Abstract :
This letter presents a novel X-band planar rectenna (i.e., a rectifying antenna). The proposed device consists of a slot antenna and a microstrip rectifying circuit. A realization on a low-cost FR4 substrate, using a surface-mount Schottky barrier diode (the HSMS-8202 diode by Avago Technologies) as the rectifying element, is proposed. Measurements performed at 9.3 GHz demonstrate that an RF-to-DC conversion efficiency of about 21% can be obtained with an input power density of 245 μW/cm2.
