“…Finally, Table 2 summarizes a performance comparison among previous rectifier designs published in the literature [25,26,27,28,29,30,31]. For a fair comparison, only passive rectifiers that operate with an input power close to 0 dBm (1 mW) were considered.…”

This work presents some accurate guidelines for the design of rectifier circuits in radiofrequency (RF) energy harvesting. New light is shed on the design process, paying special attention to the nonlinearity of the circuits and the modeling of the parasitic elements. Two different configurations are tested: a Cockcroft–Walton multiplier and a half-wave rectifier. Several combinations of diodes, capacitors, inductors and loads were studied. Furthermore, the parasitics that are part of the circuits were modeled. Thus, the most harmful parasitics were identified and studied in depth in order to improve the conversion efficiency and enhance the performance of self-sustaining sensing systems. The experimental results show that the parasitics associated with the diode package and the via holes in the PCB (Printed Circuit Board) can leave the circuits inoperative. As an example, the rectifier efficiency is below 5% without considering the influence of the parasitics. On the other hand, it increases to over 30% in both circuits after considering them, twice the value of typical passive rectifiers.

“…The two orthogonal polarized ports can be used to receive information and energy, respectively. Various single-band rectennas for the ISM band (2.45 GHz) have already been investigated in [15][16][17]. In general, single-band rectifiers can be used to realize high efficiency easily.…”

A dual-band microstrip rectenna for wireless local area network (WLAN) applications is presented. It consists of a dual-band dual-polarized receiving antenna and a dual-band high efficiency rectifier. The receiving antenna includes a circular loop, a coplanar waveguide (CPW), and a microstrip line. To minimize mutual interference and ensure high isolation of more than 20 dB between the dualpolarized ports, a CPW is used to produce vertical polarization modes, and the horizontal polarization modes are fed by a microstrip line. The horizontal excitation port is used for information receiving, while the vertical feeding port transfers enough wireless energy for rectifying. A co-simulation of HFSS and ADS is used for analysing the performance of rectenna. Measured results show that it has the −10 dB reflection coefficient bandwidths of 510 MHz (2.39-3.09 GHz) and 920 MHz (5.16-6.08 GHz) for rectifying Port 1, where the isolation between the ports is higher than 25 dB, and the cross polarization is less than −15 dB in two bands. The maximum microwave-direct current (mw-dc) conversion efficiencies of 67.7% and 57.03% at 2.45 GHz and 5.8 GHz are achieved with a 300 Ω load and 16 dBm receiving power.
