摘要 提出了一种基于一维电磁带隙(EBG)结构覆层来提高圆波导天线增益的新方法,利用数值分析方法对EBG结构和基于EBG结构圆波导高增益天线的电磁特性进行了仿真研究,并将它们与传统圆波导天线进行了比较。仿真和实验结果表明,应用这种EBG覆层结构可以有效地实现辐射能量的聚集,从而提高天线的增益,降低了天线副瓣电平,有效地改善了天线的辐射特性。 A new method of improving the gain of circular waveguide antenna is presented. The electromagnetic characteristics of EBG and high-gain circular waveguide antenna with 1-D EBG structure are studied by using the numerical sim ulation method, which are also compared with those of the conventional antenna. The simulation and experimental results show that this method is effective and the EBG structure can realized congregating the radiation energy, so the gain of the antenna is increased , the side lobe level is decreased.
