Abstract

Radiating cable (100; 100a; 100b; 100c; 100d; 100e) for radiating electromagnetic energy, comprising an inner conductor (110), an outer conductor (120) arranged radially outside of said inner conductor (110), and an isolation layer (130) arranged radially between said inner conductor (110) and said outer conductor (120), wherein said outer conductor (120) comprises one or more first openings (1202), and wherein said inner conductor (110) comprises a hollow waveguide (1100).

Claims

A radiating cable for radiating electromagnetic energy, comprising an inner conductor, an outer conductor arranged radially outside of said inner conductor, and an isolation layer arranged radially between said inner conductor and said outer conductor, wherein said outer conductor comprises one or more first openings, wherein said inner conductor comprises a hollow waveguide, and wherein said inner conductor comprises one or more second openings.

2. The cable according to claim 1, wherein said cable is configured to transmit first electromagnetic signals within a VHF frequency range between about 30 MHz to about 3 GHz.

3. The cable according to claim 1, wherein said waveguide comprises a radially outer surface with a basically elliptical cross-section.

4. The cable according to claim 1, wherein said waveguide comprises a radially inner surface with a basically elliptical cross-section.

5. The cable according to claim 1, wherein at least one of the following components comprises at least one length section with corrugations:

the inner conductor, the outer conductor, the isolation layer, the hollow waveguide.

6. The cable according to claim 1, wherein at least one of said first openings comprises a basically rectangular geometry.

8. The cable according to claim 1, wherein at least one of said second openings comprises a basically rectangular geometry.

9. The cable according to claim 1, wherein at least one of said second openings is configured with respect to a specific one of said first openings, such that electromagnetic energy is radiated through both said second opening and said specific first opening.

10. The cable according to claim 1, wherein at least one of said second openings is configured at a longitudinal coordinate of said cable such that it at least partly overlaps with at least one of said first openings.

11. The cable according to claim 1, wherein different first openings or different second openings are configured at different angular positions.

13. The cable according to claim 1, wherein said cable is configured to transmit first electromagnetic signals within a UHF frequency range between about 30 MHz to about 3 GHz.

14. The cable according to claim 1, wherein said cable is configured to transmit second electromagnetic signals within a SHF frequency range between about 3 GHz to about 3 THz.
