摘要
为了找到角锥喇叭天线在主瓣某一范围内使场的相位保持相对恒定的等效相位中心,提出了一种确定角锥喇叭天线等效相位中心的分析方法。该方法通过采用角锥喇叭的简化模型对角锥喇叭天线远区辐射场进行分析,利用该移动参考点法计算和分析了角锥喇叭E面和H面的相位中心和等相位面宽度,得出了角锥喇叭的相位中心、等相位面宽度与等相位面的相位偏差之间的关系。
In order to determine the position of equivalent phase centers of pyramidal hom antenna, which keep the phase of the antenna＇s field relative invariable in some range of the antenna＇s main lobe, an approach to analyze the equivalent phase centers of pyramidal horn antenna is presented in this paper. Through analyzing the far field of the pyramidal horn using its simplified model, the E and H plane phase centers and their equiphase surface width of the pyramidal horn are analyzed and calculated by using the method of moving reference point, and the relationship of deviation of equiphase surface between the phase center and equiphase surface width is achieved.
