摘　　要：针对天线极化特性如何在近场测量系统进行测试的问题,文中从实际工程应用出发,结合电磁场理论,基于椭圆极化波的分解理论,提出了利用线极化探头测量椭圆极化天线特性参数的方法。通过线极化探头进行两次正交的测量即可得到圆极化天线的方向图、轴比、倾角、增益等特性信息,也得到了线极化天线的交叉极化特性。In this paper, starting from practical engineering application, a method of near field measurement for antenna polarization is addressed by combining with the electromagnetic theory. Based on elliptical polarization wave decomposition theory, a method for measuring the character of elliptical polarization antenna using linear polari- zation probe is proposed. Though the orthogonal test using linear polarization probe we can get the character of circular polarization antenna, such as far field pattern, axis ration, tilt angle and gain tec. also get the cross polarization character of linear polarization antenna.
