E-band beam-steering antenna array with substrate integrated frequency selective structures
The exponential growth of data traffic that is facing today’s 3G and 4G operators has urged the international regulatory agencies, like Federal Communications Commission (FCC) and the International Telecommunications Union (ITU), to allocate further spectrum at millimeter-wave bands for 5G wireless standard and beyond. These new parts of the electromagnetic spectrum provide orders of magnitude more bandwidth for wireless communications, and thus would offer high data rates and better quality of service for end-users. However, the design of antenna front-ends for wireless transceivers at these frequencies faces a variety of technical challenges, such as the need for highly directive antenna arrays in order to overcome the enormous pathloss, and the great shadowing and blockage exhibited by millimeter waves. In this Mitacs project, we plan to collaborate with our industrial partner :Huawei Technologies Ottawa in order to study, design and provide hardware prototypes for beam-steering antenna arrays operating in E-band (between 71 and 76 GHz) using a novel and promising technique of frequency selective structures, which enables the design of antenna arrays that provide the same quality of service for users in different spatial regions of the cellular network.
