采用旋转体时域有限差分法（FDTD）分析了由波导激励介质球馈电的介质管天线。为了获得高增益，管稍微张开。结果表明，喇叭形结构在12 GHz时的增益约为23 dBi，高于均匀结构。
A dielectric tube antenna fed by a waveguide-excited dielectric sphere is analyzed using the body-of-revolution FDTD method. To obtain a high gain, the tube is slightly flared. It is found that the flared configuration achieves a gain of approximately 23 dBi at 12 GHz, which is higher than that of a uniform configuration.
