Miniaturized Reconfigurable Microfabricated Waveguide Circuits

加拿大的信息和通信产业是一个具有战略意义的国家利益领域，特别是在无线领域。例如，根据加拿大工业部的统计数据（NAICS类别33422），加拿大的无线和通信设备制造业从2002年到2011年平均每年增长12.5%。对移动应用程序和设备、多媒体和卫星服务以及无线传感器的需求不断增加，推动了市场的发展。射频系统是任何这些技术的关键和实质性部分，并负责有效地接收、滤波和发送高频信号在其收发器的前端。

The information and communications industry in Canada is an area of strategic national interest that is enjoying phenomenal growth, especially in the wireless sector. For example, wireless and communications equipment manufacturing in Canada has experienced a 12.5% average annual growth from 2002-2011, according to Industry Canada statistics (NAICS category 33422) [1]. The market continues to be fueled by increased demand for mobile applications and devices, multi-media and satellite services, and wireless sensors. Radio frequency systems are a critical and substantive portion of any of these technologies, and are responsible for efficiently receiving, filtering, and sending the high frequency signals at the front end of their transceivers. Recently, wafer-level thin film and micro/nano technology-based systems have been used to surpass the limits of conventional devices and pave the way for miniaturized integrated systems with superior performance. There are three unique features of micro/nano technology that attract a high level of attention in the radio frequency community. These characteristics are miniaturization, multiplicity, and microelectronics compatibility. Miniaturization is clearly an important part of micro/nano technology, allowing the construction of components and subsystems that are both extremely small in size and high in performance. Multiplicity is inherent in micro-machining processing, which allows hundreds or thousands of components to be created concurrently and as easily as one. Micro-electronic compatibility allows the monolithic integration of micromechanical systems with microelectronics on a single chip, with benefits to cost, size, reliability and performance. In this research, the benefits of micro-technology will be used to advance millimeter-wave front-end systems. These benefits arise from the favorable scaling behavior of mechanical systems to micro scale dimensions and their ability to transmit radio frequency signals. We will develop high quality miniaturized millimeter-wave reconfigurable wafer-level waveguide systems that incorporate microelectromechanical components. The ultimate goal is to have structures with small form factor and the capability of adapting the transfer function to demand. In many cases, such components would not only substantially reduce the size, weight, power consumption and component counts, but also promise superior performance and additional functionality.
