DIFFERENTIAL SIGNAL TRANSMISSION LINE

摘要

A differential signal transmission line may include first, second, and third conductors and first and second insulative materials. The first and second conductors may be configured to carry positive and negative signals of a differential signal. The first insulative material may be positioned between the first conductor and the second conductor and may have an effect on a differential mode dielectric constant of the differential signal that is greater than an effect on a common mode dielectric constant of the differential signal. The second insulative material may be positioned to electrically isolate the third conductor from the first conductor, the second conductor, and the first insulative material and may have an effect on the differential mode dielectric constant of the differential signal that is lower than an effect on the common mode dielectric constant of the differential signal.
