Development of a rectenna for batteryless electronic paper

This paper describes the design of a rectenna for batteryless electronic paper. The rectenna is composed of a one-sided directional flexible antenna and a booster rectifying circuit that is composed of a series resonant circuit and a Cockcroft-Walton circuit. The proposed one-sided directional flexible antenna has a bottom floating metal layer that enables one-sided radiation. The booster rectifying circuit has an output of 3.5 V DC for an input of 200 mV and a 50-Ω power source at 920 MHz.
