偶极天线在圆波导中的辐射

Radiation from Dipole Antenna in a Circular Waveguide

本文采用并矢格林函数和场量变换方法,给出了圆形波导中偶极天线辐射的普遍公式。波导是半无限长的,端面反射系数为Γ。天线的长度、馈电点和取向都是任意的。作为例子,我们给出了四种特殊情况下的场量表示式。

The general formulas of radiation from dipole antenna in a circular waveguide are given by means of dyadic Green's function and field transformation. The waveguide length is semi-infinite. The reflection coefficient at the terminal plane is (?). Length, feeding point, and orientation of the antenna in the waveguide are all arbitrary. As examples, the expressions of field for four specific cases are given and discussed.
