Abstract

Embodiments of the present invention are directed to a cable assembly that is adapted to be connected to an antenna and a base unit. The cable assembly may be relatively flat with shielding and structures to reduce ground currents or other interference. Embodiments of the cable assembly include at least two coaxial cables for transmit and receive signals that are separated to reduce crosstalk or other interference. The cable may also include one or more inner cables, such as differential or switching pairs, between the two coaxial cables to provide cables for control, power, switching, or other functions. The inner cables may be positioned in parallel to each other and to each of the coaxial cables. In some embodiments, the inner cables include a first inner cable located at a first end of the inner cables and a second inner cable located at a second end of the inner cables. One coaxial cable may be positioned adjacent and parallel to the first inner cable, which the other coaxial cable may be positioned adjacent and parallel to the second inner cable.

Claims

1. A cable, comprising:

a first coaxial cable;

a second coaxial cable located in parallel to the first coaxial cable;

a plurality of inner cables positioned between the first coaxial cable and the second coaxial cable, each of the plurality of inner cables being positioned in parallel to each other, the first coaxial cable and the second coaxial cable;

an outer casing surrounding the first coaxial cable, the second coaxial cable and the plurality of inner cables; and

wherein the first coaxial cable, the second coaxial cable, and the plurality of inner cables are positioned essentially within the same plane, the first coaxial cable and the second coaxial cable being positioned on opposites sides of the plurality of inner cables, the first coaxial cable and the second coaxial cable being adapted to connect to an antenna and a base unit.

2. The cable of claim 1, wherein each of the first coaxial cable, second coaxial cable, and plurality of inner cables comprises a first end and a second end, the cable further comprising a shield attached to an end of at least one of:

the first coaxial cable;

the second coaxial cable; and

an inner cable.

3. The cable of claim 2, wherein the shield is a ferrite bead.

4. The cable of claim 3, wherein the ferrite bead is attached to an end of a plurality of inner cables.

5. The cable of claim 1, wherein the plurality of inner cables is a ribbon cable.

6. The cable of claim 1, further comprising an inner cable shield surrounding the plurality of inner cables.

7. The cable of claim 6, further comprising an inner casing surrounding the plurality of inner cables and the inner cable shield, wherein the outer casing surrounds the inner casing and inner cable shield.

8. A cable comprising:

a first coaxial cable;

a second coaxial cable located in parallel to the first coaxial cable;

a plurality of inner cables located in essentially the same plane as the first coaxial cable and the second coaxial cable, the plurality of inner cables comprising a first inner cable and a second inner cable, each of the plurality of inner cables being located in parallel to each other, the first inner cable being located at a first end of the plurality of inner cables, the second inner cable being located at a second end of the plurality of inner cables;

an outer casing surrounding the first coaxial cable, the second coaxial cable and the plurality of inner cables;

wherein the first coaxial cable is adjacent to the first inner cable and the second coaxial cable is adjacent to the second inner cable; and

wherein the first coaxial cable and the second coaxial cable are adapted to connect to an antenna and a base unit.

9. The cable of claim 8, wherein each of the first coaxial cable, second coaxial cable, and plurality of inner cables comprises a first end and a second end, the cable further comprising a shield connected to an end of at least one of:

the first coaxial cable;

the second coaxial cable; and

an inner cable.

10. The cable of claim 9, wherein the shield is a ferrite bead.

11. The cable of claim 10, wherein the ferrite bead is connected to a plurality of inner cables.

12. The cable of claim 8, wherein the plurality of inner cables is a ribbon cable.

13. The cable of claim 8, further comprising an inner cable shield surrounding the plurality of inner cables.

14. The cable of claim 13, further comprising an inner casing surrounding the plurality of inner cables and the inner cable shield, wherein the outer casing surrounds the inner casing and inner cable shield.
