摘要
A radiofrequency exciter comprises a junction including an axial access intended to be connected to a horn antenna, at least four lateral accesses and at least four frequency filters that are associated with the four lateral accesses, respectively, the junction including, in series, a first coupling cavity equipped with two coupling slots that are able to sample a vertical polarization, and a second coupling cavity equipped with two coupling slots that are able to sample a horizontal polarization, the four frequency filters being connected directly to the four respective coupling slots, the first coupling cavity having a transverse cross-section having a constant vertical dimension and a horizontal dimension that decreases between the axial access and a transverse exit aperture of the first coupling cavity.
