Wireless devices represent multi-billion dollar industries in Canada, and drive our lives and economy like never before with a desire for tiny communication and sensor devices and networks that are changing the way we interact with each other and gather data about the environment around us. The relentless pursuit of device miniaturization for such systems often comes at the price of compromised performance, at a time when the requirement is for increased functionality. One of the biggest obstacles to further miniaturization of wireless devices is the passive circuit elements responsible for signal conditioning, and also the radiating antenna element. These passive structures account for a large portion of the size. This project is an international collaboration, proposing a radically different approach to fabrication of compact wireless devices using non-traditional ultra-thick polymer-based materials, enabling improved performance and increased functionality for various emerging wireless communication devices, automotive radar systems, small satellites, RF identification, and sensors/biosensors. Specialized techniques for microfabrication of high performance wireless structures using synchrotron-based deep X-ray lithography will be used to fabricate very tall structures (up to millimetres), in thick metal, polymer, and polymer-dielectric composite layers, with high-aspect-ratios and exceptional structural features down to the micrometer range. Lithography will be used to directly fabricate dielectric resonator antenna elements and combine these with tall embedded metal structures and circuits for the first time, to realize vertical integrated wireless devices with new capabilities and enhanced functional properties.

无线设备代表着加拿大数十亿美元的产业，并以前所未有的方式推动着我们的生活和经济，人们对微型通信和传感器设备和网络的需求正在改变我们彼此互动的方式，并收集有关我们周围环境的数据。这种系统对器件小型化的不懈追求往往是以牺牲性能为代价的，而此时的要求是增加功能。无线设备进一步小型化的最大障碍之一是负责信号调节的无源电路元件以及辐射天线元件。这些被动结构占了很大一部分的大小。 该项目是一项国际合作，提出了一种截然不同的方法，使用非传统的超厚聚合物基材料制造紧凑型无线设备，为各种新兴无线通信设备、汽车雷达系统、小型卫星、射频识别和传感器/生物传感器提供性能改进和功能增强。使用基于同步加速器的深X射线光刻技术进行高性能无线结构微制造的专业技术将用于在厚金属、聚合物和聚合物-电介质复合层中制造非常高的结构（高达毫米），具有高纵横比和高达微米范围的特殊结构特征。 光刻技术将被用于直接制造介质谐振器天线元件，并首次将这些元件与高嵌入式金属结构和电路联合收割机相结合，以实现具有新功能和增强功能特性的垂直集成无线设备。
