Abstract
A semi-rigid cable for the transmission of microwaves, such as those used for radar or for digital television. This cable has a symmetrical strip line with a dielectric having an almost rectangular section, with a width close to the thickness of the dielectric and external conductive strips with a width that is substantially greater than that of the central conductor. This symmetrical strip line is advantageously surrounded by an absorbent sheath. The entire unit is protected by an ordinary metallic shielding and by a standard external mechanical protective sheath.
