对探头H面方向图，国内使用的E面电场积分法，在天线的远区副瓣引入较大误差。针对这种情况，提出一种新的基于边缘电流逼近法的探头方向图应用。通过在微波暗室对某频段天线进行实验测试，分别用国内传统的E面电场法与新方法进行计算比较。结果表明，此方法大大的改善了副瓣精度，基本达到了国际先进水平，为国内高精度测试打下了坚实的基础。%H-plane pattern of probe are generally obtained by using E-plane electric field integration method;however this method would introduce greater error to far-zone side-lobe of antenna. A new probe pattern meas-urement method based on fringe current approaching is proposed and applied. An antenna operating at some band is tested in anechoic chamber, and test results obtained by using conventional E-plane electric field method and the new method are compared. The result indicates that application of the method can significantly improve the preci-sion of side-lobe, performance of the method can be up to advanced international level, the method laid a good foundation for high precision measurement in China.
