Characterization of compact disc UWB monopole antennas using the Singularity Expansion Method

This work employs the Singularity Expansion Method (SEM) to model a metallic monopole operating above a conducting ground plane followed by an analysis of printed circular disc antennas. To the authors knowledge, this is the first time that such a SEM analysis has been completed for these planar circular disc ultrawideband (UWB) monopoles. Complete characterization of this nature, in both the time and complex frequency domains, is important to ensure a robust design and valid UWB performance.
