Microstrip lines far-end crosstalk cancellation using striplines in hybrid PCB structure

This paper proposes a method that can generate striplines (SL) crosstalk with opposite polarity against microstrip lines (MS) crosstalk by designating specific dielectric constant difference between core and prepreg of striplines. And it also demonstrates how the crosstalk cancellation can be achieved by superposition of crosstalk caused by microstrip lines and the designed striplines.
