ABSTRACT:
A twisted-pair conductor line structure is formed on a substrate (22) having insulated conductive layers (31, 32). The conductive layers are used to form first, second, third, and fourth conductive planar segments (40, 41, 42, 43). A first conductive link (44) joins the first and second planar conductive segments to provide a first signal path. Similarly, a second conductive link (46) joins the third and fourth planar conductive segments to provide a second signal path. The first and second conductive links are operatively arranged to form a twist (17) in the first and second signal paths, such that the resulting magnetic fields (57, 59) around the twisted conductive segments will be opposite to each other for cancelling each other out, in order to reduce the magnetic field radiation to the surrounding environment.
