Monolithic Integrated Phase Shifters for Electronic Beamforming in the High Millimeterwave Frequency Range

这个后续方案的重点是研究和实现毫米波雷达和通信系统的多通道相控阵系统，基于初始项目阶段的成果。研究的重点是信道的相互耦合以及移相器与辐射天线的接口。此外，在初始项目阶段发现的新的有源模拟和无源数字移相器概念应该进一步详细研究。电路行为的分析研究将允许一个优化的移相器设计。最后，将对成功的概念进行研究，并根据小型化和输入功率的线性度进行定制。此外，将研究开发的移相器与现有的频率捷变天线阵列的结合，作为二维波束转向系统的基础。

The emphasis of this sequel proposal is the investigation and realization of a multi-channel phased array system for millimeter wave radar and communication systems, based on the results of the initial project phase. The focus of the investigations is on the mutual coupling of the channels as well as the interface of the phase shifter and the radiating antenna. In addition the novel active analog and passive digital phase shifter concepts found in the initial project phase should be investigated in further detail. The analytical investigation of the behavior of the circuits will allow for an optimized phase shifter design. Finally the successful concepts will be investigated and tailored in terms of miniaturization as well as linearity with respect to input power. Furthermore the combination of the developed phase shifters with an existing frequency-agile antenna array will be investigated as a basis of a 2D-beamsteering system.
