Abstract (en)
[origin: CA3065566A1] An RF joint rotating about an axis of rotation (Z) comprises a number N, greater than or equal to 1, of RF transmission channels, a first, internal surface of symmetry of revolution about the axis (Z) and of RF transmission having a first, internal radius r1, and a second, external surface of symmetry of revolution about the axis (Z) and of RF transmission having a second, external radius r2, strictly less than said first, internal radius r1. The first and second RF transmission surfaces facing one another and rotationally mobile about the axis (Z) are configured through the first and second radii r1, r2, the geometry of the first and second RF access ports, and the geometry of the first and second RF containment and guidance means, such that: - each RF transmission channel Vi, i varying from 1 to N, comprises a first RF rotating waveguide, and - the N first RF rotating waveguides are distributed angularly over a predetermined number NC, greater than or equal to 1 and less than or equal to N, of sections of surfaces of revolution about the axis (Z) of the second RF transmission surface, each of the NC sections being situated along the longitudinal axis of symmetry (Z) at a predetermined different level L1(k).
