Analysis of near field problem of standing wave antenna with dipole antenna as an example. In the calculation of antenna near field, far field radiation pattern of the traditional no longer applies, the right solution is the antenna for multiple segments according to certain rules division, using moment method to calculate the current distribution of each piece, and then according to the current distribution to determine the near field intensity distribution. The rigorous solution of the current distribution on the antenna is a very complicated theoretical problem. For the simple structure of the antenna, the structure of the antenna is a good and uniform transmission theory to determine its current distribution.
