Abstract
Abstract A microstrip transmission line comprises a plurality of signal-carrying lines disposed along a dielectric ribbon and separated by a predetermined spacing. Ground-plane conductors are disposed on the opposite side of the ribbon in staggered relation to the signal-carrying lines such that the ground-plane conductors occupy spaces corresponding to the gaps between adjacent signal-carrying lines. This arrangement lowers the capacitance and raises the impedance of the transmission line while maintaining high signal line density.
