Abstract (in Japanese) (See Japanese page) 
(in English) Although microwaves leaking from a microwave oven can be converted into energy to light up the LEDs of resin accessories, it was difficult to light multiple LEDs at the same time. On the other hand, if the half-wave element of the Yagi-Uda antenna is changed to a loop-type element, the effect of waveguiding to the loop-type element is produced. However, if this is used as a rectenna, the LED will not light up because the rectifier circuit will be short-circuited. To overcome the issues, the novel C-type loop rectenna array with open loop elements is proposed. Based on the analysis, we made a prototype and succeeded in lighting multiple LEDs at the same time by arraying this rectenna.
