反射面天线设计的关键就是通过选择合适的喇叭馈源边缘照射电平以追求天线的高性能(增益,旁瓣电平,效率等)。本文主要利用实例验证了标准反射面天线馈源喇叭的优选边缘照射电平,分析了赋形反射天线馈源喇叭的优选边缘照射电平,给出了标准反射面和赋形反射面在设计中各自馈源喇叭的优选边缘照射电平。从而可以在设计工作中对于不同形式的反射面天线有针对性的设计馈源喇叭的边缘照射电平。
Reflector antenna design is the key by selecting the appropriate speaker feed edge illumination level in pursuit of the antenna’s high performance (gain, sidelobe level, efficiency, etc.). In this paper, we mainly verify the optimal edge illumination level of a standard reflector antenna feed horn by using an example. The optimal edge illumination level of the feed horn of a profiled reflector antenna is analyzed. The design of the standard reflector and the reflector is given The preferred edge illumination level of the respective feed horn. Thus, it is possible to design the edge irradiation level of the feed horn for the design of different types of reflector antennas.
