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.

在许多现有和下一代通信系统中，特别是在雷达、卫星通信和遥感领域，对低成本自适应天线的需求非常普遍。虽然反射面天线在许多应用中很有用，但它们只能通过机械扫描，导致灵活性和可靠性有限。另一方面，提供高速波束扫描的天线阵列由于其巨大的硬件占用空间而非常昂贵。最近，可重新配置的反射镜已经成为一种前景看好的低成本替代方案，它结合了这些平台的最佳特性。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了应用。Ingegneria Dei Sistemi(Ingegneria Dei Sistemi)是海军、航空、航空导航、地球雷达和空间系统领域高科技解决方案开发的全球领先者。该项目的目的是开发精确的分析和设计工具，用于在入侵检测系统生产的商业天线设计工具中对可重构反射阵进行建模。这将使最终用户能够轻松地成功设计和分析这一新兴的天线架构，使该天线架构扩展到更多的商业应用中，同时为入侵检测系统及其客户提供独特的功能。该项目在加拿大的信息和通信技术部门在技术开发以及培训高素质人员方面具有广泛的益处。
