Abstract :
A single-shunt rectifying circuit is often used as a receiver for wireless power transfer. This type of circuit can theoretically rectify microwave input at 100% efficiency with only one diode due to the enhancing effect of the output filter. In this paper, we indicate the role of the output filter composed of a diode and a capacitor connected in parallel to a distributed line through ADS simulation. In addition, we indicate the optimum parameters of the single-shunt rectifying circuit to increase the radio frequency-direct current conversion efficiency.
