Investigation of Radiation Characteristics for Metamaterial Microstrip Leaky-Wave Antennas

摘要: 分析复合左右手特异材料微带漏波天线的辐射原理,建立复合左右手材料微带漏波天线仿真模型,通过仿真计算得到微带漏波天线的辐射特性。制备与仿真参数相同的实物天线,测量天线S参数、方向图和天线各单元电容瞬态电压。最后,对仿真试验结果和实物天线测量结果比较,吻合较好。在固定工作频率下,复合左右手特异材料微带漏波天线工作在左手区时,电磁波辐射主要发生在天线结构前几个单元,且电磁波以指数形式快速衰减,工作在右手区时,电磁波沿整个天线辐射,且电磁波衰减较慢。
