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.
Keywords�� antenna arrays   monopulse antennas   slot antennas   slot lines   broadband antennas
