Abstract
The invention relates to a device for rotating through a predefined angle the polarization of a polarized electromagnetic wave propagating in a first waveguide. According to the invention, the device comprises a second waveguide having a lateral port, the polarized electromagnetic wave propagates between a port of the first waveguide and the lateral port of the second waveguide via a coupling orifice that is smaller than the cross-section of the first waveguide and whose geometry is adapted to provide electromagnetic coupling between the first waveguide and the second waveguide, and the other port of the second waveguide is on a face perpendicular to the lateral port.
