A compact fractal structure based rectenna with the rectifier circuit integrated

A compact rectenna using a microstrip patch antenna based on a fractal model and with the rectifier circuit integrated into the same physical structure has been designed and implemented. The proposed compact rectenna, implemented on a low cost FR-4 substrate, can harverst RF power from 2.4 GHz (ISM band) with a good efficiency (~48%). The suggested rectenna has been manufactured and experimentally characterized, showing a good agreement with the expected simulated results.
