Abstract :
We designed and fabricated the rectennas which use class-F load as an output filter in order to develop highly efficient rectennas at 24 GHz and 60 GHz. We also fabricated conventional rectennas which use a capacitor as an output filter, and compared the efficiency of class-F load rectennas with that of capacitor rectennas. We selected the diode which can produce high efficiency even at high frequency, and we parallelized the diode to improve the efficiency. The experimental result of efficiency of class-F load rectennas was 65.6%, on the other hand, that of capacitor rectennas was 52.1%.
