The method of electromotive force (emf) for calculation of antenna impedance is applicable to a very limited number of antenna configurations such as monopole and dipole antenna. In more general antenna structures, especially when complicated geometry such as fractals is involved numerical techniques are essential. There are Electromagnetic (EM) simulation softwares such as G-NEC, XFDTD for the modelling studies in which an understanding of the fundamental theory behind these numerical techniques in creating the antenna models is essential. In this paper, we compare the radiation from dipole antenna and the antenna with shape of the first iteration of Cantor set. The simulation of this problem has been done by COMSOL Multi-physics software.
