Abstract
A triplate stripline on a multilayer circuit board includes an inner conductor sandwiched between two ground patterns having a finite pattern width that is 10 times the pattern width of said inner conductor or less. The two ground patterns are short-circuited on opposite transverse ends thereof by a plurality of vias disposed in a longitudinal direction which is a signal transmitting direction of the stripline. An adjacent stripline is of the same structure as the triplate stripline. Each of the striplines has a cross-sectional shape in which one inner conductor is surrounded by the two ground patterns and the vias on the opposite sides. The inner conductor is thus prevented from suffering ambient electromagnetic noise and electromagnetic interference such as crosstalk or the like.
