Abstract

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. The proposed reconfigurable filter can achieve a tuning range of its center frequency from 1.44 to 2.7 GHz, with a bandwidth from 110MHz to 400MHz. This filter design can enhance the flexibility and compatibility of SWIPT transmitters, which can communicate and energize more receivers and relays, thereby improving the efficiency of continuous transmission and optimizing spectrum utilization.
