A wideband fractal rectana for energy harvesting applications
Résumé
The design of a wideband fractal slotted ground plane antenna with a dual-linear polarization is presented. The geometry of the slot is shaped as a Koch fractal of third generation. The proposed antenna was designed and optimized to operate between 1.5 and 2.65 GHz. A single series-diode topology rectifier was developed and associated to the design for rectenna achievements. Both antenna and rectenna were fabricated and experimentally characterized. The simulated and measured results show good agreement. Experiments show more than 1 V output voltage and 70 % efficiency.
