Abstract

A coaxial cable is disclosed that may include an inner conductor and an outer conductor surrounding the inner conductor in a coaxial relationship. The coaxial cable may also include an insulative material located between the inner conductor and the outer conductor. A thickness of the insulative material between the inner conductor and the outer conductor may be increased in every direction at a bent portion of the coaxial cable as compared to the thickness of the insulative material between the inner conductor and the outer conductor at a non-bent portion of the coaxial cable.

First claim

What is claimed is:

1. A coaxial cable, comprising:
an inner conductor that includes a first inner conductor surface and a second inner conductor surface, the second inner conductor surface is substantially perpendicular to the first inner conductor surface and the first inner conductor surface is located in two different planes as a result of a bent portion of the coaxial cable, wherein a thickness of the inner conductor at the bent portion of the coaxial cable varies;
an outer conductor surrounding the inner conductor in a coaxial relationship, the outer conductor including a first outer conductor surface that corresponds to the first inner conductor surface and a second outer conductor surface that corresponds to the second inner conductor surface; and
an insulative material located between the inner conductor and the outer conductor, a thickness of the insulative material between the second inner conductor surface and the second outer conductor surface is greater at the bent portion of the coaxial cable than a non-bent portion of the coaxial cable and the thickness of the insulative material at the bent portion of the coaxial cable varies.

2. The coaxial cable of claim 1 , wherein a thickness of the inner conductor at the bent portion of the coaxial cable is less than a thickness of the inner conductor at the non-bent portion.

3. The coaxial cable of claim 1 , wherein the bent portion of the coaxial cable includes a corner at an approximately 90 degree angle.

4. The coaxial cable of claim 3 , wherein the inner conductor has a thickness at the bent portion of the coaxial cable that is less than a thickness of the inner conductor at the non-bent portion and is positioned such that the thickness of the insulative material between the inner conductor and the outer conductor throughout the entire bent portion of the coaxial cable is larger than the thickness of the insulative material between the inner conductor and the outer conductor in the non-bent portion of the coaxial cable.

5. The coaxial cable of claim 4 , wherein the insulative material and the outer conductor form an approximately 90 degree angle at the bent portion of the coaxial cable and the inner conductor forms an angle plus or minus 10 degrees from 90 degrees at the bent portion of the coaxial cable.

6. The coaxial cable of claim 1 , wherein a cross-section of the coaxial cable is circular, square, quadrilateral, or elliptical.

7. A coaxial cable, comprising:
an inner conductor;
an outer conductor surrounding the inner conductor in a coaxial relationship; and
an insulative material located between the inner conductor and the outer conductor, a thickness of the insulative material between the inner conductor and the outer conductor is increased in every direction at a bent portion of the coaxial cable as compared to the thickness of the insulative material between the inner conductor and the outer conductor at a non-bent portion of the coaxial cable, the thickness of the insulative material at the bent portion of the coaxial cable varies, and a thickness of the inner conductor at the bent portion of the coaxial cable varies.

8. The coaxial cable of claim 7 , wherein a thickness of the inner conductor at the bent portion of the coaxial cable is less than a thickness of the inner conductor at the non-bent portion.

9. The coaxial cable of claim 7 , wherein the insulative material and the outer conductor form an approximately 90 degree angle at the bent portion of the coaxial cable and the inner conductor forms an angle plus or minus 10 degrees from 90 degrees at the bent portion of the coaxial cable.

10. The coaxial cable of claim 7 , wherein a cross-section of the coaxial cable is round, square, quadrilateral, or elliptical.

11. A coaxial cable, comprising:
an inner conductor that includes:
a first inner conductor surface; and
a second inner conductor surface, the second inner conductor surface is substantially perpendicular to the first inner conductor surface and the first inner conductor surface is located in two different planes as a result of a bent portion of the coaxial cable,
wherein a first thickness of at least a first portion of the inner conductor in the bent portion of the coaxial cable is less than a second thickness of at least a second portion of the inner conductor in a non-bent portion of the coaxial cable and the first thickness of at least the first portion of the inner conductor in the bent portion of the coaxial cable varies;

an outer conductor surrounding the inner conductor in a coaxial relationship, the outer conductor including:
a first outer conductor surface that corresponds to the first inner conductor surface and is located in a first plane and a second plane;
a second outer conductor surface that corresponds to the second inner conductor surface; and
a corner defined by the bent portion of the coaxial cable,
wherein the bent portion of the coaxial cable being between the first plane and the second plane and including the corner; and

an insulative material located between the inner conductor and the outer conductor, a thickness of the insulative material between the second inner conductor surface and the second outer conductor surface is greater at the bent portion of the coaxial cable than the non-bent portion of the coaxial cable and the thickness of the insulative material at the bent portion of the coaxial cable varies.

12. The coaxial cable of claim 11 , wherein the corner defined by the bent portion of the coaxial cable is an approximately 90 degree angle.

13. The coaxial cable of claim 11 , wherein the corner defined by the bent portion of the coaxial cable is an approximately 135 degree angle.

14. The coaxial cable of claim 11 , wherein the corner defined by the bent portion of the coaxial cable is defined by more than one vertex.

15. The coaxial cable of claim 11 , wherein a cross-section of the coaxial cable is circular, square, quadrilateral, or elliptical.
