Abstract
Three types of parabolic antenna to reduce the sidelobes and backlobe are compared to determine the best suppressive effect under same conditions which are side rim loading parabilic antenna, flanged prabolic antenna. The hooded parabolic antenna adhered polyurethan form impregnated carbon powder in shows the best shape of suppressed the side back lobes that is 5 to 10 dB suppression of sidelobe and 15dB suppression of back lobe for E-plane.
周邊端裝苛 拗物形 空中線과 水兵形 테두리附着 拗物形 空中線 및 후드附着形 拗物形 空中線等 세가지 形態의 拗物形 空中線을 同一條件下에서 製作하여 側葉 및 後葉特性을 比較하였다. 側葉 및 後葉의 抑制效果가 가장 優秀한 것은 후드 內部에 炭素粉末 混入 포리우레탄 스폰지를 內한 것을 附着한 것으로 E面上에서 側葉에 5내지 10dB, 그리고 後葉 15dB 效果를 얻었다.
