Abstract

A differential phase shifter assembly with n striplines positioned concentrically with one another, on the opposite stripline ends of which connecting points for connecting lines leading to radiators are provided, where n is a natural integer greater than or equal to 2. A feeding and/or tapping device is pivotable about a central and/or pivot axis, and is therefore pivotable over the plurality of striplines while establishing a primary capacitive coupling. A central feed serves to feed the feeding and/or tapping device. At least one to n−1 secondary capacitive couplings are additionally provided. The one or more secondary capacitive couplings are provided on the side of the feeding and/or tapping assembly facing the primary capacitive coupling. For the at least one additional secondary capacitive coupling, at least one additional branched feeding and/or tapping device is provided, which together with the feeding and/or tapping device is pivotable about the central and/or pivot axis.

Claims (20)

1. A differential phase shifter assembly comprising:

n striplines arranged concentrically with one another, on the oppositely located stripline ends of which connection points are provided for connecting lines leading to radiators, where n is a natural integer greater than or equal to 2,

a feeding and/or tapping device which can be pivoted about a central and/or pivot axis and which is therefore pivotable over the plurality of striplines while establishing a primary capacitive coupling,

a central feed which feeds the feeding and/or tapping device,

at least one secondary capacitive coupling and a maximum of n−1 additional secondary capacitive couplings,

the at least one or the plurality of secondary capacitive couplings is/are provided on the side of the feeding and/or tapping device opposite the primary capacitive coupling, and

for the at least one additional secondary capacitive coupling at least one additional branched feeding and/or tapping device is provided, which together with the feeding and/or tapping device is pivotable about the central and/or pivot axis.

2. The differential phase shifter assembly according to claim 1 , wherein the at least one additional branched feeding and/or tapping device is mechanically and electrically connected to the feeding and/or tapping device, either capacitively or galvanically.

3. The differential phase shifter assembly according to claim 1 , wherein the secondary capacitive coupling has a first secondary coupling surface formed on the feeding and/or tapping device, which cooperates with a second secondary coupling surface, which is formed by the section of the stripline overlaid by the first secondary coupling surface at a distance therefrom, whereby an insulator, in the form of a fixed insulator, which is affixed to the branched feeding and/or tapping device or is held by it, is provided between the first and secondary coupling areas.

4. The differential phase shifter assembly according to claim 1 , wherein the branched feeding and/or tapping device includes an angular attachment which mechanically holds the branched feeding and/or tapping device is on the feeding and/or tapping element and electrically feeds it.

5. The differential phase shifter assembly according to claim 1 , wherein the branched feeding and/or tapping device includes a holding attachment or an indicator head which is situated in the area of the central and/or pivot axis parallel to an indicator head of the feeding and/or tapping device, and is mechanically held and galvanically or capacitively fed together with the indicator head.

6. The differential phase shifter assembly according to claim 1 , wherein only a single additional secondary capacitive coupling is provided, by which an additional capacitive coupling is established only with regard to a single one of the plurality of striplines.

7. The differential phase shifter assembly according to claim 1 , wherein the branched feeding and/or tapping device has m coupling surfaces, which with m striplines establish an additional capacitive coupling, where m>1 and m<n.

8. The differential phase shifter assembly according to claim 1 , wherein the at least one branched feeding and/or tapping device is so constructed and positioned to establish at least one secondary capacitive coupling to a stripline closest to the central and/or pivoting axes.

9. The differential phase shifter assembly according to claim 8 , wherein the at least one branched feeding and/or tapping device is so constructed and positioned to establish at least two capacitive couplings with at least two adjacent stripline.

10. The differential phase shifter assembly according to claim 1 , wherein the at least one branched feeding and/or tapping device is so constructed and positioned to establish at least one capacitive coupling to the second or farther outwardly situated stripline, viewed from the central and/or pivot axis.

11. The differential phase shifter assembly according to claim 1 , wherein at least two consecutive primary capacitive couplings with respect to the feeding and/or tapping device and/or at least two consecutive secondary capacitive couplings with respect to the branched feeding and/or tapping device are connected via a line section, which has a material section differing from the associated coupling surface and/or a differing width extent in the pivot direction.

12. The differential phase shifter assembly according to claim 1 , wherein with respect to two adjacent striplines on the additional branched feeding and/or tapping device, at least one additional secondary capacitive coupling is provided for each.

13. The differential phase shifter assembly according to claim 1 , wherein the additional branched feeding and/or tapping device runs over at least one stripline, forming a coupling-free or minimally coupled zone, and that at least one secondary capacitive coupling is provided which is farther away from the central or pivot axis with respect to the coupling-free or minimally coupled zone.

14. The differential phase shifter assembly according to claim 1 , wherein at least two additional secondary capacitive couplings are provided, and that these at least two additional secondary capacitive couplings are held on a joint additional branched feeding and/or tapping device which carries them, whereby these at least two additional secondary capacitive couplings are allocated to two non-adjacent striplines, so that the additional branched feeding and/or tapping device runs over at least one coupling-free or minimally coupled zone) with respect to a stripline located between the two secondary capacitive couplings.
