Development of Novel Coextruded High-Q Structures, Photonic Bandgap Antennas and Ultra-Low Power MEMS-Based Electronics for 5 GHz and 28 GHz Communication Systems

9979428 RebeizPIs建议为4.9 GHz(或5.7 GHz)和28 GHz应用开发微型低功耗前端。FCC选择了这些频率用于相对较短距离(从建筑物内30米到室外使用的3-5公里)的宽带高数据速率通信。目前，低噪声放大器、平衡混频器、中等功率放大器和压控振荡器/锁相环等系统的电子学(硅和砷化镓器件)已经相当成熟。实际上，射频前端的选频滤波器、射频振荡器的高Q谐振器结构、平面高效天线等片外组件才是目前低成本前端的限制组件。他们还建议研究新的、在某些情况下具有革命性的方法，以建立非常高Q值的谐振器、低损耗过滤器和高效率天线。

9979428RebeizThe PIs propose the development of miniature low-power front-ends for 4.9 GHz (or 5.7 GHz) and 28 GHz applications. FCC has selected these frequencies for wideband high-data rate communications over relatively short distances (from 30 m inside buildings to 3-5 km for outdoor use). Currently, the electronics (Si and GaAs devices) for such systems as low-noise amplifiers, balanced mixers, medium power amplifiers, and the voltage-controlled oscillators/phase-locked loop are quite mature. Actually, it is the off-chip components such as the frequency selection filters for the RF front-end, high-Q resonator structures for the RF oscillators, and the planar high-efficiency antennas which are currently the limiting components in low cost front-ends. They also propose to investigate novel, and in some cases, revolutionary, approaches to build very high-Q resonators, low-loss filters, and high efficiency antennas.***
