Radiated Emissions Of Interconnect Cables

Short ribbon cables are often used to connect components inside a computer or other electronic device. Crosstalk between the closely spaced wires of a multiconductor ribbon cable is often a problem. Interspersing ground wires and signal-carrying wires is a common and effective method for reduction of crosstalk on these types of cables [ll. In this study, the radiated emissions of a ribbon cable are analyzed. The goal is to determine how different signal wire/ground wire configurations affect the radiated fields of a ribbon cable. A five wire model of a 10 cm ribbon cable is used. Lumped circuit analysis and the method of moments are used to predict the currents and radiated fields.
