The simulation results obtained by this model are validated with an analytical method. Three cross sectional shapes are tested.

An eight-channel high-frequency transmission line structure is proposed and optimized through electromagnetic simulation. We proposed four structure that might improve the signal integrity, that is covering ground, siding metallization, grounding hole and all above at the same time. The simulation result shows that only covering ground and doing three methods at the same time can improve the signal integrity. The original model is processed with covering ground, the -3 dB bandwidth exceed 50 GHz, and the crosstalk between adjacent lines below -25 dB.
