A study of feeding options aimed at cancelling crosstalk in multiconductor transmission lines

This paper presents practical verification of a concept of total elimination of crosstalk between signals propagating in multiconductor transmission lines. The assumption is that the crosstalk should be eliminated by proper feeding and matching at the line ends, in the presence of physical coupling between conductors all along the lines. A family of proper feeding and matching configurations is investigated. Results of measurements are presented for two of them. Another one is verified by modelling.
