【摘要】 本文根据球面近远场变换理论,采用球面波展开的方法,通过MATLAB编程实现了球面近场测量数据的近远场变换。应用HFSS软件设计仿真了一个工作在10GHz的喇叭天线,对HFSS仿真得到的喇叭天线的近场数据应用本文中的算法,变换得到了喇叭天线的远场方向图,并与由HFSS直接得到的喇叭天线的远场仿真数据进行对比,两者结果吻合良好,说明了该算法的正确性。更多还原

【Abstract】 A matlab algorithm for the near-to-far field transformation of spherical near field data is proposed in this paper.The algorithm based on the theory of near field to far field transformation,using the spherical wave expansion method.A horn antenna which is working on 10 GHz has been designed by HFSS,apply the near field HFSS simulation data of horn antenna to the algorithm,the far field pattern is obtained.And compare with the far field simulation data of horn antenna which obtained by HFSS directly,the results are in good agreement,which proves the validity of this algorithm.更多还原
