这是关于偶极子天线的仿真程序。模型搭建合理，仿真结果包括电场、磁场、电压电流的分布图，还包括偶极子天线的磁场三维视图。-This is a simulation program on the dipole antenna. To build a reasonable model, the simulation results, including the electric and magnetic fields, voltage and current distribution maps, also includes a magnetic field three-dimensional view of the dipole antenna.
