The field of antennas is vigorous and dynamic and over the past fifty years, antenna technology has been an indispensable partner of the communication revolution. There is a plethora of antennas and antenna elements, many of which exhibit intricate configurations. With the advent of super fast computers, numerical solution techniques are adapted extensively to analyze the problems with different boundary conditions and complex geometries. Over the past few years, there has been an increased reliance on Finite Difference Time Domain (FDTD) and Finite Element Method (FEM) for the characterization of electromagnetic problems.
