Design and Optimization of Single-Shunt Diode RF Rectifier Using Electromagnetic Co-Simulation

In this paper, an efficient design process for a single-shunt diode RF rectifier is proposed. The technique focuses on tuning microstrip line sections in electromagnetic and circuit co-simulation. The design study can achieve an RF-to-DC conversion efficiency of 51.27% at the center frequency of 950 MHz with -10 dBm input power. Good agreement between full wave electromagnetic simulation and electromagnetic/ circuit co-simulation is demonstrated, providing substantial support for the proposed RF rectifier design technique.
