本文介绍了一种与旋转的非稳定小卫星（如立方体卫星）建立可靠通信链路的新技术。作者提出了一种多模激励平面圆形阵列无线电与360度移相器相结合的系统，该系统可以电子跟踪旋转的立方体卫星天线并建立通信链路。发射器包括产生模式的罗特曼透镜和微带贴片天线的圆形阵列。作者提出的方法结合了圆阵列的两种空间正交模式。他们首先介绍了系统架构，然后设计并实现了一个在5.8 GHz的c波段工作的概念验证实验验证模块。
This Letter presents a novel technique for establishing a robust communication link to a spinning un-stabilised small satellite such as a CubeSat. The authors propose a system that involves a multimode excited planar circular array radio combined with a 360 degrees phase shifter that can electronically track the spinning CubeSat antenna and establish a communication link. The transmitter comprises a mode-generating Rotman lens and a circular array of microstrip patch antennas. The authors' proposed approach combines two spatially orthogonal modes of the circular array. They first present the system architecture, then they design and realise a proof-of-concept experimentally validated module operating in C-band at 5.8 GHz.
