Abstract
This paper presents numerical results for electromagnetic analysis of biconical antenna performed via Rao-Wilton-Glisson (RWG) Method of Moments (MoM) solution of the Electric Field Integral Equation (EFIE) in the mixed-potential form. The study is done as part of the IEEE P2816 Project entitled "Recommended Practice for Computational Elec-tromagnetics Applied to Modeling and Simulation of Antennas". Numerical results obtained with in-house RWG MoM code are compared against those generated using FEKO commercial MoM solver as well as analytic solution available for the biconical antenna. It is shown that upon δ-gap excitation mechanism at the port of the antenna the mesh density near the port effects the extracted input impedance of the antenna especially at high frequencies. Effect on the numerically extracted input impedance associated with the closeness of the computational model to the model of the ideal antenna is studied.
