摘要
介绍了一种新型的圆环形微带天线 ,它不同于一般的圆环形微带天线 ,它的内表面镀了一层金属 ,通过选择馈电点的位置可以轻易实现匹配 ,克服了一般圆环形微带天线输入阻抗太大不易匹配的缺点。最后 ,做出了一些实验天线进行测试 ,发现上下壁间距较小时 ,理论和实践能很好地吻合 ;当上下壁间距过大时不容易做到匹配。文中分析了上下壁间距过大不易匹配的原因 ,并且提出了下一步工作的思路。本文提出的设计这一类天线的方法和理论 。
In this paper, a new type annular antenna is designed. The antenna differ with usual antenna, its inner cylindrical wall is metallized and the feed point can be easily chosen to have an easy matching. It overcome the disadvantage of common annular antennas uneasy matching. Finally, some experiments verify the consistency between the results of theoretical computation and experimental one when the height between the top and bottom of the antenna is small. But it can not be matched easily as the height too large. The reason of difficult matching as the height too large is analyzed and the next work idea is put forward.
