Abstract

Toward the orbital demonstration of a solar power satellite (SPS), a breadboard model of the SPS has been developed for preliminary experiments including wireless power transmission. The model forms a thin panel structure with a thickness of 6 cm, and the panel consists of three layers being functionally assigned to a transmission antenna, microwave amplification and control, and thermal radiation, respectively. Microwave amplified up to 160 W is emitted from a large-scale phased array antenna with 256 microstrip elements. In order to evaluate the effect of multiply arranged antennas to the emission, the measurement of the radiation pattern is conducted for different relative positions of the antenna panels. Additionally, the steering of the transmission beam is achieved as an initial demonstration for retrodirective control.

面向太阳能卫星轨道实验的无线输电板的微波特性

为实现太阳能卫星的在轨演示，建立了太阳能卫星的面包板模型，并进行了包括无线输电在内的初步实验。该模型采用厚度为6 cm的薄板结构，由三层组成，功能分别为传输天线、微波放大与控制、热辐射。由256微带元件组成的大型相控阵天线发射的微波放大功率可达160 W。为了评估多天线布置对发射的影响，对天线面板的不同相对位置进行了辐射方向图测量。此外，传输光束的转向作为逆向控制的初步示范。
