An Analysis of the Characteristics of Corrugated Horn for Feeding Beam-waveguide Antenna

빔 웨이브가이드 안테나의 급전을 위한 원뿔형 컬러게이트 혼의 특성 해석

The characteristics of the corrugated conical horn antenna for the satellite communication earth station operating at C band is analyzed and its radiation patterns is measured. We obtain the characterstic equations for corrugated horn in the condition that the balanced hybrid mode is formed on born aperture and calculate radiation patterns in the Fresnel region from the aperture integral expressions obtained by the equivalence principle. The radiation patterns which are calculated for the frequency of 3.85GHz and 6.18GHz are well agreed with the measured data.
