Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents experimental studies on the improvement of RF-DC conversion efficiency of the small-sized rectenna using an LC resonator having high-Q characteristics at 950 MHz. By choosing an optimum LC combination, the RF-DC conversion efficiency of 85.6 % at a 10-mW input power has been attained. Furthermore, at a low input power of 1 mW and 0.1 mW, the RF-DC conversion efficiency of 73.2 % and 40 % has been achieved. Using the developed rectenna, experiments on long distance wireless power transmission were performed, and its ability to transmit power to distant wireless devices in an actual fading radio wave propagation environment was confirmed.
