[电] ground plane
- 接地面虽能解决地线阻抗的问题，但不是万能的。
Ground planes solve many ground impedance problems, but not all. - 一定要使用电路板带有内置接地面，可容纳的空间，安装2或3的仪表。
Be sure to use a circuit board with a built-in ground plane, and to accommodate room for mounting 2 or 3 of the gauges. - 计算了倒L天线与凹形接地面之间的静电容和天线的输入阻抗，与实验结果吻合良好。
The static capacitance between the inverted L antenna and the concave surface and the antenna input impedance are computed, which are in good agreement with the experimental results.
