【Abstract】 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.更多还原
