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.
