Abstract
L-matching networks have been proposed for boosting the power efficiency of radiofrequency (RF) energy harvesters. This paper shows that power efficiency is maximized by fine-tuning the components of the L-matching network and the load. Simulations at 868 MHz with commercial components and a Rogers substrate resulted in maximum power efficiencies of 10.9 %, 30.7 %, and 55.2 % for input powers of -30 dBm, -20 dBm, and -10 dBm, respectively. Experimental results showed efficiencies of 31.8 % and 5...
