摘要
为精确设计某型散射通信天线,采用高频电磁仿真软件(HFSS)仿真设计反射面天线的馈源结构,然后对馈源的远场进行拟合、插值,并结合一致性绕射理论(UTD)计算整个天线的方向图。通过对天线的实测,结果吻合较好,说明该混合法对此类天线的分析精度高、速度快,在工程设计中有很大应用空间和前景。
In the design process of some scatter communication antenna, the feed is simulated and devised with high frequency simulation software （HFSS）. The far field property of feed is fitted and interpolated, and the directivity pattern of the whole antenna is calculated combining uniform geometrical theory of diffraction （UTD）. Through measuring the practical antenna, the results are consistent well, which proves that the hybrid method is of great precise and high speed in the analysis of this kind of antenna. And the method shows a tremendous application space and prospect in the engineering design.
