Active integrated amplifier antenna arrays for a space solar power satellite

Abstract

In this paper, as one of the examples of an application of an active integrated antenna technique, a design method and experimental data of the active integrated amplifier antenna array were reported for microwave power transmission in the space solar power satellite 2000 system. The stacked structure of a unit cell in the array proposed here consists of three layers: the amplification circuit layer, radiation layer, and coupling layer. By incorporating 2×2 unit cells with the combination of a directional coupler and an FET amplifier, a light unit patch plate with weight of 200g.
