It's beneficial effect is purely a result of the way it prevents one's finger from touching the antenna's feed point, solving the impedance mismatch issue.
这种度量作用可以阻止手指接触到天线的馈点，从而解决阻抗失配的问题。
The feed point location of the SIS chip has little effect on the embedding impedance, while the chip thickness obviously does. These results will benefit the development of waveguide SIS mixers.
SIS结芯片馈点的位置对嵌入阻抗没有太大的影响，但芯片厚度的影响非常明显。这些结果对超导SIS混频器的研制有很好的指导意义。
