1. A radio-frequency phase shift assembly for coupling to a feed line, comprising:

  • at least first and second stripline sections which are arranged concentrically, said at least first and second stripline sections for coupling to at least two different pairs of antenna radiating elements driven with different phase angles (φ

    ) at mutually offset tapping points, a tapping element pivotable about a pivoting axis, the tapping element having a first tapping section for said first stripline section and having a second tapping section for said second stripline section, said first and second tapping sections being respectively pivotable over the associated first and second stripline sections and being coupled thereto, at least first and second connection lines, the tapping element being connected to said feed line such that the feed line is electrically connected via the first and second connection lines to the first and second tapping sections associated with said first and second stripline sections, wherein the tapping element comprises a pointer element which rotates about the pivoting axis, and wherein the second connection line is disposed with respect to the second stripline section by extending the first connection line which leads to the first tapping section.
