This paper presents the effect of broadband matching in simultaneous information and power transfer along with an implementation. The narrowband characteristic of antennas has limited the applications of simultaneous information and power transfer. The performance improvements in terms of channel capacity and power delivery under broadband matching have been demonstrated.
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 has been demonstrated and analyzed.
