AbstractA wireless power transmission experiment by microwave is conducted from an airship with an altitude of 30 m, for the first time in the world aiming at simultaneous transmission of power and information and technical verification of miniaturization and remote control of a wireless power transmission system. The microwave was transmitted from two elements of radial line slot antennas (RLSA) fed by phase controlled magnetrons with a frequency of 2.46 GHz and an output of 11O W. The airship is tied up at four points of the gondola. This is a retrodirective system that can transmit a beam to the direction of arrival of a pilot signal of 5.8 GHz sent from the ground. Two lithium-ion batteries of 28 V 30 AH are used as a power supply. The channel of 2.412 GHz was used for wireless LAN and a 429 MHz-band specified low power radio system was used for a backup telemetry and command network. The experiment was performed on March 5, 2009 from an altitude of about 33 m. The power transmission system operated normally. It was effective that the electronic buzzer connected to four-element 7 cm-square rectenna started to ring below the airship at the same time as the power transmission. Lighting of a charge lamp connected to a 12-element rectenna was also confirmed.
世界で初めて、飛行船(高度30m)から地上に向けて、マイクロ波による無線電力伝送実験を行ない、電力・情報同時伝送技術、無線電力伝送システムの小型化技術・遠隔操作技術に関する技術検証を行なう。移動体による災害時用ユビキタス電源システムのデモ実証、また、宇宙太陽発電衛星の実現に向けた一歩としても位置づけている。
