Abstract
In this paper, the shaped offset Cassegrain antenna with low sidelobe, low cross-polar level, and high efficiency is designed. The design data is presented for shaping scheme. The validity of radi-ation characteristics is accomplished by comparing the result of measurement with numerical calculation and design goal. Experimental results of designed antenna are in good agreement with design goal except efficiency.
本 論文에서는 사이드로브가 낮고 交叉偏波 特性이 우수하며 동시에 效率이 높은 鏡面 修整 카세그레인 안테나를 最適 設計하고 試作했다. 設計를 위하여 設計 데이터를 提示했으며, 試作안테나의 輻射 特性은 側定 結果를 解析 結果 및 設計 目標値와 化較함으로써 그 妥當性을 檢討했다. 試作안테나의 實驗 結果는 效率만 제외하고 設計 目標値에 근접한 것으로 나타났다.
