본 발명은 급전 장치로부터 이동체에 무선으로 전력을 공급할 때 전력의 낭비를 저감할 수 있는 이동체의 구조를 제공하는 것을 목적 중 하나로 한다. 또한, 사방으로 방사되는 전파의 강도를 낮게 억제할 수 있는 이동체의 구조를 제공하는 것을 목적 중 하나로 한다. 이동체에 전력을 공급하기 전에 안테나의 위치를 맞추기 위한 전파를 급전 장치로부터 출력한다. 즉, 급전 장치로부터 2단계에 걸쳐 전파를 출력한다. 1단계째의 전파는 급전 장치와 이동체가 각각 갖는 안테나의 위치를 맞추기 위하여 출력된다. 2단계째의 전파는 급전 장치로부터 이동체에 전력을 공급하기 위하여 출력된다.

    An object is to provide a moving object structure capable of reducing power loss caused when power is supplied from a power feeding device to a moving object by wireless communication. Another object is to provide a moving object structure capable of reducing the strength of a radio wave radiated to the surroundings. Before power is supplied to a moving object, a radio wave for alignment of antennas is output from a power feeding device. That is, radio waves are output from a power feeding device in two stages. In a first stage, a radio wave is output to align positions of antennas of the power feeding device and the moving object. In a second stage, a radio wave is output to supply power from the power feeding device to the moving object.
