Device comprising: two identical quadrature couplers, (14) and (15), a rotary gyrator (1) disposed between the two couplers, (14) and (15), and a fixed gyrator (13) disposed between the two couplers, (14) and (15), which can be disposed one on each coupler interconnection branch or both on the same branch. The rotary gyrator comprises: an internal rotary disk (2), having a groove gap that defines a waveguide, a housing, wherein the rotary disk (2) is housed, means for actuating the rotation of the rotary disk and means for radially and axially centering the rotary disk (2) on the housing. The practical application of the device relates to the manufacture of switchable polarisation antenna feeders, enabling the configuration of an orthomode transducer for either linear polarisation or circular polarisation. |
