Abstract

A junction (100) for connecting two waveguides (102, 104) having a first angular offset (α) between longitudinal symmetry axes of their cross-sections, said junction (100) comprising a first interface and a second interlace for connecting said waveguides (102, 104). The junction further comprises at least a first transformer section (106) and a second transformer section (108), both having cross-sections of substantially rectangular shape, and both having said first angular offset (α) between longitudinal symmetry axes of their cross-sections. Each of said transformer sections (106, 108) has two protruded ridges (202, 204, 206, 208) on its opposite walls.
