*The frequency spectrum shortage facing wireless carriers at RF and microwave bands has motivated many research groups worldwide for exploring millimeter-wave bands for future broadband wireless communication systems. For instance, the unlicensed V-band around 60 GHz offers a 7-GHz bandwidth in the range from 57 to 64 GHz, which has opened new opportunities for short-range wireless communications. Using this available band, various high-data rate demanding wireless applications could be deployed. These applications include wireless high-definition video streaming, multi-gigabit carrier-grade backhaul links, imaging, security, point-to-point wireless data links replacing optical links, video/audio transfer from/to portable devices, all of which are required to provide speeds in the Gbps range. Indeed, wireless local area networks operating at this band can easily offer a data rate of about 1.5 Gbps, which would provide cutting-edge technology such as the transfer of an uncompressed video signal between a blue-ray video player and a television.***However at millimeter-wave bands, wireless communications systems suffer seriously from path loss, presence of user interference and multipath fading problems. To overcome this issues, advanced antennas with high gain, broadband operation, and beamforming capabilities are urgently required. In the same perspective, we propose research program to develop advanced antennas operating at millimeter-wave bands. To realize these challenging designs, we will investigate new artificial electromagnetic materials, including metasurfaces, frequency selective surfaces, electromagnetic gap materials and ridge gap waveguides, and use them to achieve dynamic electromagnetic wave propagation control. Based on these approaches, advanced antennas will be designed and developed in this research program.***In conclusion, the proposed research program describes a balanced mix between building on recent successes and pursuing several novel directions of discovery. It will foster focused multidisciplinary research in artificial electromagnetic structures, advanced millimeter-wave antennas, characterization and device fabrication and testing, consistently with specific needs of the high technology in Canadian industry. In particular, it will contribute to (i) design and develop millimeter-wave wideband lens antennas with high gain and beam-shaping capabilities using smart metasurfaces; (ii) study and investigate reconfigurable antennas using agile frequency selective surfaces; (iii) design and implement novel phased array antennas; (iv) explore and develop ridge gap waveguide technology-based antennas, and (v) last but not least, we will train highly qualified personnel to respond to the scientific and technological challenges of modern society.

*RF和Microwave乐队面临的无线载体面临的频谱短缺促使全世界的许多研究小组探索毫米波频段，以实现未来的宽带无线通信系统。例如，无执照的V波段约为60 GHz，在57至64 GHz的范围内提供了7 GHz的带宽，这为短距离无线通信提供了新的机会。使用此可用频段，可以部署各种高数据率要求的无线应用程序。这些应用程序包括无线高清视频流，多Gigabit载波级回程链接，成像，安全性，点对点无线数据链接替换光学链接，视频/音频传输从/到便携式设备，所有这些链接都需要在GBPS范围内提供速度。确实，在该乐队运行的无线局域网可以轻松地提供约1.5 Gbps的数据速率，这将提供尖端的技术，例如在蓝射线视频播放器和电视之间传输未压缩的视频信号。为了克服这一问题，迫切需要具有高增益，宽带操作和波束形成功能的高级天线。从同一角度来看，我们提出了研究计划，以开发在毫米波频段运行的先进天线。为了实现这些具有挑战性的设计，我们将研究新的人工电磁材料，包括元整日，频率选择性表面，电磁间隙材料和脊间隙波导，并使用它们来实现动态电磁波传播控制。基于这些方法，将在该研究计划中设计和开发高级天线。它将在人工电磁结构，先进的毫米波天线，表征和装置制造和测试中培养以人工电磁结构的多学科研究，并遵循加拿大工业高科技的特定需求。特别是，它将有助于（i）使用智能metasurfaces设计和开发具有高增益和横梁成型功能的毫米波宽带镜头天线； （ii）使用敏捷频率选择表面研究和研究可重构天线； （iii）设计和实施新颖的阶段阵列天线； （iv）探索和开发基于技术的山脊间隙波导的天线，（v）最后但并非最不重要的一点是，我们将培训高素质的人员，以应对现代社会的科学和技术挑战。
