A Novel Metamaterial Structure to Reduce Far-End Crosstalk in Printed Circuit Boards

Far-End crosstalk is a common problem in a printed circuit boards when two transmission lines are in close proximity. This paper proposes a newly designed method to reduce the far-end crosstalk using metamaterials as a complementary split ring resonator (CSRRs). The CSRRs are etched in the ground plane and are used to control the radiated electromagnetic fileds. Comparative analyses are taken for three cases with solid ground plane etching one CSRR and 2 CSRRs in the ground plane. Analysis shows that a significant reduction in the crosstalk is achieved when 2 CSRRs are etched in the ground plane. This design is made to reduce the crosstalk without additional components.
