摘要
将天线长度看作矢量,运用电场强度矢量与天线长度矢量之间的点乘,计算单杆天线的感应电动势。通过建立空间坐标系,将电场强度矢量与天线长度矢量进行分解,再运用矢量点乘规则,得到天线上的感应电动势。理论公式推导表明,将天线长度看作标量计算得到的单杆天线的感应电动势的结果,与将天线长度看作矢量计算得到的单杆天线的感应电动势的结果是一样的。因此,将天线长度看作矢量,运用矢量点乘规则来计算感应电动势的方法是可行的。
The antenna length is considered as a vector, and the induced EMF (electromotive force) of a single-rod antenna is calculated by the point multiplication between the electric field strength vector and the antenna length vector. By establishing space coordinate system, the electric field strength vector and the antenna length vector are decomposed, and then the vector point multiplication rule is used to obtain the induced EMF on the antenna. The theoretical formulas show that the induced EMF of a single-rod antenna calculated by taking the antenna length as a scalar is the same as that calculated by taking the antenna length as a vector. The experiment results indicate that it is feasible to calculate the induced EMF by taking the antenna length as a vector and using the vector point multiplication rule.
