Abstract (en)
[origin: US2017104271A1] A horn antenna, able to propagate signals in a spectrum of frequencies B1, . . . , Bi, . . . , BN, B1 being the lowest frequency band, Bi being at least one intermediate frequency band and BN the highest frequency band, comprises a side wall axisymmetric about a longitudinal axis Z, an axial access orifice, termed throat, and a radiating aperture, the side wall comprising annular corrugations. The horn antenna further comprises four coaxial probes diametrically opposite in pairs. The four probes are inserted into a specific, dedicated corrugation, the four coaxial probes being spaced apart at equal angles in a plane perpendicular to the longitudinal axis Z and entering the longitudinal axial conduit of the horn antenna. Each coaxial probe is designed for the propagation of signals in the lowest frequency band B1 of the spectrum.
