A small UWB circular monopole antenna with a differential feed is presented in this paper, as a solution to increase the stability of the radiation pattern of a single-fed circular monopole antenna. A detailed characteristic modes analysis is presented in order to support the selection of the feeding mechanism. Simulated active-S parameter is shown for the proposed antenna, showing a good matching for the UWB frequency range. Normalized surface current distributions are presented, and 3D radiation patterns are compared to a reference monopole. The antenna structure shows more stable and omnidirectional radiation patterns over the studied frequency range compared to a same sized single-fed reference monopole.
