摘要: 提出了一种新近研制成功的结构紧凑的S~C波段新型的宽频带单脉冲天馈系统.其关键部件包括天线单元、宽频带魔T及宽频带功分器.通过对渐变槽线天线单元的分析和计算、天线阵列的分布及阵因子的计算、微带-槽线双重接头及其构成的魔T的研究,而获得了高增益的宽频带单脉冲天馈系统.天馈系统的实测结果与理论设计相吻合.Abstract: A wide-band monopulse antenna-feed system was developed by the authors. This wide-band monopulse antenna-feed system operates in S~C bands.Its key parts include the taper slot antenna, the wide band magic T and the wide band divider. By analyzing and calculating taper slot antenna and the factor of antenna arrays and studying microstrip-slotline junction and design theory of magic T, the antenna-feed system with wide-band and high gain was obtained. The validity of the design of the above antenna-feed system was verified by its agreements with experiment results.
