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学、遥感、等离子体诊断和军事情况下的尘雾成像等领域。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。这项研究将为避碰系统、着陆系统、小型便携式通信系统等许多民用应用领域打开大门。提供高性能和更便宜的接收机也将增强射电天文和遥感的应用领域。本文提出的研究计划如下：1)利用高效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，采用新开发的90 GHz低噪声放大器，采用平面天线和CPW（共面波导）匹配网络，形成具有增益的低噪声接收机。2)利用与天线耦合的平面变容管和晶体管等固态源产生100-1000 GHz的高效辐射。将研究允许锁相和扫频的不同电路配置。输出可以用作接收机设置中的本地振荡器或用作近距雷达应用的发射机。

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.
