| 摘 要： | 传统端射天线是中等增益天线，不能满足雷达等对高增益的要求。为了提高增益和方向性，把平板端射天线单元进行了组阵。经过大量的仿真分析并结合原有试验结果，发现了平板端射天线的组阵不符合常规天线组阵理论。端射天线阵的增益随着天线单元间距的增大而提高，并且间距在1．5倍波长时天线阵的增益最高。这种特殊的天线组阵形式值得进一步研究。

| Abstract: | In this article,new characteristics of plate end-fire antenna are found.In order to increase gain and directivity,plate end-fire antennas are arrayed.By the combination of simulation and previous results,this kind of array is found to be inconsistent with the theory of antenna arrays.In order to get high directivity,the space of the array should be increased and best result can be got on 1.5 wavelengths,and this kind of structure needs further analysis. |
