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.
