Presidential Young Investigator Award: Millimeter-Wave Integrated Antennas and Receivers

毫米波辐射的传统应用领域是射电天文、遥感、等离子体诊断、军事场合的尘雾成像等。我的总统青年研究员研究工作的目的是开发低成本的毫米波集成天线、接收器和发射系统。这项研究将为许多民用应用领域打开大门，如防撞系统、着陆系统、小型便携式通信系统等。提供高性能和更便宜的接收器也将加强射电天文和遥感应用领域。提出的研究计划如下：L)利用高效率集成喇叭天线和肖特基二极管研制100-500 GHz低噪声平面接收机。此外，使用新开发的90 GHz低噪声放大器与平面天线和CPW(共面波导)匹配网络，以导致具有增益的低噪声接收器。2)从耦合到天线的平面变容二极管和晶体管等固态源高效地产生100-1000 GHz的辐射。将研究允许锁相和扫频的不同电路配置。该输出可用作接收器设置中的本机振荡器，或用作近距离雷达应用的发射器。

The traditional application areas of millimeter-wave radiation are in the fields of radio-astronomy, remote sensing, plasma diagnostics, and imaging through dust and fog in military situations. It is the purpose of my Presidential Young Investigator research effort to develop low-cost millimeter-wave integrated antennas, receivers and transmitting systems. This research will open the doors to many civilian application areas such as collision avoidance systems, landing systems, small portable communication systems, etc. Providing high performance and less expensive receivers will also enhance the radio-astronomical and remote- sensing application areas. The proposed research plan is as follows: l) Develop 100-500 GHz low-noise planar receivers using high- efficiency integrated horn antennas and Schottky- diodes. Also, use newly-developed 90 GHz low-noise amplifiers with a planar antenna and a CPW (coplanar-waveguide) matching network to result in a low-noise receiver with gain. 2) Generate efficiently 100-1000 GHz radiation from solid-state sources such as planar varactors and transistors coupled to antennas. Different circuit configurations that allow phase-locking and frequency sweeping will be investigated. The output can be used as local oscillator in a receiver set-up or as a transmitter for short-range radar applications.
