在这项工作中，我们展示了一种新型的紧凑型机械波束控制发射机的基础上直接垂直集成的2-D MEMS为基础的机械波束控制天线与VCO上的一个单一的硅平台。通过消除长馈线和波导金属块，辐射方向图得到了极大的改善，从而在每个扫描角度都得到了几乎理想的方向图。由馈线和移相器引起的损耗也被消除，这允许发射器仅使用单个VCO来实现。系统复杂性大大降低，总模块尺寸仅为1.5cm × 1.5cm × 0.4cm。同时，本文还提出了一种将MEMS移相器与压控振荡器、功率放大器、功分器和微带天线集成在一起的平面电子波束控制发射机。这项工作表明，RF MEMS可以成为高水平集成的关键技术
In this work, we demonstrate a novel compact mechanical beam steering transmitter based on a direct vertical integration of a 2-D MEMS-based mechanical beam steering antenna with a VCO on a single silicon platform. By eliminating the long feed lines and waveguide metal blocks, the radiation pattern has been improved vastly, resulting in an almost ideal pattern at every scan angle. The losses incurred by the feed lines and phase shifters are also eliminated, which allows the transmitter to be implemented using only a single VCO. The system complexity has been greatly reduced with a total module size of only 1.5cm times 1.5cm times 0.4cm. Also, presented in this paper is a planar electrical beam steering transmitter that integrates the MEMS-based phase shifters with VCO, PA, power divider and microstrip antennas. This work demonstrates that RF MEMS can be a key enabling technology for high-level integration
