摘要
应用电偶极子的场公式计算了线电流元和面电流元的近区场，并给出了应用准则．计算线天线近场时，采用线性插值技术，并与国外软件ＮＥＣ２ 进行了比较，指出了文中方法在计算近场时的优越性．求解面电流元近区场时，将二维问题转化为一维问题，避免了烦琐的坐标转换过程．
Near zone fields of linear current units and surface current patches are calculated by using field formulations of the electric dipole. Rules for correct applications are also given. The linear interpolation technique is used in solving the near fields of thin wire antennas. The advantage of this method over NEC2 is presented after a comparison between them. By using the technique presented here, a two dimensional problem is converted into one dimensional one and tedious coordinates transformation is avoided when one calculates the near zone fields of surface current patches.
