Abstract
In this paper, we study the effect of shielding on the crosstalk between three-conductor transmission lines. The main idea of this work is to demonstrate that shielded lines can be more compact with best performance in terms of crosstalk than unshielded conductors. We demonstrate that by using shielded conductor we can reduce crosstalk with minimum spacing between conductors. We present H-T hybrid electric equivalent model for three-conductor transmission lines. This model allows us to evaluate near-end crosstalk performance between conductors. Crosstalk obtained by shielded lines separated by distance d is as low as these obtained without shield separated by 20d.
