Abstract
This chapter presents the antenna arrays for beamforming and beam-steering in the mmW and THz frequency ranges based on phased arrays and leaky-wave antennas. The common feature of the presented approaches is that the antenna emitters (AE) are fed by high-speed photomixers. This enables photonic control of the phase in the antennas and introducing the delays in optical domain for true time-delay steering. Among the beamforming approaches presented, the first one uses dielectric rod waveguide technology for coupling the radiation out of the substrate with wideband performance, while the other two are planar antennas.
