| 摘 要： | 提出一种低造价的卫星电视平板接收天线，并给出该天线的设计公式．该天线的扁平主反射器呈波纹结构，可用很薄的铝板冲压成型．根据扁平主反射器的特点，与之配合的副反射面采用环焦原理设计．曾研制了一个小口径的Ｋｕ波段试验天线．实测结果表明天线效率大于６０％．

| Abstract: | A low-cost flatplate antenna is presented for the reception of TV broadcasting from satellite, and the designing formulas of the antenna are given. The flat main reflector of the antenna assumes a corrugated shape, which can be made of a very thin aluminum plate. And, it applies theory of ring-focus to the design of subreflector. A small aperture antenna has been made for Ku band. The experimental results show that the efficiency of this antenna registers higher than 60% |
