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

A Compact Microwave Rectifier for Wireless Power Transfer and Energy Harvesting Applications
This paper presents a microwave rectifier with compact size and high efficiency for radio frequency (RF) energy harvesting and low-power internet of things (IoT) applications. The proposed rectifier consists of a matching network, a doubler rectifier, a lowpass (LPF) structure and a low-power electronic circuit.
