摘要
文章根据偏置卡塞格伦天线设计原理,通过双馈源、副反射面的正反面将两种不同结构的偏置卡塞格伦天线结合在一起,研究出一种双馈源-单副反射面-双主反射面的新型偏置卡塞格伦天线。该天线充分利用了偏置双反射面天线的扫描特性好、可避免遮挡效应等优点,在两个不同方向上产生双波束,实现双方向扫描,拓宽了卡塞格伦天线的应用领域。
According to the design principle of the offset Cassegrain antenna, a dual-feeding offset Cassegrain antenna is designed by combining the double kinds of offset Cassegrain antennas. It makes use of the characteristics, such as scanning and decreasing the sheltering effect of offset dual reflector antenna. Its advantage is to produce double beams in double different orientations and scan double different space domains.
