摘要
本文以微分几何为工具,应用一致性几何绕射理论(UTD),导出了有限长金属圆锥柱侧天线三维辐射场的计算公式。这些公式同样适用于有限金属圆柱或圆锥。应用上述公式计算了锥柱侧横向缝隙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。
A formula is developed to calculate 3-D radiation field of antennas on the finite truncated cone- cylinder by applying the UTD and differential geometry. These formulas are also applicable to the finite truncated cone and cylinder. Examples are given on the calculations of 3-D radiation patterns of circumferential slots on the finite truncated cone-cylinder. The results of calculations agree well with the experimental ones.
