| 摘要: |
| 为了解决标准卡氏天线的驻波特性差的问题，本文分析了副面母线为双曲线的环焦天线，给出了这种天线的最佳设计公式，并从能量守恒定理出发，导出了计算其方向图的简单表达式。利用文中所给的公式进行设计，可使天线获得良好的驻波特性。 |

| Abstract: |
| The ring focus antenna with hyperboloid for the subroutine is reviewed in order to solve the problem of bad VSWR of Cassegrain antenna. The best design formulas of the antenna is given. From the Law of conservation of evergy，a simple formula for calculating its radiation pattern is deduced. The antenna designed on the best design formulas has a good VSWR characteristic. |
