In recent years, global warming and environmental pollution raise a problem along with the increase in the carbon dioxide radiation by use of a fossil fuel. An SSPS (Space Solar Power Satellite) plan has been proposed as one of the solutions of these problems. Namely, a huge solar cell is carried on a geostationary orbit, electric power obtains from the sun, it changes and transmits to microwave, and there is a plan to use it again as electric power on the earth. Clean energy can be supplied without any weather conditions in a whole night and day. Lightweight, small, and beam control are demanded for SSPS realization. It is most important to generate the exact a microwave beam to the pilot signal transmitted from the receiving antenna side on the earth. In this research, Active Integrated Antenna (AIA) with a mixing system retrodirective function in a SSPS power transmission part, was demonstrated. It becomes the promising solution of the microwave beam control by uniting AIA with retrodirective technology. In this paper, examination of AIA with a mixing system retrodirective in SSPS is reported. The design and fabrication of a loop oscillator by mixing for the retrodirective function were performed. The output at 5.80 GHz was obtained with well-worked antenna patterns by mixing with the local oscillation frequency of 8.70 GHz and the pilot signal of 2.90 GHz.
