| Summary: | Five process parameters of the embedded substrate, the width of transmission line, the thickness of transmission line, coupling length of transmission lines, the distance between transmission line and substrate dielectric constant were chosed as control factors. By establishing five factors and four levels orthogonal experiment table with 16 parameter levels , cross talk between transmission lines was analyzed. The results show that the distance between transmission lines is the greatest influence on the crosstalk, then the coupling length of transmission lines, and the substrate dielectric constant, the width of transmission line and transmission line thickness have little influence on the crosstalk. The optimal parameter combination is W4T4S4L1D1 with the transmission line width of 15 mil, the transmission line thickness of 70 μm, transmission line coupling distance of 2 mm, coupling length of 5 mm, a dielectric constant of 4.3.
