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 .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.
