摘要: 根据实测的单元天线方向图,利用几何绕射理论,给出了金属截锥柱侧天线三维辐射场的一种有效的数值分析方法。这些公式同样适用于金属截柱或截锥。应用上述公式计算了截锥侧微带天线及其排阵的任意平面方向图,并与实测结果进行了比较,两者吻合良好。Abstract: On the basis of the experimental element pattern and GTD, an efficient numerical method for analyzing 3-D radiation field of antennas on the truncated cone-cylinder is presented. These formulas are also applicable to the truncated cylinder and cone. Examples are given on the calculation of 3-D radiation fields of microstrip antennas on the truncated cone. The results of calculations agree well with the experimental ones.
