Space photovoltaic power generation system, portable small power electronic machine, reception antenna apparatus, and electric power system

摘要

A power generation satellite converts electric energy generated from sunlight into a microwave and spreads and applies the microwave through a power transmission antenna of the power generation satellite to any desired area widely on earth. The beam width of the microwave is determined by the aperture area of the power transmission antenna placed in the power generation satellite. To spread and apply the microwave to a wide area, the power transmission antenna provided in the power generation satellite need not be a very large antenna having a diameter of several km or more like a power generation satellite power transmission antenna in a space photovoltaic power generation system in a related art.
