AbstractOur modern life is supported by massive energy consumption. At present, oil and gas have become the main energy sources. When these fossil fuels are wasted, a massive amount of CO2 is generated. Therefore, this problem becomes a hot topic. In order to develop power generation from a clean energy source such as the solar power, the SSPS has been studied since end of the 60th. Many groups have been established to develop make and promote the specialized technology for SSPS. One of them has taken charge of the development of the spacetenna (the transmitting antenna of the SSPS system). Key task of the development of the spacetenna is realization of a light and multi-functional antenna and transmitter system. One of promising candidates to satisfy the requirement of the spacetenna is the technique of an active integrated antenna (AIA) that consists of a planar antenna and an integrated circuit. Utilizing nature of the AIA, the authors have fabricated the prototype AIAs, and have developed a thin, light, high-power and functional transmitting antenna for the spacetenna. For instance, the configuration of the active integrated antenna was proposed in the functional-layer fashion, which consists of the amplification circuit layer, the coupling layer, the radiation layer and so on. To realize the two-dimensional array using the fundamental structure mentioned above, the combination of an FET amplifier and a directional coupler in the circuit layer was adopted to provide the equi-phase as well as the equi-amplitude to each antenna element. In this report, a design, a trial production, and evaluation of 5.8 GHz antenna array, or a phase shifter and an amplifier are shown by making the information acquired from the made prototype into a source. AIA with more sufficient electric power efficiency than the last prototype was able to be made by this.
