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.

无线载波在射频和微波频段频谱的短缺，促使世界各地的许多研究小组探索未来宽带无线通信系统的毫米波频段。例如，60 GHz左右的免授权v波段提供了57至64 GHz范围内的7 GHz带宽，这为短程无线通信开辟了新的机会。利用这个可用的频段，可以部署各种要求高数据速率的无线应用程序。这些应用包括无线高清视频流、多千兆载波级回程链路、成像、安全、点对点无线数据链路取代光链路、视频/音频传输从/到便携式设备，所有这些都需要提供在Gbps范围内的速度。事实上，在这个频段上运行的无线局域网可以很容易地提供大约1.5 Gbps的数据速率，这将提供诸如在蓝光视频播放器和电视之间传输未压缩视频信号之类的尖端技术。然而，在毫米波频段，无线通信系统严重存在路径损耗、用户干扰和多径衰落问题。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能力的先进天线。基于同样的观点，我们提出发展先进毫米波天线的研究计划。为了实现这些具有挑战性的设计，我们将研究新的人造电磁材料，包括超表面、频率选择表面、电磁间隙材料和脊隙波导，并利用它们来实现电磁波的动态传播控制。基于这些方法，本研究计划将设计和开发先进的天线。总之，拟议的研究计划描述了在最近成功的基础上建立和追求几个新的发现方向之间的平衡组合。它将促进人工电磁结构、先进毫米波天线、表征和设备制造和测试等多学科研究，与加拿大工业高科技的特定需求保持一致。特别是，它将有助于(i)设计和开发具有高增益和波束整形能力的毫米波宽带透镜天线，使用智能超表面；（ii）研究和调查使用敏捷频率选择表面的可重构天线；（iii）设计和实施新型相控阵天线；（四）探索和发展以脊隙波导技术为基础的天线；（五）最后，我们将培养高素质的人才，以应对现代社会的科技挑战。
