Compact Wake-Up Module Design Based on an Energy-Harvesting Rectenna for Wireless Sensor Receivers

Abstract EN

A new compact energy-harvesting module is proposed with compact design techniques.

The rectifying circuit eliminates the band-pass filter and matching circuit, based on an active antenna concept and a direct matching technique.

For exact circuit impedance, via holes are processed with precise fabrication techniques.

The implemented circuit has achieved a circuit size reduction of 76.7%.

The proposed system has been applied to a wireless wake-up receiver system with excellent operating performance.
