Cable mantle for shield current suppression in a shielded cable

Cable arrangement comprising:

• at least one cable mantle for shield current suppression in a shielded cable;
• wherein the cable mantle comprises a through hole along a longitudinal direction of the cable mantle, wherein the through hole is configured for hosting the shielded cable;
• wherein the cable mantle comprises a plurality of resonant elements arranged along the longitudinal direction of the cable mantle;
• wherein each of the resonant elements comprises
• an inner tube-shaped conductive structure, which extends in the longitudinal direction between a first end section of the resonant element and a second end section of the resonant element, and which surrounds in a circumferential direction a longitudinal portion of the through hole;
• an outer tube-shaped conductive structure, which extends in the longitudinal direction between the first end section of the resonant element and the second end section of the resonant element, and which surrounds in the circumferential direction a longitudinal portion of the inner tube-shaped conductive structure, wherein the outer tube-shaped conductive structure comprises a circumferential gap so that a first longitudinal portion of the outer tube-shaped conductive structure is separated from a second longitudinal portion of the outer tube-shaped conductive structure;
• a first transversal conductive structure, which connects the inner tube-shaped conductive structure and the first longitudinal portion of the outer tube-shaped conductive structure at the first end section of the resonant element;
• a second transversal conductive structure, which connects the inner tube-shaped conductive structure and the second longitudinal portion of the outer tube-shaped conductive structure at the second end section of the resonant element;
• and
• at least one capacitor bridging the gap between the first longitudinal portion of the outer tube-shaped conductive structure and the second longitudinal portion of the outer tube-shaped conductive structure, so that an electrical behavior of the inner tube-shaped conductive structure, the first longitudinal portion of the outer tube-shaped conductive structure, the second longitudinal portion of the outer tube-shaped conductive structure, the first transversal conductive structure, the second transversal conductive structure and the at least one capacitor is equivalent to a parallel resonant circuit defining a resonance frequency of the respective resonant element;
• and
• a shielded cable comprising at least one conductive center wire and a conductive shield shielding the at least one conductive center wire, wherein the at least one conductive center wire is isolated from the conductive shield, wherein the shielded cable is hosted in the through hole of the at least one cable mantle.
