Abstract—In this paper, the analysis of an UWB monopole antenna using the Theory of Characteristic Modes is presented. The antenna was designed using a low-profile vertical monopole element with a standard metallic reflector plane. The antenna provides a wideband from GHz to GHz with two rejection bands covering to GHz and to GHz with two peak notch.
