Measurement of the stochastic electromagnetic field coupling to an unshielded twisted pair cable with a matched termination

The coupling of stochastic electromagnetic fields into an unshielded twisted double-wire transmission line has been measured in a reverberation chamber. One end of the line features a matched load resistance and is therefore anechoic. With this chosen configuration, the influence of the pitch distance onto the frequency-dependent coupling can be clearly exposed. The measurement results confirm an existing simulation model that is based on transmission line theory and the plane wave integral representation.
