Nowadays mobile communication systems are experiencing a substantial demand in data rates due to a large number of emerging applications that include mobile communications, data transfer and intelligent transport. This very large data traffic is expected to continue increasing in the next decade. To achieve this high data traffic, mm-wave bands could be explored to provide multi-Gbps broadband access to mobile users. With this feature, mm-wave bands are seen as key technology enablers for future 5G wireless mobile networks. However at mm-wave bands, wireless communication systems using conventional antenna systems suffer from high path loss, which reduces their performances significantly in terms of coverage and capacity. To overcome these challenges, we propose in this project to develop new electronically tunable metamaterials with desirable electromagnetic properties and apply them for the design of advanced metamaterial-based reconfigurable antennas with dynamic radiation pattern capability to offer reliable and compact alternative to current mm-wave antenna technologies. To address this objective, first we will conduct theoretical as well as experimental investigations on metamaterial unit cells at millimeter-wave bands. This will be followed by the design and development of reconfigurable antennas with dynamic radiation pattern using these newly developed materials whose properties appear promising. The broad vision of this project starting from the development of new metamaterial unit cells to its industrial applications makes this project unique and of critical importance for the future 5G and beyond wireless communication systems at mm-wave bands.The proposed project will take advantage of our research team's strong expertise in both antenna design and metamaterials. Research efforts will be oriented towards the design of new tunable metamaterial structures to use them for developing reconfigurable antennas with dynamic radiation pattern. The new knowledge that will emerge from this project and the training of highly qualified personnel associated to the different stages of this work will certainly contribute to enhance Canada's global competitiveness in this high-technology sector.

如今，由于包括移动通信、数据传输和智能传输在内的大量新兴应用，移动通信系统正在经历着对数据速率的巨大需求。这种非常大的数据流量预计将在未来十年继续增长。为了实现这种高数据业务量，可以探索毫米波频段以向移动用户提供多Gbps宽带接入。凭借这一功能，毫米波频段被视为未来5G无线移动网络的关键技术推动者。然而，在毫米波频段，使用传统天线系统的无线通信系统存在高路径损耗，这大大降低了其覆盖范围和容量方面的性能。为了克服这些挑战，我们在这个项目中建议开发具有良好电磁性能的新型电子可调谐超材料，并将其应用于基于超材料的先进可重构天线的设计，具有动态辐射方向图能力，以提供可靠和紧凑的替代当前毫米波天线技术。为了达到这个目标，我们首先对毫米波波段的超材料单胞进行了理论和实验研究。随后将利用这些新开发的材料设计和开发具有动态辐射方向图的可重构天线，这些材料的性能似乎很有希望。该项目从开发新的超材料单元电池到其工业应用的广阔愿景使该项目独一无二，对未来5G及以后的毫米波无线通信系统至关重要。研究工作将致力于设计新的可调谐超材料结构，以用于开发具有动态辐射方向图的可重新配置天线。这一项目将产生的新知识以及与这项工作的不同阶段有关的高素质人员的培训，必将有助于提高加拿大在这一高技术部门的全球竞争力。
