Bandwidth and Efficiency enhancement by multiport loading of a double notched small antenna is presented in this paper. The technique used is based on the combination of the Network Characteristic Modes (NCM) with an optimization algorithm, in order to find the optimal load values at specified positions. The required loads are found to be simple capacitive loads.
