Reduced crosstalk microstrip transmission-line

摘要

A reduced crosstalk microstrip transmission-line has a plurality of microstrips sandwiched between a lower base dielectric layer of flexible circuit material and an upper coverlay with higher permittivity and of different flexible circuit material than the base dielectric layer. With the higher permittivity of the coverlay, the thickness of the coverlay is selected such that the microstrip transmission-line retains practical flexibility and far-end crosstalk to a first neighboring microstrip from a driving channel is zero.
