Abstract (en)

[origin: EP0898323A2] The polarisation device has a hollow waveguide section supplied with two linearly polarised waves for two different frequency bands, coupled to two rectangular waveguides for each frequency band. The waveguides are offset from one another in the axial direction of the hollow waveguide section. The rectangular waveguide for the higher frequency band is divided into two flat rectangular arms (18, 19, 24, 25) joined to the hollow waveguide section at diametrically opposing points.
