“…The Schottky diode is a preferred diode in rectification due to the minimal energy required to operate. For example, a standard diode uses 0.6 − 1.7V to operate, while the Schottky diode only requires a 0.15 − 0.45V, yielding a faster switching speed [40], [41]. Literature has often relied on the use of the Skyworks SMS7630 diode [13], [21].…”

The conversion efficiency of a harvesting component can hinder device self-sustainability. Countering this inefficiency can be a rigorous task that requires either a modified input waveform at the harvesting component or an improved design of the harvesting component itself. This paper considers a selective orthogonal frequency division multiplexing (OFDM) system that is designed for simultaneous wireless information and power transfer (SWIPT). This paper introduces an enhanced transmitter architecture designed to condition the transmit signal for improved conversion efficiency. Leveraging the structure of the OFDM signal, the cyclic prefix plus a portion of the information signal are conditioned and used for harvesting. Then, a rectifier model and prototypes are designed to further improve conversion efficiency. System performance is evaluated with the analytical derivation of the rate-energy (R-E) tradeoff and an optimized transmission strategy for system self-sustainability. Monte Carlo simulations show increased energy gains and full self-sustainability with the introduction of signal conditioning.

“…First, the diode's equivalent impedances were measured at the expected frequency range (2.0 -2.8 GHz) as shown in Figure 7. The fundamental impedance is of importance since the front end is a tuned circuit and the "harmonic impedances" are filtered out in the application [8].…”

This paper introduces an overview of a rectifying antenna (rectenna) circuit topology for microwave power transmission system. Specially, a rectenna based on a microstrip patch antenna and a microwave double voltage rectifier at 2.45GHz were designed and fabricated. The antenna’s return loss is achieved of -15 dB at 2.45GHz. The microwave to DC conversion efficiency of the rectenna was measured as 71.5% with 22 dBm input power and 810 Ohm load. The design and simulated results were carried out by the microwave engineering professional design software, known as ADS2009 package. All design and simulation results will be reported.
