Abstract (en)
[origin: EP0150870A2] 1. A high-frequency cable including spacers arranged equidistantly on the inner conductor and a synthetic resin sheath surrounding the spacers, in which the frequency-selective energy flowback produced by systematic in-homogeneities and the resultant interference of the transmission properties are reduced in that the relative dielectric constant of the insulating material provided between the inner and the outer conductor is changed within the permissible limits of the wave resistance and the dimensions along the length of the cable with periods whose length is very long compared to the operating wavelength, characterized in that the period length of the dielectric change at the lowest interference frequency is approximately 5 dB.
