| 摘 要： | 基于几何绕射理论,计算了位于导体圆柱上的单极子天线和惠更斯元面天线的辐射方向图;利用该方向图,分析比较了不同天线之间的隔离随天线指向的变化情况。结果表明:选择适合的天线类型及适合的安装角度能够改善天线间隔离度;几何绕射理论是解决导电圆柱体上天线的辐射问题的一种有效方法;应用远区辐射场的方向函数估算耦合系数是一种简单可行的方法。

| Abstract: | Based on GTD,patterns of monopole and planar antenna located on a conducting cylinder are computed.The coupling coefficient of different antennas are compared and analyzed.The results show that the coupling coefficient can be improved by choosing right antennas and suitable degree.For solving the problem of radiation antenna located on a conducting cylinder,it is a good way to use GTD.It is feasible to use antenna pattern to estimate coupling coefficient. |

| Keywords: | geometry detour radiation theory antenna pattern coupling coefficient meridian plane |
