Abstract :
This work presents the design of a dual-band rectenna operating at 915 MHz and 2.45 GHz. The design of the rectifier is based on the concept of dual-band resistance compression network as the impedance matching network of the circuit. The 915MHz/2.45GHz rectifier exhibits a low sensitivity at different load and input power variations. Additionally, a dual-band antenna is designed and fabricated to operate at the same frequency bands. The electromagnetic energy harvester is evaluated for different power densities, showing a DC voltage of 293 mV and 79 mV for a load value of 1 kΩ and a power density of 1uW/cm2 at 915 MHz and 2.45 GHz, respectively.
