Abstract
We demonstrate short-range terahertz (THz) wireless transmission using a high-gain and low-profile dielectric cuboid antenna (DCA) in the 300 GHz band. The compact DCA will support high-speed mobile user equipment (UE) in the next generation. The simple rectangular structure enables easy installation and we configures the current design to a standard waveguide (WR-3.4). The DCA was developed with polytetrafluoroethylene and has dimensions of 1.36λ × 1.36λ × 1.79λ (1.36 mm × 1.36 mm × 1.79 mm at 300 GHz). Antenna patterns of the DCA at 300 GHz were evaluated using a near-field electro-optic sensing technique. The far-field pattern calculated from the measured near-field pattern showed good agreement with simulation results. The calculated antenna gain was 15.5 dBi. The wireless transmitter configured with the developed DCA has been demonstrated in the 300 GHz band. The resultant data rate with amplitude-shift keying of 17.5 Gbit/s was achieved at transmission distance of 79 mm.
