| 摘 要： | 文章论述了定向高增益圆极化微带天线阵的设计方法。以工作频率为2．45GHz的32单元圆极化微带天线阵为研究对象，设计出了与馈电网络为一体、圆极化特性良好且具有定向高增益的微带天线阵，从而解决了圆极化微带天线阵馈电网络较为复杂、工程实现较为困难这一问题。实验结果表明该天线阵具有良好的定向性和圆极化特性，达到了20．5dB的增益，进而说明了该方法是有效可行的。

| Abstract: | A design procedure for directional circularly polarized micro-strip antenna array is given.By designing an array composed of 32 circularly polarized antenna elements at 2.45GHz,a proper method for designing such an array with integrated feeding network and directional high-gain was given,and the conundrums such as complicacy of the feeding network and difficulty in realization are solved.Measurements are also carried out,which indicate the validity of this method. |
