Abstract: In order to measure the quality parameters of the electronic antitheft label used in an electronic article surveillance(EAS) system, according to its structure, the method utilizing the principle of mutual inductance to measure the quality parameters was thought out. The features of the model of monocoil sensor and doublecoil sensor were studied, and their simulation on Matlab was made out. Finally, a doublecoil sensor in lab was produced, and its test was carried out with good effect. The senor has been successfully applied in detection system of antitheft label.
Key words: electronic article surveillance(EAS); mutual inductance; noncontact; antenna
