Abstract

A defected microstrip structure (DMS) method is used for crosstalk reduction between parallel coupled pair transmission lines (CPTLs). To reduce the couplings from the adjacent transmission line, a new DMS is designed and etched on one of the transmission line. Additionally, equivalent circuit model is also studied to provide an effective analysis method for analyzing the crosstalk of DMS-CPTLs by considering the S-parameters, namely, S11, S12, S13 and S14. The proposed designs are verified by using HFSS based on FEM and the equivalent circuit is studied by using ADS. The results show that the far-end crosstalk and near-end crosstalk are reduced by about 30dB and the equivalent circuit simulation agrees well with the HFSS simulation.
