摘　　要：通过在微带线上加载交织结构和短路肢节构建出宽频带左右手传输线并将其应用于宽频带液体介电测量；分析并通过仿真对比验证了左右手传输线相对于右手传输线在测量灵敏度上的优势；给出了传感器设计过程以及验证性实验结果，证明该传感器可以在1．5GHz-7．In this paper,the mierostrip line loaded interdigital structure and short segments to construct the wide band of left and fight hand transmission line and its application in broadband liquid dielectric measurement;analysis and simulation results show that the left and fight hand transmission line is superior to the fight-handed transmission line in the measurement on the sensitivity of the sensor;the design process and experimental results given that the sensor can get the measurement sensitivity is higher than the fight hand transmission line sensor in the range of 1.5GHz -7.0GHz

关 键 词：介电常数 左右手传输线 交指结构 短路肢节
