Abstract
The frequency behavior of the first characteristic mode along a thin plate was presented. For this structure, the first mode retained the shape of its resonant current distribution below resonance but significant changes were seen above resonance. The rectangular planar monopole was analyzed, and tapering the monopole near the feed point was found to enhance the match with the feed. For each monopole width, a taper angle was identified to give the best match.
