摘要： 通过对Ｈａｌｌｅｎ方程进行矩量法求解，讨论了十字交叉振子类型天线产生圆极化辐射时两对振子长度选择的方法；计算了几种情况下天线的远区辐射场；指出十字交叉振子、伞型振子等这类天线由于具有结构紧凑、工作可靠、易于赋形等特点，可广泛应用在空间飞行器上。

Abstract: y the Hallen equation's solution, a method of forming crossing dipoles circular polarization antennas from choosing the length of dipoles is given in this paper.The equation is solved by moment method. The computed and measured circular polarization antennas' patterns are also given. Because of the simple and reliable structure, this sort of antennas can be used widely in spacecraft.
