Super-Broadband Rectifier with Wide-band Resistance Compression Network and Harmonic Cycling for RF-Harvesting

In this paper, a super-broadband (SBB) rectifier using a wideband resistance compression network (WRCN) and harmonic cycling is proposed, simulated, fabricated, measured and analyzed in detail for the harvesting of ambient radio frequency (RF) energy. Meanwhile, impedance compression and matching are achieved to implement the SBB using WRCN and cycling structure and bending technology are employed to improve the power conversion efficiency (PCE) and type of the proposed rectifier is fabricated and measured. simulated ones, indicating that the rectifier can provide high efficiency and ultra-broadband rectification characteristics. A PCE over 50% is realized at 3.5 GHz with an input power range of 6-24 dBm, and a PCE of 75% in the development of RF-harvesting.
