A Flexible printed dual-band antenna dedicated to RF Energy Harvesting Application

A flexible printed dual-band dipole antenna, operating at 900 MHz and 2.44 GHz, is developed and fabricated using low cost fabrication process. The antenna acts as a receiving antenna and is connected to a 4-stage RF-DC converter manufactured on FR4 substrate. The assembled RF Energy harvester is tested in a wireless power transfer scenario. In dual-band configuration, the harvester provides a 1V DC voltage for a power density of 0.7 mW.m-2 at 900 MHz and 1.1 mW.m-2 at 2.44 GHz.
