摘　　要：利用折叠导电墙结构可以有效减小微带天线的尺寸,展宽辐射波束。对折叠导电墙结构进行改进,将导电墙分解为3部分,各个部分分别加工完成后,进行装配组合,并加载到微带天线。改进后的导电墙结构的加工费用远小于一体化折叠导电墙。在L1频段设计加载改进导电墙的右旋圆极化微带天线结构,Ansys HFSS软件仿真结果和实测数据表明,所设计的天线仍具有小尺寸和宽波束的优点。By using a folded conducting wall,the size of the microstrip antenna can be reduced and the beamwidth of the radiation pattern can be expanded.A new type of folded conducting wall is designed to decrease the manufacture difficulty and homologous costs.And a wide beamwidth right hand circularly polarized microstrip antenna based on this new type of the folded conducting wall is designed at L1 band.The simulation and measurement results show that this antenna has the advantages of small size,wide beamwidth and low cost.
