Analysis tools for reconfigurable reflectarrays

在许多现有的和下一代通信系统中，特别是在雷达、卫星通信和遥感领域，普遍需要低成本的自适应天线。虽然反射器天线在许多应用中是有用的，但它们只能被机械扫描，从而导致有限的灵活性和可靠性。另一方面，提供高速波束扫描的天线阵列由于其大的硬件占用而非常昂贵。最近，可重构反射阵列已经成为一个有前途的低成本的替代方案，结合了这些平台的最佳功能。这些天线在汽车雷达、毫米波通信系统和航空航天系统中得到应用。Ingegneria Dei Sistemi（IDS）是海军、航空、空中导航、测地雷达和空间系统领域高技术解决方案开发的全球领导者。本项目旨在开发精确的分析和设计工具，用于在IDS生产的商业天线设计工具中对可重构反射阵列进行建模。这将使最终用户能够轻松地成功设计和分析这种新兴的天线架构，使这种天线架构能够扩展到更多的商业应用中，同时为IDS及其客户提供独特的功能。该项目在加拿大信息和通信技术部门的技术开发以及高素质人员的培训方面具有广泛的效益。

The need for low-cost adaptive antennas is widespread in many existing and next-generation communication systems, particularly in the areas of radar, satellite communications and remote-sensing. While reflector antennas are useful in many applications, they can only be mechanically scanned resulting in limited agility and reliability. On the other hand, antennas arrays, which offer high speed beam-scanning are tremendously costly due to their large hardware footprint. Recently, reconfigurable reflectarrays have emerged as a promising low-cost alternative that combines the best features of these platforms. These antennas are finding applications in automotive radars, mm-wave communication systems, and aerospace systems. Ingegneria Dei Sistemi (IDS) is a global leader in the development of high-technology solutions in the fields of naval, aeronautical, air navigation, georadar, and space systems. This project is aims to develop accurate analysis and design tools for modelling reconfigurable reflectarrays in a commercial antenna design tool produced by IDS. This will enable end users to successfully design and analyze this emerging antenna architecture with ease, allowing this antenna architecture to expand into a greater number of commercial applications while at the same time providing unique capabilities to IDS and their customers. This project has broad benefits within the information and communication technology sector in Canada terms of technology development as well as the training of highly qualified personnel.
