| 摘 要： | 在传统圆极化天线的基础上,设计了一种宽带四元组合圆极化微带天线,采用双层电磁耦合馈电结构,不仅拓宽了阻抗匹配带宽,而且有效改善了天线的圆极化轴比特性。经过计算和测试,天线工作于Ku波段时,阻抗带宽和3dB轴比带宽分别达到了26.4%(VSWR<2)和8.64%。这种结构的圆极化天线在卫星通信等领域应用前景广阔。

| Abstract: | Based on the conventional circular polarization antenna,a broadband circular polarization microstrip antenna fed by electromagnetic coupling is designed,which is composed of four cells and dual dielectrics.Through the antenna,the frequency band is broadened not only,but also the circular polarization axial ratio is effectively improved.Through calculation and testing,the 26.4%(VSWR<2)impedance bandwidth and 8.64% 3 dB axial ratio bandwidth are achieved respectively.Such a circular polarization microstrip antenna can be used extensively in satellite communication. |
