| 摘 要： | 采用时域有限积分法（FIT）对相同几何口径尺寸下不同长度TEM喇叭天线的主轴辐射特性进行了研究，分析了有限长TEM喇叭天线与理想（无限长）TEM喇叭天线主轴辐射场存在差异的原因，导出了有限长TEM喇叭天线主轴辐射场在接近理想TEM喇叭天线辐射场条件下天线长度与激励脉冲宽度（或脉冲上升时间）之间的关系。在此基础上，根据文献中的研究结果，并结合激励脉冲波形，给出了TEM喇叭天线几何参数的优化设计方法。

| Abstract: | The finite-integration time-domain (FIT) method is adopted to calculate the radiaton fields on the boresight of TEM horn with various lengths, and the results are compared with the radiation field of infinitely long TEM horns. By analysing radiation field difference between finitely and infinitely long TEM horns, we derive the relation between horn length and pulse risetime. Based on the research in references, a optimized design method for parameters of TEM horn is presented. |
