The development of knowledge and skills for the next generation information and communicationstechnologies are of highest strategic interest to the Huawei Canada CRC.Antenna arrays have become part of the standard configuration in 5G wireless communication systems. Inorder to enhance the accessibility and capability of the millimeter-wave systems, antennas with polarizationdiversity and high gain have become more and more necessary. Additionally, with the implementation ofbeamforming in the 5G radio, an integrated front end solution is a must in order to be compatible with a typicalhandset form factor. An effective antenna size reduction becomes indispensable in order to make the systemcompact. The available mm-Wave antenna systems suffer from the difficulty to achieve a high gain and widesteering range simultaneously. This engage research project with collaboration of Huawei Canada CRC aims atdeveloping a family of dual polarization 5G phased array antenna designed to cover the 26.25-30 GHzfrequency band.Phased array approaches can achieve the wide steering range but need higher element counts to achieve therequired gain, whereas lens (or focal plane) antennas can achieve high gain and low side lobe level but withlimited steering range. The objective of this research is to explore the possibility of combining these twotechniques in achieving their respective benefits for use in next generation wireless communication system.The developed planar antenna can be used either as a stand-alone, or combined to support multi-beam, hybridbeamforming and MIMO functionality. Lens will ensure the gain enhancement to the required level with largetwo dimensional scan volume in azimuth and elevation.The unique mm-Wave antenna technology that will be developed through this project should give a realadvantage to the industrial partner. Research on phased array antennas will help the partner to effectivelydeploy radio access infrastructure necessary to support a 5G future.

下一代信息和通信技术的知识和技能的发展是华为加拿大CRC的最高战略利益。天线阵列已成为5G无线通信系统标准配置的一部分。为了提高毫米波系统的可达性和容量，具有极化分集和高增益的天线变得越来越必要。此外，随着5G无线电中波束成形的实现，集成前端解决方案是必须的，以便与典型的手机外形兼容。一个有效的天线尺寸减小变得必不可少，以使系统紧凑。现有的毫米波天线系统难以同时实现高增益和超宽范围。该研究项目与华为加拿大CRC合作，旨在开发一系列覆盖26.25-30 GHz频段的双极化5G相控阵天线。相控阵天线可以实现宽的转向范围，但需要更高的单元数来实现所需的增益，而透镜（或焦平面）天线可以实现高增益和低副瓣水平，但转向范围有限。本研究的目的是探讨结合这两种技术的可能性，以实现各自的优势，用于下一代无线通信系统中，所开发的平面天线可以作为一个独立的，或结合使用，以支持多波束，混合波束成形和MIMO功能。透镜将确保增益增强到所需的水平，在方位角和仰角上具有大的二维扫描体积。通过该项目开发的独特毫米波天线技术将为工业合作伙伴提供真正的优势。相控阵天线的研究将帮助合作伙伴有效部署支持5G未来所需的无线电接入基础设施。
