Highly cost effective antenna for use in a satellite interactive terminals

摘要

FIELD: antenna assemblies for interactive satellite terminals.;SUBSTANCE: proposed antenna assembly has main elliptical parabolic reflector and corrugated horn feed with external elliptical aperture, as well as internal cylindrical waveguide with internal section and stepped section. Newly introduced in stepped section are resonator components to compensate for cross-polarization components.;EFFECT: enhanced efficiency and reduced manufacturing cost of antenna.;6 cl, 9 dwg
