This paper presents the implementation and the effect of broadband matching in simultaneous information and power transfer. The narrowband characteristic of antennas limited the applications of simultaneous information and power transfer. The simplified real frequency technique (SRFT) and the non-foster matching technique have been presented to improve the performance in terms of channel capacity and power delivery. Electromagnetic simulation and multiobjective optimization are performed to analyze the tradeoff between the channel capacity and power delivery in different matching conditions. The performance gain using the matching networks have been demonstrated and analyzed
