antenna a current的意思|示意

In this paper, a new method is presented for the calculation of surface current distribution and far region radiation field of the short backfire antenna.

本文提出一种用于分析和计算短背射天线表面电流分布和远区辐射场的方法。

Indeed, that is how a radio antenna works, except that the weak current generated by the radio waves has to be amplified to do its job of carrying a signal round a radio.

而收音机的天线就是这样工作的，只不过电波所产生的电流非常弱，需要进一步放大从而完成信号传输。

To make a seawater antenna, the current probe (an electrical coil roughly the size and shape of a large doughnut) is attached to a radio’s antenna jack.

为制作一根海水天线，电流探针（一种电子线圈，尺寸跟形状大致相当于一个大炸面圈）要连接到一副无线电天线端子上。

In such a device, the antenna would concentrate photons before the photovoltaic cell converts them to an electrical current.

在具有纳米天线的光伏设备中，纳米管天线可以将进入光伏设备且没有转换成电流的光子集中起来。

Continuous resistive loading is used to extend antenna operating band in order to realize traveling-wave current distribution on a finite length antenna.

在有限长的偶极天线上，采用分布电阻加载法，实现行波电流分布，展宽天线的工作频带。

With the plane Archimedean spiral antenna a calculation of the current on the antenna as well as its radiation is carried out and its frequency independence was verified.

并以平面阿基米德螺旋天线为例，计算了天线上的电流分布和辐射特性，验证了天线的频率无关特性。
