摘要
本文设计了一种基于人工电磁结构的平面宽带高增益圆极化天线。天线采用平面宽带磁电偶极子天线作为馈电结构,工作在Ku波段,辐射左旋圆极化波。通过在磁电偶极子天线上层加载人工电磁结构,天线在保证圆极化轴比特性基础上,在整个Ku波段上增益提高了3.2d B-5.8d B。结果显示,加载人工电磁结构可以进一步提升天线的增益和方向性。通过HFSS软件仿真优化参数,天线具有良好的阻抗和增益带宽,在卫星通信系统中具有很好的应用价值。
This paper proposed a plane broadband high-gain circular polarization antenna based on artificial electromagnetic structure. The antenna employs plane broadband magnetic-electric dipole antenna as feed structure, works in Ku wave band and radiates left-handed circular polarization wave. Through mounting artificial electromagnetism structure on magnetic-electric dipole antenna, the gain increases 3.2d B-5.8d B on the whole Ku wave band without affecting the AR bandwidth. The results show that mounting artificial electromagnetic structure can further improve the gain and directivity of antenna. Through parameters optimization of HFSS software simulation, the antenna possesses good impedance and gain band width and has great application values in satellite communication system.
