Abstract :
In this paper, as one example of an application of the active integrated antenna technique, a design method and experimental data of the active integrated amplifier antenna array are 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 200 g and effective radiated power of 25.6 dBm is fabricated and operated at 2.45 GHz
