Active Integrated Antenna Front-End Technology for Future Millimeter-Wave Wireless Communications

该提案将解决成功实施未来一代毫米波无线通信系统的三个重要且高度协同的技术挑战，即在统一环境下的设备，天线和传播。为了优化设计高效发射放大器和具有自适应能力的高灵敏度接收器，将广泛探讨有源集成天线的概念。例如，将开发一种新型的用于谐波调谐和功率组合的集成平面天线的推挽功率放大器，以及集成了我们最近发明的准八木天线的宽带mmic兼容接收阵列。为了达到提出的设计目标，非常规的CAD方法，如全球天线/电路/设备EM仿真，以及高度集成射频前端的独特测量技术，也将被研究。

This proposal will address three important and highly synergistic technical challenges for successful implementation of future generation millimeter-wave wireless communications systems, i.e., device, antenna and propagation, within a unified context. The concept of active integrated antennas will be explored extensively for optimal designing of both high-efficiency transmitting amplifiers and high-sensitivity receivers with adaptive capabilities. For instance, a novel push-pull power amplifier with integrated planar antennas for harmonic tuning and power combining, and a broadband, MMIC-compatible receiving array integrated with our recently invented quasi-Yagi antennas will be developed. To reach the proposed design objectives, unconventional CAD approaches such as global antenna/circuit/device EM simulation, and measurement techniques unique to highly integrated RF front ends, will be investigated as well.
