摘要
圆极化微带天线是一种低剖面的天线元,研究圆极化微带天线的特性在天线设计中显得十分重要,而微带贴片天线的馈电位置的确定是设计的关键。针对单端侧馈五边形圆极化微带天线进行了详细分析和论述;简要介绍了微带天线的实现方法,并介绍了一种用于分析多边形微带天线的有效方法———有限元分析法;通过对一个5.6GHz的五边形圆极化微带天线的研究设计,给出了圆极化微带天线的设计过程,找到了确定馈电点位置的合理方法,采用HFSS软件进行优化设计,进行仿真,给出了合理的仿真结果。
The circular polarization microstrip antenna is one kind of low cut plane antenna element . Researching circular polarization microstrip antenna property is very important in antenna design. And how to find the feed place is the key to design. Researching makes a detailedly analysing and expounding of the pentagon circular polarization microstrip antenna in view of the single ended side. The microstrip antenna realization means is introduced. The way to analyze polygon microstrip antennal is given, which is named finite cell. By adjusting the 5.6 GHz pentagon circular polarization microstrip antenna, we give out the circular polarization microstrip antenna design processing. The feed place is found with the right means. Adopting HFSS software to optimize the design , and carries on imitation , give out the right imitation result .
