| 摘 要： | 天线增益很大程度上决定了天线的整体性能,用传统的方法提高天线增益需要付出很大的代价,而电磁带隙结构(EBG)的提出使高性能天线的设计和制作成为可能.文章采用新的紧凑叉型EBG结构来设计天线.仿真和实验结果均证明,加载EBG结构以后天线的增益提高,说明了电磁带隙材料的引入可以有效改善原有天线的性能,同时紧凑的结构更易于实现小型化的天线,这对实现高效紧凑的天线阵具有重要意义.

| Abstract: | The performance of antenna was dependent greatly on its gain,but in conventional method,it toke large cost to improve the gain,however,the recently developed electronic bandgap(EBG) structure made the possibility of designing and machining antenna with higher performance.A novel compact fork-like EBG structure was employed to design patch antenna.The simulated and measured results showed that EBG material was efficient in improving the characteristic of antenna,and the proposed EBG structure was convenient ... |
