摘　　要：以常规的微带天线为基础,开展基于人工磁导体(AMC)的天线单元研究,通过人工材料的使用提升天线辐射效率,改善天线带宽。依次研究加载人工磁导体的天线单元设计、尺寸分析、误差分析、网格地分析等,最终根据仿真结果完成一款2×2子阵的LTCC基板加工。对2×2子阵的测试结果表明加载人工磁导体结构有效展宽天线带宽并提升增益,证明加载AMC结构的天线具有高效率辐射特性。Based on the conventional microstrip antenna,the research on the antenna element based on artificial magnetic conductor(AMC)is carried out to improve the antenna radiation efficiency and antenna bandwidth through the use of artificial materials.The antenna element design,size analysis,error analysis and grid analysis of the artificial magnetic conductor are studied in turn.Finally,a 2×2 sub-array LTCC substrate is fabricated according to the simulation results.The test results of 2×2 subarray show that the artificial magnetic conductor structure can effectively broaden the antenna bandwidth and increase the gain,which proves that the antenna loaded with AMC structure has high efficiency radiation characteristics.
