Self-supporting stripline RF transmission cable
View Patent ↗A stripline RF transmission cable has a flat inner conductor surrounded by a dielectric layer that is surrounded by an outer conductor. A jacket with an attachment feature surrounds the outer conductor. The attachment feature may be a fin aligned parallel or normal to the inner conductor. The attachment feature may be continuous or periodic along a longitudinal extent of the cable. The attachment feature may include male and female portions dimensioned to couple with one another, enabling adjacent cables to be attached to one another.
1. A self supporting stripline RF transmission cable, comprising:
a flat inner conductor extending between a pair of inner conductor edges;
the inner conductor surrounded by a dielectric layer;
an outer conductor, with a generally hourglass cross section, surrounding the dielectric layer, wherein the dielectric layer is a continuous layer between the inner conductor and the outer conductor; and
a jacket surrounding the outer conductor;
the outer conductor provided with a top section and a bottom section; the top section and the bottom section provided spaced farther away from each inner conductor edge than from a midsection of the inner conductor;
the jacket provided with an attachment feature.
2. The cable of claim 1 , wherein the attachment feature is a longitudinal fin extending from the jacket one of parallel and normal to a horizontal plane of the inner conductor.
3. The cable of claim 2 , further including periodic slots in the fin; the slots aligned normal to a longitudinal axis of the cable.
4. The cable of claim 1 , wherein the attachment feature is a fin loop between a first location proximate the top section and a second location proximate the bottom section.
5. The cable of claim 1 , wherein the attachment feature further includes a reinforcing layer.
6. The cable of claim 5 , wherein the reinforcing layer is encapsulated within the attachment feature.
7. The cable of claim 1 , wherein the attachment feature is a male portion and a female portion provided on opposite sides of the cable; the male portion and the female portion dimensioned to couple with one another.
8. The cable of claim 1 , wherein the attachment feature is continuous along a longitudinal extent of the cable.
9. The cable of claim 1 , wherein the attachment feature is periodic along a longitudinal extent of the cable.
10. The cable of claim 1 , wherein the attachment feature is at least one clip with a protrusion; the clip coupled to the outer conductor and at least the clip encapsulated by the jacket.
11. A self supporting stripline RF transmission cable, comprising:
a flat inner conductor extending between a pair of inner conductor edges;
the inner conductor surrounded by a dielectric layer; and
an outer conductor, with a generally hourglass cross section, surrounding the dielectric layer, wherein the dielectric layer is a continuous layer between the inner conductor and the outer conductor; and
a jacket surrounding the outer conductor;
the outer conductor provided spaced farther away from each inner conductor edge than from a midsection of the inner conductor;
the jacket provided with an attachment feature.
12. The cable of claim 11 , wherein the attachment feature is a longitudinal fin extending from the jacket one of parallel and normal to a horizontal plane of the inner conductor.
13. The cable of claim 12 , further including periodic slots in the fin; the slots aligned normal to a longitudinal axis of the cable.
14. The cable of claim 11 , wherein the attachment feature is a fin loop between opposite sides of the cable.
15. The cable of claim 11 , wherein the attachment feature further includes a reinforcing layer.
16. The cable of claim 15 , wherein the reinforcing layer is encapsulated within the attachment feature.
17. The cable of claim 11 , wherein the attachment feature is a male portion and a female portion provided on opposite sides of the cable; the male portion and the female portion dimensioned to couple with one another.
18. The cable of claim 11 , wherein the attachment feature is continuous along a longitudinal extent of the cable.
19. The cable of claim 11 , wherein the attachment feature is periodic along a longitudinal extent of the cable.
20. The cable of claim 11 , wherein the attachment feature is at least one clip with a protrusion; the clip coupled to the outer conductor and at least the clip encapsulated by the jacket.
