heal.abstract	Previous works have discussed in detail the difficulties occurring when one applies numerical methods to Hallén's and Pocklington's integral equations for the current distribution along a linear antenna. When the so-called approximate kernel is used, the main difficulty is the appearance of unphysical oscillations near the driving point and/or near the ends of the antenna. Another work has proposed an easy-to-apply, possible method to overcome these unnatural oscillations. The basic idea is to define a new current from the near magnetic field produced by the original oscillating current. In the present paper, for the case of an antenna center-driven by a delta-function generator, we place this remedy on a much firmer basis. ©2010 IEEE.	en
