Electromagnetic Compatibility Analysis of Plane Antennas

摘要: 假定飞机腹部加装了某一形状的炮舱和矩形喇叭天线,用时域有限差分法(FDTD)分析了这样的外形对天线辐射特性的影响.通过对机身和天线之间不同相对位置下天线辐射特性的分析,得出了机载天线方向图的一些规律.Abstract: On the assumption that a cabin and a horn antenna were under the bottom of an airplane, FDTD method was applied to analyze the antenna patterns which are generally affected by the body of the airplane. By adjusting the relative positions between the body and the antenna, some interesting results were obtained, which are suggested to be useful for a reasonable distribution of the plane antennas.
