为了实现卫星的高数据速率和远距离通信，需要卫星上的大口径天线。然而，在空间中制作高平整度表面是困难的，目前对卫星大型天线的研究都采用了高平整度结构。在本研究中，为了在可展开膜结构上构建反射天线，我们提出了一种主动反射天线，它通过变容二极管主动调节元件的反射相位，并补偿低平面表面。通过对非平面反射光的分析，验证了本文提出的方法。
For high data rate and long-distance communication of satellite, a large aperture antenna on satellite is required. However, it is difficult to make high flatness surface in space and the current study on large antennas for satellites assumes the high flatness structures. In this study, to construct the reflectarray antenna on the deployable membrane structure, we propose the active reflectarray which actively adjusts the reflection phase of elements by varactor diodes and compensate the low flatness surface. We analyze the nonflat reflectarray and confirm our proposed method.
