Far-end crosstalk suppression using complementary split-ring resonators in printed circuit boards

Abstract

Far-end crosstalk problem in printed circuit boards is caused due to the mutual coupling between the adjacent traces of multiconductor transmission lines. This paper treats the far end crosstalk between two parallel conductors. To mitigate the crosstalk coupled complementary spilt-ring resonators (CSRRs) are introduced in the ground plane. Comparative analysis has been carried out for three configurations with solid ground plane, by etching two CSRRs and three CSRRs in the ground plane. The experimental simulation is carried out between the frequency range of 6 GHz to 8 GHz.
