Vias (106) are typically of a lower impedance than the signal lines (102, 128) connected to them. The noise and reflected signals resulting in impedance mismatch may require circuits to be operated at a frequency far lower than desired. An embodiment avoids impedance mismatch in circuits and achieves an advance in the art by providing a via (106) with higher impedance through the addition of split ring resonators (104, 112, 120, 126) to each end of the via (106).

A coaxial transition includes a first conductor aligned along a first axis. The transition also includes a ground shield surrounding the first conductor such that a first gap exists between the first conductor and the ground shield. An electric field radiates between the first conductor and the ground shield through the first gap. The transition further includes a second conductor aligned along a second axis and coupled to the first conductor. The second conductor forms a second gap between the second conductor and a portion of the ground shield. A first portion of the electric field radiates between the second conductor and the ground shield through the second gap. The transition also includes a top ground plane aligned substantially parallel to the second conductor. A third gap exists between the top ground plane and the second conductor. The second gap and the third gap are substantially parallel with the second conductor therebetween.

Coaxial and twisted pair conductive yarn structures reduce signal crosstalk between adjacent lines in woven electrical networks. A coaxial conductive yarn structure includes an inner conductive yarn having a plurality of conductive strands twisted together. An outer conductive yarn is wrapped around the inner conductive yarn. An insulating layer separates the inner and outer yarns. A twisted pair conductive yarn structure includes first and second conductive yarns, each including a plurality of conductive strands being twisted together. The first and second conductive yarns are twisted together to forma helical structure. In a woven electrical network, at least one conductor of adjacent conductive yarn structures is connected to ground to reduce signal crosstalk. Coaxial and twisted pair yarn structures may also be formed simultaneously with weaving or knitting the threads that make up the structures into a fabric.
