Abstract (in Japanese) (See Japanese page) 
(in English) In the OHISAMA project, mission payload instruments are being developed for an on-orbit demonstration of long-distance wireless power transmission technology using a small satellite. The experiment employs a phased array transmitting antenna with a size of 2 m × 0.75 m. We are conducting functional and performance evaluations of the antenna through both numerical analysis and experimental measurements. This presentation reports on the RF evaluation tests carried out at the AMET Laboratory of Kyoto University.
