Abstract
We demonstrate a high-gain and low-profile dielectric cuboid antenna (DCA) at J-band for terahertz (THz) wireless communication applications. The developed DCA is made of polytetrafluoroethylene (PTFE) and can be connected to a standard waveguide (WR-3.4). The structure is very simple, and the size is in mesoscopic scale; 1.36${\mathrm {\lambda \times 1.36 \lambda \times 1.79 \lambda (1.36\ mm \times 1.36\ mm \times 1.79}}$ mm for 300 GHz). The simulated antenna gain of the DCA was 15.5 dBi. We characterized the DCA at 300 GHz based on the near-field electro-optic sensing technique and far-field transformation. The measured full widths at half maximum of the far-field pattern were 23° and 24° for E-pane and H-plane, respectively, showing good agreement with simulated value.
