Abstract. The design and development of a multiband ceramic material-based optical antenna are discussed. A square-shaped aperture is utilized to excite the silicon-based dielectric resonator. This type of excitation system provides the capability to create a triple hybrid mode (HEM11δ, HEM12δ, and HEM11δ + 2) inside the cylindrical-shaped ceramic material. Due to this feature, the proposed aerial is operating over diverse frequency bands, i.e., 117.5 to 140 THz, 158 to 165.5 THz, and 175.2 to 190.5 THz, respectively. Stable radiation characteristics as well as the good value of gain (about 4.0 dBi) make the proposed nanoradiator applicable for hyperspectral imaging system (125 THz) and VLC for wireless LAN (160 / 180 THz).
