Abstract

A junction (300) for connecting two waveguides having an angular offset between longitudinal symmetry axes of their cross-sections and a first linear offset of the center axes of the waveguides. The junction (300) comprises at least a first and a second transformer sections (202, 206) both having said first angular offset between longitudinal symmetry axes of their cross-sections and said first linear offset of their center axes, wherein each of said transformer sections (202, 206) has one protruded ridge (204, 208) on broad walls, wherein the first ridge (204) is mainly situated outside the cross section of the second transformer section 206 and the second ridge (208) is mainly situated outside the cross section of the first transformer section (202).
