Abstract
This paper presents a differentially driven planar monopole antenna for UWB (Ultra-Wideband) applications. The dimensions of the antenna structure are first studied to achieve wideband characteristics with good impedance matching. The goal is to find dimensions which satisfy the UWB demands but also to show that antenna size can be miniaturized by using differential feeding. The −10 dB impedance matching of the presented antenna structure starts from 1.3 GHz and simulations are performed up to 12 GHz. Normalized surface current distributions are presented and 3D radiation patterns are compared to a reference monopole. The antenna structure shows more stable and omni-directional radiation patterns over the studied frequency range compared to a same sized single-fed reference monopole. The antenna structure is finally scaled to the UWB bandwidth.
