【摘要】 通过分析交指型左手微带天线结构参数对其辐射性能的影响,给出了适合交指型左手微带天线设计的参数范围。作为实例,设计了L波段交指型左手微带天线单元。与传统微带天线相比,在增益没有恶化的情况下,尺寸大为减小。最后,分别加工了交指型左手微带天线单元以及4×4交指型左手微带天线阵列,实测结果与仿真结果吻合较好,验证了本文提出的方法。更多还原

【Abstract】 Firstly,by analyzing the effects of parameters of interdigital left-handed microstrip antenna(ILH-MSA)structure on radiation performance,the ranges of parameters to ensure the performance of ILH-MSA are given.Then,an L-band ILH-MSA has been designed as an example.Compared with a traditional microstrip antenna(MA),the size of the present ILH-MSA is reduced largely.Finally,One ILH-MSA and a 4×4 ILH-MSA array are fabricated and measured.The good agreement between numerical and experimental results verified the present method.更多还原
