Convergence Properties of Higher Order Modeling of the Cylindrical Wire Kernel

Extensive analysis of wire antennas using method of moments (MoM) has been performed over the past decades. Despite the thorough understanding and widespread use of the wire antennas, higher order modeling of wire structures has received little to no attention over the years. This may be because the inaccuracies associated with the classic reduced kernel approach used to analyze wire antennas have precluded the use of higher order basis functions. This paper combines a new method for computing integrating the cylindrical wire kernel with higher order basis functions for the accurate modeling of wire antennas. Numerical results demonstrate the higher order convergence of the approach
