Abstract :
A 900 MHz low-cost flexible omni-directional rectenna with a mass of 2.1 grams is demonstrated. A rectenna as demonstrated here employs only a Schottky diode, a capacitor, and a printed coplanar circuit which presents class-F harmonic terminations to the diode, resulting in approximately 48.6% efficiency at a low 8 μW/cm2 incident power density. The rectenna is printed on 0.13 mm PET with a commercial printing process depositing 1 μm-thick conductive traces.
