A conducting device could either radiate or scatter Electromagnetic fields depending on the position of the external source feeding it. In either case, the Engineering parameters of the device can be determined by numerical methods. For linear structures, the Method of Moments is a typical approach that is applied for this analysis and is based on the formulation of the integro/differential equations of Pocklington’s or Hallen’s equation. The equations are described based on the choice of the Kernel in the numerical solution. In this paper, the implication of the kernel formulation for analysis of wire antenna, with emphasis on the approximate kernel is presented. The result shows the current distribution responsible for Electromagnetic radiation from an antenna and the difficulties associated with it.
