Parametric Design and Simulation of a Biconical Antenna: Admittance, Directivity, and Far Field Radiation

The objective of this paper is to respond directly to the Project Authorization Request (PAR) for developing P2816: Recommended Practice for Computational Electromagnetics Applied to Modeling and Simulation of Antennas. A biconical antenna model provided as the specific example is simulated by Ansys HFSS electromagnetic solver based on Finite Element Method (FEM). HFSS is a full wave electromagnetic simulation tool available in ANSYS Electronics Desktop (AEDT) and can be used to predict how complex real-world geometries will perform as designed. The simulation results of this paper are compared to previously published and accepted theoretical analysis of a spherical capped biconical antenna.
