Ku/E-band dual-frequency integrated feed source

The invention relates to a Ku/E-band dual-frequency integrated feed source, which is characterized in that the dual-frequency integrated feed source comprises a dual-frequency radiation part and a feed part, wherein the middle of the dual-frequency radiation part is provided with an E-band dielectric rod horn and a dielectric loaded feed waveguide; a corrugated horn wraps the E-band dielectric rodhorn to form a radiation part of the Ku-band; the E-band feed consists of a circular moment conversion structure, the Ku-band feed consists of a coaxial quadrature mode coupler, the coaxial quadrature mode coupler consists of four branched waveguides, and two waveguides separated apart 180 degrees are connected by a power divider. A coaxial feed design scheme is adopted, a coaxial cavity realizesthe radiation of Ku-band dual-linearly polarized electromagnetic waves, and the E-band dielectric rod horn is embedded into the inner core of the coaxial structure as a feed source, thus realizing radiation of E-band single-l
