Abstract

A cable is provided which has a dielectric medium forming a chamber which can also be filled by the dielectric medium. The cable additionally has a first dielectric waveguide element and a second dielectric waveguide element. The first dielectric waveguide element is arranged at a distance from the second dielectric waveguide element. The first dielectric waveguide element runs along a longitudinal direction of the cable through the chamber formed by the dielectric medium, and the second dielectric waveguide element runs along the longitudinal direction of the cable through the chamber formed by the dielectric medium. The polarization direction of the first dielectric waveguide element differs from the preferred polarization direction of the second dielectric waveguide element.

First claim

The invention claimed is:

a dielectric medium forming a chamber; and
first, second, and third dielectric waveguide elements, which are each spaced at a distance from one another and each extend along a longitudinal direction of the cable through the chamber,
the preferred polarisation directions of the first, second and third dielectric waveguide element each differing from one another by an angle of 60°.

2. Cable according to claim 1 , wherein the dielectric medium has a round cross-section.

3. Cable according to claim 1 , the preferred polarisation direction of the first dielectric waveguide element being determined by a respective cross section of the first dielectric waveguide element and the preferred polarisation direction of the second dielectric waveguide element being determined by a respective cross section of the second dielectric waveguide element.

4. Cable according to claim 1 , wherein respective dielectric constants of the first and second dielectric waveguide elements are at least substantially identical.

5. Cable according to claim 1 , the dielectric constant of the dielectric medium being lower than at least one of the dielectric constants of the first and second dielectric waveguide elements.

6. Cable according to claim 1 , further having a jacket, which surrounds the chamber.

7. Cable according to claim 6 , the jacket being at least partly conductive and/or non-conductive.

8. Cable according to claim 6 , the jacket ending flush with the dielectric medium.

9. Cable according to claim 1 , wherein the dielectric medium is formed in separate segments that each surrounds a respective one of the first, second, and third dielectric waveguide elements.

10. Method for manufacturing a cable, the method comprising the steps:
provision of first, second, third and fourth dielectric waveguide elements, which are each spaced at a distance from one another and the waveguide elements being twisted respectively by comparison with one another, a preferred polarisation direction of the first dielectric waveguide element differing from a preferred polarisation direction of the second dielectric waveguide element in the cable, and
the preferred polarisation direction of the first dielectric waveguide element corresponding to a preferred polarisation direction of the third dielectric waveguide element, and

embedding of the first, second, third, and fourth dielectric waveguide elements into a chamber made of a dielectric medium, or
embedding of the first, second, third, and fourth dielectric waveguide elements into respective segments of the dielectric medium, which forms the chamber by stranding of the segments.

11. Method according to claim 10 , wherein the first, second, third, and fourth dielectric waveguide elements are embedded into respective segments of the dielectric medium, said segments then being twisted relative to one another along the length of the cable.

12. Method according to claim 10 , wherein the segments of the dielectric medium are rectangular in cross section.

13. Method according to claim 10 , wherein the segments of the dielectric medium are segmented in cross section.

14. Cable having:

provision of first, second and third dielectric waveguide elements, which are each spaced at a distance from one another and the waveguide elements being twisted respectively by comparison with one another, so that a preferred polarisation direction of the respective waveguide elements differs by 60° in each case; and
embedding of the first, second and third dielectric waveguide elements into a chamber made of a dielectric medium, or elements
embedding of the first, second and third dielectric waveguide elements into respective segments of the dielectric medium, which forms the chamber by stranding of the segments.

18. Method according to claim 17 , wherein the first, second, and third dielectric waveguide elements are embedded into respective segments of the dielectric medium, said segments then being twisted relative to one another along the length of the cable.
