摘要： Over the past years, interest in wireless THz communications with so-called T-waves has tremendously increased [1]–[4], because the large carrier frequencies in the range 0.2 THz to 0.9 THz support wide signal bandwidths and consequently large data rates. Transmission over hundreds of meters and line rates exceeding 100 Gbit/s were demonstrated [5]–[10]. Typical atmospheric losses are 0.2 dB/100 m at 0.2 THz, 0.5 dB/100 m at 0.3 THz, 1.5 dB/100 m at 0.4 THz, and 5 dB/100 m at 0.9 THz. For transmission over a 100 m-distance, however, the unity-gain free-space propagation loss dominates. To combat this propagation loss, multiple directional antennas with a high gain per sector can be employed at the base station to boost the reach and the data throughput on transmission and reception.
