摘要
The invention relates to a source (1) for a reflector antenna, comprising: - a pseudo-cavity (100), - a first sigma excitation device (10) for exciting the pseudo-cavity (100) in such a way as to generate a sum channel signal via a coaxial waveguide (400), - a second excitation device (20) for exciting the pseudo-cavity (100) in such a way as to generate a difference channel signal, the second device (20) comprising eight probes (8) angularly distributed around a principal emission axis (A) of the source (1), and a difference supply circuit (25) for supplying the eight excitation probes (8) according to the two modes TE21.
