    摘要: A disk-shaped reflecting plate 3 for reflecting an electric wave emitted out of an aperture 1a of a circular waveguide 1 is placed a location which is just opposite to the aperture 1a of the circular waveguide 1, and a ring-shaped waveguide 4 for shaping the radiation characteristic of the electric wave reflected by the disk-shaped reflecting plate 3 to a rotational symmetrical radiation characteristic is disposed around the perimeter of the disk-shaped reflecting plate 3. Thereby, even when many grooves 4a need to be formed in order to make the electric wave have a rotational symmetrical radiation characteristic, it is not necessary to increase the size of the disk-shaped reflecting plate 3 in the direction of its radius.

    摘要: A space photovoltaic generation system including a plurality of power satellites arranged in space, each of which converts electrical energy, into which sunlight has been photoelectric-converted, into a microwave, and transmits the microwave to an electric power base. The system can thus transmit a microwave of high power to the electric power base. Each of the plurality of power satellites modulates the generated microwave so as to generate an incoherent microwave before transmitting it to the electric power base, thus reducing the power density of the electric power transmitted to the electric power base on the earth and hence a loss in the total amount of energy transmitted to the electrical power base on the earth.
