The inner layer FR - 4 (DK = 4.2) and the high - frequency layer are designed with a hybrid dielectric transition to optimize inter - layer impedance continuity and reduce signal reflection.
ANSYS HFSS is used to perform full - wave simulation on microstrip lines/striplines to accurately calculate the line width, spacing, and dielectric thickness:
For 50Ω microstrip lines: The line width is 0.68mm (Rogers 4350B layer)
For 100Ω differential pairs: The line width is 0.15mm/spacing is 0.2mm
