then the frequency response characteristic of the sensor was analyzed. The double coil with parallel structure was proposed in order to make the electromagnetic field evenly distributed around the tag detection region, and to facillitate the continuous online detection of the tag. Effect of the number of turns in the coil and spatial structure parameters on sensitivity was tested based on circuit parameters simulation analysis, and all parameters of the sensor were determined. The detecting results indicate that the sensor has high detection precision, stable property and fast response, which can meet the online detection requirements of EAS RF tag performance parameters.
