Emerging Technologies for Steering Narrow Antenna Beams in Modern Radio Systems

In many modern wireless radio systems, tight link budgets demand the two antennas in the transmitting and receiving terminals, or at least one of them, to have high antenna gains, which in turn require highly directive (narrow) antenna beams. In this invited presentation, we will review some currently used and emerging methods for steering continuously such antenna beams, with focus on non-specialist audience who are expected to attend this conference, including electrical and electronic engineers practicing in relevant industries.
