Reconfigurable Microwave Filter for Simultaneous Wireless Information and Power Transfer [PDF]

2025 IEEE Wireless Power Technology Conference and Expo (WPTCE)
This work presents a novel design approach for a reconfigurable filter with two resonance points, enabling a wider tuning range and improving spectrum utilization for simultaneous wireless information and power transfer (SWIPT) transmitters. A T-shaped structure is used to control two resonant points to control the change in the passband of the filter.
