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。 The radiation principles of the metamaterial composite right/left-handed microstrip leaky wave antennas are analyzed in this paper,the simulation model of the metamaterial composite right/left-handed microstrip leaky-wave antenna is established and the radiation characteristics of the microstrip leaky-wave antenna are obtained by calculating the simulation results.The antenna has the same parameters with the simulation model is designed.The S parameters and the pattern of the antenna and the capacitive transient voltage of each unit are measured.Finally,the good agreement is obtained by the comparative simulation results and experimental results.At a fixed frequency,when the composite right / left handed metamaterials microstrip leaky-wave antenna operates in the left handed region,the electromagnetic wave radiated mainly in the first few units of the antenna,and it decayed rapid exponentially,when it operates in the right handed region,the electromagnetic wave radiated along the antenna and attenuate slowly.
