Abstract
In this paper the electromagnetic emission of sub-wavelength EMI filter based on SRR and CSRR resonator has been analysed by means of near E and H fields simulation with the FDTD SEMCAD® software. The target bands are 900 MHz (RFID UHF), 1.8 GHz (GSM) and 2.4 GHz (ISM, Instrumentation, Scientific and Medical). A 3-stages/5-stages rejection band filter was designed and fabricated in a PCB. The preliminary simulation results show that the more significant emissions take place at higher frequencies, the 1.8 GHz GSM band and ISM band (2.4 GHz), and are located at the resonators’ surface.
