1·Through analysis of sensor using the antenna model, it indicates that the radius and down-lead length of a disc coupler can influence frequency response characteristics.

对研制的内置圆板传感器建立天线模型进行分析表明，圆板天线半径和引线长度对圆板天线频率响应特性有很大影响。

2·According to induction and the work of authors, the potential applications in perfect lens antenna, phase-shifting line, balancer and coupler were given.

依据归纳法并结合作者的工作提出了开展此项研究在理想透镜天线、相移器、平衡器、耦合器等应用。

3·Some microstrip structures such as microstrip line, patch antenna and microstrip branch line coupler have been simulated and the characters of these elements have been analysed.

利用FDTD法分别对微带传输线、矩形微带贴片天线和微带分支耦合器进行了仿真和特性分析。
