Sub-band-Multiplexed Multi-User Data Communication in mmWave and THz with Analog True Time Delay Arrays
Wideband millimeter-wave (mmWave) and terahertz (THz) systems can facilitate simultaneous data communication with multiple spatially separated users. It is desirable to orthogonalize users across sub-bands by deploying frequency-dependent beams with a sub-band-specific spatial response. True-Time-Delay (TTD) antenna arrays are a promising wideband architecture to implement sub-band-specific dispersion of beams across space using a single radio […]
