摘要: 該文利用譜域法分析了天線罩對(duì)天線方向圖的影響,計(jì)算了加天線罩后,天線一天線罩等效體輻射方向圖,得到了與實(shí)驗(yàn)結(jié)果相吻合的結(jié)論。并對(duì)某型機(jī)載吊艙干擾機(jī)中天線罩對(duì)天線方向圖的影響給出了定量說(shuō)明,為天線、天線罩設(shè)計(jì)提供了參考依據(jù)。

Abstract: In this paper, the effect of radome on antenna radiation with the spectral-domain approach is analyzed. Radiated pattern of antenna with radome is calculated, and the conclusion is got that the experimental results agree with the calculated. The quantitative analysis of the effect of radome on antenna radiated pattern is given and provide valuable basis for the design of antenna and radome. -
