Multiband EMI filter based on metamaterials
نویسندگان
چکیده
A novel compact multiband microstrip EMI filter based on metamaterials is presented. The filter is implemented by means of splitrings 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/5stages 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.

متن کاملElectromagnetic interference reduction in printed circuit boards by using metamaterials: a conduction and radiation impact analysis
This work aims to compare the implementation of two metamaterials for reducing electromagnetic interference (EMI) in printed circuit boards (PCBs). Specifically, complementary split-ring resonators (CSRRs) and electromagnetic bandgaps (EBGs) were etched on the ground plane of a microstrip transmission line. Both techniques were compared as EMI filters, taking into account frequency response, si...

متن کاملAn EMI Filter Selection Method Based on Spectrum of Digital Periodic Signal
This paper describes a new method for the selection of an appropriate signal line Electromagnetic Interference (EMI) filter. To date, EMI filter selection has been based on the measurement of the radiation of the entire device. The new selection method based on the signal’s Fast Fourier Transform (FFT) measurement has proved to be efficient. The EMI filter is optimized separately for each line....
