Abstract
This paper presents a surface-assisted dual-frequency antenna architecture for simultaneous wireless information and power transfer (SWIPT) system designed for heterogeneous-sized devices. The system consists of a large transmitting antenna and a small receiving antenna, operating in dual resonance across 13.56 MHz and 300 MHz frequency bands. The low-frequency band enables efficient energy transfer, while the high-frequency band facilitates information transmission. To enhance transmission efficiency and link isolation, an intelligent metasurface (MTS) is introduced between the transmitting and receiving antennas. This design enables energy focusing and beam direction enhancement for signals across both frequency bands, thereby optimizing performance in both energy and information transmission. Simulation results demonstrate that this architecture achieves stable and efficient operation in both low-frequency energy transfer and high-frequency information transmission while significantly reducing mutual interference. The proposed dual-frequency SWIPT design not only resolves the applicability issues of traditional dual-frequency antennas in mismatched device configurations but also provides an efficient integrated energy and information transmission solution for IoT systems, smart city infrastructure, and medical implantable devices.
