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.
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。
