A Finite Difference Time Domain Calculation for Rotationally Symmetric Ultrawideband Antennas

Abstract

A finite difference time domain (FDTD) technique for the analysis of ultrawideband (UWB) antennas with rotational symmetry has been developed. The theory is intended to treat various types of biconical antennas, and a mode matching analysis of spherically-capped bicones has been performed to verify the correct implementation of the FDTD calculation. In addition, experimental results have been obtained which are compared to the theoretical results. The FDTD software can be used for the design of high-power, directive UWB antennas with low sidelobe leakage for high-power UWB radar and electronic countermeasures applications.
