作为有源集成天线技术应用的一个实例，给出了用于空间太阳能卫星2000系统微波功率传输的有源集成放大器天线阵的设计方法和实验数据。该阵列中单元单元的堆叠结构由三层组成：放大电路层、辐射层和耦合层。通过将2/SPL×/2单元单元与定向耦合器和FET放大器相结合，制成了重量为200g、有效辐射功率为25.6dBm的轻型单元接线板，并在2.45 GHz下工作。
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/spl times/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.
