In order to solve radiated electromagnetic interference generated by the radio frequency identification system, the convenient approach was proposed to diagnose the radiated EMI mechanism based on near-field measurement and suppress radiated EMI noise by utilizing radio frequency EMI filters. It can avoid the complicated EMI noise analysis and suppression methods such as 3-m anechoic chamber and electromagnetic shielding. The standard results show that RFID system can pass the GB 9254 Class A and the noise decrease 24 dB~tV/m by employing the suggested approaches, and thus good realization.
