Analysis and Design of Dual-Band Rectifier Using Novel Matching Network

In this brief, a compact dual-band impedance matching network is introduced and applied to the design of rectifying circuits. The matching network can work at two arbitrary frequencies with arbitrary complex impedance simultaneously. Theoretical analysis is carried out and the closed-form design for...

Zusammenfassung:In this brief, a compact dual-band impedance matching network is introduced and applied to the design of rectifying circuits. The matching network can work at two arbitrary frequencies with arbitrary complex impedance simultaneously. Theoretical analysis is carried out and the closed-form design formulas are derived. For validation, a dual-band rectifier working at 0.915 and 2.45 GHz is implemented. The measured maximum RF-to-dc efficiencies are 77.2% and 73.5% at 0.915 and 2.45 GHz, respectively.
