Abstract
In order to improve the sidelobe precision in PNF,two new H-plane probe patterns were used in the near-to-far field transformation.The results were analyzed and compared with other two traditional H-plane probe patterns.An array antenna was measured in anechoic chamber.Two traditional methods which are Stratton-chu integral and the E-field integration method and two new methods which are the fringe current and the fringe current approaching method were used in the near-to-far field transformation.The results indicate that the sidelobe precision achieved by the two new methods is close to the international advanced level and is much higher than present level at home.Also,the method is proved to be practical.关键词
