Abstract (en)
[origin: EP0299125A1] A low-pass propagation structure having an inverted coaxial construction comprises a central metal conductor (1) connected to earth, one or more spiral metal conductors (3', 3'') which are insulated and wrapped around the earth conductor and acting as signal and/or power transport conductors. Advantageously, it also comprises, between the central metal conductor and the spiral metal conductors, a layer (5) of a magnetically absorbing material. <IMAGE>
