Abstract

Coaxial cable shielding. In one example embodiment, a coaxial cable includes a center conductor, a dielectric, a tape, and a jacket. The tape defines first and second edge portions that each borders an interior portion. The thickness of the first edge portion is less than the thickness of the interior portion. The dielectric surrounds the center conductor. The tape is wrapped around the dielectric such that the first edge portion overlaps with the second edge portion. The jacket surrounds the tape.

Claims

1. A coaxial cable comprising:

a center conductor surrounded by a dielectric;

a tape defining first and second edge portions that each borders an interior portion, the thickness of the first edge portion being less than the thickness of the interior portion, the tape being wrapped around the dielectric such that the first edge portion overlaps with the second edge portion, wherein the tape comprises a conductive layer and a dielectric layer adjacent to the conductive layer, and wherein the thickness of the dielectric layer in the first edge portion is less than the thickness of the dielectric layer in the interior portion;

a bonding layer surrounding said tape; and

a jacket surrounding the bonding layer.

2. The coaxial cable as recited in claim 1, wherein the thickness of the second edge portion is less than the thickness of the interior portion.

3. The coaxial cable as recited in claim 1, wherein the conductive layer comprises a metallic layer.

4. The coaxial cable as recited in claim 1, wherein the tape further comprises a bonding agent layer adjacent to the dielectric layer.

5. The coaxial cable as recited in claim 4, wherein the tape further comprises an aluminum layer adjacent to the dielectric layer.

6. The coaxial cable as recited in claim 5, wherein the tape further comprises a polymer bonding agent layer adjacent to the aluminum layer.

7. The coaxial cable as recited in claim 6, wherein the thickness of the polymer bonding agent layer in the first edge portion is less than the thickness of the polymer bonding agent layer in the interior portion.

8. The coaxial cable as recited in claim 1, further comprising a braid that surrounds the tape and that is surrounded by the jacket.

9. The coaxial cable as recited in claim 1, wherein the tape is longitudinally wrapped around the dielectric.

10. A coaxial cable comprising:

a center conductor;

a dielectric surrounding the center conductor;

a tape surrounding the dielectric, the tape defining first and second edge portions that each borders an interior portion, the thickness of the first edge portion being less than the thickness of the interior portion, the tape being wrapped around the dielectric such that the first edge portion overlaps with the second edge portion, wherein the tape comprises a conductive layer and a dielectric layer adjacent to the conductive layer, and wherein the thickness of the dielectric layer in the first edge portion is less than the thickness of the dielectric layer in the interior portion;

a braid surrounding the tape;

a bonding layer surrounding the braid; and

a jacket surrounding the bonding layer.

11. The coaxial cable as recited in claim 10, wherein the thickness of the second edge portion is less than the thickness of the interior portion.

12. The coaxial cable as recited in claim 10, further comprising a messenger wire running parallel to the center conductor and surrounded by the jacket.

13. The coaxial cable as recited in claim 10, wherein the conductive layer comprises a metallic layer.

14. A coaxial cable comprising:

a center conductor,

a dielectric surrounding the center conductor;

a first tape surrounding the dielectric, the first tape defining first and second edge portions that each borders an interior portion, the thickness of the first edge portion being less than the thickness of the interior portion, the first tape being wrapped around the dielectric such that the first edge portion overlaps with the second edge portion, wherein the first tape comprises a conductive layer and a dielectric layer adjacent to the conductive layer, and wherein the thickness of the dielectric layer in the first edge portion is less than the thickness of the dielectric layer in the interior portion;

a braid surrounding the first tape;

a second tape surrounding the braid;

a bonding layer surrounding the second tape; and

a jacket surrounding the bonding layer.

15. The coaxial cable as recited in claim 14, wherein the thickness of the second edge portion is less than the thickness of the interior portion.

16. The coaxial cable as recited in claim 14, wherein the second tape defines first and second edge portions that each borders an interior portion, the thickness of the first edge portion being less than the thickness of the interior portion, the second tape being wrapped around the braid such that the first edge portion overlaps with the second edge portion.

17. The coaxial cable as recited in claim 14, further comprising a second braid surrounding the second tape and surrounded by the jacket.

18. The coaxial cable as recited in claim 17, further comprising a messenger wire running parallel to the center conductor and surrounded by the jacket.

19. The coaxial cable as recited in claim 14, wherein the conductive layer comprises a metallic layer.
