C波段高增益圆极化微带天线阵的研制

Development of a C-band High-Gain Circular-Polarized Micro-strip Antenna Array

论述了圆极化微带天线阵的设计方法。以工作频率为5.8GHz,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、具有圆极化特性的微带天线阵,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圆极化特性,进而说明了该方法是有效可行的。

In this paper, a design procedure for circularly polarized micro-strip antenna array is given. By designing an array composed of 32 circularly polarized antenna elements at 5.8GHz, a proper method for designing such an array with integrated feeding network was given, and the conundrums such as complicacy of the feeding network and difficulty in realization are solved. Measurements are also carded out, which indicate the validity of this method.
