Two quarter-wavelength short stubs are implemented to reflect all 2nd harmonics with an enhancement of 3rd-harmonic generation.

In this paper, a compact coupler-rectifier-receiver (CRR) system is proposed to address the problems inherent in these conventional techniques. Due to the intrinsic non-linearity of diodes, high-order harmonics are generated as part of the rectification process. Instead of eliminating these harmonics, the proposed structure couples the 3rd harmonic to its isolation port and used it for data recovery. The proposed method is validated by both simulation and measurement. The measured RF-to-DC conversion efficiency (PCE) is over 40% for input powers from - 11 dBm to - 1 dBm and reaches a maximum value of 57.3% at - 4 dBm. Simulation results on 3rd harmonic detection verify its potential for data recovery.
