1. A power generation satellite comprising:
- a light condensing optical section for condensing sunlight in space;
a photoelectric conversion section for receiving light condensed in the light condensing optical section and generating electric energy;
a plurality of transmitters for generating microwaves from the electric energy generated by the photoelectric conversion section; and
a transmission antenna for sending the microwaves generated by the transmitters to space, wherein the transmission antenna comprises;
an array antenna having an element antenna for emitting the microwave; and
a reflecting mirror antenna for reflecting the microwave emitted from the array antenna.

Abstract
High-output transmitters are applied to a power generation satellite and a transmission antenna apparatus and a transmission antenna having an array antenna with a small number of element antennas and a reflecting mirror antenna is applied, thereby providing a power generation satellite and a transmission antenna apparatus in a space photovoltaic generation system comprising transmission antennas each having performance equivalent to that of a phased array antenna with a smaller number of transmitters and a smaller number of element antennas than those of a transmission antenna implemented as a phased array antenna.
