| 摘 要： | 应用时域有限差分法(FDTD)对微带缝隙漏波天线进行分析,直观地得到了微带缝隙漏波天线内部的电场分布。提出了一条有效的经验公式,成功地计算了微带缝隙漏波天线的漏波传播系数,与实验数据吻合较好。比较了不同缝隙宽度和微带宽度对微带缝隙漏波天线性能的影响。证明了在微带漏波天线上开缝可以有效地减少天线尺寸及降低天线的工作频率。

| Abstract: | The FDTD method modeled the micro-slotline leaky wave antenna successfully.The traveling wave of micro-slotline leaky-wave antenna in leaky region had been shown up with FDTD method.A new and effective equation was proposed,to calculate the complex propagation constant of micro-slotline leaky wave antenna.The numerical result calculated by the new and efficient method agrees well with measured results and comparing data.Based on the model of FDTD and the novel equation,the character of micro-slotline leaky wave antenna is shown up.The numerical result points out that the width of micro-slotline leaky-wave antenna affect character of antenna.Based on it,that is a new way to make main lode scan at fix-frequency. |
