摘　　要：对一种柱面电磁带隙结构应用于圆柱共形偶极子振基站天线进行了研究。结果表明,应用柱面电磁带隙结构后,基站天线辐射方向性有明显增加,在E面实现了更窄的波束,而H面保持了较宽的波束,符合对基站天线性能的要求。In this paper, a kind of cylindrical EBG structures applied to base station cylindrical conformal dipole array antennas is studied. The research results show that the directivity of base station antennas is significantly increased, a narrower beam -width is realized in E -plane and a wider beam -width is held in H -plane, which completely conform to the performance requirement for base station antennas.
