Show more >This paper presents the validation of a wireless communication link in the THz range using a photonics-based transmitter and a waveguide-fed micromachined wideband flat array antenna. Combining several carrier frequencies over the 320-400 GHz band, we show that the antenna can handle an aggregated data-rate beyond 0.3 Tbit/s. Using over-the-air calibration measurements, the corporate-fed array antennas were characterized to 36 dBi gain from 320 to 400 GHz. Moreover, the antenna dispersion is analyzed over the entire antenna band. A detailed comparison between back-to-back and 0.5 m wireless distance performance is realized, to confirm that the over-the-air power penalty of the data link fits with the link budget measurements realized using the S-parameter measurements of the whole THz channel. We show that by leveraging the full antenna bandwidth, aggregated data-rate reaches 0.3 Tbit/s using 16-quadrature amplitude modulation and various baud rates.Show less >
