High-frequency transmission line and electronic device
A transmission line portion of a flat cable includes first regions and second regions connected alternately. In the first region, the transmission line portion is a flexible tri-plate transmission line including a dielectric element including a signal conductor, a first ground conductor including opening portions, and a second ground conductor which is a solidly filled conductor. In the second region, the transmission line portion is a hard tri-plate transmission line including a wide dielectric element including a meandering conductor, and a first ground conductor and a second ground conductor which are solidly filled conductors. A variation width of the characteristic impedance in the second region is larger than a variation width of the characteristic impedance in the first region.
