摘要
详细介绍了易于工程实现的赋形反射面天线设计方法。提出了一种俯仰面方向图预调技术。该技术可以通过预先调整目标方向图,有效弥补了传统方法设计出来的赋形反射面天线高仰角增益偏小的不足。同时,通过对反射面进行椭圆切割,在性能指标满足要求的条件下降低了天线尺寸、质量。
A method to design the shaped reflector antenna is introduced in detail,which can be easily applied in practice. The pre-compensation pattern technique in elevation is proposed,with which the target pattern is pre-adjusted to effectively compensate for the gain of high elevation angle compared to the conventional methods. Moreover,in the case of meeting the technical requirements,the antenna size and weight are reduced through elliptical cutting of the reflector.
