Electromagnetic emission analysis of a multiband EMI filter based on sub-wavelength resonators

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.Peer ReviewedPostprint (author's final draft

Multiband EMI filter based on metamaterials

A novel compact multiband microstrip EMI filter based on metamaterials is presented. The filter is implemented by means of split-rings resonators and complementary spiral sub-wavelength resonators, conveniently coupled to the victim transmission line. The suitable combination of these resonators allows us to design several stop-band frequency responses located at 900MHz (RFID UHF), 1.8GHz (GSM) and 2.4GHz (ISM) with a significant rejection level. A 3-stages/5-stages rejection band filter has been designed and fabricated in a PCB. The experimental results show a significant rejection level in agreement with the electromagnetic simulations
