摘　　要：从工程实际出发,提出了在口径耦合微带天线贴片周围加销钉的天线模型,以抑制表面波的损耗。并且在FDTD分析方法的基础上,构造出2个特殊盒子来计算远区辐射场。用所提出的模型和分析方法对Ku 波段12 GHz口径耦合微带天线进行了扫描研究。为工程实际应用提供了具有一定参考意义的图形及数据。In order to inhibition consumption of surface wave, the antenna model that the dowels were added surrounding the patch of the antenna was put forward from the view of engineering practice. Based on the method of FDTD, two special boxes were constructed to calculate the far area radiation field. Using the model and the analysis methods mentioned above, the study on K u wave band 12 GHz Aperturecoupled Microstrip antenna was carried on. The paper provided some meaningful sketch and the data for engineering practice.
