Abstract:
1. A microstrip transmission line structure with vertical stubs for reducing far-end crosstalk including: a first microstrip transmission line; a second microstrip transmission line which is distance from and parallel to the first microstrip transmission line; and a number of stubs formed at the first and second microstrip transmission lines to increase a mutual capacitance, wherein first, second, fifth, and sixth stubs formed at the first microstrip transmission line are disposed to be perpendicular to a length direction of the first microstrip transmission line, and third, fourth, seventh, and eighth stubs formed at the second microstrip transmission line are disposed to be perpendicular to a length direction of the second microstrip transmission line, wherein the second stubs formed at the first microstrip transmission line and the third stubs formed at the second microstrip transmission line are alternately disposed so as not to face each other at the same positions in the length direction of the first or second microstrip transmission line, wherein the fourth stubs are disposed at the second microstrip transmission line to extend in such a direction to be far from the first microstrip transmission line and disposed at the same positions as the second stubs disposed at the first microstrip transmission line along the length direction of the transmission line, and wherein the first stubs are disposed at the first microstrip transmission line to extend in such a direction to be far from the second microstrip transmission line and disposed at the same positions as the third stubs disposed at the second microstrip transmission line along the length direction of the transmission line.
