摘　　要：利用印刷天线制作精度高、一致性好的优点,结合对数周期天线具有超宽频带的特性,详细研究了单层印刷对数周期天线的分析与设计方法。在一般对数周期天线设计方法的基础上,考虑介质基板的影响,给出了印刷振子的长度、间距和宽度的修正设计方法,对单层印刷对数周期天线建模,并采用时域有限差分方法进行了分析,计算结果与实验结果吻合较好,验证了分析与设计方法的有效性。Using the advantages of the printed antennas, such as high precision and high consistency, combine the charac- teristics of ultra wide band of the log - periodic antenna, the analysis and design method of the monolayer log - periodic antenna are studied. On the basis of the design of log - periodic antenna, the analysis and design method of the printed log - periodic antenna are presented. The numerical results are compared with the experimental results,and the comparison shows excellent agreement over a wild angle range.
