加拿大的信息和通信业是一个具有战略意义的国家利益领域，正在获得惊人的增长，特别是在无线部门。例如，根据加拿大工业部的统计数据(NAICS类别33422)[1]，从2002年到2011年，加拿大的无线和通信设备制造业经历了12.5%的年均增长。市场继续受到移动应用和设备、多媒体和卫星服务以及无线传感器需求增长的推动。射频系统是这些技术中的关键和实质性部分，负责高效地接收、过滤和发送其收发机前端的高频信号。*最近，晶片级薄膜和基于微/纳米技术的系统被用来超越传统器件的限制，为性能优越的小型化集成系统铺平了道路。微/纳米技术有三个独特的特点，在射频界引起了高度关注。这些特点是小型化、多样性和微电子兼容性。小型化显然是微纳技术的重要组成部分，可以建造尺寸极小、性能极高的部件和子系统。多样性是微机械加工所固有的，它允许同时制造成百上千个零件，就像一个零件一样容易。微电子兼容性允许微机械系统与微电子系统在单个芯片上的单片集成，具有成本、尺寸、可靠性和性能方面的优势。*在这项研究中，将利用微技术的优势来推进毫米波前端系统。这些好处源于机械系统对微尺度的良好缩放行为以及它们传输射频信号的能力。我们将开发包含微电子机械元件的高质量小型化毫米波可重构圆片级波导系统。最终的目标是使结构具有较小的形状系数和根据需求调整传递函数的能力。在许多情况下，这样的组件不仅可以显著降低尺寸、重量、功耗和组件数量，还可以提供卓越的性能和额外的功能。

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.
